What is Cloud Migration?
It is the process of transferring data, services, and other business elements to a cloud computing environment that results in better Scalability, and efficiency and also helps reduce the IT costs of the business.
What is Azure?
Azure is a Cloud Computing platform provided by Microsoft and launched in February 2010. In simpler terms, Microsoft Azure is a platform that enables users to engage in agile cloud computing and is designed for creating and managing apps and services through Microsoft data centers.
Microsoft Azure operates more than 200 physical data centers worldwide, each of which has several connected computer servers.
Here are a few key facts about Microsoft Azure:
- Flexible – Modify the computing resources as necessary.
- Open- almost every OS, language, tool, or framework is supported.
- Reliable- 99.95% availability SLA (Service-Level agreements) and 24×7 tech support
- Global- Data housed in geosynchronous data centers
- Economical- pay for what you use
Azure cloud service is the best public cloud service in the market since it is quickly adaptable and economical.

What is Azure Migrate?
Microsoft’s Azure Migrate is a tool that helps businesses to monitor the discovery, evaluation, and migration of on-premises workloads and data to the Azure environment with the help of a centralized portal.
Azure Migration Process
A four-step process is followed for migrating applications and workloads to Azure.
Stage 1: Assess
You must explicitly outline your goals and objectives for migration during the initial stage.
Next, calculate how much you can save by transferring your on-premises infrastructure to the cloud – Microsoft offers a useful calculator that may assist you with this.
You must compile a list of all the applications—that is, all the physical and virtual servers—that you’re using in your on-premises environment for the last step of the Assess phase. This data can be used to map your servers and detect prerequisites, and dependencies. According to your goals and any dependencies, this will help you decide which apps to migrate to the cloud first, providing a strong foundation for your Azure migration plan.
Stage 2: Migrate
You must decide on your cloud migration approach for the second stage of the cloud migration process. There are several alternatives available:
- Rehost
- Refactor
- Rearchitect
- Rebuild
Stage 3: Optimize
You’re ready to optimize once you’ve chosen a cloud migration approach that fits your goals and objectives and successfully moved your on-premises environment to Azure. Anything can be optimized, including corporate operations and cloud computing costs.
Stage 4: Secure&Manage
The Azure cloud migration process’s final phase is all about security. Microsoft provides many market-leading security tools and services that provide comprehensive visibility into potential security risks and superior cloud security management. Microsoft offers you all the resources you need to safeguard your cloud environment’s data and keep an eye on its health, from Azure Security Center to Azure Log Analytics, so you can be confident in its security and top performance.
Azure Migration Tools
To move data from on-premises to the cloud, Azure offers a variety of tools and services. The business justification for migration determines the technologies to be used. Let’s look into a few such tools:
Azure Migrate
Azure Migrate offers a streamlined migration, modernization, and optimization solution for Azure. Every pre-migration stage, including discovery, evaluations, and the proper scaling of on-premises resources for infrastructure, data, and apps, is included. The range of supported use cases may be increased by integrating third-party technologies with Azure Migrate flexible architecture. It offers the following:
- Range of tools: The Azure Migrate utilities include Azure Migrate: Server Migration and Azure Migrate: Discovery and Assessment. Additionally, Azure Migrate interfaces with other Azure tools and services as well as solutions from independent software vendors (ISVs).
- Unified migration platform: A solo gateway to launch, manage, and monitor your Azure migration.
- Assessment, migration, and modernization: Azure Migrate hub can be used for assessing, migrating, and modernizing.
- Servers, databases, and web apps:
Web apps and SQL Server instances on local servers may be evaluated and moved to the Azure virtual machine or the Azure VMware solution. - Web applications:
Evaluation and migration of on-premises web apps to Azure App Service and Azure Kubernetes Service. - Databases: Analyze existing on-premises SQL Server instances and databases to migrate them to Azure SQL Managed Instances, Azure SQL Databases, or SQL Server on an Azure VM.
- Virtual desktops: Evaluation and migration of on-premises web apps to Azure App Service and Azure Kubernetes Service.
- Data: Utilize Azure Data Box products to swiftly and affordably migrate huge amounts of data to Azure.
- Servers, databases, and web apps:
Azure Data Migration Services
Several PaaS and IaaS alternatives are available on Azure to host your databases. By evaluating existing databases, suggesting corrections as needed, and permitting the migration, Azure Data Migration Assistant (DMA) and Azure Database Migration Service (DMS) provide help throughout this process.
What is Azure Data Migration Assistant(DMA)?
By thoroughly examining on-premises SQL instances and determining whether they are compatible with a new version of SQL Server in Azure, the Azure SQL Database service, or Azure SQL Managed Instances, DMA help in the migration process. The DMA performs a migration assessment to find any potential migration roadblocks as well as features that are partially supported or unsupported that may have an impact on the migration plan.
What is Azure Database Migration Service(DMS)?
Customers can use DMS to migrate workloads from various database source environments to Azure Data platform target services after DMA has completed the assessment.
Either an offline or an online migration can take place. During the offline migration, the application is unavailable. Online, the downtime duration is kept to a minimum during the transition period to the new environment. Due to minimal downtime, Online migration is considered a better option.
SQL Server Migration Assistant(SSMA)
Customers using multiple database platforms can use SQL Server Migration Assistant (SSMA) to move their data to SQL Server or Azure Synapse Analytics. Databases from Microsoft Access, MySQL, Oracle, SAP ASE, and DB2 are among the supported source systems.
Azure Synapse Pathway
One of the main roadblocks in modernizing a data warehouse is adapting current SQL code to a new platform. It might take a lot of time and money to translate a database because it may contain thousands of lines of code that were created over many years. This issue is addressed by Azure Synapse Pathway, which enables the migration of current data warehouses to Azure Synapse Analytics through automated code translation.
Azure Synapse Pathway can automatically transform Data Definition Language (DDL) and Data Manipulation Language (DML) commands into T-SQL-compliant language, making them compatible with Azure Synapse SQL as a target for migration. The service is presently in preview and is supported by IBM Netezza, Microsoft SQL Server, and Snowflake as source environments.
Azure Backup and Site Recovery
Data may be backed up from a variety of sources, including on-premises servers, Azure VMs, managed disks, Azure file shares and more using Azure Backup, a cloud-based backup solution. By restoring the backup data to the targeted environment in Azure, you can use the service for data migration purposes. Application consistency is integrated into Azure Backup for enterprise programs like SQL Server, Exchange, and Sharepoint. Because of this consistency, it is possible to deploy a working environment with the restored data without requiring any additional costs.
Data replication from on-premises or other cloud environments to Azure is possible via a cloud-based disaster recovery technique known as Azure Site Recovery. Although the main goal of this service is to make Azure a DR site for your workloads, it can also be used to replicate workloads and failover environments to Azure. To guarantee application integrity during failover, the service additionally employs an application-consistent snapshot-based replication approach.

Final Words
Why should one Migrate to Azure?
Virtual machines, web servers, storage, and other integrated services work well on Azure. As compared to traditional on-premises infrastructure, it is entirely cloud-based, which has benefits like quicker maintenance and you are only paying for what you use. Also, Security, Step by Step Migration, Reliability, and Scalability are a few of the main reasons you should choose Azure.
