If this bastion host becomes unavailable, a second host is provisioned.* * In the private subnets: ** Two Amazon EC2 instances running as IRIS mirror nodes 1 and 2 in a security group across Availability Zones 1 and 2. Data is replicated in real time between the nodes. ** One Amazon EC2 instance acting as a mirror arbiter in Availability Zone 3. The arbiter checks the health of the two mirror nodes and detects when a node is offline. * A Network Load Balancer, which distributes inbound traffic across the workload instances that you want to protect from outside access.
