Estrategias para transformar aplicaciones monolíticas a aplicaciones distribuidas altamente desacopladas

Abstract

In the field of software development, monolithic architectures are commonly found due to their initial simplicity and ease of implementation. However, as software evolves and grows in complexity, the challenges associated with this architecture often outweigh its advantages, necessitating strategic decisions to guide its evolution. Transforming a monolithic architecture into more decoupled styles presents both technical and business challenges that must be addressed comprehensively. This work tackles the evolution process through the implementation and analysis of several proof-of-concept cases. In the first case, a monolithic application is transformed into an Event-Driven Architecture (EDA), enabling service decoupling and improved scalability. In the second case, an approach based on Command Query Responsibility Segregation (CQRS) is implemented alongside Event Sourcing, optimizing the separation of concerns and enhancing performance in high-concurrency environments. Finally, in the third case, the monolithic application is decomposed following microservices architecture principles, facilitating its scalability, maintainability, and resilience.
