# VMware Cloud Disaster Recovery as a Service (DRaaS) Overview

VMware Cloud Disaster Recovery as a Service (DRaaS) provides VMware cloud computing resources in Selectel to build a disaster-resilient infrastructure for your cloud. DRaaS requires no capital expenditure or additional hardware.

You can configure DRaaS for your VMware (On-Premises) infrastructure, a private cloud, or a public cloud hosted by another VMware provider.

## Operating Principle \{#principle-of-operation}

Infrastructure resiliency is achieved by replicating your cloud powered by VMware from your primary site to the Selectel cloud.

Virtual machines are synchronized according to a disaster recovery plan that you create when setting up DRaaS. In the event of a disaster at the primary site, you can quickly launch virtual machines at the secondary site with minimal recovery time objectives (RTOs) and recovery point objectives (RPOs).

## Solutions \{#solutions}

Disaster recovery to a VMware cloud is available in two solutions:

* VMware Cloud Director Availability™ is a DRaaS service integrated into VMware Cloud Director®. It is designed for cross-cloud migration and disaster recovery. It allows you to configure replication between a client's VMware vCenter Server and a VMware-based public cloud in Selectel. You can back up your infrastructure to the Selectel cloud and vice versa;
* Veeam Cloud Connect Replication™ — a DRaaS service integrated into Veeam Backup & Replication™. It is designed for disaster recovery using VM replication. In the event of a disaster, you can launch individual VMs (Failover Now) or the entire infrastructure using a prepared plan (Failover Plan).

## Clusters \{#clusters}

Since replication occurs to a public cloud powered by VMware, its [clusters](/public-cloud/about/about-public-cloud.mdx#clusters) are used for disaster recovery. You can choose any public cloud cluster as your secondary site.
