The system and hardware requirements to run ArcGIS Web Adaptor are listed below. For information about earlier versions, see Archives.
Review the deprecation notice to determine whether your hardware and software are still compatible with the current ArcGIS version.
ArcGIS Web Adaptor (IIS)
ArcGIS Web Adaptor (IIS) can be installed on a Microsoft Windows machine and integrated with an Internet Information Server (IIS) web server.
Microsoft IIS required components
Microsoft Internet Information Server (IIS) must be enabled along with specific IIS components. The setup will not proceed if IIS is not detected and specific IIS components enabled.
If you have IIS 10 installed but are missing required IIS components, the setup will display the IIS requirements verification dialog box. This gives you the option to allow the installation to automatically enable any missing required IIS components. To do so, click I agree.
Note:
If you're going to perform a silent installation of ArcGIS Web Adaptor, all required IIS components must be enabled manually. The setup will not automatically enable missing IIS components when you perform a silent installation.
To learn how to enable IIS on your operating system and optionally enable the missing IIS 10 components manually, see Manually enable IIS and required IIS components.
Caution:
To successfully install and configure ArcGIS Web Adaptor, you must enable IIS and the required components before installing the prerequisites specified in the next section.
Prerequisites
The following prerequisites must be installed on the machine where ArcGIS Web Adaptor (IIS) will be installed:
Note:
You must install the ASP.NET Core Runtime - Windows Hosting Bundle, which includes the .NET Runtime and IIS support.
Caution:
If you installed the ASP.NET Core Runtime - Windows Hosting Bundle before enabling IIS and the required components, you must repair the bundle installation using the bundle installer.
Supported web servers
The IIS web server versions available on supported Windows operating systems are supported for use with ArcGIS Web Adaptor (IIS).
Updates on these operating systems and web servers are supported unless otherwise stated. The operating system version and updates must also be supported by the application or web server provider.
Maximum installation instances
The maximum number of instances of ArcGIS Web Adaptor (IIS) you can install on a single machine depends on how you install the first ArcGIS Web Adaptor instance. If you install the first instance using the ArcGIS Web Adaptor setup program, you can install a maximum of 51 instances of the same version of ArcGIS Web Adaptor on a single machine. However, if you install the first instance using ArcGIS Enterprise Builder, you can install a maximum of 50 instances of the same version or ArcGIS Web Adaptor on a single machine. If more instances are required, install them on a separate machine.
If you have earlier versions installed on the machine, you are not required to uninstall them. For example, you can have 5 instances of ArcGIS Web Adaptor at an earlier release and 51 instances of ArcGIS Web Adaptor 11.3 installed on the same machine. The maximum value only applies to instances of the same software version.
Hardware requirements
ArcGIS Web Adaptor (IIS) requires a minimum of 8 GB of memory, with more potentially required depending on the number of ArcGIS Web Adaptor instances installed and the number and size of the requests received.
For hardware considerations when upgrading to ArcGIS Web Adaptor 11.3, see Upgrade ArcGIS Web Adaptor.
