Service Mesh Resolver Cache

Service Mesh Resolver Cache is a networking performance layer that stores DNS answers for reuse until they expire for east-west service communication. It uses TTL rules, cache keys, and invalidation so teams can reduce lookup latency while keeping evidence, reliability, and public-safe operational boundaries clear.

“The network engineering team used Service Mesh Resolver Cache when a service called another service, so the team could reduce lookup latency before traffic crossed a service boundary.”
