Our client was in a situation where they had no disaster recovery or business continuity plan in place. All of the company’s servers and equipment were operating in an on premises data center. When BlueSilverShift got engaged and took them on as a managed services client, one of the first things that we did was to recommend that they remedy this situation to ensure that any physical outage would not impact their operations.
As it turned out, before the client could approve the move to Azure, they had a massive storage area network (SAN) outage that brought down 100% of the servers in their environment. The only solution was to restore everything from backup.
Their operation was completely down for a total of two days and partially down for close to a week while waiting for the full restoration of all services. This was a significant wake-up call for the client, after which they fast tracked approval for the migration to leverage the Azure cloud.
The first step that we took was to implement Azure Site Recovery (ASR), which was configured to replicate all of the client’s servers in Azure for disaster recovery. Within 10 days, all of their servers were completely replicated to the cloud, at which point we were able to begin conducting disaster recovery failover testing scenarios without impacting regular business operations.
- Test failovers were conducted
- Replicas of the backed-up servers were restored to an isolated network in Azure
- User acceptance testing was conducted to ensure that all applications operated as expected
- An ongoing plan was implemented to ensure that periodic disaster recovery scenarios are tested with this client as part of regular managed services and business continuity assurance
This was a very cost effective option which allowed us to provide the best service because the replicas of the hosts in Azure can be powered down in a cold/warm standby scenario, meaning that a company no longer has to pay for unused compute capacity or purchase expensive equipment that duplicates what they have on premises.
At the end of the implementation of Azure Site Recovery, the client had a completely redundant and secure disaster recovery environment located in the Azure public cloud environment in entirely different seismic zones. This gave their board of directors the assurance needed to know that their business could continue to operate in the event that the on premises system failed in a major way again.
BlueSilverShift implemented a solution leveraging Azure Site Recovery and is now managing their IT services.
