Contents
An environment created in a user’s machine from an on-line application stored on the cloud and run through a web browser.
In addition, the platform provides on demand services, that are always on, anywhere, anytime and anyplace.
The hardware and software services are available to general public, enterprises, corporations and business markets

Service Content
Most known and first service, major service given as part of cloud computing 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.
Consumer does not manage or control the underlying cloud infrastructure including network, services, operating systems, storage
E.g. Google Apps, Microsoft Office 365, Gmail, Hotmail, Picasa, Salesforce
Software-as a Service (SaaS)
Give us API(Application Programming Interface) and take care of the implementation.
It is a platform for developers to write and create their own SaaS i.e application.
In this model, cloud providers delivers a computing platform and/or solution stack typically including operating system, programming language execution environment, database and web server.
E.g. Google’s App Engine, Amazon EC2, Microsoft Azure
Platform-as a Service (PaaS)
This is computing power that you can rent for a limited period of time.
An evolution of web site and server hosting services which provided servers and virtual private servers.
Cloud providers offer computers as physical or more often as virtual machines, raw storage, firewalls, load balancers and networks.
E.g. AT&T-Hosting and Storage, Windows Azure, HP, Amazon EC2
Infrastructure-as a service(IaaS)
Public Cloud Used by multiple tenants on a shared basis Hosted and managed by cloud service provider Limited variety of offerings Lower upfront cost Economies of scale Simpler to manage OpEx E.g. Amazon, Google, Microsoft, Sales force
Types of Cloud
Private Cloud Exclusively used by a single organization Controlled and managed by in-house IT Large number of application Lower total cost Greater control over security, compliance &
quality of service Easier Integration CapEx & OpEx E.g. HP data center, IBM, Sun, Oracle
Types of Cloud
Hybrid Cloud Usage of both public and private together called
hybrid cloud Organization may host critical apps on private
clouds.
Types of Cloud
Virtualization is “ something which is not REAL, but displays the full qualities of the REAL.
Virtualization Provides:-Hardware Platform-Operating System-Storage device-Network resources- Software implementation
Virtualization
Single OS image per machine Software and hardware
tightly coupled Running multiple application
on same machine often creates conflict
Inflexible and costly infrastructure.
Before Virtualization
Hardware-independence of operating system and applications.
Virtual Machines can be provisioned to any system.
Can manage OS and application as a single unit by encapsulating them into Virtual Machines.
After Virtualization
Why/Why Not Recommend Cloud Computing
Why??y? Achieve economies of scale Reduce spending on
technology infrastructure Back up and recovery Reduce capital cost Improve accessibility Monitor project more
effectively Easy access to information Improve flexibility
Why Not?? Technical Issue Security Prone to attack Lack of Control
Services:- Managed It Security Smart City Solutions Cloud Computing Social Media Integration E-Governance Solutions IT Infrastructure
Modernization Broadband Solutions
Case Study
Allied Digital Services Ltd.
Case StudyClient: Leading Financial Services Group based in California that provides broker-dealer services and advisory programs for approximately 5000 independent financial professionals and more than 700 financial institutions nationwide.

Well defined SLAs improved service availability for business critical applications
Case Study
Key Highlights: Server Availability-100% Improved first call resolution-70% Images Distributed-272 Antivirus Definition updated- 412 Security patches applied-3200 Average SLA compliance Response- 100% Resolution- 99.95%
Conclusion
Cloud Computing is evolved by consolidating several technologies like SaaS, PaaS, IaaS, and Virtualization
Multiple choices as public, private and Hybrid depending on requirement.
3 cloud models: Private, Public and Hybrid Virtualization is economic and cost effective.
