CloudFormation snippet to create a VPC to be used for lambda functions. Qualities of the VPC:

  • 4 subnets: 2 public, 2 private (lambda functions should be attached to the private ones).
  • 2 Elastic IPs that can be used to identify traffic coming from lambda functions (e.g. for firewall holes).
  • Security group that can be used for lambda functions.

Notes:

  • uses regions us-east-1a, us-east-1b
  • uses ip block of 10.15.0.0/16 for VPC

Blue-Green AWS Auto Scaling Deployments with Terraform

A quick note on how I'm currently handling Blue/Green or A/B deployments with Terraform and AWS EC2 Auto Scaling.

In my particular use case, I want to be able to inspect an AMI deployment manually before disabling the previous deployment.

Hopefully someone finds this useful, and if you have and feedback please leave a comment or email me.

Overview

I build my AMI's using Packer and Ansible.
