WSO2 Analytics Platform
WSO2 Analytics Platform uniquely combines simultaneous real-
time and batch analysis with predictive analytics to turn data
from IoT, mobile and Web apps into actionable insights
2

Analytics Strategy
• We deliver a single platform to address all analytics styles - This was driven
by the increasing market requirement to expand analytics in enterprises
beyond pure BI and start exploiting big data in real time.
• We deliver together
• Batch Analytics: analysis on data at-rest, running typically every hour or
every day, and focused on historical dashboards and reports.
• Real time Analytics: analyze event streams in real-time and detect
patterns and conditions.
• Predictive Analytics: leverage machine learning to create a mathematical
model allowing to predict future behavior.
• Interactive Analytics: execute queries on the fly on top of data at rest.
4

Analytics Strategy
• Focus on supporting high-level, SQL query-like languages across the analytics
platform
• No Java programming involved
• Lowest learning curve
• Client Applications are agnostic of the part of the platform being used, so
customers can increase their usage of the platform without changing their apps.
• Common set of receivers/publishers for all analytics types
• Common format for events
• Leverage leading open source projects such as Storm and Spark and contribute
back (such as Siddhi).
• Even if they are packaged together, each component of the platform can scale
independently
5

Key Differentiators
• Open Source, under Apache 2 license
• Integrated Batch, Streaming, Interactive and Predictive Analytics
• Rich, extensible, SQL-like configuration language
• Rich set of data connectors, which can be easily extended
• Events only need to be published once from applications to the platform, and can
be consumed by batch or real time pipeline.
• Part of the overall WSO2 platform
6

Key Differentiators
• Rich set of data connectors, which can be easily extended
• Integrated with batch analytics (same receivers/publishers architecture)
• Events only need to be published once from applications to the platform, and can
be consumed by batch or real time pipeline.
• Performance on single node satisfies 90% of use cases
7

Market Recognition
• Named as a Strong Performer in The Forrester Wave™: Big Data Streaming
Analytics, Q1 2016.
• Highest score possible in 'Acquisition and Pricing' criteria, and among second-
highest scores in 'Ability to execute' criteria
• The Forrester Report notes…..
“WSO2 is an open source middleware provider that includes a full spectrum of architected-as-
one components such as application servers, message brokers, enterprise service bus, and many
others.
Its streaming analytics solution follows the complex event processor architectural approach, so it
provides very low-latency analytics. Enterprises that already use WSO2 middleware can add CEP
seamlessly. Enterprises looking for a full middleware stack that includes streaming analytics will
find a place for WSO2 on their shortlist as well.”

IoT / Edge Analytics
• We provide a solid foundation for an IoT analytics
solution, should it be for device manufacturers or
device users
• Customers can today:
• React in a few hours, a few mins or a few ms to a
condition, leveraging batch and streaming analytics.
• Implement closed loop control (autonomic
computing) leveraging Machine Learning.
• Embed streaming engine in IoT devices or gateways
• Use a SDK and data agent to directly publish events at
the device hardware level.

Customer Stories
a
12
Experian delivers a digital marketing platform, where CEP plays a key role to analyze in real-time
customers behavior and offer targeted promotions. CEP was chosen after careful analysis, primarily for
its openness, its open source nature, the fact support is driven by engineers and the availability of a
complete middleware, integrated with CEP, for additional use cases.
Eurecat is the Catalunya innovation center (in Spain) - Using CEP to analyze data from iBeacons
deployed within department stores to offer instant rebates to user or send them help if it detected that
they seem “stuck” in the shop area. They chose WSO2 due to real time processing, the variety of IoT
connectors available as well as the extensible framework and the rich configuration language. They
also use WSO2 ESB in conjunction with WSO2 CEP.
Pacific Controls is an innovative company delivering an IoT platform of platforms: Galaxy 2021. The
platform allows to manage all kinds of devices within a building and take automated decisions such as
moving an elevator or starting the air conditioning based on certain conditions. Within Galaxy2021,
CEP is used for monitoring alarms and specific conditions.Pacific Controls also uses other products
from the WSO2 platform, such as WSO2 ESB and Identity Server.
A leading Airlines uses CEP to enhance customer experience by calculating the average time to reach
their boarding gate (going through security, walking, etc.). They also want to track the time it takes to
clean a plane, in order to better streamline the boarding process and notify both the air line and
customers about potential delays. They evaluated WSO2 CEP first as they were already using our
platform and decided to use it as it addressed all their requirements.

caching.algorithm’=‘LRU’)

Operators Summary
a
29
Category Operators
Event Sequencing
e handle out of order events by using a variant of the K-Slack algorithm, which is a
well-known solution to handling disorder in event streams, by buffering data until order
can be guaranteed.
Compensation for missed events is not supported in the current version, but is on the
roadmap. Additionally, we can use filtering to reduce noisy events in a stream (based
on Kalman filter)
Enrichment
Enrichment is done via two ways: event tables to access historical data from any
JDBC data source, and custom extensions to connect to custom source of data, such
as files.
Business Logic
Scripting can be used to add any business logic to any execution plan. JavaScript,
Scala and R are supported out of the box. Additional, customers can easily invoke
custom logic through their own operators.
Transformation
The filter operator can be used to filter streams on a certain set of conditions, which
can be combined via and/or - Conditions can be expressed using mathematical
operators, regular expressions, string manipulation and logical operators. Additional ,
queries allow to select information from input stream, project them to output stream or
new stream, and replace certain elements

Operators Summary

Category Operators
Time Windows
Siddhi provides very strong support for time windows, a domain where an SQL-like query language bring
much simplicity compared to a programing language. Several types of windows are supported, including
sliding and tumbling (batch) windows, time windows starting from a point in time, or CRON-based time
windows. Additionally, we support applying streaming processing to events based on the number of events (
length window), the unicity of events or the frequency of events.
Aggregation/Correlation
Using Join and Pattern operators, we can aggregate and correlate two or more streams of data. Join allows
to join events based on condition, while pattern allows to correlate multiple events based on time, logical
relationship or event counting.
Pattern Matching
We detect patterns based on temporal order (based on arrival order), logical relationship (based or the
logical relationship of 2 events, or counting (to limit the number of events matching the pattern). The pattern
may or may not allow events in between the events the condition. If no foreign event is allowed, the
sequence operator must be used.
Custom
Developers can create their own function, operators , time windows and processing operators. The
extensions are written in Java. Once implemented the operators can be used as any other out of the box
operator or function.
Libraries to support custom operators
Developers use the current operators as reference to develop their own, this is one of the key advantages
with open source distribution. We deliver dozens of extensions on GitHub which can be adapted by 3rd
parties. At the implementation level, implementing an extension just involves extending a well-defined
interface.
Other operators
We support more than 100 custom operators on top of the list above, including geographical operators, for
location-based applications, time series, math, natural language processing, integration with machine
learning models created in PMML or our own Machine Learning product.

and groups can be stored in LDAP, Active Directory, a database or any
custom user store.
• Permissions are assigned to users to access all or parts of the DAS
artifacts , either via the admin console or via APIs. For example, a user
could have the right to use the simulation tools, view statistics, etc. but
won’t be able to deploy applications.
• Auditing
