Caching

Caching is the process of storing frequently accessed data in a temporary storage location, called a cache, in order to quickly retrieve it without the need to query the original data source. This can improve the performance of an application by reducing the number of times a data source must be accessed.

There are several caching strategies:

  • Refresh Ahead
  • Write-Behind
  • Write-through
  • Cache Aside

Also, you can have the cache in several places, examples include:

  • Client Caching
  • CDN Caching
  • Web Server Caching
  • Database Caching
  • Application Caching
