About Disaster Recovery Between Oracle Cloud VMware Solution Sites in One Region

If you prefer to run their primary and recovery sites in Oracle Cloud, use this deployment model. The primary site resides in Oracle Cloud VMware Solution in one availability domain in a region, and the recovery site resides in Oracle Cloud VMware Solution in another availability domain in the same region.

This model best suits near-site disaster recovery requirements and applies only for Oracle Cloud Infrastructure regions with multiple availability domains. This article describes the architecture, configuration considerations, and implementation prerequisites for this deployment model.

Architecture

The following figure shows a detailed architecture of the connection between two Oracle Cloud VMware Solution sites within one region for disaster recovery.

Understand Assumptions and Key Considerations

Following are assumptions and key considerations for this deployment model.

  • You have a VMware SRM license to use in Oracle Cloud VMware Solution. Oracle Cloud VMware Solution doesn’t provide an SRM license as part of the universal credit subscription.
  • Only vSphere Replication is supported.
  • VLANs specific to an availability domain, so you can’t use regional subnets.
  • You are familiar with Oracle Cloud Infrastructure and VMware.
  • You are familiar with DNS configurations on Microsoft Windows.
