The Evolution of Application Architecture and the Rise of Lightweight Orchestration

2025-03-22

From the three-tier architecture of the 90s to today's microservice-driven world, application architecture has undergone a dramatic transformation. To coordinate operations in distributed backends, the orchestration tier emerged. However, existing DIY solutions are complex and hard to maintain, while dedicated orchestration systems introduce their own complexities. This article presents a new approach: integrating orchestration functionality into a lightweight library and using a database to persist execution state. This eliminates the separate orchestration tier, simplifying development, testing, and debugging, ultimately leading to more reliable and efficient application architectures.

Lightweight Durable Execution: The DBOS Transact Open-Source Library

2025-02-03

Traditional durable execution relies on external orchestrators like AWS Step Functions, adding complexity to development and deployment. DBOS Transact is a lightweight open-source library that integrates durable execution into the program itself, eliminating the need for external orchestrators. It achieves durable execution by persisting the program's execution state in a Postgres database, allowing automatic recovery to the point of interruption even if the program crashes or restarts. DBOS Transact also provides additional features such as durable sleep, durable messaging, and durable queues, further simplifying the development of reliable, stateful programs.
