# Setting up disaster recovery

To explain the disaster recovery setup in SonarQube Server’s Data Center Edition (DCE) deployed on Kubernetes, we use the example of a system deployed on Azure Kubernetes Service (AKS). But the overall concept can be adapted to Google Cloud Platform (GCP) or Amazon Web Services (AWS) with a few modifications.

For the setup explained in this section, you need a basic understanding of Azure Cloud Services.

A forced Elasticsearch reindex is required after a failover event of the Kubernetes cluster hosting the SonarQube DCE server.
