TIAD : Automating the aplication lifecycle
This document discusses automating the application lifecycle using infrastructure as code principles. It demonstrates building infrastructure like VPCs and databases automatically with CloudFormation templates. It then shows deploying application components like load balancers and servers from templates. It discusses updating applications by building new server images from code changes rather than modifying existing servers. This allows deploying updates instantly by replacing server instances. The talk concludes that automating infrastructure and deployments in this way allows integrating new applications or changes much faster.
