Quick question and quick answer - FAQ of Tencent Cloud Server

What is a CVM instance:

Cloud Virtual Machine (CVM) provides you with secure and reliable elastic computing services.In just a few minutes, you can acquire and enable CVM in the cloud to meet your computing needs, and you can scale up or down computing resources in real time.Each instance type provides different computing and storage capabilities, and users can choose the instance computing capabilities, storage space, and network access methods based on the scale of services to be provided.

Which operating systems does Tencent Cloud Server support?

Tencent Cloud Server CVM currently supports Windows Server, CentOS, CoreOS, Debian, FreeBSD, OpenSUSE, SUSE, and Ubuntu operating systems.In addition, we will continue to work hard to expand more platforms.

Why do I need real-name authentication when using?

According to the requirements of the Ministry of Industry and Information Technology's 2017 comprehensive domain name real-name certification, all existing domain names and newly registered domain names must undergo real-name certification. If your domain name fails to pass the real-name review within the specified time, the registry will suspend the resolution and cannot access it normally.After the real-name authentication is passed, normal use can be resumed.

What is the difference between the external network IP and the internal network IP of the cloud server

Intranet IP: Also known as private IP address, it is the connection address that provides services for clients whose source IP is the private network.

External network IP: Also known as the public IP address, it is the connection address of the client whose source IP is the public network for public network communication.

They can be directly mapped to each other through network address translation.Servers in the same region can communicate through the intranet; servers in different regions can only communicate through the public network.

What is an Elastic IP?

Elastic public IP address is a static IP address specially designed for dynamic cloud computing.It is the next fixed public IP address in a certain region.With an elastic public IP address, you can quickly remap the address to another CVM instance (or NAT gateway instance) in your account, shielding you from instance failure.

What is mirror sharing?

Shared image is to share the custom image that you have created to other users.Users can easily obtain shared images from other users, and obtain required components and add custom content from them.Each image can be shared with up to 50 users.Shared mirrors do not occupy their own mirror quotas.
