What are the benefits of using Caching (Redis/Memcached)
cachingredisdatabaseperformance
In high-traffic applications, the database often becomes the bottleneck. Caching is one of the most effective strategies to scale reads and reduce latency.
Why Cache?
In this article, I explore the fundamental benefits of introducing a caching layer like Redis or Memcached:
- Reduced Latency: Serving data from memory (RAM) is orders of magnitude faster than reading from disk.
- Throughput Scaling: Handling thousands of requests per second without upgrading the primary database.
- Cost Efficiency: Reducing read operations on expensive database instances (e.g., AWS RDS).
I also touch on the differences between Redis and Memcached and when to choose which.
