I replaced my GitHub runners with Lambda MicroVMs, and maybe you should too

This article explores using AWS Lambda MicroVMs as GitHub Actions runners, highlighting benefits like customizability, pre-warming environments, and reduced network latency compared to default hosted runners. The author details the infrastructure setup (API Gateway, Lambda functions, SQS queues) and shares a CDK project for implementation. Key advantages include faster startup times and the ability to run in your own AWS account, while the downside is maintaining your own infrastructure. The article compares Lambda MicroVMs to AWS CodeBuild, noting MicroVMs are a better fit for GitHub runners due to snapshot-based booting and full OS support. It is a technical guide relevant to DevOps, cloud computing, and CI/CD optimization.
