United Airlines Uses Azure Site Recovery to Build a Disaster Recovery Solution
To address the need for an enterprise-ready disaster recovery solution, in June 2013 United Airlines joined the Rapid Deployment Program (RDP) for Windows Server 2012 R2. “Now that we are more virtualized, we are looking at a whole new approach to DR, where flexibility and cloud computing combine to provide a resilient solution that we can tailor to meet our needs,” says Wilson. “It made sense to continue on our cloud journey with a Microsoft DR solution.”
Hyper-V Replica offers a data replication solution that replicates virtual machines within a site or to a remote site. The latest version of Hyper-V Replica provides the flexibility that United is looking for, with variable replication frequency—from 30 seconds up to 15 minutes—and support for extended replication to a third site. And the new DR management service, Microsoft Azure Site Recovery, answers the airline’s need for a highly available DR solution because it is delivered as a cloud service running in the Microsoft Azure environment. Azure Site Recovery offers orchestration at scale delivered via recovery plans, so United IT staff can bring up applications in a desired manner at a low recovery time objective. While Azure Site Recovery is a feature of Windows Server 2012 R2, it supports backwards compatibility with all versions of Hyper-V Replica.
With Azure Site Recovery:
Safeguard complex workloads against outages
Support heterogenous environments (including Hyper-V)
Leverage computer resources
Reduce infrastructure costs by migrating workloads to Azure
Using Azure as a destination for disaster recovery eliminates the cost and complexity maintaining a secondary site, and replicated data is stored in Azure Storage, with all the resilience that provides. Site Recovery provides test failovers to support disaster recovery drills without affecting production environments. You can also run planned failovers with a zero-data loss for expected outages, or unplanned failovers with minimal data loss (depending on replication frequency) for unexpected disasters. After failover you can failback to your primary sites. Site Recovery provides recovery plans that can include scripts and Azure automation workbooks so that you can customize failover and recovery of multi-tier applications.
