Migration to Alibaba Cloud for Government-Alibaba Gov Cloud-阿里云帮助中心

Alibaba Cloud for Government provides a secure, compliant, and dedicated cloud platform for government organizations. As an increasing number of government organizations deploy and migrate their business systems to this platform, Alibaba Cloud for Government offers professional tools, expert services, and guides to help them seamlessly migrate to the cloud.

Migration requirements

When government organizations migrate their systems to Alibaba Cloud for Government, they typically have requirements for storage, backup, disaster recovery, networking, firewalls, and IDS. After the migration, business systems must transition quickly to the new platform and operate reliably. These migration requirements fall into three types:

Data migration
Data can be classified as structured or unstructured.
- Structured data migration: This typically involves database migration. You must consider the underlying platform, as data transformation may be required before import.
- Unstructured data migration: This often involves migrating files such as videos and photos. You can migrate unstructured data online after establishing a suitable storage architecture in the cloud.
In addition, the volume of data is a key factor. For petabyte-scale datasets, online migration can be time-consuming. In such cases, offline migration is a more suitable option. Products like Lightning Cube are designed for offline migration of large data volumes.
Application migration
If your business relies on specific software with a simple stack and minimal platform dependencies, application migration is a good option. There are two methods for application migration:
- Virtualization (custom image): You can migrate the application's virtualization package to the cloud and deploy it directly on the cloud operating system (OS). This method requires that the cloud OS supports application virtualization.
- Application reinstallation: You can reinstall and configure the application directly in the cloud. The basic process is as follows:
  1. Upload: Upload the software to the cloud platform.
  2. Deploy: Deploy the software to each virtual machine.
  3. Install: Perform a batch installation.
  4. Configure: Configure the software settings.
System migration
When a business is complex and has long software dependency chains, system migration is the most appropriate approach. This method involves migrating the entire system to the cloud. After adapting underlying components like networking and storage, the business-layer software can operate with minimal changes. This is a common migration method and a primary function of Alibaba Cloud's migration tools. System migration has two approaches: online migration and offline migration.
- Online migration: An online migration involves migrating a point-in-time snapshot of your system to Alibaba Cloud for Government while the source system continues to run. The advantage is that your business services do not need to shut down, and you can launch a replica in the cloud after the migration is complete. This process does not require a separate client. The disadvantage is that the migration process may consume the computing resources of your active services, especially network bandwidth, which requires precise calculation and repeated testing. In addition, the active source system continuously generates new data, making a single-pass migration difficult. However, this is one of the easiest and safest methods to implement. We recommend this approach for system migration.
- Offline migration: An offline migration requires a complete shutdown of your business services, keeping the machine powered off. You create an image or snapshot of the physical machine or virtual machine environment and then import it into Alibaba Cloud. The advantage of this method is that it guarantees complete data integrity, and the migration client does not need to handle complex system adaptations. The disadvantage is that the migration client must be compatible with Alibaba Cloud's virtualization environment.

General migration process

A typical migration follows this process:

Analyze: Assess your applications, storage, and databases to understand the migration benefits and risks. Develop a preliminary business migration plan.
Design: Select the appropriate migration strategy. Design the cloud architecture based on your business requirements, and validate the plan for a smooth and efficient migration of typical applications.
Implement: Set up the cloud infrastructure, including configuring cloud products, network access, and security policies. Then, batch-migrate your data and applications.
Optimize: Use Alibaba Cloud's platform and tools to manage your applications. Continuously improve and optimize the architecture based on business needs and operational data.

Migration scenarios involve business architectures and cutover plans of varying complexity, which makes a manual or 'one-click' approach difficult. To address this, Alibaba Cloud for Government provides a wide range of migration tools, expert services, and guides to help government customers migrate to the cloud faster and more easily.
