You can configure load balancer settings in your network profile configuration.

You can add an existing load balancer to a network profile by using the Load Balancer tab.

You can add a load balancer to a cloud template design by associating it to a network profile that contains one or more load balancers or directly by using a load balancer resource in the cloud template design canvas or code.

Examples for including a load balancer VIP based on security group use in a network profile

There are two types of security groups that you can use in a network profile – an existing security group that you select from the Security Groups tab and an on-demand security group that you create by using an isolation policy on the Network Policies tab.

When a load balancer VIP is associated to a security group based on network profile settings, the security group configuration is supplied by the network profile.

The following table illustrates some sample scenarios.

Cloud template design topology - associated resources Network profile configuration Security group membership
One-armed load balancer with VIP on private network, and a machine on the same private network. The selected network profile uses isolation policy defined as an on-demand security group. The machine NIC and the load balancer VIP are added to the isolation security group.
One-armed load balancer with VIP on private network, and a machine on the same private network. The selected network profile uses an existing security group and uses isolation policy defined as an on-demand security group. The machine NIC and the load balancer VIP are added to the isolation security group and the existing security group.
Two-armed load balancer with VIP on a public network and machine on a private network. The selected network profile uses an existing security group and uses isolation policy defined as an on-demand security group. The machine NIC and the load balancer VIP are added to the isolation security group and the existing security group.
Two-armed load balancer with VIP on a public network and a machine on a private network. The selected network profile uses an existing security group. The machine NIC and the load balancer VIP are added to the existing security group.
Two-armed load balancer, VIP is on network 1 and the machine is on network 2.
Two network profiles:
  • Network profile 1: Uses an existing security group 1.
  • Network profile 2: Uses an existing security group 2.

The load balancer lands on network profile 1 and the machine lands on network profile 2.

The load balancer VIP is added to security group 1 and the machine NIC is added to security group 2.
