Are there negative sides to microservices?

Microservices have many advantages, but they also have disadvantages:

• Management complexity: a large number of services requires careful orchestration, monitoring, and logging.

• Network delays and errors: interaction between services occurs over the network, which can lead to delays and errors that are harder to debug.

• Increased infrastructure requirements: more resources are needed to run multiple services, as well as tools for deployment and scaling.

• Difficulties with transactions and consistency: distributed transactions are more complex to implement, often requiring eventual consistency.

• Increased testing complexity: integration testing becomes more difficult due to the multitude of interacting components.

• Version management and compatibility: it is necessary to monitor API compatibility between services, which complicates updates.

Thus, microservices require a more mature development and operation process, as well as additional tools for managing a distributed system.
