In this section, we are going to create an application pool. This allows you to create a pool that contains a number of different applications. You may want to create application pools to reflect different departments, for example. To configure an application pool, perform the following steps:

1. From the View Administrator, expand the arrow for Catalog from the Inventory pane on the left, and then click on Application Pools (1), as shown in the following screenshot:

2. Now click on the Add... button (2).

3. You will now see the Add Application Pools configuration screen, as shown in the following screenshot:

4. From the Select an RDS farm drop-down menu, select the farm that we created previously for our published applications. In the example lab, select the farm called Horizon-Published-Apps from the menu.
5. Next, click the radio button for Select installed applications. This will automatically list all the applications that are installed on that particular RDSH server. There is also the option to add an application pool manually.

6. From the list of applications, check the box for the applications you want to add to the application pool. In the example, we have selected PowerPoint 2016 (3) and Word 2016 (4), as well as Calculator, Paint, Excel 2016, Publisher 2016, and Outlook 2016.
7. You then have the option to check the Pre-Launch box. That means the applications in the pool are launched and ready when the end users click on them to speed up launch times.
8. The next option is for Connection Server restrictions, which allows you to configure tags for which Connection Servers you can connect with.
9. Finally, you can configure the Category Folder, which allows you to add a shortcut on the end user's device.
10. When you have selected all the required applications, click the Next > button to continue.
11. You will now see the Edit ID and Display Name screen. Here, you can choose to edit the ID and the display name for the applications if you want to. This is shown in the following screenshot:

12. Also, check the Entitle users after this wizard finishes box to automatically launch the user entitlement configuration, which we will complete in the next section.
13. Click the Finish button to complete the configuration. You will then see that the application pool has been created.

Now that you have your application pool all set up and ready to go, the next step is to entitle end users to the pool and allow them to launch applications.
