What methods do you use to reduce server load during high request volume?

To reduce server load during high request volumes, several approaches can be used:

• Caching: storing frequently requested data in memory or on disk to avoid repeated computations.
• Load balancing: distributing incoming requests among multiple servers for even resource utilization.
• Using CDN: for static content to reduce load on the main server.
• Query and database optimization: indexing, reducing the number of queries, using efficient queries.
• Asynchronous processing: performing heavy tasks in the background to avoid blocking the main request processing thread.

For example, Redis can be configured for caching API request results, and Nginx can be used as a load balancer among multiple application instances.
