As an analyst, how would you describe the architectures you have encountered?

Architectures I have encountered can be characterized by several key aspects:

• Monolithic architecture: all components of the application are tightly coupled and deployed as a single unit. Advantages — simplicity of development and deployment, disadvantages — difficulty in scaling and maintenance.

• Microservices architecture: the application is divided into independent services that interact via APIs. This increases scalability, flexibility, and allows different teams to work in parallel, but requires complex orchestration and monitoring.

• Service-Oriented Architecture (SOA): similar to microservices but with larger, often centrally managed services.

• Event-driven architecture: components interact through events, which ensures asynchrony and loose coupling.

• Client-Server architecture: a classic model with separation into client and server parts.

When analyzing architecture, it is important to consider requirements for scalability, fault tolerance, development speed, support, and security. It is also crucial to understand how data is transmitted and processed, what protocols and technologies are used, and how integration between components is ensured.
