ArcGIS Web Adaptor is a required components of Portal for ArcGIS which allows you to integrate your portal with your existing web server and your organization's security mechanisms. You cannot deploy Portal for ArcGIS in your organization without ArcGIS Web Adaptor. For ArcGIS Server, AArcGIS Web Adaptor integrates with your existing server.
Benefits of ArcGIS Web Adaptor
ArcGIS Web Adaptor provides the following benefits:
Allows you to integrate Portal for ArcGIS with your organization's existing web server. By including a web server in your site, you gain the ability to host web applications that use your GIS services.
Allows you to use your organization's identity store and security policies at the web-tier level. For example, if you're using IIS, you can use Integrated Windows Authentication to restrict who enters the portal. You can also use Public Key Infrastructure (PKI) or any other identity store for which the web server has built-in or extensible support. This allows you to provide a single sign-on or other custom authentication experience when logging in to use services, web applications, and Portal for ArcGIS.
Allows you to expose Portal for ArcGIS through a site name other than the default arcgis.
Allows you to expose Portal for ArcGIS through port 80 or 443.
You can only use the Web Adaptor with port 80 or 443. Using different ports is not supported.
ArcGIS Web Adaptor deployment scenarios
The ArcGIS Web Adaptor is platform independent of Portal for ArcGIS; therefore, the ArcGIS Web Adaptor you deploy does not have to match the operation system platform of your Portal for ArcGIS. For example, if you have a site comprised of Linux machines, you can deploy ArcGIS Web Adaptor (IIS) or ArcGIS Web Adaptor (Java Platform) to work with Portal for ArcGIS. Conversely, if your portal is running on Windows, you can deploy ArcGIS Web Adaptor (Java Platform) on Linux to work with Portal for ArcGIS.
Accessing your portal with ArcGIS Web Adaptor installed
After installing and configuring ArcGIS Web Adaptor, the URL that you use to access your portal will be in the format https://webadaptorhost.domain.com/webadaptorname/home. For example, if the machine hosting your ArcGIS Web Adaptor is named wa with the domain myorg.net and your ArcGIS Web Adaptor is named arcgis, you'll access the portal using the URL https://wa.myorg.net/arcgis/home.
If you have configured your portal to use HTTPS for all communication, you should update the installed portal website and help shortcut URLs to use https instead of http; otherwise, you will see failures in your browser when attempting to access the original shortcut URLs.
ArcGIS Web Adaptor setup experience
ArcGIS Web Adaptor has its own setup and installation guide which is separate from the installations for Portal for ArcGIS. You must install ArcGIS Web Adaptor on a machine running a web server. This can be a machine already running a Portal for ArcGIS or a separate machine.
There are multiple setups available for ArcGIS Web Adaptor and, depending on your web server and operation system, you will choose one of them:
- ArcGIS Web Adaptor (IIS) setup allows Portal for ArcGIS to integrate with your IIS web server running on Windows. For more information, see Installing ArcGIS Web Adaptor (IIS).
- ArcGIS Web Adaptor (Java Platform) setup allows Portal for ArcGIS to integrate with Java EE servers such as WebSphere and WebLogic. The setup is available for Windows and Linux. For more information, see Installing ArcGIS Web Adaptor (Java Platform) on Windows.
