Summary

Migrating from a monolithic architecture to microservices is a complex process that offers benefits like scalability and resilience but requires careful planning to avoid potential pitfalls. This transformation demands not only technical expertise but also a clear understanding of the challenges, such as tightly coupled components and shared data models within the monolith. Successful migration involves thorough preparation, including assessing the suitability of the monolith for decomposition, building microservices capabilities, and defining service boundaries using domain-driven design principles. Incremental migration patterns like the strangler fig, parallel run, and branch by abstraction enable gradual service extraction with minimal disruption. Data migration strategies focus on transitioning from a shared database to service-specific data stores while managing data consistency and referential integrity. Organizational changes, including team restructuring and building a microservices culture, are crucial alongside technical shifts. Continuous Integration and Continuous Delivery (CI/CD) practices play a pivotal role in maintaining business continuity and achieving the business objectives of improved delivery speed, scalability, and resilience throughout the migration.
