Declare, verify and execute microservices-based process flows
summary
ING builds and runs an open-source Scala library called Baker that declares orchestration as an internal DSL (recipes of interactions, ingredients and sensor events), generates visual graphs from code, and executes flows via a RESTful, event-driven runtime. It persists state in Cassandra, encrypts data, replays event journals for upgrades, supports short and long running flows, enforces firing limits for idempotency, and already sees adoption across 12 teams; real production processes span dozens of steps and the system runs successfully.
