Stateless apps in one, stateful apps in the other

It happens to be the case that CF — because it’s an app platform and wants to let the user focus on their code — provides a way to convert code in to containers inside the platform without having to start messing around with Dockerfiles and the like. And this functionality even does some cool things for you like keeping your container OS automatically patched so you don’t have to build CI pipelines to monitor your base images and rebuild stuff.

That’s why I love Cloud Foundry’s Application Runtime. Of course, because of these constraints — the constraints that are why I love it — the App Runtime can’t possibly work for complex stateful services: the whole point is for it not to. And that’s why it’s fantastic that there’s now a Container Runtime (which I wish we’d called a Stateful Services Runtime because that’s how I think of it).
