Microservices
An application split into many small services that are built and released separately, talking to each other over the network.
What it tells you about a developer
Microservices experience means the developer has worked with services that fail independently, which is distributed systems work. On a small team’s req the word sometimes describes an ambition rather than what exists today.
Microservices break a product into separate programs, each owned by a team and released on its own schedule. Teams stop waiting on each other, and the network between the services becomes a new source of failure. The pattern spread widely in the 2010s, and the field has since cooled on it for smaller companies, because the operational cost is real.
