The document discusses Node.js development in the cloud with Azure. It provides an overview of deploying Node.js applications to Azure Web Sites and infrastructure as a service (IaaS). It also demonstrates using Socket.IO with Node.js for real-time web applications and deploying a sample conference scheduling application to Azure that uses CouchDB for data storage.

JavaScript on server-side and client-side Event loop with a stack Node.JS serves requests in an event loop Large number of simultaneous requests. Avoids Context Switching Waiting for I/O or Synchronization operation to complete. Node attaches JS callbacks to I/O requests The “event driven” part When the original IO is completed, a callback to the server completes the request.
