Usage of Go in VK's Infrastructure Tasks
summary
VK ports a push dispatcher from Node to Go and runs it on ~24 machines delivering ~9 billion pushes/day with delivery rising to ~90% using goroutines and channels and dynamic pools; Go static binaries simplify ops. A music-recognition engine and WebSocket streaming API are implemented in Go (about 50k lines of Go added to a 4M-line PHP codebase), ClickHouse reverse proxies aggregate logs from ~45k servers, and a Go-based live streaming/image/transcoding stack replaces brittle C/C++ components — all deployed and working.
