I ran our CI on fargate at my last job. It was a mess. The time from api request for an instance to it being ready to handle a job was minutes. It was about 50x slower than running on a mid range laptop that I occasionally used for development, and in order to work around that we kept hot EBS volumes of caches around (which cost $$$$ and a decent amount of developer time). Just before I left I was investigating using hetzner instead - our compute bill would have been about 15% cheaper, we would have had no cache storage costs (which was about 5x our compute costs), and the builds would have finished before fargate had processed the request. Our numbers were small fry, but we spent more on that CI system than we did on every other part of our infra combined.
