This topic describes introduces Cloud Migration Hub, including its concept, workflow, benefits, key features, and scenarios.
Concept
Cloud Migration Hub is a one-stop migration platform developed by Alibaba Cloud. It provides automated and intelligent system surveys, cloud planning, and migration management to simplify and accelerate cloud migration. This helps you manage the full lifecycle of migration in a business-oriented manner.
Benefits
Adaptation to various sources
Cloud Migration Hub adapts to various common IT infrastructures in different environments, including general data centers and cloud platforms such as Amazon Web Services (AWS), Azure, and Tencent Cloud. The migration team of Alibaba Cloud designs specific collectors to survey resources in different environments. The collectors can collect resource information such as networking, hostnames, processes, topologies, and performance. The collected data is used for subsequent migration analysis and planning.
High data security
To meet different requirements on data security and auditing, Cloud Migration Hub supports automatic import of collected data, and also allows you to export collected data from on-premises computers, check the data, and import the data to Cloud Migration Hub. In addition, Cloud Migration Hub provides full-process encryption for all IT resource information. The IT resource information is encrypted by using Alibaba Cloud Key Management Service (KMS) before it is stored on disks. This ensures high data security. The IT resource information includes all the information collected by Cloud Migration Hub and all the data that you import, such as IP addresses, hostnames, processes, monitoring data, and networking.
Full lifecycle management
Cloud Migration Hub provides migration plan templates that are generated based on best practices. You can create migration plans with the templates for various migration scenarios. Cloud Migration Hub also provides a variety of end-to-end tools to help you survey resources, map service specifications, create resources, create migration tasks, schedule tasks, and monitor migration status on a dashboard. You can use the migration plan feature to manage the full lifecycle of migration.
Ease of use and high efficiency
Cloud Migration Hub provides one-stop migration capabilities to improve cloud migration efficiency. It integrates with multiple Alibaba Cloud migration services and allows you to manage these services in a centralized manner. You can quickly and flexibly initiate migration tasks. In addition, a built-in lightweight task scheduling feature is provided to batch schedule migration tasks by creating scheduling groups.
Migration plan templates
Cloud Migration Hub provides built-in migration plan templates that are generated based on best practices. You can create migration plans with the templates for various migration scenarios and obtain the resource specifications and migration tools recommended by Cloud Migration Hub.
Infrastructures as code
To help you manage infrastructures efficiently and visually, Cloud Migration Hub intelligently maps source instances to Alibaba Cloud service resources of specified specifications based on the scenario of your migration plan. It also automatically generates executable Terraform code for batch resource management.
Solution and tool recommendation
Cloud Migration Hub provides pre-configured migration tools and migration plan templates for various migration scenarios to lower the barrier to cloud migration. It also supports source-destination mapping and allows you to initiate migration tasks in batches.
Migration efficiency improvement
Cloud Migration Hub is designed for you to migrate all your resources to Alibaba Cloud in batches. It provides a series of components to improve migration efficiency and stability.
Task Management > Batch Task Group
Cloud Migration Hub provides the batch task management feature to help you initiate migration tasks more quickly and flexibly. You can go to the page of the Cloud Migration Hub console to create multiple migration tasks at a time by configuring parameters on the page or uploading templates. This greatly reduces repeated manual operations.
Task Scheduling
Cloud Migration Hub provides the task scheduling feature to resolve issues such as insufficient migration bandwidth and source-end overloading during batch data migration. You can go to the Task Scheduling page of the Cloud Migration Hub console to configure scheduling policies to manage migration tasks by scheduling group and time period. You can configure custom conditions in scheduling policies.

The preceding figure shows the scheduling groups that are enabled on the Task Scheduling page.
Traffic playback
Scenarios of traffic playback
Database migration can be difficult to implement, due to reasons such as a lack of migration experience, concern about incompatibility with destination databases, and concern about the insufficient performance of destination databases.
The traffic playback feature provides a solution to resolve the preceding compatibility and performance issues. You can perform a migration test to run the system SQL logs of your source database on the destination database. This exposes the focus areas of database transformation and the performance issue, reduces the difficulty of database migration, and provides users with an agile, efficient, and transparent database migration experience.
Core capabilities of traffic playback
Database log collection: The traffic playback feature collects the audit logs and SQL logs of various database services and parses the collected logs into playback logs in a unified format.
Traffic playback: The traffic playback feature reads playback logs and plays back the logs in different database services.
Task management and playback result viewing: You can centrally manage playback tasks based on your playback schedule and view the playback results.
Scenarios
Migration caused by the replacement of cloud service providers
You may want to migrate some or all of your resources from a third-party cloud service provider to Alibaba Cloud if the cloud service provider cannot meet your requirements or if you require multi-cloud deployment. Cloud Migration Hub supports automated surveys on resources in third-party clouds and can help you build migration plans. It also synchronizes the status of migration tasks that you create by using other Alibaba Cloud migration services. This way, you can check the status of migration tasks in a centralized manner.
Cloud migration for traditional enterprises
Traditional enterprises usually have multiple application systems and closely coupled applications. The application systems are typically managed by different departments. In addition, traditional enterprises often have high requirements for data security and auditing. Cloud Migration Hub provides different types of survey methods that cover most IT infrastructures and allows you to export and audit data. You can further design the architecture of your business on Alibaba Cloud based on the survey results. Cloud Migration Hub centrally displays the progress of migration tasks.
Big data migration to cloud and data mid-end building
You may want to migrate on-premises data to Alibaba Cloud to build cloud-based data warehouses and data mid-ends. Cloud Migration Hub provides tools to help you quickly create tasks to migrate a large amount of data. You can use the tools to survey your on-premises resources, perform model-based analysis, configure multiple migration tasks at a time, and manage migration tasks in a centralized manner. This way, your data can be migrated to Alibaba Cloud in a secure, efficient, and visualized manner.
Data migration for disaster recovery and data center building
To meet the requirements for disaster recovery based on multiple data centers, you may want to replicate data from one data center to another. Cloud Migration Hub can efficiently discover the resources at your source data center and provide business-oriented solutions for migration and synchronization between the two data centers. This way, you can build a data center in an efficient, fast, manageable, and monitorable manner.
