What are the best practices for server-side caching?

Server-side caching improves performance by storing frequently accessed data. Key practices include using appropriate cache expiration, choosing the right caching strategy (like in-memory or distributed caching), and monitoring cache performance.

Can you explain the difference between in-memory and distributed caching?

In-memory caching stores data in the server's RAM, providing fast access but limited by server capacity. Distributed caching spreads data across multiple servers, enhancing scalability and fault tolerance.

What tools can I use for server-side caching?

Popular tools include Redis, Memcached, and Varnish. Each has unique features suited for different caching needs.

How do I determine the right cache expiration time?

Cache expiration should balance freshness and performance. Analyze data access patterns and adjust based on how often data changes.
