How does Sqreen ensure high availability?


Every part of the Sqreen service uses redundant services (e.g., multiple load balancers, application instances, replica databases) in order to reduce the impact in the case of a failure. Redundancy is effective on 3 different data centers (AZ). As part of regular maintenance, servers are taken out of operation without impacting availability.

We keep hourly encrypted backups of data in multiple regions on AWS. While never expected, in the case of production data loss (i.e., primary data stores lost), we will restore organizational data from these backups.

In the event of a region-wide outage, Sqreen will bring up a duplicate environment in a different AWS region.
