Web applications obtain access to the content through a tiered infrastructure. The tiers are depicted in the following diagram:
There can be multiple service application proxy groups. You can logically associate your web applications in these proxy groups. In this recipe, we will show how to modify the proxy group membership.
You must have Farm Administrator privileges to Central Administration.
Create an application proxy group as outlined in the preceding recipe. In our example, we have created a group called SAPGFinancial.
- Open Central Administration and click Application Management.
- The third section is Service Applications. Click the Configure service application associations option. You will see a screenshot similar to the following:
- Click on the
SAPGFinancialgroup option. A pop up will appear that will enable you to choose the service applications you want to associate with this application proxy group.
- Choose the service applications proxies you wish to enable/disable and click OK.
As seen in the previous recipe, we created a service application proxy group. Then when the web application was created, we associated it with the service application proxy group; in this case, it was SAPGFinancial. Initially, there were no service application proxies in this group.
Now that the web application is associated with the proxy group, it may consume the service application resources. As you can see from the preceding figures, service applications can exist in multiple application proxy groups.
However, it is important to note that a web application can be associated with only one application proxy group.
You can use PowerShell to modify service applications that are associated with application proxy groups. This is powerful when scripting your environments for a seamless installation.
