Revolutionising Retail with Go
summary
Sainsbury’s claims go enables faster, smaller microservices that scale across 1,300 stores and 15–25 million daily transactions while the bank handles 236 million transactions a year. Architecture is cloud‑first on AWS, using Go for static‑linked binaries, protocol buffers + RPC internally and JSON + WebSockets at the edge. Example: a stock service updates inventory, publishes events to Rabbit, a stock API consumes the queue and pushes to sockets; repos mention micro, Cassandra and console; example handler is ~90 lines of Go.
