There are a lot of contenders. Cloud Foundry is one of the many, you'll see others (Flynn, Deis, OpenShift, I always miss a zillion) mentioned in this discussion. I like Cloud Foundry because I work on it. It runs on AWS, Azure, GCP, OpenStack, vSphere, RackHD and others. If someone wrote a BOSH CPI for DigitalOcean it'd run there too without much fuss. Disclosure: I work for Pivotal, we donate the majority of engineering on Cloud Foundry.
