At present, cloud computing has become a hotspot in the development of cloud technology. With the development of cloud computing, Huawei Virtual machine The application of cloud computing is also becoming more and more popular. But some users are using Huawei Virtual machine In the process of Huawei VM How to migrate the cloud computing environment? What should be paid attention to during migration? At present, many developers and companies are looking for a cloud server suitable for their business What should we pay attention to when using Huawei VM to migrate the environment? Micronet recommends Huawei VM, but we should also pay attention to the following issues. 1. Keep in mind the basic knowledge of Huawei VM migration cloud environment
Remember the basic knowledge in the cloud computing migration process, and don't forget the basic steps in the migration process. Although the migration process has to be stopped, you can perform as many load tests as possible when the original server is still suitable. In addition, remember to correct the DNS of the domain name, and generally set the TTL to be sufficient or low. It is better to complete 3~4 times of the new DNS operation plan before migration.
2. Monitor the performance of Huawei VM
After migration, it is not only necessary to monitor the performance of the user program, but also more important to master the running status of the program before migration. When setting up a user program in the public cloud, multiple endpoints are usually displayed, so it is urgent to know the running conditions of all hosts. Huawei VM provides users with cloud monitoring services. It can even monitor users hosted internally. In addition, open source monitoring solutions like Nagios are also very good.
3. There is a complete recovery plan
If Huawei's virtual machine migration environment is not successful, you must be prepared before starting the migration. When it comes to migration failure and the need to return to the original state, everyone will feel serious and worried. However, if you fail and you don't make a choice, the situation will become worse.
4. Use the application to understand the situation
Based on past experience, you need to understand the architecture of your application and its bottlenecks. Find out the part of the runtime with the largest load, and focus on expanding this part of the function, to ensure that at each different level, your use can provide support for multiple endpoints (including networks, users, databases, etc.), so as to take advantage of the advantages of cloud computing.
5. Combined API
Huawei VM exposes its own Cloud API and encourages you to use it to run your applications. By using the program together with the huaweicloud API, calling it can actively complete various tasks. For example, when the load level of the user program is too high, it can actively extend the device layer.
6. Understand the requirements of industry and region to comply with regulations
Depending on your occupation and address, you may need to meet different compliance requirements. PCI regulates the use of e-commerce, medical use is consistent with the HIPAA regulations of the United States, and other professions and regions also have relevant regulations. However, please note that some Huawei virtual machine requests may only apply to several application device layers.
The above is Micronet's analysis of several problems in using Huawei VM to migrate the cloud computing environment. If you can pay attention to them during the migration process, your cloud computing environment migration process will be very smooth. Huawei Cloud, a micro network agent, is an excellent cloud computing service provider. It can provide the best service for friends who want to rent Huawei virtual machines to set up private game servers. It has perfect industry solutions and excellent cloud computing technology. The self-developed pure SSD architecture virtual machine breaks the industry record with 50000 IOPS random read/write speed and 800 Mb/s throughput as performance indicators. The ECS elastic virtual machine uses pure SSD architecture hardware devices. It can easily acquire and enable the cloud in just a few minutes to meet your computing needs. Expanding the flexibility of resource use also saves you computing costs, simplifies IT operations, and enables you to pay more attention to core business innovation.
