What do you understand by a high-load platform? How many RPS?

A high-load platform is a system capable of processing a very large volume of requests or operations per unit of time with minimal delays and high reliability.

Regarding RPS (requests per second), the threshold for high load depends on the context and infrastructure, but generally:

• Several thousand RPS is already considered a serious load for typical web applications.
• Tens and hundreds of thousands of RPS are characteristic of large services (e.g., social networks, search engines).
• Millions of RPS are for large-scale distributed systems and CDNs.

It's important not only the number of requests but also the complexity of processing, delay requirements, resilience to peak loads, and scalability of the architecture.
