IT – Service Centric View
IT as a service
• Delink from infrastructure
• No more software licensing?
• No more dedicated hardware?
• Rent then the software/hardware and/or service as a whole
• Possible only with IT centric view
Commoditization
• Can I change my server from 2 CPUs to 4 CPUs next week?
― What happens to my current hardware
• Can I change my email service from one provider to the other?
• Can I change my Order Management from one vendor to other?
― Yes, you can always change?
― What happens to my existing data: Migration trouble?
• Resources when you need

Service Centric View – RoI
RoI possible only when viewed in service centric of
• Can I reduce the number of Microsoft Office licenses using cloud model?
Service evaluation
• Service SLA
• Service infrastructure costs – Any SLAs?
― How much are we paying for services?
― How much are we paying for servers?
― How much are we paying for software?
― How much are we paying for network
Evaluate RoI on these investments

Cloud Criteria – Likely candidates
1 • Do you have app candidates that are not frequently used?
• Do you have varying degree of demands
― Need more horsepower in Holiday season
• Do you expect your computing requirements (CPUs, storage, network
services) to grow over a period of time?
― Pay for what you use now. No upfront costs?
― Scale when required
• Support contracts for hardware, servers and network?
― Do you have huge costs?
• Do you have the back up services running only in the night?
― Schedule the backup service and pay for that time only.
• Do you want to share applications across the globe?

Cloud Criteria – Likely candidates …contd
• Platform compatibility
― Do you want to test your apps on multiple platforms?
• Varying load
• Better services at cloud
― Best-of-breed service available at a cheaper price?
• My App can run anywhere
― No dependency on infrastructure
• New deployments of you customers
• Use Microsoft Office in US and India at different times. Pay for one
license only? – Just an example

Cloud RoI
2 • SLA evaluation
― Quantify the SLAs in cloud and non-cloud environments
• Apply Cloud criteria and identify services to migrate to cloud
― Apply RoI for all these services
• Understand the risks
― When is the network down? Whom should I contact?
― What is the process for Fixing IT production issue?
• Decide to move

Cloud Migration
3 • Services identified to migrate
― Quantify the SLAs in cloud and non-cloud environments
• Plan the migration
― Migrate easy ones first: Evaluate RoI and monitor SLA guarantees
― Gain experience
― Migrate the complex ones
• Migrate the application: Pre production stage
― Deploy and test the application
― Scaling up and down strategy: Test the scripts
― Monitor the performance
― Test the applications: Functional tests, Stress tests, Load tests, Negative
tests (insufficient disk, no network etc)
• Move to production
― Shop around for optimum resources
― Test and Move
― Watch for discounts (Holiday season? And migrate?)
