  Cloud cost estimates for Terraform in pull requests💰📉 Shift FinOps Left!

  

  Project mention: Show HN: See the impact on your cloud costs as you code | news.ycombinator.com | 2024-08-13

  Hi, my name is Owen and I recently started working at Infracost (YC W21 batch) (https://infracost.io). Infracost shows engineers how much their code changes will cost on the cloud before it gets deployed. For example, when an engineer changes a cloud resource (like an AWS virtual machine), Infracost posts a comment in CI/CD telling them "This change is going to increase your costs by 25% next month from $500/m to $625/m".

  Previously, I was one of the founders of tfsec, the code security scanner; I quickly realised that identifying issues in your code (especially infrastructure code, i.e. Terraform) as soon as possible was the best defence. A lot of the principles of code scanning for security misconfigurations translate well to identifying cost impact. Many times, people are surprised by how cloud resources are priced and how expensive they can be. It is also really unfair that engineers are never given a ‘checkout screen’ when buying infrastructure, and then are blamed for breaking cloud budgets.

  I believe engineers should have access to key information about cloud costs at the time of writing the code. So, I spent some time and built an Infracost plugin for the IntelliJ family of IDEs (https://plugins.jetbrains.com/plugin/24761-infracost).

  With this plugin installed, as you develop your Terraform code, you will get the cost impact of your current project, and quickly see where the expensive resources are hiding in your code (just hit save & it will recalculate). Two main use cases I’m thinking of:

  - As you change resources, you can see the cost impact. For example, I increased the instance size from my Dev to Prod environment to handle the prod-sized workloads, and I can see the increase costs.

  Cost monitoring for Kubernetes workloads and cloud costs

  I believe for AWS, they use these ratios: https://github.com/opencost/opencost/blob/c2de805f66d0ba0e53...

  So in your example, 6 CPU + 16GiB is roughly 2x more than 2 CPU and 16GiB, so if that node cost say $6/hr, you'd expect it to be allocated $2 to the first and $4 to the second.

  They have these weights for various clouds here: https://github.com/opencost/opencost/tree/c2de805f66d0ba0e53...

  Project mention: Releasing my CLI FinOps tools and Terraform building blocks in the ONCE model | news.ycombinator.com | 2024-06-04

  - EBS Optimizer for GP3 converting EBS volumes to GP3, also available as OSS at https://github.com/LeanerCloud/EBS-Optimizer

  (I'm currently working on a few more, for example a NAT Gateway alternative and a tool to automate Savings plans purchases.)

  Over the last year I started to offer cost optimization as a service, mainly in order to get more ideas for such tools.

  Over multiple customer engagements I built almost a dozen CLI tools that can be used to optimize many of the AWS services at my customers.

  I also did a few DevOps engagements, out of which I developed a bunch of Terraform building blocks that can be used to create ECS Fargate or Lambda microservices with RDS Aurora for persistence, with automated CI/CD and other goodies included out of the box.

  My main FinOps CLI tool named Optimizer was evolved out of EBS Optimizer over multiple customer engagements, and now does automated conversion to GP3 for EC2 and RDS storage volumes, as well as rightsizing and conversion to Graviton for RDS, ElastiCache and OpenSearch, among other things.

  I recently started to offer Optimizer under the ONCE Source-Available license used by 37signals for Campfire, and I will gradually release all my CLI FinOps tools and Terraform building blocks as a bundle under the same license.

  Using this set of tools I was able to deliver some 70% cost optimizations in average at my services customers (over the supported resources), so if you're looking to optimize cloud costs and/or build serverless microservices on AWS, you may want to check this out.
