In the previous chapters, we discussed the different layers of the web application technology stack. One of these layers was the middleware layer, which plays an important role in coordinating all the other layers of our application. In order for our application to be robust and available, we must ensure that we use the right technology for the job. Node.js has proved to be a great fit for our use case. Its asynchronous nature matches our requirements of quick and uninterrupted communication between the different layers of our stack.
