All of the topics that we’ve covered in this chapter have directly or indirectly been written to support applications. These functions and decorators are meant to help you start using Redis as a way of supporting different parts of your application over time. Logging, counters, and statistics are there to offer direct insight into how your application is performing. IP-to-location lookup can tell you where your consumers are located. And storing service discovery and configuration can save a lot of effort because of not needing to manually handle connections.
Now that we have a solid foundation for supporting applications in Redis, chapter 6 will continue down this path to functions that can be used as building blocks of your application.
