Events are the wrong abstraction: Rethinking distributed systems

What this post added

This post argues that Event-Driven Architecture (EDA) is an outdated and overly complex abstraction for distributed systems, drawing parallels to the geocentric model of the solar system. It details common pitfalls of EDA, including lack of APIs, tight coupling, scattered logic, poor debuggability, ad-hoc state machines, increased latency, race conditions, and system upgradability challenges. The post then presents Durable Execution, as exemplified by Temporal, as a superior abstraction that centralizes business logic, manages state consistently, handles failures gracefully, and allows for flexible process design, ultimately leading to more reliable and maintainable distributed systems.
