Overview of this book

Node.js is a modern development stack focused on providing an easy way to build scalable network software. Backed by a growing number of large companies and a rapidly increasing developer base, Node is revolutionizing the way that software is being built today. Powered by Google's V8 engine and built out of C++ modules, this is a JavaScript environment for the enterprise.Mastering Node.js will take the reader deep into this exciting development environment. Beginning with a comprehensive breakdown of its innovative non-blocking evented design, Node's structure is explained in detail, laying out how its blazingly fast I/O performance simplifies the creation of fast servers, scalable architectures, and responsive web applications.Mastering Node.js takes you through a concise yet thorough tour of Node's innovative evented non-blocking design, showing you how to build professional applications with the help of detailed examples.Learn how to integrate your applications with Facebook and Twitter, Amazon and Google, creating social apps and programs reaching thousands of collaborators on the cloud. See how the Express and Path frameworks make the creation of professional web applications painless. Set up one, two, or an entire server cluster with just a few lines of code, ready to scale as soon as you're ready to launch. Move data seamlessly between databases and file systems, between clients, and across network protocols, using a beautifully designed, consistent, and predictable set of tools.Mastering Node.js contains all of the examples and explanations you'll need to build applications in a short amount of time and at a low cost, running on a scale and speed that would have been nearly impossible just a few years ago.

Big data applications have placed significant responsibility on developers of network applications to prepare for scale. Node has offered help in creating a network-friendly application development environment that can easily connect to other devices on a network, such as cloud services and, in particular, other Node servers.

In this chapter we learned some good strategies for scaling Node servers, from analyzing CPU usage to communicating across processes. With our new knowledge of message queues and UDP we can build networks of Node servers scaling horizontally, letting us handle more and more traffic by simply replicating existing nodes. Having investigated load balancing and proxying with Node, we can confidently add capacity to our applications. When matched with the cloud services provided by AWS and Facebook, we are able to scale our data stores and user account management with ease and at low cost.

As our applications grow we will need to maintain continuous awareness of how...
