What I want to share with you in this article is about whether the migration of CVM is reliable. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

If the application exists in the cloud server cloud platform and needs to be moved flexibly to other platforms, it may mean that some of the tools and features of the original platform cannot be used. Users need to carefully consider cloud migration plans, and in order for cloud migration plans to be implemented, enterprises should consider portability when designing cloud deployments.

When formulating a CVM migration plan, enterprises need to consider the following:

(1) Workflow. The enterprise needs to understand the workflow of the application. If the input or output is associated with another application or business process running on the same cloud platform, there may be problems in migrating the business to another provider's cloud host.

(2) workload. Whether cloud computing providers optimize or build their platforms around the needs of workloads. For example, government applications may be easier to run on cloud platforms that are specifically designed to meet organizational security and accessibility requirements.

(3) Application and language. In some cases, such as infrastructure as a service, you can control the operating system, middleware, and runtime libraries. In platform as a service, this control will be lost, and cloud computing providers will determine many of these areas. This approach can limit application and language support.

(4) tools. A cloud migration plan from one cloud platform to another means that users' applications may be rewritten or third-party features integrated into the original service offering may be added. The better the toolset provided by cloud computing providers, the higher customer loyalty will be.

(5) networking. The network is an important part of cloud computing applications, especially those that must communicate with internally deployed applications or applications that may be moved back to the user's data center. Enterprises that migrate applications to cloud platforms must maintain two network stacks: one for their internal deployment and the other for cloud-based deployments.

(6) data structure. The data structure is very dependent on the application. However, the data structure has become a complex problem of actual migration. At this point, it may take hours to debug applications that are not running as expected. This failure may be caused by some problems with the data structure itself, which can prevent the application leased by the cloud host from running as expected.

(7) Storage. A key consideration in the cloud migration plan is cloud storage. Enterprises need to consider the cost and how to keep the data. In addition, you need to consider how to migrate data from an existing application to a new application hosted by another provider. Most cloud computing providers can easily, economically, and efficiently import data into cloud platforms.

The above is whether the migration of CVM is reliable. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
