Controller HA in AWS¶
Enable Controller HA¶
Aviatrix Controller HA in AWS leverages auto scaling group and Lambda function to perform monitoring, launching a new controller and restoring configuration when the active controller instance become unreachable. When a new controller is launched, the existing controller is terminated by auto scaling group and its EIP is associated to the controller. Existing configuration files are restored which gives you a seamless experience when failover happens.
