Server-Side Caching
Server-side caching is a performance optimization technique where frequently accessed data or computed results are stored temporarily on the server to reduce redundant processing and database queries. It involves caching responses, database query results, or application data in memory (e.g., using Redis or Memcached) or on disk to serve subsequent requests faster. This reduces server load, improves response times, and enhances scalability for web applications and APIs.
Developers should implement server-side caching when building high-traffic applications, APIs, or services where performance and scalability are critical, such as e-commerce sites, content management systems, or real-time data platforms. It is essential for reducing database load during peak usage, minimizing latency for repeated requests, and handling concurrent users efficiently, especially in microservices or distributed architectures.
