ArcGIS Online is an online, collaborative web GIS that allows you to use, create, and share maps, scenes, apps, layers, analytics, and data. You get access to Living Atlas of the World, apps, and Esri’s secure cloud, where you can add items and publish web layers.
Because ArcGIS Online is an integral part of the ArcGIS system, you can use it to extend the capabilities of ArcGIS Desktop, ArcGIS Enterprise, ArcGIS Web APIs, and ArcGIS Runtime SDKs.
ArcGIS Enterprise, the next evolution of the ArcGIS Server product line, is a full-featured mapping and analytics platform. It includes a powerful GIS web services server plus dedicated Web GIS infrastructure for organizing and sharing your work in order to make maps, geographic information, and analyses available on any device, anywhere, at any time.
