What are the disadvantages of microservices architecture?

Disadvantages of microservices architecture:

• Management complexity: a large number of services requires advanced tools for orchestration, monitoring, and logging.
• Increased infrastructure requirements: network setup, load balancers, and service discovery systems need to be configured.
• Transaction difficulties: distributed transactions are more complex to implement than in monolithic systems.
• Communication delays: network interactions between services add latency and can lead to errors.
• Debugging and testing challenges: testing interactions between services is necessary, complicating the process.

Example: when developing a large online store, microservices allow dividing catalogs, orders, and payments, but require reliable communication and monitoring setup to avoid failures.
