Cloud Formation
-
Consider creating the following architecture
-
Options are
- AWS Console
- AWS CLI
-
Lets assume i preferred console and created the architure using UI.
-
Next day i got a request to recreate the same architecture, now what should be approach
-
Mostly automation and i have two possibilites
- Write a shell script/powershell script using AWS CLI
- Write a cloud formation template
-
Lets stick to shell scripts, problems here
- Difficult to change
- when the script runs it is not guranteed to get th same result
-
Cloud formation template is
- a json/yaml file
- It is IAC with idempotentance.
-
Cloudformation template is a json/yaml based declarative way of creating infrastructure
