What is Distributed Caching?

Distributed caching is a system architecture where data is stored across multiple networked servers or nodes to improve performance, scalability, and availability. It works by temporarily storing frequently accessed data closer to the application or user, reducing the need to repeatedly retrieve it from the primary data source (e.g., a database). This approach reduces latency, improves response times, and lowers the load on the underlying data store. Distributed caches are commonly used in web applications, content delivery networks (CDNs), and microservice architectures.
