Configuring the load balancer
A load balancer is mandatory for the multi-node HA-ready production setup.
x-forwarded-for
header to the request it sends to the server. This header includes the original client's IP address. The server can then
read this header to retrieve the client's IP address.
Automation Suite supports two types of configuration for the load balancer, as shown in the following sections.
You can configure the load balancer to use session persistence or sticky sessions, but it is not a requirement.
Currently, Automation Suite supports only a Layer 4 (network layer) load balancer.
The load balancer does not support TLS encryption and termination. For effective service operation, make sure to configure your load balancer to facilitate traffic pass-through.
If you are using the Azure Internal Load Balancer (LB) for deployments, you can encounter issues with the calls from the backend Virtual Machine (VM) to the LB frontend IP. The issues occur due to source IP and MAC address mismatch of the network packet. This prevents the recipient from working out the correct response path, resulting in the failure of calls from the VM to the LB. For more details, see Azure Load Balancer Components limitations and Backend Traffic Troubleshooting.
This is the recommended configuration for the load balancer.
You need to create two backend pools that meet the following requirements:
-
Server Pool
- Consists of all the server nodes.
- There must not be any agent nodes in the Server Pool.
-
Node Pool
-
Consists of all the server nodes and non-specialized agent nodes. Specialized agent nodes include
task-mining
,gpu
,asrobots
.

Ensure you have the following ports enabled on your firewall for the source of load balancer:

For any ports other than HTTPS, we recommend it is not exposed outside the cluster. Run your nodes behind a firewall / security group.
If you have a firewall setup in the network, make sure that it has these ports open to allow traffic from those ports.
Refer to the following illustration for more details on the configuration.
This configuration does not have resilience to nodes going down during installation.
If the primary server is down or deleted, cluster configuration needs to be updated.
FQDN of the primary server needs to be remapped to a different machine in the cluster that is available.
