ElasticComputeService (ECS) is a computing service with flexible processing capacity, and its management mode is simpler and more efficient than physical servers. CVM helps you quickly build more stable and secure applications, reduces the difficulty of developing OPS and the overall IT cost, and enables you to focus more on core business innovation. However, we still need to pay attention to some considerations of the CVM to ensure that you can fully enjoy these advantages. Here, the Cloud gives you a brief introduction to the 6 most common problems when ordering a CVM for the first time.

Lack of clear business objectives and deployment plans

Since the CVM supports matching resources such as CPU, memory, storage and bandwidth on demand, and it can be easily set up using the console, it seems easy to start with. However, you may miss out on some important advantages of the cloud platform. Therefore, after selecting a CVM, you need to take some time to communicate with the cloud provider to get a more comprehensive understanding of which cloud model is most suitable for your business deployment and development, such as a separate cloud server, or a complete IaaS environment and which operating system. Also, you should consider indirect costs such as after-sales technical support, business migration, and refactoring.

2. Not all CVMs are the same.

As the cloud computing market becomes more and more commoditized, it's easy to get the illusion that every provider's cloud servers seem to be the same. In fact, CVM providers may vary greatly in terms of technical support, redundancy, network connection speed, security, and so on (the importance of these factors depends on your cloud environment needs and needs). For example, Zhiyun is a cloud computing platform independently developed based on the OpenStack architecture, while other cloud server providers provide different cloud computing platforms. The underlying, network, cluster and other architectures are different, and the performance and performance are also very different. Moreover, at present, there are still cases in the domestic market that VPS is sold as a cloud server.

Third, ignore the hidden and indirect costs of CVM

Improving cost efficiency may be one of the important driving forces for you to migrate some or all of your IT workloads to CVM. In essence, the cloud server is the massive hardware physical server cluster to form a cloud virtual resource pool, the utilization of resources is greatly improved, and the cost is reduced.

However, in spite of this, you should also be aware of the hidden and indirect costs of the cloud server, such as the cost of business migration to the cloud server, the cost of technical services, the cost of application refactoring, and so on.

4. Lack of necessary skills and knowledge of CVM management

Knowledge and skill requirements are the key to success. To ensure that your cloud server deployment gives you the best results, you may need additional skills and expertise. Depending on your specific situation, this may mean that you need to choose a cloud server vendor that can provide any additional support, or you may need to invest in internal team training or even hire new employees.

In fact, your knowledge of CVM operation and maintenance may help you decide which type of cloud deployment you will ultimately choose, such as fully hosted cloud servers, self-built virtual data centers, or hybrid cloud computing.

Fifth, generate dependence

When using a cloud server, you should be as flexible as possible. When you customize more and more complex cloud management tools from a cloud server provider, you may inevitably rely on these tools, which will make it difficult for you to adapt and change when you need to change cloud service providers in the future.

An overconfigured platform can lead to a trap environment that makes it difficult to support new applications. In addition, there may be problems when trying to create an environment for future migration projects due to incompatibility with a wider range of interfaces.

VI. Insufficient testing

By thoroughly testing your cloud environment before going live, you can avoid unnecessary interference and business disruption. In addition to methodically testing the cloud environment, you can also test the after-sales technical support process of the cloud server provider so that you can get help through open channels as soon as you encounter problems in the future.
