How, when, and why you should use a caching strategy in your applications
Generally, when developing an application, we focus on developing its functionalities and may neglect other important aspects such as security and performance. A data caching strategy within our application allows us to take care of the performance aspects within our application. In this section, we will answer the questions of why, when, and how to implement a caching strategy.
Why is having a cache strategy important?
Although some applications can work autonomously, without needing to integrate with other services, most applications need to obtain information either by accessing services or databases.
This is not a problem when our application generates small traffic against these services or databases, and it only faces latency problems when it's accessing a service that is very far in terms of location from our computing resources:
