Using Azure For Disaster Recovery – Microsoft Azure is the public cloud offering from Microsoft, the second largest cloud platform in the world. It provides cloud services such as computing, storage, networking, DevOps services, data analytics, and artificial intelligence (AI).
Azure provides a secure and scalable end-to-end backup and disaster recovery solution that you can integrate with on-premise data protection solutions. This allows organizations to automatically restore service in the event of an accidental outage, malicious attack, or other disaster. Azure backup and disaster recovery services are cloud-based and highly available
Using Azure For Disaster Recovery
Azure Site Recovery (ASR) offers Disaster Recovery as a Service (DRAAS) that organizations can use as part of their overall Business Continuity and Disaster Recovery (BCDR) program. ASR orchestrates and automates replication across cloud and hybrid environments. The service can replicate Azure virtual machines (VMs) across regions, on-premises machines to secondary datacenters, and on-premises physical servers and VMs to Azure. It can also replicate Azure Stack VMs

Small businesses can implement disaster recovery in the cloud at a lower cost by using shared solutions such as Azure Traffic Manager, Azure Virtual Networks and Site Recovery – based on services that provide complex, supported, high-performance. Availability Environment. The structure of the solution is shown below
Large organizations may need disaster recovery capabilities for systems such as SharePoint, Linux, and Dynamics CRM web servers in the on-premises data center. Azure provides a solution that enables failover of complex environments on Azure infrastructure
It has solutions in Traffic Manager, Azure Active Directory, Site Recovery, Virtual Network and VPN Gateway. These services are supported and patched by Azure in a high availability environment. The structure of the solution is shown below
The first step is to develop a disaster recovery plan, thoroughly test it to verify its effectiveness, and then implement it. Remember to include all relevant people, technology and processes needed to restore performance in your Service Level Agreement (SLA).
High Availability And Disaster Recovery For Iaas Apps
Testing your disaster recovery plan prior to implementation can help verify its effectiveness. You must complete functional readiness testing:
Failover and failover testing can help you verify that application-dependent services remain stable when restored during the disaster recovery process. Determining the effect of changes in operations and system failures and failures can be difficult. Ideally, you should test these activities to avoid problems in real situations.
Azure supports manual failover for many services and sometimes provides failover testing for disaster recovery exercises. You can also simulate an outage by deleting or shutting down Azure services. Additionally, you can set up automated tests for functional responses to ensure functional functionality.
You must evaluate and determine the impact of interruptions on each service and how the application responds to those interruptions. When a service includes features to support availability and stability, evaluate each service independently to strengthen the overall disaster recovery plan. For example, Azure Event Hub supports failover to secondary namespaces.

Disaster recovery plans should define procedures for network incidents. If parts of the network are unavailable, this problem can prevent you from accessing applications or data. You can respond to this problem by running many applications with reduced performance. However, If you can’t reduce the activity, try failing in another area to avoid application timeout.
Azure is logically and physically divided into units called regions. Each region includes one or more data centers. Many regions also support Availability Zones (AZs) that provide greater resiliency during downtime. You can adjust the availability of your applications. Can use AZ areas to improve
Your plan should also account for disasters that affect entire regions or AZs. For example, natural disasters can destroy entire facilities and network failures can cause downtime. You can address this by distributing applications across regions and AZs. Can mitigate problems If a disaster occurs in one region, you have data and software in another active region
Do you need to back up data to on-site storage as part of your disaster recovery setup? Provides low-cost disk-based storage technology that allows you to back up data locally with up to 1.5 petabytes of capacity. You can set up the device at a remote site and use our data management tools to save data there.
Microsoft Azure Disaster Recovery
Another deployment option is a hybrid cloud configuration. You can back up data on a local device, then replicate it to the cloud for DR purposes. It combines the low latency of local storage with the stability of the cloud. Helps narrow down your search results by instantly suggesting possible matches as you type.
If you’re running virtual machines in Microsoft Azure, and you want to make sure your servers are protected from downtime, there are a number of things you’ll want to look at in terms of availability. You need to ensure that you have the required uptime in the Azure region in which your virtual machine is running. For this, we have availability features like premium storage with various storage options, which provide single-instance VMs with 99.9% SLA. Does and availability sets and availability zones, which help domain controllers extend across groups of virtual machines such as data centers or multiple regions within a single region. In most cases, you’ll also want to protect virtual machines from region blocking. For this we have Azure Site Recovery (ASR), which allows you to seamlessly replicate Azure virtual machines across different Azure regions and restore them as needed. But fails in other areas.
Setting up Azure Site Recovery for Azure virtual machines (VMs) could be simple. In my case, I have a virtual machine running in the Western Europe Azure region Before you start setting up disaster recovery for Azure VMs, make sure you have properly planned and designed your environment. I suggest you pay attention to the following words:
There are several ways that you can configure disaster recovery for Azure VMs; In my case, I’ll start the replication setup directly from the source virtual machine I want to replicate to. However, you can configure this from Azure Recovery Services Vault or by using Azure Powershell or Azure CLI. In the menu I click on Disaster Recovery in the Operations group I can start right away the first thing I set up is that it will allow me to select an available target area where I want to fail over to my VM in the event of a disaster.

As a next step, you will be able to configure some advanced settings. Azure Site Recovery will give you some suggestions and create resources for you if needed. You must have resources, such as storage accounts, virtual networks, resource groups, etc., that are needed. Will happen when you fail over a virtual machine.
It will take some time for the security to be installed and the initial data of the virtual machine to be copied
After you have configured the disaster recovery options for the virtual machine and completed the initial backup, you can now see some additional information and a graphical view that helps you understand how the resources are connected.
Now you have two options; You can perform failover, which will perform a production failover of your virtual machine. If the source region is still available and the Azure VM is running, you can also allow ASR to shut down the source machine and reload the latest changes. so that you don’t lose any data. However, the area containing the VM resource is still accessible, and it is unlikely, if not, that ASR will accept the last recovery point.
Create/customize Recovery Plans In Azure Site Recovery
Disaster recovery preparedness is great. However, you want to make sure it works if you need it. You don’t want to wait to see if everything is set up correctly. Test it. Fail it. Test it. Failover has the ability to fail over virtual machines in a target area, so you can test virtual machines and applications without affecting production deployments.
If you have multiple VMs, you want to fail over in a specific order and perhaps run an additional script to completely fail over from one area, ASR also gives you a recovery plan. Recovery plan great for more complex situations than a single virtual machine
Azure Site Recovery as a Service (DRaaS) is Azure’s built-in disaster recovery. I showed you how you can plan for Azure DR. However, you can also use Azure Site Recovery to replicate on-premises servers to Azure for DR.
