I like Azure in general, but Function cold start times are really awful. I regularly see start up times exceeding 10s for small, dotnet based functions. One is an auth endpoint for a self-hosted Docker registry, and the Docker CLI often times out when logging in if there is a cold start. I'm planning on moving these functions to Docker containers hosted in a VM. I have other issues with Functions too. If you enable client certificates, the portal UI becomes pretty useless, with lots of stuff inaccessible. I have one such endpoint in production just now, and it's even worse than that, as every now and then it just... stops working until I manually restart it. Nothing useful in the logs either.
