The Azure Site Recovery service contributes to your business continuity and disaster recovery (BCDR) strategy by orchestrating replication, failover and recovery of virtual machines and physical servers. Machines can be replicated to a secondary on-premises data center or in this case, to Azure. Much awaited update for VMWare migration and disaster recovery with ASR is now available since Monday.
With this latest update, users can protect and replicate thir VMWare VMs and physical servers to Azure, without the need to deploy any replication or orchestration components in Azure IaaS. This helps users to drastically reduce their additional costs involved with this and improve the management capabilities and simplicity of ASR solution.
This enhanced functionality was in Private Preview since October, 2015 for selected customers. With the feedback received from them has helped immensely to shape up the latest update and now is available for everyone.
Below table will help you understand the changes and enhancements released with this update.
Below two diagrams will help you to understand the architecture of the legacy VMWare to Azure and enhanced VMWare to Azure options.
To use this new enhanced update, go to your Azure Site Recovery Vault settings, and select “Between an on-premises site with VMWare/physical servers and Azure”. It will show the word New in green color next to the drop down list once selected, to indicate that you’re going to use the enhanced version.
However, the old method of using components on the Azure IaaS is not out of service yet. If you want to deploy an ASR solution with old architecture, yes, you can do so by selecting “(Legacy) Between an on-premises site with VMWare/physical servers and Azure”.
However, Microsoft is recommending that you use the new enhanced version for future deployments as well as to upgrade your existing legacy deployments to the new enhanced version.
