What is Cloud Computing The Problem Statement Scalability of Enterprise Applications – An Issue Success Disaster – Failure due to un-planned demand Increasing Capital Investment on IT Infrastructure The Solution Cloud Computing iPhone Launch Festival Season Sports Event

Scalability of Enterprise Applications – An Issue

Success Disaster – Failure due to un-planned demand

Increasing Capital Investment on IT Infrastructure

What is Cloud Computing “ A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption” Internet Where does the term “Cloud” come from ? “ Cloud” is widely used as a metaphor for the Internet Internet is the foundation of Cloud computing Definition In Simple Terms, Cloud offers… Pay-per-use for computation power Virtually infinite computation resources Automatic on-demand scalability

“ Cloud” is widely used as a metaphor for the Internet

Internet is the foundation of Cloud computing

Pay-per-use for computation power

Virtually infinite computation resources

Automatic on-demand scalability

What is Cloud Computing An Analogy - Electricity “ Computation Power” is now available like Electricity You pay for what you use. You rely on a trusted third-party providers Grid computing is a collection of servers that are clustered together to attack a single problem. For a period of time, the entire resources of the grid are available to an user to tackle a particularly difficult compute problem. - Rich Wolski, University of California Grid Computing Utility Computing Metered use of computational resources Origin from utility services (Electricity) Variants

“ Computation Power” is now available like Electricity

You pay for what you use.

You rely on a trusted third-party providers

Metered use of computational resources

Origin from utility services (Electricity)

Why Cloud Computing Eliminates capacity planning and sizing Prevents ‘success disaster’ Eliminates scalability issues and risk of failure Savings on Capital Investment Savings on Data Center Space, Power and Cooling Minimizes Operational costs Reduces TCO Reduces Risks Re-invest saved Capex on new initiatives Focus on business, not on infrastructure Save on operations manpower Better Budget Utilization Quicker Time to Market Create dev and test environments on the fly Rely on speed & stability of the Cloud provider Remain Competitive

Eliminates capacity planning and sizing

Prevents ‘success disaster’

Eliminates scalability issues and risk of failure

Savings on Capital Investment

Savings on Data Center Space, Power and Cooling

Minimizes Operational costs

Re-invest saved Capex on new initiatives

Focus on business, not on infrastructure

Save on operations manpower

Quicker Time to Market

Create dev and test environments on the fly

Rely on speed & stability of the Cloud provider

Inside a Cloud Virtualized CPUs and Storage Physical Servers across the Globe Software Platform The Cloud Platform Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS) Virtual Servers Virtual Storage Network Routers Java Runtime Web 2.0 Runtime LAMP / WAMP Corporate Email Business Processes CRM, ERP, HR Physical Servers

Inside a Cloud The Cloud Platform Metering, Billing and Rating System Identity Management Self Service Portal Dynamic Provisioning Engine Monitoring and Management Network of Physical Servers controlled by the Cloud Operating System Security Subsystem Cloud Applications The ‘Nuts and Bolts’ of a Public Cloud Facilitates Pay-per-use Enforces Security Statistics, Deployment, Start/Stop Replicates Application on demand Registration, Authentication and Authorization The heart of the “Cloud” The face of the Cloud Virtualized Runtime Environment (Infrastructure & Platform)

Public vs. Private Cloud Cloud Choices Exclusive environment Limited on-demand capabilities Private Cloud On-demand resources, scalability Shared environment Public Cloud Requires Initial Capital Investment Cloud setup within Org’s data center Control on security and audit Based on basic virtualization Limited on-demand scaling On-Premise Private Cloud Exclusive, but hosted by a third party Limited on-demand scaling Expensive than public cloud Cheaper than on-premise private cloud Possibility of co-location Externally Hosted Private Cloud Hybrid Cloud Public + Private cloud

Exclusive environment

Limited on-demand capabilities

On-demand resources, scalability

Shared environment

Requires Initial Capital Investment

Cloud setup within Org’s data center

Control on security and audit

Based on basic virtualization

Limited on-demand scaling

Exclusive, but hosted by a third party

Limited on-demand scaling

Expensive than public cloud

Cheaper than on-premise private cloud

Possibility of co-location
