What disadvantages can arise when migrating a system from monolithic architecture to microservices?

When migrating from a monolith to microservices, the following disadvantages may arise:

• Management complexity — the number of services increases, requiring new tools for orchestration, monitoring, and logging.
• Data consistency issues — data is distributed across different services, complicating the maintenance of integrity and transactions.
• Increased infrastructure requirements — network setup, load balancers, and service discovery systems need to be configured.
• Increased latency — interactions between services occur over the network, which can slow down responses.
• Testing difficulties — integration testing becomes more labor-intensive due to the distributed nature of the system.
• Security issues — secure interaction between services must be ensured.

All these aspects require careful planning and the implementation of additional tools and practices.
