Have you had experience splitting a monolith into microservices?

Yes, I have experience splitting a monolithic application into microservices. This process usually begins with analyzing the current architecture and identifying business domains that can be isolated. Then, separate services are created with clearly defined APIs and databases, which helps improve scalability and simplify maintenance.

Important points during such a transition:

• Gradual refactoring to avoid disrupting the system.
• Organizing communication between services (e.g., via REST or messaging).
• Ensuring data integrity and transactions.
• Setting up CI/CD for each microservice.

Example: from a monolith that handled orders, users, and payments, three microservices were separated — User Service, Order Service, and Payment Service, each with its own database and API.
