What is The Cloud?
 
….A Commodity or Utility
 
Once upon a time… If you needed electricity, you had to produce it yourself.
 
 
Then a New Idea came out …
 
…generate a LOT of electricity Centrally and have everybody tap from it
 
 
 
What is Cloud Computing?
 
…The evolution of Hosting

Why Cloud Computing?
 
  • Outsource functions to external services
  • The Cloud is PaaS – Platform as a Service
  • Expose your on-premises services (workflows) ‘in the cloud’ for others to consume
  • Advantages – No More IT Headache; Scale; Reach; Pay as you use
