CVM is a simple, efficient, secure and reliable computing service with flexible processing capacity. Its management is simpler and more efficient than physical servers. Users can quickly create or release any number of CVMs without purchasing hardware in advance.

CVM helps you quickly build more stable and secure applications, reducing the difficulty of developing OPS and the overall IT cost, so that you can focus more on the innovation of your core business.

Cloud computing servers (also known as cloud servers or cloud hosts) mainly provide Internet-based infrastructure services for small and medium-sized enterprise users and high-end users. This user group is large, and the demand for Internet host applications is increasing. The user group has the following characteristics: the business is mainly host rental and virtual dedicated server, some of them use hosting service, and the scale is large; pay attention to the short-term return on investment, and have high performance-to-price ratio of products; personalized demand is strong, tend to the whole value chain, stupid products. When using traditional servers, users have to face a variety of thorny problems because of cost, operator choice and many other factors, and the introduction of flexible cloud computing servers effectively solves this problem.

What is a CVM?

Cloud computing server (also known as cloud server or cloud host) is a host product in the cloud computing service system, which effectively solves the shortcomings of difficult management and weak business scalability in the traditional physical host and VPS services. In practical applications, CVMs have three aspects of flexibility:

Host service configuration and business scale can be configured according to the needs of users, and can be flexibly adjusted. The host services applied by users can be quickly supplied and deployed (real-time online activation), which enables flexible and scalable billing methods in the cluster, users do not need to pay deposits, and there are a variety of payment methods for users to choose from.

What kind of users are CVM suitable for?

Users who pay attention to the performance-to-price ratio of host services; users who need to quickly achieve distributed deployment; users who need flexible expansion of business; users who need high availability and rapid recovery of the system; users who want to easily manage the system. Support Internet applications such as e-commerce, forums, SNS, corporate websites, OA systems, etc.

What are the main advantages of cloud servers over VPS?

Users can easily carry out remote maintenance, free reinstallation of the system hardware level to achieve complete isolation between CVMs; built-in redundant shared storage and intelligent backup, physical server failure can be automatically recovered within minutes; the service environment uses high-end servers for deployment, while centralized management and monitoring are adopted to ensure the stability and reliability of the business. Stronger host performance, the overall performance is much higher than VPS, better than some stand-alone servers

What are the main advantages of a cloud server over renting a physical server?

The rental price of CVM is lower than that of traditional physical servers, and there is no need to pay a deposit. With rapid supply and deployment capability, users can activate the CVM in real time and get the service immediately after submitting a CVM rental application. The service supports smooth expansion, and when the user business scale expands, the service expansion can be realized quickly.

Can I apply for multiple IP on CVM?

The CVM will be equipped with a different number of IP addresses depending on the line selected by the user. One independent IP is provided by default for single line, and two independent IP for dual lines. The bandwidth cannot be limited due to the increase of IP, so IP is not added for the time being.

Does the CVM lease the product to send the property right?

No property rights. CVM is a host product based on cloud computing platform, and users actually pay for the computing, storage capacity and high-quality network bandwidth of cloud computing platform. Users only have to pay for the resources actually used, which is one of the main factors that users can significantly reduce costs by choosing a cloud host.

Can the user choose to install the operating system?

Sure. There is no obvious difference between the product use form of the CVM and the traditional physical server, and users can flexibly choose or change the operating system according to their own needs.

If you want to buy and open, how long will it take? How long will it take to expand?

Register users-> online payment-> purchase CVM and activate it in real time. Log in to the → CVM in the user management area to manage the → management → pre-installed operating system after activation. You can choose operating systems such as Windows 2008, Windows 2012, Cent OS 6.5.It takes 10 minutes to install the system. After the system installation is completed, you can perform other application operations through remote connection.

Do I need to pay a deposit to rent a CVM?

Unlike traditional physical server leasing, CVM leasing users do not need to pay a deposit to enjoy the service.

How can I view the configuration of a leased host?

Because the use of a CVM is similar to that of a physical server, users can view the configuration information of the server and the current resource usage in real time in the operating system.

Can the backup disk be used to store my files?

Backup disk is used for system intelligent backup service, which is mainly used in disaster recovery.

How many CPU are there in the service manager?

After installing the operating system, you must restart the CVM to see multiple CPU, except if only one CPU is purchased.
