What approaches are used to reduce the complexity of the system architecture in order to improve its resilience?

The following approaches are used to reduce system architecture complexity and improve its stability:

• Modularity and responsibility separation: dividing the system into independent components that can be developed, tested, and scaled separately.
• Use of microservices: each service is responsible for its part of the functionality, which simplifies support and error isolation.
• Application of design patterns: for example, the "Circuit Breaker" pattern to prevent cascading failures.
• Automation of testing and deployment: allows for quick detection and correction of errors.
• Monitoring and logging: timely detection of problems and analysis of system behavior.

These approaches help make the system more predictable and resilient to errors, as well as simplify its maintenance.
