As it was built using non-blocking I/O, it can serve more concurrent requests than a blocking server, such as Apache, which can be achieved through asynchronous events. When a function call blocks, Node.js will reply via a callback. The great foundation of Node.js has led to many libraries that allow you to build a scalable application.

Redis is another vital building block of scalable applications. While Redis is not Node.js-specific, it offers great support. It fills up the need of shared memory between web servers that scalable applications require. Redis also has bindings in some other frameworks, which will be covered in this book. This prevents us ...
