What is the difference between a cloud server and a VPS ?

1. Performance differences:

The ECS is four times the computing power of an independent server with the same configuration, which can meet the requirements of high-performance computing.

The computing power of a VPS virtual server is only a part of a dedicated server.

2. Convenience difference:

3. Reliability difference:

ECSs are cluster-based, so the hardware redundancy is high and the failure rate is low.

VPS virtual servers have less hardware redundancy and a higher failure rate.

4. Technical differences:

Cloud servers use cloud computing technology, which integrates various software and hardware technologies such as computing, networking, and storage.

VPS virtual server simply uses virtualization software technology, which is more suitable for low-end needs than the high standard of cloud computing technology.

Let's talk about web hosting first (Yimai Cloud CDN, the lowest in the country).

Virtual hosting, also known as shared hosting, is the use of virtual technology to divide a complete server into several hosts, with multiple **, sharing the hardware and bandwidth resources of the server. Simple static and dynamic ones can be hosted to meet the most basic web hosting needs of customers.

Generally speaking, if an independent individual wants to have a personal form of **, they will use web hosting; It's a bit low, it's a few hundred dollars a year.

The disadvantage is that it is unstable, and because it is a shared IP, if there is a problem with your ** under the same IP, then your ** will definitely be affected.

In addition, VPS VPS is to divide a physical server into multiple virtual dedicated servers, and each VPS host is assigned an independent operating system, an independent IP address and an independent application, and has all the permissions of the system.

Generally speaking, small and medium-sized enterprises prefer VPS, and the biggest advantage of VPS is balance, which is suitable for users who have technical resources to maintain and want to be moderate.

Let's talk about cloud hosts.

Cloud virtual machine is based on cluster server, each host in the cluster has a mirror of the virtual machine, which can improve the security and stability of the virtual host, and compared with the virtual host, the cloud virtual machine has higher flexibility, and users can define the server configuration independently.

Cloud hosts, theoretically have unlimited scalability, CPU, memory, bandwidth, disk, can be expanded at any time as needed, and the expansion does not need to force the application offline, which is the so-called (hot expansion), which is not provided by ordinary VPS.

Finally, the cloud server:

Cloud servers, there are two other names:

One is a cloud computing server.

As for the other one, guess what?

Can't guess? Haha, another name is: cloud hosting.

That's right, in essence, cloud servers and cloud hosts are the same.

Users can customize the configuration, purchase on demand, all have root permissions, built-in KVM, users can be centrally and uniformly managed through the server, with the ability to prevent attacks, built-in APP prevention, built-in HA, can make data backup and recovery quickly.

It can be expanded at any time as needed, and the expansion does not need to force the application offline, which is the so-called (hot expansion), which is not provided by virtual hosts and VPS.

Cloud server, also known as cloud computing server or cloud host, is a host product in the cloud computing service system. A cloud server is a virtualization technology similar to a VPS server. It can also be understood as an upgraded version of VPS, which is also different from VPS in that it is divided into multiple independent host-like parts on a set of cluster servers.

Cloud web hosting, is a step from the cloud server division, through the virtual host management software, the cloud server is divided into 100m200m and other models of small space, is the best choice for small and medium-sized enterprises to build a website! Cloud servers and virtual hosts integrate high-performance servers and high-quality network bandwidth through cloud computing, which effectively solves the shortcomings of high car hosting and uneven service quality. Unlike cloud hosts, cloud virtual hosts run on each member node server of the server cluster at the same time, that is, a single site can be found on each node server, and the configuration and data of the same site on different node servers are consistent, see Kwai Fang IDC for details
