Caching has been around for decades, as accessing data quickly and efficiently is critical when building application services. Caching is a mandatory requirement for building scalable microservice applications. Therefore, we will be reviewing three approaches to caching in modern cloud-native applications.
In many use cases, the cache is a relatively small data storage medium using fast and expensive technology. The primary benefit of using a cache is to reduce the time it takes to access frequently queried data on slower and cheaper large data stores. In modern applications, there is a multitude of storage methods of caching data, but let’s briefly cover the two most popular approaches:
