What is Cloud Computing? Massive computing resources, deployed among virtual datacenters, dynamically allocated to specific users and tasks and accessed as a service via an user interface (UI), such as a web browser. The physical cloud resources may reside in a number of locations, the details of which are not typically known to the service’s users. Cloud resources are offered as a service on an as needed basis. The cloud itself typically consists of large numbers of commodity-grade servers, harnessed to deliver highly scalable and reliable on-demand services.

What is Cloud Computing? Massive computing resources, deployed among virtual datacenters, dynamically allocated to specific users and tasks and accessed as a service via an user interface (UI), such as a web browser.
The physical cloud resources may reside in a number of locations, the details of which are not typically known to the service’s users.
Cloud resources are offered as a service on an as needed basis. The cloud itself typically consists of large numbers of commodity-grade servers, harnessed to deliver highly scalable and reliable on-demand services.
Why Cloud Computing?

Time-to-market
Cloud Features & Benefits for Users
Highly virtualized and standardized infrastructures
Massive scalability
Fault tolerant & highly reliable
Intra- & Inter-cloud load balance
Instant application deployment
No need to install or update SW or HW; access from any browser
Unlimited use
Always on
Access from anywhere
Many services to choose from
Cloud TechnologiesTechnology Key Feature What’s Missing
Grid Computing Job scheduling across many machines
Difficult to administer; Lacks broad applicability of cloud computing
Virtualization Virtual machines decouple OS from hardware
Fail to fundamentally solve scale and reliability
IaaS Infrastructure-as-a-Service
Computational infrastructure available for rent
Lacks security , vertical solutions,
SaaS Software-as-a-Service
Application availability through the cloud
SaaS is an application on the cloud, not a cloud by itself
Utility Computing Packaged computing, application, and storage sold as a service
Describes a business model, not a technology or architecture
Cloud Computing Alliance Collaborative Partnership
Leaders from Key Verticals
Showcase to the World
Secure Cloud Platform
Instant Application Deployment
Cloud Applications
