rapid application deployment with play framework
TRANSCRIPT
Jan-2015
Why Play is great for RAD
A pattern for rapid deployment via Play amp AWS
Seamless Remote testing via Play
Hot code reloading
Swagger plugin
Junit built-in
Great for most environments Dev Integration QA
Very nice for production Just a bit slower to launch
Less secure
But can be optimized to both
The Concept ldquoStatelessrdquo machine image
No code no credentials no data
ldquoDependency Injectionrdquo of the environment parameters
Init script
Run app
Ideal for AWS - Play - Git AMI
