The document discusses the evolution of cloud computing from personal computers to large scale data centers and multi-tenant clouds. It describes how virtualization, multi-core computing, and distributed systems allow maximizing utilization of computing resources. Cloud computing provides scalable, on-demand access to computing and storage resources on a pay-as-you-go basis. While cloud computing provides benefits like flexibility and cost savings, issues around security, reliability, and lock-in still need to be addressed. The vision is for interconnected clouds that can dynamically migrate workloads.

Cloud Computing - Examples
Salesforce.com – entire sales force of 20,000 have been
totally dependent on SFDC for over 3 years
Amazon’s EC2 and S3 services to convert & store 11m
articles into PDF form (generating 5.5TB data) in 24 hours
An application on Facebook, went from 25K to 250K users in
3 days by launching 4000+ Amazon compute instances to
meet demand
