In a number of cases it is simpler and safer to start with a monolith. ### 1. **Small project or startup** When the product is still taking shape, requirements keep changing, and the team is small, microservices only add complexity. A monolith is faster to launch and easier to maintain. ### 2. **No DevOps infrastructure** Without CI/CD, containerization, and monitoring, managing many services by hand is impossible. Microservices without automation quickly turn into chaos. ### 3. **Small team** If there are few developers, splitting the system creates more communication and technical barriers than benefits. ### 4. **High requirements for data consistency** When business processes require strict transactions (for example, banking operations), distributed services complicate implementation and raise the risk of errors. ### 5. **No clear domain boundaries (bounded contexts)** If business areas are not separated, services start overlapping and depending on each other - this is no longer microservices, but a "sawn-apart monolith". **Summary:** > Microservices are justified at large scale, with mature processes and a clear domain structure. > In the early stages or with small teams, it is better to start with a simple monolith and split out services gradually.For the reviewerNote to the moderator (optional)Visible only to the moderator.
