Internal load balancer is used to balance and distribute the requests sent by Adeptia Connect GUI Portal on all the nodes of a cluster. You need to configure the following:

• IP address of all the nodes of a cluster beneath the load balancer.
• Sticky session: For internal load balancer, enable cookie stickiness and use application generated cookie 'JSESSIONID'.
• Deploy SSL: Steps to configure SSL varies from load balancer to load balancer.
• Set connection idle timeout to 180 seconds.

Verifying Internal Load Balancer Configuration

After the load balancer is configured, you need to verify whether load balancer is configured successfully or not. To verify:

Login to Connect Server using load balancer IP Address in the URL format:

<protocol_name>://<IP_address>:<port_number>

Configuring Internal Load Balancer for Health Checkup

Consider a clustering environment working with two nodes where the Load Balancer sends request(s) to the WebRunner(s). In case, Kernel of any of the two nodes goes down, the Load Balancer keeps on sending the request to the WebRunner. This happens because Load Balancer does not interact with the Kernel resulting in the request failure from the node where Kernel is down.
