The Basics of Azure Site Recovery

by | Aug 26, 2020 | Cloud

Most organizations, especially in these days of remote working during COVID-19, are searching for a method to protect our organizations from unexpected disasters or situations.  Azure Site Recovery, or ASR, allows you to synchronize your on-premises server infrastructure to a cool cloud based duplicate environment.  How can this help your business?  If you have a natural disaster, extensive power outage, fire, employee or outside based destruction, ransomware. or cyber security incident, you can get your organization up and running quicklyASR allows you to have your environment up and back in business in hours instead of days, weeks, or months.  ASR is a product that allows you to spin up servers in Azure or another company owned site. ASR IMG 1

You plan and test your incident response plan either as scheduled/planned or because of unplanned failovers.  As much as we like to plan for the future, sometimes we need to react to an incident occurring to the organization in real time.  Examples of this include ransomware incident, bad weather, or the tragedy of a fire impacting our core business.  ASR allows leadership to sleep at night knowing that your key business systems and processes can remain intact after an incident affects your organization. ASR Img 3

Azure Site Recovery has two configurations with either a Hyper-V Virtual Server or VMware/Physical Servers.  With the Hyper-V configuration, you can go directly from the Hyper-V virtual machine to Azure Site Recovery.  However, with VMware/Physical servers you would need to deploy a management server to coordinate the servers going to Azure Site Recovery. 

 Key Features: 

  • Relatively platform agnostic working with Microsoft, VMware, and Linucan be either physical or virtualized. 
  • Reduce the cost of deploying, monitoring, patching, and maintaining on-premises disaster recovery infrastructure by eliminating the need for building or maintaining a costly secondary datacenter. Allows you to have a cost-effective DR site in Azure for when you need it separate from your already maintained production environment. 
  • Simple Azure Site Recovery set up by replicating an Azure VM to a different Azure region directly from the Azure portal. As a fully integrated offering, Site Recovery is automatically updated with new Azure features as they’re released.  
  • Application consistent snapshots for both single and N-Tier applications.  Minimize recovery issues by sequencing the order of multi-tier applications running on multiple virtual machines.  
  • Ensure compliance by testing your disaster recovery plan without impacting production workloads or end users, and keep applications available during outages with automatic recovery from on-premises to Azure or Azure to another Azure region. 
  • Near-synchronous replication with snapshots every 5 minutes for the first hour and then configurable hourly for up to 72 hours. 
  • Integration with SQL Server AlwaysOn and several partnerships with other applications including other application level replication technologies. 
  • Flexible recovery plans along with the availability for testing.

Security Features: 

  • Encryption in transit is supported for replicating virtual or physical servers to Azure or from on-premises to another organizational site.  Encryption at rest is supported for servers going to Azure only. 
  • Data flows through a secure, authenticated, and certified HTTPS channel. 
  • Customer maintains the encryption certificate
