Sure! There are several types, including in-memory caches, disk caches, and distributed caches. Each serves different use cases.

What are the benefits of using caching layers?

The main benefits include faster data retrieval, reduced load on databases, and improved application performance.

Are there any downsides to using caching layers?

Yes, potential downsides include cache invalidation issues, increased complexity, and the risk of serving stale data.

How do I implement a caching layer in my application?

You can implement a caching layer by choosing a caching solution like Redis or Memcached, then integrating it into your application logic.
