Anatomy of a BlueMix App

When you start out to create a cloud-based app it helps to understand the environment that it will run including the components that are external to it as well as the framework and runtime components that are integral to it.

An app runs both on the device (client) and in the cloud (server) and invokes services on both platforms.

Much of the logic that you build into an app is in the form of JavaScript.  On the server this might be application logic in the form of JavaScript running in the node.js runtime.

On the client side the JavaScript might be Dynamic HTML client-side scripting running in a browser or a mobile app.

JavaScript developers typically use standardized JavaScript code written by other developers in the form of libraries such as jQuery (on the client).
