Enterprise Java Can Do Games Too!
summary
Claim: Enterprise Java can host robust multiplayer back ends using Jakarta EE & MicroProfile and common tools rather than game engines. Concrete choices mapped to needs include WebSockets for stateful duplex (used by a paying customer), gRPC for structured streaming, raw UDP or datagram sockets for low latency, REST for leaderboards, and distributed caches like Redis Hazlecast Infinispan for in memory game state. Architecture uses virtual threads, short lock windows to resolve concurrent actions, a ticked game loop, and NoSQL persistence for evolving game data.
