->* Our example utilizes infrastructure as code and includes a simple pipeline that will build and deploy within an individual account and to an individual environment. However the nature of this example means it can be deployed many times it's possible. You can for example deploy a staging pipeline that would watch a development branch and deploy and changes to the Staging application stack.
