Datometry Hyper-Q does not maintain state or have data at rest. For high availability, multiple instances of Hyper can be deployed behind a load balancer that fails over connections to available instances. For on-premise deployment, the exact setup depends on the load balancer and availability configuration in the data center. For cloud deployment, you can use the cloud provider's standard load balancer service in combination with deployments of Hyper-Q in two or more availability zones. The following diagram illustrates the reference architecture on Amazon Web Services.
