Migrating Legacy Monoliths to Microservices

### Breaking the Monolith Legacy systems are the backbone of many enterprises, but they can be rigid and difficult to scale. Migrating to a microservices architecture is often the key to unlocking agility. #### The Strangler Fig Pattern One of the most effective strategies for migration is the Strangler Fig pattern. This involves gradually replacing specific functionalities of the monolith with new microservices, eventually "strangling" the old system. #### Key Challenges * **Data Consistency:** Managing distributed transactions. * **Observability:** Tracing requests across services. * **Complexity:** Managing deployment pipelines for hundreds of services. #### Benefits * **Scalability:** Scale individual components as needed. * **Resilience:** Failure in one service doesn't bring down the whole system. * **Speed:** Independent teams can deploy faster.
