Microsoft Azure Cloud Migration Services

Scale & Automate Your Infrastructure by Migrating to the Microsoft Azure Cloud

Microsoft Azure Cloud Migration

In the past few years, cloud adoption has increased significantly, as it provides considerable value over traditional datacenters—achieving greater scalability, cost efficiency, and improved performance.

Many organizations are now looking to quickly take advantage of this value by migrating their existing applications and workloads. But cloud migration requires careful planning and strategy. One of the keys to cloud success is to determine the optimal platform and priorities for running business applications. Once considered optional, these applications are now central to infrastructure decisions and achieving company goals.

To enable successful migration, it’s important to have a strong plan in place that covers the end-cloud environment, training, and, most importantly, the readiness of your workloads and applications. To do this, you need to determine how to successfully create the initial technical plans and business justification, ensure your workloads will run as expected, and perform the migration with limited impact on the business.

The benefits of cloud are universal—reduced running costs, faster modernization capabilities, and increased security. But often, specific initiators first kick off the discussion within an organization, including:

Operational efficiencies and reduction of operating expenses
Decreased time to market/release.
Support for scalability requirements that are more cost effective
Renewal of datacenter or hardware leasing
Renewal of licensing
Application development and modernization.

How To Approach Cloud Migration with Microsoft Azure?

Your migration could require you to run parallel and iterative migration processes as you progressively move your applications and workloads to the cloud.

Microsoft Cloud Migration Methodology

This is also known as “redesigning” an application to modernize it—that is, to transform it with a modular architecture. Rearchitecting is modifying or extending an existing application’s code base to optimize it for a cloud platform and for better scalability. Cloud provider services can be used directly as backend services of modern apps, which are highly scalable and reliable. This is likely the most time-consuming way to migrate an app to the cloud because it requires app code changes. One example of rearchitecting would be decomposing a monolithic application into microservices that work together and readily scale on Azure. Another example would be rearchitecting a SQL Server database to make it a fully managed Azure SQL Database

 Revise the existing application by aggressively adopting PaaS or even software as a service (SaaS) services and architecture. The process encompasses major revisions to add new functionality or to rearchitect the application for the cloud. An example of this stage would be code redesign to decompose the original application into smaller chunks, and then deploy using modern cloud provider services.

This refers to moving or discarding an existing application and replacing it with commercial software delivered as a service, or SaaS. SaaS provides a complete software solution that you purchase on a pay-as-you-go basis from a cloud service provider. When you choose this option, all underlying infrastructure, middleware, app software, and app data are managed by service providers and located in their datacenters. The service provider manages the hardware and software and, with the appropriate service agreement, will ensure the availability and security of the app—and your data as well. SaaS allows your organization to get quickly up and running with an app at minimal upfront cost. Typically, you migrate existing data to the SaaS environment. Application data import/export is achieved with an API or configuration/admin console.

Also referred to as “lift and shift,” this stage entails migrating your physical servers and virtual machines as-is to the cloud. By simply shifting your current server environment straight to IaaS, you reap the benefits of cost savings, security, and increased reliability. In the new rehosted cloud model, hardware and operating systems you previously managed yourself are now managed by the cloud provider. All other aspects of the workload or application remain the same. This is the most popular migration approach, as it lets organizations move quickly, with little risk or impact, and receive immediate benefits. It also allows customers to see the lower total cost of ownership (TCO) faster, enabling investment back into the migration process to evolve through the model.

Also known as “repackage,” this stage involves using additional cloud provider services to optimize the cost, reliability, and performance by refactoring your applications. In lift and shift, you were only taking advantage of the provider-managed hardware and OS, but in this model, you also take advantage of cloud services to drive down cost. You continue to utilize your current application as-is, with some minor application code or configuration changes, and connect your application to new infrastructure services such as containers, database, and identity management systems. By employing modernized services in this scenario, you can lower cost and management.

Frequently Asked Questions (FAQs)

Commonly asked questions related to Microsoft Azure Cloud Migration

Does Azure Migrate support assessment of only VMware workloads?

Yes, Azure Migrate currently only supports the assessment of VMware workloads. Support for Hyper-V is in preview, please sign up here to get access to the preview. Support for physical servers will be enabled in the future.

Does Azure Migrate need vCenter Server to discover a VMware environment?

Yes, Azure Migrate requires vCenter Server to discover a VMware environment. It does not support discovery of ESXi hosts that are not managed by a vCenter Server.

How is Azure Migrate different from Azure Site Recovery?

Azure Migrate is an assessment service that helps you discover your on-premises workloads and plan your migration to Azure. Azure Site Recovery, along with being a disaster recovery solution, helps you migrate on-premises workloads to IaaS VMs in Azure.

How is Azure Migrate different from Azure Site Recovery Deployment Planner?

Azure Migrate is a migration planning tool and Azure Site Recovery Deployment Planner is a disaster recovery (DR) planning tool.

How does the on-premises site connect to Azure Migrate?

The connection can be over the internet or use ExpressRoute with public peering.

What network connectivity requirements are needed for Azure Migrate?

For the URLs and ports needed for Azure Migrate to communicate with Azure, see URLs for connectivity.

Can I harden the VM set up with the OVA template?

Additional components (for example anti-virus) can be added into the OVA template as long as the communication and firewall rules required for the Azure Migrate appliance to work are left as is.

Would there be any performance impact on the analyzed ESXi host environment?

With continuous profiling of performance data, there is no need to change the vCenter Server statistics level to run a performance-based assessment. The collector appliance will profile the on-premises machines to measure the performance data of the virtual machines. This would have almost zero performance impact on the ESXi hosts as well as on the vCenter Server.

Does Azure Migrate support Enterprise Agreement (EA) based cost estimation?

Azure Migrate currently does not support cost estimation for Enterprise Agreement offer. The workaround is to specify Pay-As-You-Go as the offer and manually specifying the discount percentage (applicable to the subscription) in the ‘Discount’ field of the assessment properties.

What is dependency visualization?

Dependency visualization enables you to assess groups of VMs for migration with greater confidence by cross-checking machine dependencies before you run an assessment. Dependency visualization helps you to ensure that nothing is left behind, avoiding unexpected outages when you migrate to Azure. Azure Migrate leverages the Service Map solution in Azure Monitor logs to enable dependency visualization.
