Design Microservices Architecture with Patterns and Principles - What Is Caching?

Caching is a technique to enhance system performance by storing frequently accessed data in memory, reducing the need for costly operations like database queries. It boosts performance, scalability, and availability, especially in microservices, by lowering latency and handling increased requests efficiently. Caching is particularly effective for read-heavy applications with infrequent data changes, such as e-commerce catalogs. It also helps avoid recalculations by allowing data sharing across applications, thus improving overall system efficiency.
