Two-Phase Commit vs Saga Visualizer

Compare classic 2PC (prepare → commit) with a saga (local transactions + compensations) when a step fails.

Two-Phase Commit vs Saga

Step a multi-service booking through 2PC or a saga, then inject a failure and compare blocking commit vs compensation.

    Services: Inventory → Payment → Shipping. 2PC uses prepare/commit; saga runs local commits then compensates on failure.

    When to use which

    • 2PC: strong atomicity across few participants, blocking risk
    • Saga: long-running business flows, eventual consistency via compensations
