Leverage open technology solutions to meet the
demands of the new application economy
Introduction
Meet the demand for a new application economy
Mobile applications are truly becoming the primary face of many compa-
nies. If an organization’s mobile app is unreliable, or the user has a bad
experience, it will have a direct impact on the overall perception of that
company in the customer’s mind. For example, in 2015, there are more
than 7 billion mobile cellular subscriptions worldwide.1
Leading companies are seizing the opportunity to build, integrate and
support the next generation of applications. They’re using mobile, cloud
and big data analytics in new, more effective ways to drive better business
outcomes and competitive differentiation. To support these strategic
efforts, companies need a flexible and cost-efficient IT architecture to
gain the highest levels of reliability, security and performance.
Although many organizations have already made large investments in IT
systems to meet this demand, they can not afford to continually add
new servers and software licenses to keep pace with growth. Right now,
C-level IT leaders, infrastructure and operations executives, enterprise
and solution architects, developers, and more are exploring better ways
to strike the right balance between controlling cost, complexity and risk
while ensuring they have the agility to proactively deliver innovative
applications and services that drive competitive advantage and market-
place leadership.

IBM Systems
As seen in Figure 1, many of the world’s most innovative orga-
nizations are using Linux and open source technology solutions
to deliver customer-facing, revenue-driving applications that
serve millions of customers, clients and citizens.
However, as Linux and open source deployments move from
niche projects to being more pervasive in the data center to
support the business, it is imperative that these applications be
fully supported by enterprise-grade capabilities such as nondis-
ruptive scalability, unparalleled availability and continuous data
protection. This is especially important for business-critical
applications—the solutions that support an entire organization
and require 24x7 availability.
For any business, outages impacting a business-critical applica-
tion or server infrastructure can be costly in terms of lost reve-
nue, missed opportunity and reduced employee productivity.
To a client’s customers, when applications become unavailable,
that loss of services can diminish the individual experience,
causing a negative effect on loyalty, potentially leading to
customer attrition. Meeting the demands of customers and
service-level agreements (SLAs) hinges on server reliability,
uptime and manageability. Having the right infrastructure
in place will provide an organization with agility and room
for growth.
Unleash the full potential of Linux with IBM LinuxONE.
Linux has been the world’s fastest growing server operating
systems for a number of years and is now a major player in the
global IT market. A Linux infrastructure has to be efficient,
secure, adaptive and integrated. It must be designed to handle
the explosive growth of mobile clients, be able to leverage vast
amounts of data, and provide deep, real-time insights at the
point for greatest business impact—all deployed within a secure
and resilient cloud-ready environment.
IBM clients rely on the enterprise-grade platform for Linux
technology as a trustful, reliable and highly secure system to
confidently deploy business-essential applications, optimize
operating costs and achieve seamless infrastructure growth.
Building on the successful experiences of thousands of customer
engagements and deployments, IBM has delivered a new port-
folio of systems, solutions and services called IBM LinuxONE.
IBM® LinuxONE™ systems and solutions provide users with
a flexible yet powerful infrastructure that helps ensure that
a business receives the performance, reliability, security and
processing power it needs to address increasingly sophisticated
and demanding application requirements.

Enterprise capabilities and insights for secure mobile
applications
Mobile transactions are generating an unprecedented amount
of data, with mobile data traffic predicted to grow globally
10-fold from 2014 to 2019 for a compound annual growth rate
of 57 percent.5
Mobile devices and their ubiquitous access are
causing disruptions for employees and consumers alike, with
more than 90 percent of mobile users keeping their device
within arm’s reach 24x7.6
As users bank, shop, work and manage
their lives on mobile devices, they touch each provider’s system
dozens more times per day than they ever did through websites
and laptops, creating a deluge of transactions and requests. In
2004, each user generated less than a single mobile transaction
per day. By 2014, that number had hit 37 transactions per day,
and continues to spike.7
From a business perspective, a mobile channel represents a
wealth of opportunity to engage in new and interesting ways
to build loyalty, generate revenue and improve enterprise pro-
cesses. At the same time, users expect instant response times,
100 percent uptime, and completely reliable transactions, or
they will switch to a competitor with the touch of a screen.
Ask a Chief Marketing Officer what their ultimate goal is for
reaching current and potential customers, and the answer
will likely be to provide a “demographic of one” experience,
personalized to each individual’s unique interests and buying
behaviors.8
This presents a seemingly daunting challenge to
mobile app and server development teams.
From an IT perspective, multi-channel and device access is
driving digital transformation within IT departments. It is esti-
mated that only 30 percent of the value and effort of a mobile
application is visible via the mobile app, with 70 percent of the
value provided by the infrastructure of software and systems
supporting the mobile workloads.9
IBM LinuxONE combines the open and industry-leading
aspects of Linux with proven qualities of service resulting in
the most scalable enterprise-grade Linux environment.

Trusted and agile cloud deployment
Cloud solutions require always on agility, security and uptime
As market pressures collapse the cycle of innovation into ever
more compressed timeframes, businesses cannot afford to wait
for server infrastructure running at traditional speeds, and
speed isn’t the only constraint. The complexity and scale of
the computing problems businesses are attempting to solve are
growing at an exponential rate. Driven by a ground up rethink-
ing by many businesses regarding the role of computing in
the experience of their customers, business computing is trans-
forming from being a back-office support function to being at
the forefront. Today a customer’s interaction with, and experi-
ence of, a company is often largely (and sometimes completely)
defined by interactions with that company’s software and
services. This is putting unprecedented demands on today’s
compute infrastructure—not just the need to scale with
demand, but also the agility required to keep up with the
mandate for change presented by the needs of the business.

IBM LinuxONE Demo: Scalable Financial Trading Analysis
and Insights
Watch IBM Fellow Donna Dillenberger demonstrate the
new IBM LinuxONE system for scalable financial trading.
The demo shows multiple data loads (live data from the
S&P 500 and Tweets) streaming via Maria DB, MongoDB,
Spark Analytics, Chef, Docker and PostgreSQL, Containers.
In this IBM LinuxONE demo, even with drastic upticks in
CPU utilization during the Greek financial crisis, response
times are still lightning fast. Watch the demo here.
IBM LinuxONE allows up to 50 percent better
response time in analytics than competing platforms
Reduce risk, increase flexibility with diagonal scaling
Database partitioning or “sharding” is a common technique for
scaling out a database that has become too large to fit within
a single server. However, sharding is complex in practice,
and carries risks such as higher latency for aggregate
queries and a lower level of data consistency,. Additionally,
the size of each shard is limited to the size of the servers.
Using IBM LinuxONE allows you to scale out and scale up—
increasing the amount of resources available to each shard
server—in an approach termed “diagonal scaling.” 10
Diagonal scaling allows you to adapt to changing workloads
with industry-leading performance, increased flexibility and
reduced risks, and therefore offers better agility.
Meet regulatory requirements
Another example of achieving improved agility using
IBM LinuxONE systems is high-performance-secure-logging
for auditing in the face of growing regulatory requirements.
IBM LinuxONE Enterprise Data Compression (EDC) facility
allows IBM LinuxONE to offload main processors while
speeding compression by up-to 10x. IBM LinuxONE offers
protected-key function which keeps the encryption key out of
main memory and storage, keeping data-at-rest secure, while
offering 50x better performance than secure-key function.
When combining the speed and capability of EDC and
protected-key function, IBM LinuxONE offers unmatched
agility for quickly, non-intrusively and securely logging snap-
shots of system states such as Docker instances or Apache Spark
Resilient Distributed Dataset (RDDs) for auditing purposes.
Free valuable computing resources
Apart from raw computing power, IBM LinuxONE can speed
compression and encryption with IBM LinuxONE Enterprise
Data Compression and Central Processor Assist for
Cryptographic Functions (CPACF) features. Compressing
Apache Spark Resilient Distributed Datasets (RDDs) or
Docker containers at high speed with little impact on CPU
consumption frees CPU cycles that can be used to perform
more analytics, or faster, non-disruptive auditing of container-
ized applications. By using OpenSSL and openCryptoki
enhanced with CPACF, encrypted transactions will run
faster, and data can be persisted securely and efficiently.
This speed allows the computer to do more work, and gives
you more agility.

Deep innovation and a thriving ecosystem supporting
continuous innovation
IBM has a long history of involvement in open source software
development, and continues to contribute to key open source
technologies such as the Linux kernel, the Eclipse project, and
many Apache projects, including the most recent, Apache
Spark. IBM is a member of many open standard organizations
and software governance consortia that help shape the future
of open source software.11
The IBM Linux Technology Center (LTC) is dedicated to
enabling Linux adoption on IBM platforms and has been con-
tributing continuously to core technologies such as the Linux
kernel, glibc and GCC over the years. But architecture-specific
code is only the tip of the iceberg—and represents only a small
portion of LTC contributions.
Red Hat and SUSE ship enterprise Linux distributions for
IBM LinuxONE systems, and the Ubuntu, Debian and
Fedora distributions also support the architecture. The plat-
form is mature and production-ready, and is able to run most
applications you would expect to run on a Linux server.
Today, more than 40 commonly used open source products run
right out of the box, with more coming on board in future. By
listening to clients, working with business partners and ISVs,
and engaging the open source development community, IBM is
working to bring more foundational open source technologies
to IBM LinuxONE and, further enabling and encouraging the
most sought after software developers to develop solutions
that work on the platform—with a strong emphasis placed on
programming languages and run-time technologies.
IBM is investing heavily to create a rich, open source ecosystem
to enable IBM LinuxONE as the premier platform for new
Linux-based application deployments that exploit emerging
technologies such as Node.js, MongoDB, PostgreSQL,
MariaDB, Docker, Chef, Puppet and Apache Spark. Additional
focus is placed on open source workloads that can benefit
from the reliability, availability and serviceability (RAS) of
the IBM LinuxONE to bring more business value to users,
including database management systems and cloud infrastruc-
ture, as well as analytics and big data solutions. Table 1 and
Table 2 list some of the key open source technologies that

IBM LinuxONE systems are designed to deliver 100 percent
uptime, over decades—they ship with resilient and redundant
hardware, which ensures continuous operations even in case
of hardware faults. The machines boast higher MTBFs (Mean
Time Between Failure), and support hot-swapping of hardware,
so they do not typically need to be taken offline for service.
The use of IBM GDPS helps automate data replication and
speeds recovery from planned or unplanned outages.
IBM LinuxONE systems are equipped with the world’s fastest
commercially available processor as well as large and efficient
memory cache hierarchy, enabling the IBM LinuxONE
Emperor system to achieve high single-thread performance,
which is ideal for scaling applications to handle the massive
volume of transactions that are typical in today’s enterprise
organizations.

A better balance between risk and opportunity
Every organization is faced with the challenge of building both
trust and value amidst uncertainty. Tasked with improving
business performance while also reducing risk, business and
IT leaders need to feel confident about risk exposures to their
data and infrastructure—all while meeting stringent regulatory
requirements.
For example, as data and analytics become more critical to
the development of business advantage, the need for compre-
hensive data security escalates. In response, many leaders are
implementing stronger security and data privacy measures, in
addition to governance policies, to protect their organization
from both internal and external threats, proactively identify
and manage potential exposure to the risks associated with data
breeches, and comply with industry regulations and combat
infrastructure vulnerabilities throughout the value chain.
The virtualization technologies in IBM LinuxONE Emperor
Systems have been EAL5+ certified. These technologies
offer low overhead and higher virtual machine (VM) density
compared to other platforms, thanks to the advanced resource
over-commit technology in the IBM LinuxONE systems.
As a result, applications that run on IBM LinuxONE can scale
out to thousands of co-located VMs, as the system essentially
becomes a “data center in a box.” What’s more, they make
IBM LinuxONE systems ready for cloud applications with
support for rapid provisioning, multi-tenancy and capacity
scaling on demand.

14
IBM Systems
The co-location of virtualized Linux guests brings significant
benefits to applications that run on IBM LinuxONE systems.
Using IBM HiperSockets™, applications can transfer data from
one VM to another in-memory instead of sending the data
over the network. This type of transfer is more reliable because
there is no physical connection to lose, more efficient because
there is no network latency, and more secure because there
is no wire to tap. Co-location is especially important where
system of engagement applications such as mobile and cloud
frequently need to access system of record data.
The IBM LinuxONE architecture includes hardware support
for cryptography, known as Central Processor Assist for
Cryptographic Functions (CPACF). In the presence of a suit-
able cryptographic co-processor, CPACF supports the use of
protected keys, which balances the speed of in-memory clear
keys and the high security of hardware-backed, tamper-proof
secure keys. The OpenSSL and openCryptoki libraries are able
to exploit these IBM LinuxONE system features to speed clear
key, protected key and secure key cryptography.13
Speed and performance improvements
The IBM LinuxONE Enterprise Data Compress Express
adapter is another feature that distinguishes IBM LinuxONE as
a data-processing powerhouse. It allows applications to off-load
zLib-compatible compression work to a hardware co-processor,
achieving a good compression ratio without consuming CPU
cycles. For databases that employ on-the-fly compression,
exploitation of the IBM LinuxONE Enterprise Data
Compression feature in Linux is expected to improve perfor-
mance by a factor of five. As shown in Figure 2, users will be
able to process more data in the same amount of time and save
on storage costs.

Ease of use
You do not need to learn any new codes or commands to log on
as a guest with SSH and be productive in a familiar Bash envi-
ronment. Graphical user interfaces with remote connection
capability, such as X11 and Xvnc, are also available if you prefer
a graphical desktop environment. Most of the major develop-
ment tools are available for IBM LinuxONE systems. If some
user-space applications are not readily available from distribu-
tions, most of them merely need a simple re-compilation to
be able to run on IBM LinuxONE. Applications written for
modern run-time systems, such as Java, Node.js, and PHP
applications, simply run out of the box. Due to the similarity
and compatibility with other Linux platforms, you can
migrate whole applications stacks from other architectures to
IBM LinuxONE simply and easily, often with just a small
amount of work, typically in hours.
More choices and speed with contemporary
programming languages
Contemporary programming languages provide more choice and
speed on the platform
Application developers on IBM LinuxONE systems can choose
from a variety of modern, popular programming languages and
run-time environments, including Java, Node.js (JavaScript),
Python, Ruby-on-Rails, Scala, Erlang, and Go—and the list
is growing. This variety allows new, modern applications to
be built and run on the IBM LinuxONE platform easily.

allows modern applications to be built and run on
IBM LinuxONE easily.
Deploying Node.js on IBM LinuxONE improves performance
The most notable of these run-time technologies is Node.js. It
is the fastest growing ecosystem for application development.
Since 2012, Node.js has grown at a rate three times faster
than Java with the number of Node.js modules contributed
by developers world-wide surpassing other languages.14
As a
high-performance, highly scalable, event-driven, server-side
JavaScript solution, Node.js has become popular for web
application development—the “N” in the term “MEAN stack”
stands for “Node.js.”
To meet the high demand for Node.js functionality on
IBM LinuxONE systems, IBM has ported the open source
Node.js code to the platform. IBM released IBM SDK for
Node.js 1.2 in early 2015. This SDK is fully compatible with
Node.js version 0.12.15
The SDK enables developers to write
Node.js code on any platform, and test and deploy their appli-
cations on IBM LinuxONE systems. Enterprise users of the
SDK will enjoy the performance and security afforded by the
platform (on the AcmeAir benchmark, IBM LinuxONE out-
performs a comparable distributed server with 2.1 times higher
throughput in RESTful transactions16
), as well as the additional
monitoring and debugging tools that ship with the SDK.
Use the same set of tools and skills to diagnose both
Node.js and Java applications
●●
Using IBM Health Center, users can monitor Node.js
applications and gain valuable insight into application hot
spots, garbage collection activities, memory consumption
and much more.
●●
The IBM Interactive Diagnostic Data Explorer (IDDE) is now
aware of Node.js runtime and JavaScript metadata, giving
users the ability to scan the heap for JavaScript objects or
walk JavaScript stack frames during postmortem analysis.
●●
Both Health Center and IDDE are available at no cost
as part of IBM Support Assistant and on the Eclipse
Marketplace. Support for IBM SDK for Node.js is also
available upon request.

16
IBM Systems
Enterprise users of the SDK will enjoy the performance and
security afforded by the IBM LinuxONE platform (on the
AcmeAir benchmark. IBM LinuxONE Emperor out-performs
x86 by 52 percent17
), as well as the additional monitoring and
debugging tools that ship with the SDK.
●●
Improve application throughput by 200 percent.
●●
Reduce transaction response time by as much as 60 percent.
●●
Boost database performance for SQL and NoSQL.
●●
Gain better per core performance and scalability.
One of the most important benefits from deploying Node.js
on IBM LinuxONE systems is the ability to bring the
processing of web requests to the platform where the data
is hosted (co-location of application and data), which can
improve application throughput by two times, and reduce
transaction response times by 60 percent.18
The enablement
of Node.js on the platform also means that a large number
of open source web application frameworks, such as Express
and Sails.js, are now available to IBM LinuxONE developers.
By deploying Node.js applications on IBM LinuxONE,
you gain all the strengths, security and reliability of
IBM LinuxONE. For example, IBM LinuxONE systems fast
processors are well suited to the Node.js single-threaded pro-
cessing model. The large I/O capacity of IBM LinuxONE also
complements one strength of Node.js applications: the ability
to scale and maintain thousands of concurrent connections.
IBM LinuxONE systems can further provide an advantage to
JavaScript applications that need to access enterprise data and
transactions. Logical partitions on IBM LinuxONE systems
can be linked together by high-speed networking HiperSockets,
allowing memory-to-memory communication with drastically
improved performance. JavaScript applications can leverage
HiperSockets transparently to access data and transactions in
other logical machines inside the box.

the community version. The IBM SDK was built from the
open source community code base with extensions added
for support on IBM LinuxONE. Leveraging the strength
of monitoring and debugging tools developed for Java, they
have been extended to work with the IBM SDK for Node.js.
NoSQL? No problem.
NoSQL databases are increasingly being adopted in big data
and real-time analytics applications. Some of the most
important NoSQL databases include MongoDB (the “M” in
“MEAN stack”), MariaDB, Apache Geode, Apache Cassandra,
Apache CouchDB and Redis.
IBM LinuxONE delivers two times the performance for the
same SQL and NoSQL databases running on commodity
Linux platforms.
PostgreSQL achieves up to 2.2x better
pgbench throughput over alternative
platforms
Open source relational database management systems such as
PostgreSQL serve a great amount of data in many organiza-
tions. First released in 1996, PostgreSQL is a well-established
enterprise-grade database system that powers many web sites
and government agencies.19
PostgreSQL 9.4 already runs well
on IBM LinuxONE Emperor, and it is able to capitalize on
the strengths of the system as a data-serving platform.
IBM LinuxONE offers many features that others systems
cannot match—including availability, stability, and flexibility—
that combine to help PostgreSQL excel as a powerful
enterprise database solution. An independent performance
test conducted by 2ndQuadrant found that PostgreSQL on the
IBM LinuxONE infrastructure provides greater throughput,
regardless of the type of workloads, compared to an infrastruc-
ture based on a competitive architecture. According to a
report by the PostgreSQL consultancy firm 2ndQuadrant,20
PostgreSQL can offer better per-core performance of 1.6 to
2.2x via pgBench benchmark and scalability on the platform
compared to distributed systems, as shown in Figure 4.
Figure 4 shows, PostgreSQL can offer better per-core performance
and scalability on IBM LinuxONE systems compared to
distributed systems.

Porting, performance measurement and scaling
advantages with MongoDB
MongoDB is a cross-platform document-oriented database.
Released under a combination of the GNU Affero General
Public License and the Apache License, MongoDB is free
and open-source software. Since its initial release in 2009,
MongoDB has been adopted as back-end software by a number
of major websites and services. Today, MongoDB is one
of the fastest-growing database ecosystem, with over
10 million downloads, thousands of customers, and more
than 1,000 technology and service partners.
Classified as a NoSQL database, MongoDB eschews the tradi-
tional table-based relational database structure in favor of
JSON-like documents without fixed schemas. The schema-less
nature of MongoDB not only makes it better than relational
databases at handling unstructured and sparse data, it also
facilitates rapid prototyping and fast evolution of programs
without paying the constant costs of updating database schemas
and refactoring tables.
By adopting JSON/BSON as the document format, MongoDB
allows developers to write data queries in JavaScript, a language
with which they are already familiar, so that the need to mix
SQL statements into the application code can be eliminated.
It also eliminates the cost of ORM (object-relational mapping),
because JSON documents can contain complex types and are
by nature JavaScript objects. Because JSON is widely supported
as a de-facto standard for information exchange, it is easy to
consolidate data from multiple disparate sources into one
MongoDB collection.
MongoDB also supports geospatial and time-series analytics,
as well as scalability and high availability through sharding and
replication, making it a highly capable engine for processing
the vast amount of data generated online. All these factors
help make programs easier to develop and maintain, boost
programmer productivity and improve business agility.
Advantages of running MongoDB on IBM LinuxONE
systems
By deploying MongoDB on IBM LinuxONE systems, organiza-
tions gain all the strength, security and reliability of an
enterprise-grade Linux platform. IBM LinuxONE is equipped
with the fastest processors in the world, and is an I/O
superhero for data and transaction processing throughput.
●●
The speed of the processors available in an IBM LinuxONE
system and its high input/output system, multiple layers
of cache mean that MongoDB can scale up, as well as
scale out.
●●
The enterprise virtualization capabilities of IBM LinuxONE
support very high virtual machine density and resource
over-commit, which allows MongoDB instances to achieve
much better utilization than on other platforms.
●●
Co-located MongoDB instances (different shards, or replica
set members within the same shard) can leverage
HiperSockets (high-speed internal communication pipes) to
reduce network communication overhead.
●●
Proximity to enterprise data that resides on the
IBM LinuxONE allows MongoDB to eliminate extracting,
transforming, and loading (ETL) off platform, removing
latency and improving data security and governance.

19
IBM Systems
Big data is becoming more prevalent as we start to leverage
insights from structured and unstructured data together to
deliver better business outcomes. MongoDB represents a
powerful aggregation point where insights from traditional
system-of-record data (such as retail transaction history) can be
joined with system-of-engagement data (such as micro-beacon
geodesic information) to provide a rich and comprehensive user
experience for the shopper. On top of this, MongoDB database
aggregation now enables businesses to bring these two worlds
together for their own benefit and gain access to insights to all
of their data to facilitate critical business decisions.
Advantages of using MongoDB with IBM LinuxONE
You can easily build and run MongoDB on IBM LinuxONE.
Running MongoDB on IBM LinuxONE enables faster and
more secure access to data sources for aggregation purposes
and eliminates the need for sharding. The performance and
virtualization capabilities of the IBM LinuxONE platform
also make it ideal for scaling out as well as scaling up NoSQL
applications.
Up to 2x better throughput on

No need for sharding
The superior single-thread performance and large memory
capacity of IBM LinuxONE allows MongoDB to scale up very
well. On various Yahoo Cloud Service Benchmark (YCSB)
workloads, MongoDB running on a IBM LinuxONE Emperor
is able to achieve up to two times better throughput than the
latest distributed platforms.
Because IBM LinuxONE can support a maximum of 10 TB of
memory, a single Linux system can accommodate a larger data-
base that would have required sharding to multiple MongoDB
servers on commodity platforms. This affords users the flexibil-
ity to reduce or avoid the risks and costs associated with
sharding.
MongoDB drivers for various languages, such as C/C++,
Node.js and Ruby, either have been verified to work on
IBM LinuxONE or are being ported to the platform.
IBM is working to contribute all the changes upstream to
the latest version of the product.

Three simple use cases using MongoDB on IBM LinuxONE
●●
Aggregate data from multiple sources into a central reposi-
tory to create a single 360-degree view of enterprise custom-
ers. Complex queries can be performed over the aggregated
data efficiently.
●●
Exploit the flexible data model and multiple options for
scaling—including range-based, hash-based and location-
aware sharding—to develop applications quickly, and support
the constantly changing requirements. Schemas can be
radically changed while running in production, with zero
impact on the user experience.
●●
Create a read-forward cache of system of record data for fast
viewing or manipulation by a front-end system, such as a web
application or a mobile application, which could be in use by
a large number of concurrent users.
Compatible IBM products and services working
with MongoDB
MongoDB is currently available on BlueMix via MongoLab, a
fully-managed cloud database service featuring high availability,
automated backups, web-based tools, monitoring and support.
Since version 10.5, DB2 has provided JSON support.
One way that DB2 users can interact with JSON data is to
deploy the MongoDB wire listener, which intercepts the
MongoDB wire protocol and acts as a gateway in front of
DB2—which allows DB2 to accept and respond to requests
from applications written against the MongoDB API. Any
modern language with a driver that supports the MongoDB
protocol can be used, including Node.js, PHP, Python and
Ruby, as well as more traditional languages such as C, C++,
Java and Perl.
Throughput improvements with MariaDB on
IBM LinuxONE
MariaDB is a community-developed fork of the popular
MySQL relational database management system, and it is
intended to remain free under the GNU GPL. Being a fork of
a leading open source software product, it is notable for being
led by the original developers of MySQL, who forked the code
due to concerns over its acquisition by Oracle. Contributors are
required to share their copyright with the MariaDB
Foundation.
MariaDB achieves up to 2.1x better
Sysbench OLTP throughput on
IBM LinuxONE over alternative platforms
MariaDB delivers value with:
●●
Backward compatibility with MySQL
●●
Perpetually open source
●●
More cutting-edge technologies and more storage engines
than MySQL
IBM LinuxONE offers state-of-the-art hardware,
world-class security and the capability to scale MariaDB with
IBM’s industry-leading virtualization technologies. Clients
can easily consolidate clusters with many servers on a single
IBM LinuxONE system. IBM LinuxONE can host more serv-
ers per core than any other system with high-speed encryption,
disaster recovery and continuous availability solutions.
Common use cases for MariaDB
Many clients and partners use MariaDB as an alternative to
MySQL and Microsoft SQL Server because MariaDB future-
proofs their database investment, obtains better value, and
developers and IT departments want to leverage the default
database from their Linux distributions and simplify deploy-
ments. The combination of Linux, Apache, MySQL/MariaDB,

Collaboration with the MariaDB community
IBM actively contributes to the MariaDB community to
ensure that the latest MariaDB works out of the box on
IBM platforms. The effort includes fixing bugs, porting
new features and optimizing for the underlying hardware
platform. For example, IBM has recently built and validated
MariaDB with Galera Cluster capability on IBM LinuxONE.
IBM works with MariaDB, Inc. to deliver MariaDB Enterprise
for IBM platforms and 24/7 support services to IBM customers
with business and mission-critical application needs. This has
helped many IBM customers running Linux, and IBM has now
extended the partnership to cover IBM LinuxONE systems.
Compatible IBM products and services working

Advances to large-scale data processing
New options for analytics
Big data and real-time analytics are the key to success for many
enterprises. Apache Spark is an open source cluster computing
framework that allows user programs to load data into a
cluster’s memory and query it repeatedly.
As data and analytics are embedded into the fabric of business
and society—from popular applications to the Internet of
Things (IoT)—Apache Spark brings essential advances to
large-scale data processing. First, it dramatically improves the
performance of data dependent applications. Second, it radically
simplifies the process of developing intelligent applications,
which are fueled by data.
Apache Spark is agile, fast and easy to use, and because it is
open source, it is improved continuously by a worldwide
community. Apache Spark is designed to perform both batch
processing and new workloads, such as streaming, interactive
queries and machine learning.
New options for analytics allow data scientists to take advantage
of IBM LinuxONE advanced analytic capabilities without
having to worry about the specific format of the data.
The enablement of Apache Spark for IBM LinuxONE allows
data mining specialists to use Apache Spark’s common pro-
gramming framework to take advantage of IBM LinuxONE
advanced analytic capabilities without having to worry about
the specific format of the data.
●●
Apache Spark running on IBM LinuxONE produces 1.5x
faster insights for real-time analytics than on alternative
platforms.
●●
Process 54 percent more data
Based on internal IBM testing, the Apache Spark-Perf bench-
mark suite on IBM LinuxONE can process 54 percent more
data (see Figure 2) than distributed systems for model building,
leading to real-time insights with higher accuracy.

Application portability and infrastructure flexibility
Docker delivers ease of use and application portability
Docker is an open, portable, light-weight run-time and packag-
ing tool for Linux containers, and has gained a lot of momen-
tum since its first release in 2013. Linux containers provide
operating system-level virtualization for running multiple
isolated applications on the same host. Using containers,
it is easy to build and ship complex applications that have
dependencies on a deep software stack or other infrastructure,
without having to worry about interference from other applica-
tions that might have conflicting requirements. Compared to a
standard virtual machine, containers are much faster to boot,
more efficient to run, and offer higher application density.

Docker is an open source tool that provides a way of
running isolated applications and software in a single
Linux instance in what are called “containers.”
●●
Package applications together for more efficient deploy-
ment and better density
●●
Develop the app package on any platform, provide the
binaries for the platform, and deploy the app anywhere—on
a laptop, in the datacenter, or in a public cloud
●●
Gain traction as a way to contemporize Linux environments
in datacenters
●●
Eliminate virtual machine resource overhead since the
hypervisor is not required
●●
Enable full support of DevOps model through simple
build process of containers, versioning and deployment
●●
Scale stateless solution components, such as node.js
instances, easily
Docker provides developers with more ease of use, portability
and the ability to quickly get up and running, providing users
will the ability to develop anywhere. Docker has an engine or
runtime that sits on top of the operating system and provides
the virtual containers into which users deploy the software.
Docker offers an elegant portability solution for applications
and software packages because it is lightweight and removes
some of the complexities of managing a hypervisor, e.g. KVM,
or VMware. However, if users want security they need to pack-
age them as second level guests to get the isolation between the
applications and data.
Advantages using Docker on IBM LinuxONE
The virtualization technology in IBM LinuxONE complements
Docker by offering a more powerful, scalable and secure
environment. For example, while developing or testing an
application, a user can obtain increased application density by
deploying containers directly on one Logical Partition (LPAR),
which eliminates the need for VM provisioning.
Why Docker and IBM LinuxONE are a perfect match:
●●
Easy app deployment: Docker on IBM LinuxONE allows
unparalleled simplicity in application packaging and
deployment.
●●
More efficient communication: With the ability to collocate
hundreds of thousands of containers sharing the same
memory subsystem, inter-container communication comes
close to the speed of a memory-to memory copy with
HiperSockets.
●●
Security: Expensive SSL calls that would have been needed
on a distributed system are no longer necessary since
communication is done through secure in-memory
channels.
●●
Faster and simpler auditing: Docker image snapshot
creation is as much as 4x faster due to dedicated compres-
sion cards; state rollback can happen in a heartbeat and
the system can be ready for auditing at a much more
granular level.
●●
More reliability: With IBM GDPS™, container storage is
virtually guaranteed 99.9999 percent uptime which means
more operational efficiency by eliminating the need for
replication that would typically be required.
●●
Makes Docker secure: With the ability to spawn a Linux
guest in seconds (or ideally, overcommit), Docker contain-
ers can offer security levels that VM level isolation brings to
the table, while maintaining the simplicity and flexibility of
deployment that containers offer.
When deploying applications in production, users can put the
containers inside second-level guests to get better isolation.
For maximum security, users can run individual containerized
applications inside separate LPARs, which gives isolation
on a bare-metal level that is unmatched by other platforms.
See Figure 10 for an illustration of how containers can run
on LPARs as well as VMs.

IBM LinuxONE application performance per Docker container
is higher with a high number of containers per virtualized or
physical resources. Its low hypervisor overhead allows Docker
containers that are running on second level VM guests to have
minimal impact on application performance while providing
full security isolation in a multitenant enterprise environment.
In addition to the main Docker tools, IBM is working to
provide Docker files that allow users to create containerized
applications of their choice to run on IBM LinuxONE.
Four simple use cases
1. Faster more efficient deployment: write applications once
Clients can write an app once, send to other people and then
deploy which means organizations do not have to develop
resources with special knowledge about how to install the app
and what other packages are required. The containers provide
the user with the automation for packaging with automated
scripts inside the container, providing an easier, more efficient
and faster way to deploy and run applications.
2. Break down the components of applications: choose only what
is needed to build what your organization wants
Let’s say a developer has an app that requires lots of parts for a
multi-tiered application comprised, for example, by a workflow
component, a WebSphere component, a database component,
and a math library component. One option is to put them in
four different containers. Then, if the workflow component is
not wanted, the user only needs to deploy three of the contain-
ers. The user is able to break down applications into different
parts and use only the necessary pieces. Many software products
are often shipped with the entire product included—in order to
access the one component that is needed, the user is required
to install the full complement of the application’s pieces. If an
app requires all the components, the user can put them in one
container. If the app doesn’t require all components the user has
the option to keep them separate—as if the pieces are optional.
The flexibility of being able to select only what is to be used—
like building blocks, enables users to more efficiently build what
they want.

3. Simple application portability: Develop Java applications on one
platform and deploy on multiple platforms
A developer can develop applications in Java on an Intel plat-
form and deploy them on IBM LinuxONE. Since Java doesn’t
require a recompile on different platforms, app portability is a
given. Without containers, the developer didn’t know if they
had the right libraries, Java VM level, and middleware require-
ments. But now with containers, any software the app requires
can be packaged into a container, provided it is Java. Although
the container has to be rebuilt on the platform image the
developer is using, once the developer is in a container model
this task becomes simple.

4. Enable more applications in one system: Docker on
IBM LinuxONE allows for larger density than VMs
Docker allows for larger density than VMs and enables more
applications in one system. Before containers, a user could
only run 10 WebSphere instances on an Intel system, but now
with containers and enhanced memory efficiency; the user
can run hundreds of the same instance because you don’t have
to set up separate VMs with hypervisors.
IBM LinuxONE offers advantages over commodity
x86 with memory overcommit, while the overhead on an
IBM LinuxONE with CPU virtualization is relatively small.
Users will see a bigger advantage in the distrusted environment
leveraging containers, however more importantly, the combina-
tion of containers and security isolation due to this memory
overcommit means lower VM overhead.
In a Docker environment that leverages density, the user loses
the security isolation between these applications because the
hypervisor is not present. If security is not a priority, then
running on bare metal gives good density at faster response
time. However, if your organization is concerned about
security, then you will want isolation, and the overhead on
the IBM LinuxONE is minimal.
Organizations running mission critical applications can leverage
density/bare metal in a development-test environment to
rapidly put everything on one IBM LinuxONE partition to
eliminate the provisioning associated with hypervisors. In
production, you can revert back to second level guests to
get the isolation, and live with the hypervisor overhead as the
production environment does not change rapidly. You can use
this VM isolation on a tenant granularity to get the isolation on
a tenant base, and on sufficient “mass” of applications to gain
from the efficiency opportunities because VMs don’t have as
big overhead on IBM LinuxONE as compared with that on a
distributed x86 platform.
With IBM LinuxONE users can shape their environment with
system virtualization and container elements according to the
landscape and requirements without limitations in performance.
This means organizations can define their IT structures
according to their needs, not their system constraints.

IBM internal studies and are as follows: Public Cloud configuration: total
of 219 instances (128 for light workloads, 64 for medium workloads and
27 for heavy workloads); x86 Cloud configuration: total of eleven
x86 systems each with 24 Intel E7-8857 v2 3.0GHz cores, 512GB
memory, and 7x400GB SSDs; LinuxONE Emperor Cloud configura-
tion: total of 32 Linux cores, 3806GB memory, and Storwize v7000 with
47x400GB SSDs. Price comparison estimates based on a 3YR Total Cost
of Ownership (TCO) using publicly available U.S. prices (including a
20% discount for middleware) current as of January 1, 2015. Public
Cloud TCO estimate includes costs (US East Region) of infrastructure
(instances, data out, storage, support, free tier/reserved tier discounts),
middleware and labor. LinuxONE Emperor and x86 TCO estimates
include costs of infrastructure (system, memory, storage, virtualization,
OS, cloud management), middleware, power, floor space and labor.
Results may vary based on actual workloads, system configurations,
customer applications, queries and other variables in a production
environment and may produce different results. Users of this document
