Docker
Ref: https://www.tutorialspoint.com/docker/
• Docker is a container management service (initial release: March
2013)
• Main features of Docker are develop, ship and run anywhere.
• Docker aims at facilitating developers to easily develop applications,
ship them into containers which can then be deployed anywhere.
• It has become the buzzword for modern world development,
especially in the face of Agile-based projects.

Infrastructure and Software Stack
Ref: Internet/YouTube

Goal: Interoperability

“Shipping”

“Docker”

Docker – Features
• Docker has the ability to reduce the size of development by providing a
smaller footprint of the operating system via containers.
• With containers, it becomes easier for software teams, such as
development, QA and Operations to work seamlessly across applications.
• One can deploy Docker containers anywhere, on any physical and virtual
machines and even on the cloud.
• Since Docker containers are pretty lightweight, they are very easily scalable.

Docker – Components
• Docker for Mac − It allows one to run Docker containers on the Mac OS.
• Docker for Linux − It allows one to run Docker containers on the Linux OS.
• Docker for Windows − It allows one to run Docker containers on the Windows
OS.
• Docker Engine − It is used for building Docker images and creating Docker
containers.
• Docker Hub − This is the registry which is used to host various Docker images.
• Docker Compose − This is used to define applications using multiple Docker
containers.

Traditional Virtualization
• Server is the physical server that is used to
host multiple virtual machines.
• Host OS is the base machine such as Linux
or Windows.
• Hypervisor is either VMWare or Windows
Hyper V that is used to host virtual machines.
• One would then install multiple operating
systems as virtual machines on top of the
existing hypervisor as Guest OS.
• One would then host your applications on top
of each Guest OS.

Docker – Architecture
• Server is the physical server that is used to
host multiple virtual machines.
• Host OS is the base machine such as Linux
or Windows.
• Docker engine is used to run the operating
system which earlier used to be virtual
machines as Docker containers.
• All of the Apps now run as Docker containers.

Container?
Ref: https://www.docker.com/
• Containers are an abstraction at the app layer that packages code
and dependencies together.
• Multiple containers can run on the same machine and share the OS
kernel with other containers, each running as isolated processes in
user space.
• Containers take up less space than VMs (container images are
typically tens of MBs in size), and start almost instantly.

Container (contd…)
• An image is a lightweight, stand-alone, executable package that includes everything
needed to run a piece of software, including the code, a runtime, libraries, environment
variables, and config files.
• A container is a runtime instance of an image—what the image becomes in memory
when actually executed. It runs completely isolated from the host environment by
default, only accessing host files and ports if configured to do so.
• Containers run apps natively on the host machine’s kernel. They have better
performance characteristics than virtual machines that only get virtual access to host
resources through a hypervisor. Containers can get native access, each one running in a
discrete process, taking no more memory than any other executable.

Containers and Virtual Machines
VM
Container

Virtual Machines and Containers
• Virtual machines run guest operating systems - the OS layer in each box.
• Resource intensive, and the resulting disk image and application state is an
entanglement of OS settings, system-installed dependencies, OS security
patches, and other easy-to-lose, hard-to-replicate ephemera.
• Containers can share a single kernel, and the only information that needs to
be in a container image is the executable and its package dependencies,
which never need to be installed on the host system.
• These processes run like native processes, and can be managed individually
• Because they contain all their dependencies, there is no configuration
entanglement; a containerized app “runs anywhere”

Docker containers are lightweight

How does Docker work
Source: Internet

Containers and Virtual Machines Together

Why is Docker needed for applications?
• Application level virtualization.
• A single host can run several
spatial applications for utilization
of resources.
• Build once, deploy anywhere,
run anywhere.
• Better collaboration while
development of applications.

Terminology - Image
• Persisted snapshot that can be run
• images: List all local images
• run: Create a container from an image and execute a command
in it
• tag: Tag an image
• pull: Download image from repository
• rmi: Delete a local image
• This will also remove intermediate images if no longer used

Terminology - Container
• Runnable instance of an image
• ps: List all running containers
• ps –a: List all containers (incl. stopped)
• top: Display processes of a container
• start: Start a stopped container
• stop: Stop a running container
• pause: Pause all processes within a container
• rm: Delete a container
• commit: Create an image from a container

Dockerfile
• Create images automatically using a build script:
«Dockerfile»
• Can be versioned in a version control system like Git or
SVN, along with all dependencies
• Docker Hub can automatically build images based on
dockerfiles on Github

Docker Hub
• Public repository of Docker images
• https://hub.docker.com/
• Automated: Has been automatically built from Dockerfile
• Source for build is available on GitHub

Docker – Usage
• Docker is the world’s leading software container platform.
• Developers use Docker to eliminate “works on my machine” problems when
collaborating on code with co-workers.
• Operators use Docker to run and manage apps side-by-side in isolated
containers to get better compute density.
• Enterprises use Docker to build agile software delivery pipelines to ship new
features faster, more securely and with confidence for both Linux, Windows
Server, and Linux-on-mainframe apps.

Cloud Computing
Cloud computing is a model for enabling convenient, on-demand network
access to a shared pool of configurable computing resources like networks,
servers, storage, applications, and services.
Source: Internet

Green Cloud ?
Source: Internet
• Green computing is the environmentally responsible and eco-friendly
use of computers and their resources.
• In broader terms, it is also defined as the study of designing,
manufacturing or engineering, using and disposing of computing
devices in a way that reduces their environmental impact.
• Green Cloud computing is envisioned to achieve not only efficient
processing and utilization of computing infrastructure, but also minimize
energy consumption.

Cloud Advantages
Source: Internet
• Reduce spending on technology infrastructure. Maintain easy access to information
with minimal upfront spending. Pay as you go based on demand.
• Globalize your workforce on the cheap. People worldwide can access the cloud,
provided they have an Internet connection.
• Streamline processes. Get more work done in less time with less people.
• Reduce capital costs. There’s no need to spend big money on hardware, software or
licensing fees.
• Improve accessibility. You have access anytime, anywhere, making your life so much
easier!
• Minimize licensing new software. Stretch and grow without the need to buy expensive
software licenses or programs.
• Improve flexibility. You can change direction without serious financial issues at stake.

Cloud – Challenge
Source: Internet
• Gartner Report 2007: IT industry contributes 2% of world's total CO2
emissions
• U.S. EPA Report 2007: 1.5% of total U.S. power consumption used by
data centers which has more than doubled since 2000 and costs $4.5
billion
>> Need of Green Cloud Computing….

Importance of Energy
Ref: Dzmitry Kliazovich, University of Luxembourg
• Increased computing demand
• Data centers are rapidly growing
• Consume 10 to 100 times more energy per square foot than a typical office
building
• Energy cost dynamics
• Energy accounts for 10% of data center operational expenses (OPEX) and
can rise to 50% in the next few years
• Accompanying cooling system costs $2-$5 million per year

Impact of Cloud DC on Environment
Source: Internet
• Data centers are not only expensive to maintain, but also unfriendly to
the environment.
• Carbon emission due to Data Centers worldwide is now more than both
Argentina and the Netherlands emission.
• High energy costs and huge carbon footprints are incurred due to the
massive amount of electricity needed to power and cool the numerous
servers hosted in these data centers.

Performance <-> Energy Efficiency
Source: Internet
As energy costs are increasing while availability decreases, there is a need to shift focus
from optimizing data center resource management for pure performance alone to optimizing
for energy efficiency while maintaining high service level performance.

CSP Initiatives
Source: Internet
• Cloud service providers need to adopt measures to ensure that their profit
margin is not dramatically reduced due to high energy costs.
• Amazon.com’s estimate the energy-related costs of its data centers amount to
42% of the total budget that include both direct power consumption and the
cooling infrastructure amortized over a 15-year period.
• Google, Microsoft, and Yahoo are building large data centers in barren desert
land surrounding the Columbia River, USA to exploit cheap hydroelectric
power.

 Increasing adoption of sensing technologies (e.g.,
RFID, cameras, mobile phones)
 Internet has become a source of real time
information (e.g., through blogs, social networks,
live forums) for events happening around us
 Cloud computing has emerged as an attractive solution for dealing
with the “Big Data” revolution
 By combining data obtained from sensors with that from the
internet, we can potentially create a demand for resources that can
be appropriately met by the cloud
Ref: Tan, Kian-Lee. "What's next?: Sensor+ cloud!?." Proceedings of the
Seventh International Workshop on Data Management for Sensor
Networks. ACM, 2010

Wireless Sensor Network (WSNs)
• Seamlessly couples the physical environment with the digital world
• Sensor nodes are small, low power, low cost, and provide multiple functionalities
– Sensing capability, processing power, memory, communication bandwidth, battery power.
• In aggregate, sensor nodes have substantial data acquisition and processing capability
• Useful in many application domains – Environment, Healthcare, Education, Defense,
Manufacturing, Smart Home, etc.
3

Limitations of Sensor Networks
• Very challenging to scale sensor networks to large sizes
• Proprietary vendor-specific designs. Difficult for different sensor networks to be
interconnected
• Sensor data cannot be easily shared by different groups of users.
• Insufficient computational and storage resources to handle large-scale applications.
• Used for fixed and specific applications that cannot be easily changed once deployed.
• Slow adoption of large-scale sensor network applications.
4

Limitations of Cloud Computing!
 The immense power of the Cloud can only be fully exploited if it is seamlessly
integrated into our physical lives.
 That means – providing the real world’s information to the Cloud in real time
and getting the Cloud to act and serve us instantly.
 That is – adding the sensing capability to the Cloud

Source: Internet
1. Lets go to the
mountain peak!
2. Sounds Good!
I. Please take your lunch as you appear hungry!
II. Carry drinking water – Water at that region is
contaminated
III. Use anti-UV skin cream
3. Map to nearest food outlets
4. Take pictures of restaurants
and send images
6. Your friend is at nearby
restaurant.. Go catch up with her!
5. Menus of restaurants and
recommended foods!

Few insight from the example!
 Cell phone records the tourist’s gestures and activates applications such as camera,
microphone, etc.
 Cell phone produces very swift responses in real time after:
– Processing geographical data
– Acquiring tourist’s physiological data from wearable physiological
– Sensors (blood sugar, precipitation, etc.) and cross-comparing it with his medical records
– Speech recognition
– Image processing of restaurant’s logos and accessing their internet-based profiles
– Accessing tourist’s social network profiles to find out his friends
8
Fact : the cell phone cannot perform so much tasks !
Ref: http://www.ntu.edu.sg/intellisys

Need to integrate Sensors with Cloud!
 Acquisition of data feeds from numerous body area (blood sugar, heat,
perspiration, etc) and wide area (water quality, weather monitoring, etc.)
sensor networks in real time.
 Real-time processing of heterogeneous data sources in order to make
critical decisions.
 Automatic formation of workflows and invocation of services on the cloud
one after another to carry out complex tasks.
 Highly swift data processing using the immense processing power of the
cloud to provide quick response to the user.

What is Sensor Cloud Computing?
An infrastructure that allows truly pervasive computation using sensors as interface
between physical and cyber worlds, the data-compute clusters as the cyber backbone
and the internet as the communication medium
10
 It integrates large-scale sensor networks with sensing applications and cloud computing
infrastructures.
 It collects and processes data from various sensor networks.
 Enables large-scale data sharing and collaborations among users and applications on the cloud.
 Delivers cloud services via sensor-rich devices.
 Allows cross-disciplinary applications that span organizational boundaries.

Sensor Cloud?
 Enables users to easily collect, access, process, visualize, archive, share
and search large amounts of sensor data from different applications.
 Supports complete sensor data life cycle from data collection to the
backend decision support system.
 Vast amount of sensor data can be processed, analyzed, and stored using
computational and storage resources of the cloud.
 Allows sharing of sensor resources by different users and applications
under flexible usage scenarios.
 Enables sensor devices to handle specialized processing tasks.
11
Sensor cloud enables different networks, spread in a
huge geographical area, to connect together and be
employed simultaneously by multiple users on demand

Overview of Sensor-Cloud Framework

Sensor-Cloud Proxy
 Interface between sensor resources and the cloud fabric.
 Manages sensor network connectivity between the sensor
resources and the cloud.
 Exposes sensor resources as cloud services.
 Manages sensor resources via indexing services.
 Uses cloud discovery services for resource tracking.
 Manages sensing jobs for programmable sensor networks.
 Manages data from sensor networks
• Data format conversion into standard formats (e.g. XML)
• Data cleaning and aggregation to improve data quality
• Data transfer to cloud storage
 Sensor-cloud proxy can be virtualized and lives on the cloud !

14
Sensor Network Proxy
 For sensor resources that do not have direct connection to the cloud, this
component provides the connection.
 Sensor network is still managed from the Sensor-Cloud Interface via Sensor
Network Proxy.
 Proxy collects data from the sensor network continuously or as and when
requested by the cloud services.
 Enhances the scalability of the Sensor Cloud.
 Provides various services for the underlying sensor resources, e.g. power
management, security, availability, QoS.

Another Use case...
• Traffic flow sensors are widely deployed in large numbers in places/ cities.
• These sensors are mounted on traffic lights and provide real-time traffic flow
data.
• Drivers can use this data to better plan their trips.
• In addition, if the traffic flow sensors are augmented with low-cost humidity
and temperature sensors, they can provide a customized and local view of
temperature and heat index data on demand.
• The national weather service, on the other hand, uses a single weather
station to collect environmental data for a large area, which might not
accurately represent an entire region.

Overview of Sensor Cloud Infrastructure

Madoka et al. “Sensor-Cloud Infrastructure Physical Sensor
Management with Virtualized Sensors on Cloud Computing “

Virtual Sensors?
• A virtual sensor is an emulation of a physical sensor that obtains its data
from underlying physical sensors.
• Virtual sensors provide a customized view to users using distribution and
location transparency.
• In wireless sensors, the hardware is barely able to run multiple tasks at a
time and difficult to run on multiple VMs, such as in traditional cloud
computing.
• To overcome this problem, virtual sensors act as an image in the software
of the corresponding physical sensors.
• The virtual sensors contain metadata about the physical sensors and the
user currently holding that virtual sensor.

Virtual Sensor Configurations
(a) one-to-many, many-to-one, and many-to-many, and (b) derived
20
Sanjay et al. “Sensor Cloud: A Cloud of Virtual
Sensors” , IEEE Software, 2014

21
One to Many Configurations:
 In this configuration, one physical sensor
corresponds to many virtual sensors.
 Although individual users own the virtual image, the
underlying physical sensor is shared among all the
virtual sensors accessing it.
 The middleware computes the physical sensor’s
sampling duration and frequency by taking into
account all the users; it re-evaluates the duration
and frequency when new users join or existing users
leave the system.

22
Many to One Configurations:
 In this configuration, the geographical area is divided
into regions and each region can have one or more
physical sensors and sensor networks.
 When a user requires aggregated data of specific
phenomena from a region, all underlying WSNs
switch on with the respective phenomena enabled,
and the user has access to the aggregated data from
these WSNs

23
Many to Many Configurations:
 This configuration is a combination of the one-to-
many and many-to-one configurations.
 A physical sensor can correspond to many virtual
sensors, and it can also be a part of a network that
provides aggregate data for a single virtual sensor

24
Derived:
 A derived configuration refers to a versatile
configuration of virtual sensors derived from a
combination of multiple physical sensors.
 This configuration can be seen as a generalization of
the other three configurations, though, the
difference lies in the types of physical sensors with
which a virtual sensor communicates.
 While in the derived configuration, the virtual
sensor communicates with multiple sensor types; in
the other three configurations, the virtual sensor
communicates with the same type of physical
sensors.
 Derived sensors can be used in two ways: first, to
virtually sense complex phenomenon and second, to
substitute for sensors that aren’t physically
deployed.

25
 Many different kinds of physical sensors can help us answer complex
queries. For example: “Are the overall environmental conditions safe in
a wildlife habitat?”
 The virtual sensor can use readings of a number of environmental
conditions from the physical sensors to compute a safety level value
and answer the query.
 If we want to have a proximity sensor in a certain area where we don’t
have one mounted on a physical wireless node, the virtual sensor could
use data from light sensors and interpolate the readings and the
variance in the light intensity to use as a proximity sensor.

26
A Layered Sensor Cloud Architecture

Summary
 Sensor-Cloud infrastructure virtualizes sensors and provides the management mechanism for
virtualized sensors
 Sensor-Cloud infrastructure enables end users to create virtual sensor groups dynamically by
selecting the templates of virtual sensors or virtual sensor groups with IT resources.
 Sensor-Cloud infrastructure focuses on Sensor system management and Sensor data
management
 Sensor clouds aim to take the burden of deploying and managing the network away from the
user by acting as a mediator between the user and the sensor networks and providing
sensing as a service.

temperature and the parameters of the jacket can be adjusted accordingly
Wireless sensor technology play a pivotal role in bridging the
gap between the physical and virtual worlds, and enabling
things to respond to changes in their physical environment.
Sensors collect data from their environment, generating
information and raising awareness about context.

Internet of Things!
 Extending the current Internet and providing connection, communication, and inter-
networking between devices and physical objects, or "Things," is a growing trend that is
often referred to as the Internet of Things.
 The Internet of Things (IoT) is a scenario in which objects or people are provided with unique
identifiers and the ability to transfer data over a network without requiring human-to-human
or human-to-computer interaction.
 A thing, in the Internet of Things, can be a person with a heart monitor implant, a farm animal
with a biochip transponder, an automobile that has built-in sensors to alert the driver when
tire pressure is low -- or any other natural or man-made object that can be assigned an IP
address and provided with the ability to transfer data over a network

Basic IoT Architecture
6
An IoT platform has basically three building
blocks
 Things
 Gateway
 Network and Cloud

Several Aspects of IoT systems!
 Scalability: Scale for IoT system applies in terms of the numbers of sensors and actuators
connected to the system, in terms of the networks which connect them together, in terms of the
amount of data associated with the system and its speed of movement and also in terms of the
amount of processing power required.
 Big Data: Many more advanced IoT systems depend on the analysis of vast quantities of data. There
is a need, for example, to extract patterns from historical data that can be used to drive decisions
about future actions. IoT systems are thus often classic examples of “Big Data” processing.
 Role of Cloud computing: IoT systems frequently involve the use of cloud computing platforms.
Cloud computing platforms offer the potential to use large amounts of resources, both in terms of
the storage of data and also in the ability to bring flexible and scalable processing resources to the
analysis of data. IoT systems are likely to require the use of a variety of processing software – and
the adaptability of cloud services is likely to be required in order to deal with new requirements,
firmware or system updates and offer new capabilities over time.
7

Several Aspects of IoT systems (contd…)
 Real time: IoT systems often function in real time; data flows in continually about events in
progress and there can be a need to produce timely responses to that stream of events.
 Highly distributed: IoT systems can span whole buildings, span whole cities, and even span the
globe. Wide distribution can also apply to data – which can be stored at the edge of the network or
stored centrally. Distribution can also apply to processing – some processing takes place centrally
(in cloud services), but processing can take place at the edge of the network, either in the IoT
gateways or even within (more capable types of) sensors and actuators. Today there are officially
more mobile devices than people in the world. Mobile devices and networks are one of the best
known IoT devices and networks.
 Heterogeneous systems: IoT systems are often built using a very heterogeneous set of. This applies
to the sensors and actuators, but also applies to the types of networks involved and the variety of
processing components. It is common for sensors to be low-power devices, and it is often the case
that these devices use specialized local networks to communicate. To enable internet scale access
to devices of this kind, an IoT gateway is used

IoT Cloud Systems?
 Recently, there is a wide adoption and deployment of Internet of Things (IoT) infrastructures
and systems for various crucial applications, such as logistics, smart cities, and healthcare.
This has led to high demands on data storage, processing, and management services in
cloud-based data centers, engendering strong integration needs between IoT and cloud
services.
 Cloud services are mature and provide excellent elastic computation and data management
capabilities for IoT. In addition, as IoT systems become complex, cloud management
techniques are increasingly employed to manage IoT components
 Thus, cloud services now act as computational and data processing platforms as well as
management platforms for IoT. From a high-level view, IoT appears to be well-integrated with
cloud data centers to establish a uniform infrastructure for IoT Cloud applications
11
An integration between IoT and cloud services allows
coordination among IoT and cloud services. That is, a cloud
service can request an IoT service, which includes several IoT
elements, to reduce the amount of sensing data or the IoT
service can request cloud services to provision more resources
for future incoming data
