Cloud Migration Hub (CMH) is a one-stop migration platform that automates system surveys, cloud planning, and migration management to simplify and accelerate cloud migration.
Overview
Cloud Migration Hub (CMH) is a one-stop migration platform developed by Alibaba Cloud. It automates system surveys, cloud planning, and migration management to simplify cloud migration and help you manage the full migration lifecycle.
Benefits
Adaptation to various sources
CMH supports various IT infrastructures, including on-premises data centers and cloud platforms such as AWS, Azure, and Tencent Cloud. Purpose-built collectors gather resource information such as networking, hostnames, processes, topologies, and performance for migration analysis and planning.
High data security
CMH supports both automatic and manual data import to meet different data security and auditing requirements. All IT resource information, including IP addresses, hostnames, processes, monitoring data, and networking, is encrypted with Alibaba Cloud Key Management Service (KMS) before being stored on disks.
Full lifecycle management
CMH provides best-practice migration plan templates for various scenarios. End-to-end tools help you survey resources, map service specifications, create resources, create and schedule migration tasks, and monitor migration status on a dashboard.
Ease of use and high efficiency
CMH integrates multiple Alibaba Cloud migration services in a centralized console. A built-in task scheduling feature lets you batch schedule migration tasks by creating scheduling groups.
Migration plan templates
CMH provides built-in migration plan templates based on best practices. Use these templates to create migration plans for various scenarios and obtain recommended resource specifications and migration tools.
Infrastructures as code
CMH intelligently maps source instances to Alibaba Cloud resources based on your migration plan scenario and generates executable Terraform code for batch resource management.
Solution and tool recommendation
CMH provides pre-configured migration tools and plan templates for various scenarios. It supports source-destination mapping and batch migration task creation.
Migration efficiency improvement
CMH provides components to improve migration efficiency and stability when migrating resources to Alibaba Cloud in batches.
Task Management > Batch Task Group
On the page of the CMH console, create multiple migration tasks at a time by configuring parameters or uploading templates. This reduces repeated manual operations.
Task Scheduling
The Task Scheduling page lets you configure scheduling policies to manage migration tasks by scheduling group and time period. You can configure custom conditions in scheduling policies. This resolves issues such as insufficient migration bandwidth and source-end overloading during batch data migration.
The figure shows enabled scheduling groups on the Task Scheduling page.
Traffic playback
Scenarios of traffic playback
Database migration can be difficult 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 resolves these issues by running the system SQL logs of your source database on the destination database. This exposes database transformation focus areas and performance issues, reduces the difficulty of database migration, and provides an agile and transparent migration testing experience.
Core capabilities of traffic playback
-
Database log collection: Collects audit logs and SQL logs of various database services and parses them into playback logs in a unified format.
-
Traffic playback: Reads playback logs and replays them in different database services.
-
Task management and playback result viewing: Centrally manage playback tasks and view playback results.
Scenarios
Migration caused by the replacement of cloud service providers
When migrating from a third-party cloud provider to Alibaba Cloud, CMH automates resource surveys, helps build migration plans, and synchronizes migration task status across Alibaba Cloud migration services for centralized monitoring.
Cloud migration for traditional enterprises
Traditional enterprises with multiple coupled application systems across departments have high requirements for data security and auditing. CMH provides various survey methods covering most IT infrastructures, supports data export and auditing, and centrally displays migration task progress.
Big data migration to cloud and data mid-end building
CMH provides tools to survey on-premises resources, perform model-based analysis, and configure multiple migration tasks at a time for building cloud-based data warehouses and data mid-ends. This enables secure, efficient, and visualized data migration to Alibaba Cloud.
Data migration for disaster recovery and data center building
CMH efficiently discovers resources at your source data center and provides business-oriented solutions for migration and synchronization between data centers, supporting disaster recovery and multi-data-center deployments.
