Load balancing considerations

It is recommended that a load balancer is used in front of ECS.

In addition to distributing the load across ECS cluster nodes, a load balancer provides High Availability (HA) for the ECS cluster by routing traffic to healthy nodes. Where network separation is implemented, and data and management traffic are separated, the load balancer must be configured so that user requests, using the supported data access protocols, are balanced across the IP addresses of the data network. ECS Management REST API requests can be made directly to a node IP on the management network or can be load balanced across the management network for HA.

The load balancer configuration is dependent on the load balancer type. For information about tested configurations and best practice, contact your customer support representative.
