You can make spaghetti from anything. A micro service implementation of that would be CQRS, where the services to write updates, backend process (eg, notifying the crew to buy appropriate food), and query existing records are separated. You might even have it further divided, eg the “prepare cruise” backend calls out to several APIs, eg one related to filing the sailing plans, one related to ensuring maintenance signs off, and one related to logistics.
