This article analyses the ambiguous concepts of BFF in microservice architectures, distinguishing between “fat” BFFs that handle extensive orchestration and “skinny” BFFs that act mainly as transparent gateways, and discusses their responsibilities, advantages, drawbacks, and suitable scenarios.
The article explains the challenges of distributed transactions in microservices, introduces the Saga pattern as a solution, compares choreography and orchestration implementations, and outlines their benefits, drawbacks, and rollback mechanisms using an e‑commerce order processing example.
The article explains how the Saga pattern—using either choreography or orchestration—enables reliable distributed transactions across microservices by coordinating local ACID operations, handling compensating actions, and addressing the challenges of consistency, rollback, and scalability.
The article explains why traditional two‑phase commit fails in microservice architectures, introduces the Saga pattern as a solution, compares choreography and orchestration implementations, illustrates a step‑by‑step e‑commerce example, and discusses rollback handling, benefits, and drawbacks.
