One of ArcGIS Pro's big strengths is its integration with ArcGIS Online and Portal for ArcGIS. This allows you to easily publish data and maps to the web that can then be accessed by others even if they do not have GIS software installed.
ArcGIS Online is Esri's cloud-based Software-as-a-Service (SaaS) solution. This allows you and others both in and outside your organization to access data, maps, and applications via the internet. This makes it much easier to share your GIS with others because they can access the content you share with them via a normal web browser.
In this section, you will learn how you can publish a map that you create in ArcGIS Pro to ArcGIS Online so that it can be accessed by others through the web browser.
