ArcGIS Online is a collaborative, cloud-based platform that allows members of an organization to use, create, and share maps, apps, and data, including authoritative basemaps published by Esri. Through ArcGIS Online, you get access to Esri’s secure cloud, where you can manage, create, store, and access data as published web layers, and because ArcGIS Online is an integral part of the ArcGIS system, you can use it to extend the capabilities of ArcGIS for Desktop, ArcGIS for Server, ArcGIS apps, and ArcGIS Web APIs and ArcGIS Runtime SDKs.
With ArcGIS Online, you can use and create maps, access ready-to-use layers and tools, publish data as web layers, collaborate and share, access maps from any device, make maps with your Microsoft Excel data, customize the ArcGIS Online website, and view status reports. You can also use ArcGIS Online as a platform to build custom location-based apps. Watch a short video.
ArcGIS includes interactive maps that allows your whole organization to explore, understand, and measure your geographic data. Access ready-to-use maps and enrich them with your own data to reveal patterns, answers, and relationships about your community and the world. Use the analysis tools included in the ArcGIS.com map viewer to reveal new patterns, find suitable locations, GeoEnich your data, find out what's nearby, and summarize your data.Watch a short video.
ArcGIS Online includes everything you need to create maps and create apps. Through the ArcGIS.com map viewer, you can access a gallery of basemaps to get you started and tools for adding your own data or layers. You can add shapefiles, spreadsheet data, KML files, OGC WMS and WMTS services, tile layers, geoRSS files, and GPS files and create mashups with data and maps shared by others. You also have access to easy-to-use tools for creating apps that you can publish to ArcGIS Online.Watch a short video
Enable interaction with your organizational data by sharing content related to a common activity. You can set up groups that are private and by invitation only, or public groups that are open to everyone. You can also share maps by embedding them in web pages, on blogs, in web apps, and through social media. ArcGIS Online includes a number of ready-to-use and configurable web app templates with different layouts that you can choose from. With just a few steps and no programming, you can publish a web app that features a dynamic map that anyone can access through a browser. Watch a short video.
You can publish your features and map tiles as web layers on ArcGIS Online. This frees up your internal resources, since these web layers are hosted in Esri’s cloud and scale dynamically as demand goes up or down. You can add your layers to web, desktop, and mobile apps and allow others to use them as well. You can publish your data directly from ArcGIS for Desktop or the ArcGIS Online website without needing to install your own server, and share them with others inside your organization who can add map layers or geoprocessing tools to their own maps and apps.

ArcGIS Online includes tools and settings that allow the administrator of the organization to not only customize the home page but also manage the organization as a whole. This includes configuring the website, inviting users and determining their access role, managing content and groups, and setting the security policy. Watch a short video.
As a developer, you can access the ArcGIS Online APIs and ArcGIS Runtime SDKs to build location-based solutions that include directions, advanced analysis, maps, geocoding, and more.
You can access ArcGIS Online through web browsers, mobile devices, and desktop map viewers, as well as directly through other components of the ArcGIS system, for example, the web APIs and ArcGIS for Desktop. By joining an organization and logging in with your organizational account, you see the organization's customized view of the website and have access to the organization's authoritative data and other geospatial content that you can use to create maps and apps. With your organizational account, you can also share your work with other members of your organization, participate in groups, and save your work.
If an organization has enabled anonymous access to their site, you can access any resources they have shared with the general public without signing in. For example, they may have embedded a group of maps and apps they authored in ArcGIS Online and into their own website and shared those resources with the general public.
A public account is another way to access ArcGIS Online. These accounts are not associated with an organization and offer a limited set of functionality. A public account allows you to use and create maps and share your maps and apps with others. Public accounts are for noncommercial use only.
