If you're looking to improve the performance of your Laravel web application, then implementing a cache layer could be a good option. As a very high-level overview, using a cache allows data to be stored and then quickly retrieved. Common use cases include replacing slow or repetitive database queries, or even entire HTTP responses.
Although Laravel comes with a great, easy to use solution for server-side caching, there is still a lot to consider when implementing a cache layer in your application. What should be cached? How long should it be cached for? Where should we cache it?
