I a quest to optimize the performance of my WordPress powered site, I thought I’d give Redis Cache a go. Redis Cache has become the industry default when it comes to caching in a key-value style. Azure has a Redis Cache offering which you can use to enhance the performance of any app. If you’re not familiar with caching: it’s a mechanism to eliminate timely data retrieval actions. Caching can be implemented several different places: you web browser uses caching so that it does not have to retrieve all files on every load. Redis Cache is usually more targeted towards scenario’s like database connections. Instead of getting items from a database table, which usually is relatively slow, you can get them from the cache instead.
