**The modern way to run GitHub Actions** RunsOn is the only platform to come with fully integrated solutions for fast, unlimited caches, including docker layers. And no limit on concurrency! The RunsOn server is deployed in your AWS account and runs on a $1.5/month AWS AppRunner container. It receives workflow events from GitHub Action, and launches ephemeral EC2 instances to fulfill the workflow job requirements. No dangling EC2 instances, unused capacity, docker-in-docker, or kubernetes cluster to manage (see architecture). It can be deployed in many AWS regions, and takes advantage of multiple availability zones to make sure it will always find a spot instance, with the least probability of being interrupted. In case no spot instance is available, it automatically switches to on-demand pricing to ensure that the job is scheduled (still 5x cheaper than GitHub).
