You can create Avi Load Balancer profiles, like application, persistence, and network profiles. You can also create, for example, a single persistence profile and provide that for another team in your organization to use later.

These sample templates cover several scenarios for creating Avi Load Balancer profiles. The first example shows how you might create a template that contains an application profile, a persistence profile, and a network profile. The second example shows a template that contains different types of persistence profiles that are available with Avi Load Balancer along with a cloud zone allocation helper. The remaining examples focus on single persistence profiles.

The template examples cover the minimum requirements for creating Avi Load Balancer profiles. When creating templates that are relevant to your organization, keep in mind that other properties might be required.

For more information about profiles, see the Load Balancing section in the VMware NSX Advanced Load Balancer Configuration guide.

Application, persistence, and network profiles

This sample Avi Load Balancer template uses an application profile, a network profile, and a persistence profile.

The application profile determines the behavior of the virtual service. The network profile determines the type and setting of the network protocol. Both the application profile and the network profile are associated with virtual services. The persistence profile governs the settings that make a client stay connected to the same server for a specified duration of time. It is attached to an Avi Load Balancer pool.

Persistence profiles and allocation helper

This sample template contains all of the persistence profile types along with an allocation helper.

The cloud zone allocation helper assists in directing the deployment request to the desired VMware Avi Load Balancer controller based on tags on the cloud account.
