What are the differences between distributed cache and local cache?

What are the differences between distributed cache and local cache?

Distributed cache is shared across multiple servers, while local cache is stored on a single server. Local cache is faster for individual requests, but distributed cache scales better for large applications.

Can you give me examples of when to use each?

Use local cache for applications with low traffic or single-server setups. Use distributed cache for high-traffic applications needing scalability.

What are the performance implications of each?

Local cache generally offers lower latency since data is stored closer to the application. Distributed cache may introduce some latency due to network calls but can handle larger datasets.

Are there any specific technologies you recommend for each?

For local caching, consider using in-memory solutions like Redis or Memcached. For distributed caching, Redis Cluster or Apache Ignite are popular choices.
