How is distributed caching implemented?

What is distributed caching and why is it important?

Distributed caching is a method of storing data across multiple servers to improve access speed and reliability. It's important because it reduces latency and increases the scalability of applications.

How do you implement distributed caching in a web application?

To implement distributed caching, you can use tools like Redis or Memcached. You'll need to set up a caching layer that interacts with your database and application logic.

What are the common challenges faced during implementation?

Common challenges include cache consistency, data expiration, and handling cache misses. It's crucial to design a strategy to manage these issues effectively.

Can you give an example of a use case for distributed caching?

Sure! A common use case is in e-commerce websites where product information is frequently accessed. Caching this data reduces database load and speeds up page load times.
