A Practical Look at Architectural Challenges and Opportunities in the Cloud

Code: How? Architecture: What/When? Business: Why?

1 gallon of fuel -> ¼ ton of ‘freight’ ; 20 miles 1 gallon of fuel -> 1 ton of freight ; 436 miles but Can mostly go from A to B Leaves 2x day at 9.12am and 11.14pm but Can goes anywhere there is a road Ready to go anytime Economy of Scale Low High Control High Low

Economy of Scale Low High Control High Low Build vs. Buy

Economy of Scale Low High Control High Low On premises vs. in the cloud

Application runs on-premises Buy my own hardware, and manage my own data center Application runs at a hoster Co-location or Managed servers Application runs using cloud services “ cloud fabric” (elastic, infini-scale) Economy of Scale Low High Control High Low

“ Packaged” Application An application that I buy “off the shelf” and run myself Self Hosted “Home Built” An application that I develop and run myself Hosted “ Home Built” An application that I develop myself, but run at a hoster Hosted “ Packaged” An application that I buy “off the shelf” and then run at a hoster Cloud Platform An application that I develop myself, but run in the cloud “ Software as a Service” A hosted application that I buy from a vendor On premises vs. Cloud On premises Cloud Build vs. Buy Build Buy

Hosted version of what you have been using so far
Requires few changes if any to what you know and do
New capabilities
New cost structure
Requires embracing a specific app model
