Azure Migration is a process of moving your on-premises or other cloud provider workloads to the Azure cloud. Microsoft provides several tools and services to assist with the migration process. 

Here are some key Azure migration services:

Azure Migrate: Azure Migrate provides a centralized hub to assess and migrate to Azure on-premises servers, infrastructure, applications, and data. It provides tools to discover, assess, and migrate your on-premises applications, infrastructure, and data to Azure.

Azure Site Recovery (ASR): ASR contributes to your disaster recovery strategy by orchestrating replication, failover, and recovery of workloads and apps so that they are available from a secondary location if the primary location fails. It can also be used for migrating VMs to Azure.

Azure Database Migration Service (DMS): Azure DMS is a fully managed service designed to enable seamless migrations from multiple database sources to Azure data platforms with minimal downtime.

Azure Data Box: Azure Data Box family products help you to move large amounts of data to Azure when the network isn't an option. You can use them for offline data transfer, or as a temporary storage solution.

Azure App Service Migration Assistant: A tool that can be used to migrate sites from on-premises to Azure App Service. It supports migration of .NET and PHP web applications.

Azure DevOps: Azure DevOps can be used to re-architect an application to a cloud-native architecture and then deploy it using CI/CD pipelines.

These services provide a comprehensive solution for migrating your applications, infrastructure, and data to Azure, helping you take advantage of the scalability, flexibility, and cost benefits of the cloud.
