# 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](/resources/faq/hosting-and-deployment/what-aws-regions-do-you-operate-as-of-now.md), 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.
