This post isn’t so much about how I consolidated a lot of ALBs, but more about how I saved ~USD$3,300 a year by doing this consolidation.

Why Infrastructure as Code (IaC) is important

Infrastructure as Code or IaC is becoming a staple for configuring, deploying and maintaining infrastructure and service configuration in the cloud. Both of the large Hyperscalers, AWS and Azure support their own version of IaC. AWS has CloudFormation, and Azure has ARM (Azure Resource Manager). Then there is the ever popular open source Terraform from Hashicorp. AWS released CloudFormation on 25th February 2011, Azure released Azure Resource Manager in April 2014 around the same time that Hashicorp started hacking on Terraform. Read more
