The BFF Pattern: Glue or Liability?

In this episode, we take a hard look at the Backend-for-Frontend (BFF) pattern: why it was introduced, where it actually helps, and where it starts to fall apart in real-world microservices architectures.

We explore the core problems BFFs were meant to solve—API orchestration, frontend-specific shaping, security boundaries—but also the unintended costs: duplication of business logic, latency introduced by over-network composition, and fragile coupling to backend services.

We’ll also dive into practical solutions:

✅When to use a BFF and when to consolidate

✅How caching can save or sink your BFF

✅Design tips for reducing orchestration overhead

✅Emerging approaches like multi-runtime co-location (Node + PHP, serverless + monoliths) that challenge the need for standalone BFFs entirelyIf you're scaling a frontend-heavy app or drowning in edge-layer glue code, this one’s for you.
