What is it?
Using Everything-as-Code by putting all infrastructure and configuration data into code, applications can be deployed in a repeatable and reliable fashion. Put it into action! Deploy code in one environment, and then re-deploy into another environment. Or destroy the first one and re-deploy :D
Practice on a cadence (1-3 weeks) in order to catch all the bugs! Keep repeating until all the bugs are caught! It gets easier each time, and everyone on the team should practice it for a shared understanding!
Why use it?
To build resiliency and reliability for the automation of code deployment, resulting in less downtime, and more throughput.
