Saga Pattern

What is a saga pattern?

The saga pattern is a design pattern used to manage distributed transactions in a microservices architecture. It helps ensure that in a system with multiple services, a sequence of operations is either fully completed or, if any operation fails, compensatory actions are taken to revert the system to a consistent state.

Analogy

The saga pattern can be thought of as a theatrical play with multiple acts, where each act represents a service or operation in a complex transaction within a distributed system. AWS Step Functions or other orchestration tools serve as the director, coordinating the execution and managing the flow of the performance.
