Simple Abstractions for the Challenge of Complexity
summary
Diego is a layered runtime that turns Cloud Foundry into an independently deployable BOSH release and isolates components so each can be tested and swapped (Garden backends, ETCD/MySQL for BBS) without changing others. It models work as desired LRPs and one‑off tasks, compiles those into composable actions (download, run) and uses a CC‑bridge plus NSYNC/TPS closed feedback loops to keep eventual consistency; GA Diego (2015) adds zero‑downtime deploys and container/runtime agnosticism.
