CLOUD COMPUTING
CLOUD
APPLICATIONS
UTILITY
COMPUTING

... eliminate the need to install
and run the application on the
customer's own computer, thus
alleviating the burden of software
maintenance, ongoing operation,
and support.

… a style of computing where
scalable and elastic IT-related
capabilities are provided as a
service to external customers
using Internet technologies.

In Forrester’s List
of the Top 15
Technology Trends

• An environment created in a user’s machine from
an on-line application stored on the cloud and run
through a web browser.
• In simple Cloud computing is using the internet to
access someone else's software running on someone
else's hardware in someone else's data center.

 Just run it for me!
 also known as On-demand Service.
 is an application that can be accessed from anywhere on the world as
long as you can have an computer with an Internet Connection.
 We can access this cloud hosted application without any additional
hardware or software.
 E.g. : G-mail, Yahoo mail, Hotmail etc..,
 Also they can provide security features such as SSL encryption, a
cryptographic protocol.

 Give us nice API (Application Programming Interface) and
take care of the implementation.
 In the PaaS model, cloud providers deliver a computing
platform and/or solution stack typically including operating
system, programming language execution environment,
database, and web server.
 is a platform for developers to write and create their own
SaaS i.e. applications.
 which means rapid development at low cost.
 E.g.: Salesforce.com, Windows Azure etc.

 also known as hardware as a service.
 is a computing power that you can rent for a limited period of
time.
 allows existing applications to be run on a cloud suppliers
hardware.
 cloud providers offer computers – as physical or more often as
virtual machines – raw (block) storage, firewalls, load
balancers, and networks

 Dynamic- One of the keys to cloud
computing is on-demand
provisioning
 Massively scalable- The service must
react immediately to your needs
 Multi-tenant- Cloud computing, by
its nature, delivers shared services

 Self-service - As a user, you can use
the service as you require
 Per-usage based pricing model - You
should only ever pay for the amount
of service you consume
 IP-based architecture - Cloud
architectures are based on
virtualised, internet based
technologies

 Public Cloud – Available to the general public or large
industry group and is owned by an organisation selling
cloud services
 E.g. : Amazon, Google, Microsoft, Sales force
 Community Cloud – Shared by several organisations and
supports a specific community that has shared concerns
 Private Cloud – Operated solely for an organisation or
company
 E.g. : HP data center, IBM, Sun, Oracle, 3tera
 Hybrid Cloud – Combination of two of the above, they
remain unique entities but are bound together by
standardised technologies

 Cloud operating system that runs just a web browser,
providing access to a variety of web-based applications
that allow the user to perform many simple tasks without
booting a full-scale operating system. Because of its
simplicity, Cloud operating system can boot in just a few
seconds.
 The operating system is designed for Netbooks, Mobile
Internet Devices, and PCs that are mainly used to browse
the Internet.
 From Cloud the user can quickly boot into the main OS,
because Cloud continues booting the main OS in the
background.
 Combining a browser with a basic operating system allows
the use of cloud computing, in which applications and data
"live and run" on the Internet instead of the hard drive.

 Eye OS
 Amoeba OS
 Glide OS
 Start force
 myGoya
 CorneliOS
 Lucid Desktop
 Cloudo, Ghost, Zimdesk, Start force etc.,

 For platform independence.
 Faster and safer access.
 Centralisized storage.
 Huge data analysis.
 Data sharing.
 Better administration.

 Individual users connect to the cloud from
their own personal computers or portable
devices, over the Internet. To these
individual users, the cloud is seen as a
single application, device, or document.
 The hardware in the cloud (and the
operating system that manages the
hardware connections) is invisible.
 Data and instuctions are sent to cloud
system. Here all data is stored.
 All insturctions passed over the network
and information processed in the cloud
only.

 Requires a constant Internet connection.
 Does not work well with low-speed connections.
 Features might be limited.
 Can be slow.
 Stored data might not be secure without proper
administartion.
 Stored data can be lost by hardware failures.

Technical Definition:
The ability to run multiple operating systems on a single physical
system and share the hardware resources

 Both the terms are not synonymous for each other
 Cloud computing is a term that refers to the hosting and
delivery methods used to provide software, platform and
infrastructure services to clients on a remote basis over the
internet
 virtualization refers to the logical creation of an IT resource
that doesn’t physically exist
E.g. Virtual application servers and virtual storage devices
like hard drives.
 Difference : Creation of virtual resources does not depend
on the existence of a cloud computing environment.

 Software as a Service : SaaS is a software delivery
method, and that’s all( tatical )
 Service Oriented Architecture : SOA is a
methodology for designing and automating
business processes(strategic)
This virtual SOA platform makes up a blueprint
that is going to cover the implementation and
development platforms.
 Difference : One is tactical, and the other is
strategic

 Amazon EC2 : largest cloud solution
provider. Provides IaaS and PaaS mainly.
Create your account->select what you want
to rent->pay->super cheap(0.67p/min ).
 Bluemix : developers to start building web and
mobile applications on IBM BlueMix, an open
cloud development platform.No vendor lock in

 Green IT Cloud Computing
 Cloud Computing is Eco-Friendly.
 We can reduce E-waste by using Cloud
Computing i.e. by Infrastructure as a Service
(IaaS).
 Cloud Computing Helps to Accelerate Green
IT
 Can reduce Global Warming too..

RECENT TRENDE IN CLOUD COMPUTING
• Hybrid clouds : Hybrid clouds feature an infrastructure that combines private
cloud security with cost-effective, powerful and scalable public cloud attributes.
• BYOD (bring your own device) : majority of consumer electronics in the world
are mobile devices, "bring your own device" is more relevant than ever in the
world of cloud computing. Now Mobile Device management is a key feature
for cloud computing
• Platform-as-a-Service (PaaS) : reduce their IT costs while increasing application
development through more efficient testing and development methods.
Anticipated to expand from f$3.7 billion to $14 billion worldwide. By 2017
• Big data analytics : The emergence, within the next few years, of big data
analytics as a service will offer businesses of any size an easily attainable and
scalable tool for competing in the global marketplace.
• Graphics as a service : There are a number of new cloud-based graphics
technologies from prominent graphics companies, including NVIDIA and AMD
that allow end users to run high-end graphic design applications with a simple
HTML5 web browser.

• Identity management and protection : It is anticipated that over the next
year, there will be identity management solutions based on new cloud based
security paradigms.
• Web-powered apps : With cutting edge initiatives such as famo.us bringing
new life to HTML via JavaScript, it will not be long before the Internet
becomes the main platform for these applications.
• SMB application protection : This technology allows companies to scan
source code on their web applications for any changes in order to detect
potential cyber attacks and since it is on the cloud, it is available on demand.
• Gamification : by 2014, 70 per cent of Fortune 2000 companies would
have at least one cloud-based application that uses game theory… Gaming
has been changed than ever before.

IEEE PROJECTS ON CLOUD COMPUTING
• Information Flow Control for Secure Cloud Computing : Since IFC
security is linked to the data that it protects, both tenants and
providers of cloud services can agree on security policy, in a manner
that does not require them to understand and rely on the particulars
of the cloud software stack in order to effect enforcement.
• Proactive Workload Management in Hybrid Cloud Computing : to make
the best use of public cloud services along with their privately-owned
(legacy) data centers.
• Cloud-Based Execution to Improve Mobile Application Energy Efficiency To
maximize efficiency, systems must determine the functionality to offload at
runtime, which will require innovation in both automated program
transformation and systematic runtime adaptation.
• Privacy-Preserving Multi-Keyword Ranked Search over Encrypted Cloud
Data : enabling an encrypted cloud data search service is of paramount
importance. Considering the large number of data users and documents in
the cloud, it is necessary to allow multiple keywords in the search request
and return documents in the order of their relevance to these keywords.

 Cloud computing is impossible if you cannot connect to the
Internet.
 Since you use the Internet to connect to both your
applications and documents, if you do not have an Internet
connection you cannot access anything, even your own
documents.
 A dead Internet connection means no work and in areas
where Internet connections are few or inherently unreliable,
this could be a deal-breaker.
 When you are offline, cloud computing simply does not
work.
 Bandwidth Bottleneck
 Lack of control during downtime

 Thus cloud operating system provide a super-computing
power .
 This cloud of computers extends beyond a single
company or enterprise and also home PC’s.
 The applications and data served by the cloud are
available to broad group of users, cross-enterprise and
cross-platform.
 In future every home becomes a smart home by using the
cloud service.
 A revoluation can’t stop by anyone.
