How to migrate the data center to the cloud platform

Analyzing the environment can help enterprises sort out the underutilized assets. It is necessary to know which applications support virtualization and classify them on this basis. Classification standards: different standards such as platform-based, whether middleware is needed, and database-based classification. Testing and evaluating the environment can help enterprises find out exactly which applications may not support virtualization. Generally speaking, enterprise applications need high CPU power and large databases, and it is not recommended to move to a virtualized environment.

2. Consolidate and virtualize servers.

Server requirements change frequently in order to achieve overall analysis, including usage patterns, and to determine computing power before performing migration from physical machines to virtual machines. Analyze the computing requirements during peak hours or upgrades, which will affect performance and management. Servers need to be separated and combined. If there are applications running in two databases, you must use a middleware server or SQL server running multiple databases. After integrating the architecture, we should test the environment to avoid any network and storage failures, and then we can start virtualization.

3. Network and storage virtualization

Analyze the network and storage architecture to find out possible performance problems. For separated and isolated networks, we can use virtual local area network configuration and separate the traffic of our products from other traffic to ensure proper bandwidth utilization. In terms of storage, the most important thing is scalability. The main problem of capacity planning and management is to analyze storage usage patterns. Enterprises should test storage to ensure that they can manage hypervisor load and support virtualization. Enterprises should also observe automatic storage management, which can arrange storage resources in multi-tenant or air architecture and realize storage sharing in different applications.

4. Move to the cloud

The migration of architecture to cloud also needs to be done step by step. Initially, some key applications and related architectures can be migrated less. Business-critical architecture should be based on previous successful steps. Ensure that the environment of the physical product has been removed, but do not completely retire. In case of any accident, the physical product environment can be reused. You must preserve the physical environment and run applications and servers that cannot be virtualized. We should ensure that service providers meet industry standards. Strict service level agreements (SLA) and standardized reports are essential, and strict access control is recommended at all levels.
