By the end of the last chapter, we managed to wrap up and complete our ArcGIS web application using ArcGIS for Server as the backend server and JavaScript API as the client-side application. Esri has invested a lot in a new technology to completely migrate the ArcGIS technology to the web platform, which they call ArcGIS Online. With this technology, you can author your maps to your ArcGIS online account and consume it via various built-in template applications. You can also customize your own application to utilize an ArcGIS online map.

In this Appendix, we will learn how to create an ArcGIS online account, upload our Bestaurants data to create a map on our account, and then finally, we will use the ArcGIS JavaScript API to consume the online Bestaurants map.
