4. About Cloud Computing in general
● On-Demand delivery of IT resources
● Over the Internet
● With primarily Pay-As-You-Go pricing
● No need to buy, own and maintain physical data centers
Resources include but not limited to:
● Compute power
● Databases
● Storage
● Applications
● Networking services

5. Cloud Computing History

6. Google Cloud
Introduced in April 2008 with the App Engine, a platform for
developing and hosting web applications in Google-managed
data centers.

7. Benefits of Cloud Computing
Trade upfront expense for
variable expense
Benefit from massive
economies of scale
Stop guessing capacity
Increase speed and agility Focus on what matters Deploy globally in minutes

8. Cloud Strategy
Over 37% of cloud migrations fail. Brands like Twitter,
Pinterest and TSB, a UK based bank experienced failure
during their cloud migration implementation.
Key reason for failure was:
Not having a strong and clear cloud strategy before embarking on
the migration journey. [according to the CSA report]
“Good tactics can save even the worst strategy. Bad tactics will destroy even the best strategy.”
General George S. Patton Jr.

10. Cloud Migration Strategy
● Rehosting or "lift-and-shift"
● Replatforming, or "lift, tinker, and shift"
● Refactoring / Re-architecting
● Repurchasing
● Retaining
● Retiring
