Azure supports real-time migration of infrastructure, applications, and data using Azure Migrate
Azure also supports asynchronous migration of data using Azure Data Box.

Azure Migrate

Azure Migrate is a service that helps you migrate from an on-premises environment to the cloud.
Azure Migrate functions as a hub to help you manage the assessment and migration of your on-premises datacenter to Azure.
Provides a Unified migration platform: A single portal to start, run, and track your migration to Azure. Azure Migrate also integrates with other Azure services and tools, and with independent software vendor (ISV) offerings.
Provides a Range of tools: A range of tools for assessment and migration.

Azure Migrate hub also includes the following tools to help with migration:

Azure Migrate - Discovery and assessment: Discover and assess on-premises servers running on VMware, Hyper-V, and physical servers.
Azure Migrate - Server Migration: Migrate VMware VMs, Hyper-V VMs, physical servers, other virtualized servers, and public cloud VMs to Azure.
Data Migration Assistant:
- Data Migration Assistant is a stand-alone tool to assess SQL Servers.
- It helps pinpoint potential problems blocking migration.
- It identifies unsupported features, new features that can benefit you after migration, and the right path for database migration.
Azure Database Migration Service: Migrate on-premises databases to Azure VMs running SQL Server, Azure SQL Database, or SQL Managed Instances.
App Service Migration assistant: Azure App Service Migration Assistant is a standalone tool to assess on-premises websites for migration to Azure App Service.
Azure Data Box: Use Azure Data Box products to move large amounts of offline data to Azure.

Azure Data Box is a physical migration service that helps transfer large amounts of data in a quick, inexpensive, and reliable way.

Onetime migration - when a large amount of on-premises data is moved to Azure.
Moving a media library from offline tapes into Azure to create an online media library.
Migrating your VM farm, SQL server, and applications to Azure.
Moving historical data to Azure for in-depth analysis and reporting using HDInsight.
Initial bulk transfer - when an initial bulk transfer is done using Data Box (seed) followed by incremental transfers over the network.
Periodic uploads - when large amount of data is generated periodically and needs to be moved to Azure.

Disaster recovery - when a copy of the data from Azure is restored to an on-premises network.
Security requirements - when you need to be able to export data out of Azure due to government or security requirements.
Migrate back to on-premises or to another cloud service provider - when you want to move all the data back to on-premises, or to another cloud service provider, export data via Data Box to migrate the workloads.
