How do you handle High Availability?

The system is stateless and based on multiple servers and multiple regions with a replication of the database.

In addition to the AWS regions in production, the AWS Frankfurt region is also on standby as a failover option.

In case of failure of one server, Screena's load balancer automatically detects it and sends all the requests to the available servers.

We have a full weekly backup and an hourly snapshot of the environment.
