A suite of Ansible playbooks for automated AWS provisioning

I’ve recently produced a series of articles aimed at startups, entrepreneurial solo developers, etc. wanting to take their first steps into Amazon Web Services (AWS) setups for app deployment:

I then wanted to move on from discussing manual setup via the GUI interface of the AWS web console, to DevOps-style command-line programmatic setup for automated provisioning of an AWS infrastructure for app deployment, i.e. infrastructure as code (IaC). I have therefore created a suite of Ansible playbooks to provision an entire AWS infrastructure with a Staging instance and an auto-scaled load-balanced Production environment, and to deploy a webapp thereon. The resulting set of Ansible AWS provisioning playbooks and associated files can be found in my GitHub repository, so go ahead and grab it from there if you want to try them out. Keep reading for information on how to set up and use the playbooks (and you can also refer to the README in the repo folder, which contains much of the same information).

With these playbooks, firstly the EC2 SSH key and Security Groups are created, then a Staging instance is provisioned, then the webapp is deployed on Staging from GitHub, then an image is taken from which to provision the Production environment. The Production environment is set up with auto-scaled EC2 instances running behind a load balancer. Finally, DNS entries are added for the Production and Staging environments.
