What do you see as the specifics of high-load systems? How do they differ from medium-load systems in terms of design?

High-load systems differ from medium-load systems primarily in data processing scale and the number of simultaneous requests. Design specifics:

• Scalability: architecture should easily scale horizontally (adding servers) and vertically.
• Fault tolerance: the system should continue to operate in case of individual component failures.
• Load balancing: distributing requests to prevent overloads.
• Performance optimization: using caching, asynchronous processing, minimizing locks.
• Monitoring and alerting: for quick detection and response to issues.

In medium-load systems, these requirements are less critical, and simpler architectural solutions can be used with less focus on scalability and fault tolerance.
