Migration of a monolithic application to microservices using DDD

The company plans to transition from a monolithic architecture to a microservices architecture. It is necessary to formalize the process of system decomposition using the Domain‑Driven Design approach, covering the following aspects:

• Approach to dividing the business domain into domains and subdomains;
• Identification and formalization of bounded contexts;
• Definition of aggregates and their root entities;
• Designing a domain events model for asynchronous service interaction;
• Ensuring data consistency and integrity between individual microservices;
• Addressing issues related to distributed transactions;
• Testing strategy focusing on integration tests;
• Data migration from the monolith to new microservices;
• Architectural solutions considering scalability, domain complexity, and the need for system evolution.
