The service now knows it’s being cached. It has a cache key. It has an invalidation call in the delete method. It has become a caching service with a thin layer of business logic underneath. That bothered me. The application layer is supposed to contain orchestration and business use cases — not decide whether a response came from memory or a database.https://eunus.dev/blog/do-you-actually-need-microservices-or-nosql-to-build-a-fast-system-heres-how-to-know./Wed, 10 Jun 2026 00:00:00 +0600https://eunus.dev/blog/do-you-actually-need-microservices-or-nosql-to-build-a-fast-system-heres-how-to-know./If you’re planning to build a system and a developer or a vendor has already told you it needs to be microservices or NoSQL to be fast, this is worth reading before you sign off on that. I recently had the chance to sit in on a session on agentic AI coding, built around a small ecommerce microservice MVP repo, the kind of session my workplace invests in so the team keeps learning.
