虚拟主机和云服务器功能一样么(云服务器和虚拟主机哪个好)

The difference between cloud servers and cloud virtual hosts is that cloud servers use virtualization technology to virtualize a large number of independent servers into a virtual server with distributable performance. The number of CPUs required can be freely customized. Memory size, hard disk size, bandwidth resources, IP resources, etc. The virtual host uses virtual technology to divide a server into many small spaces. Each host space uses CPU resources, memory resources, IP resources, etc. to share a server, and its performance is greatly limited by This virtualized server.

There are some differences between the two in terms of service content, performance, resource allocation and applicable users, as follows:

Service content: The cloud server provides an independent virtual machine , has its own independent operating system, independent computing resources, independent storage space, etc.; while cloud virtual host uses virtual technology to divide multiple virtual hosts on a physical server, and these virtual hosts share the same physical server. Computing resources and storage space.

Performance: Since the cloud server has more computing resources and a more independent environment, its performance is relatively stronger and more stable, and it is suitable for application scenarios that require high performance and high reliability; while cloud servers Because virtual hosts share physical server resources, there may be problems such as resource competition and performance fluctuations.

Resource allocation: Cloud servers can freely allocate computing and storage resources according to needs, with higher flexibility and scalability; while cloud virtual hosts are limited by the resources of the physical server where they are located and cannot be used on demand at any time. Increase or decrease resources, but relatively cheaper.

Applicable groups: Cloud servers are suitable for enterprises with high performance and security requirements, high-end developers and users who need to expand applications on a large scale; while cloud virtual hosts are suitable for individuals, small businesses and small and medium-sized websites and other smaller users.

When you plan to build a website, you will face the choice of whether to choose a cloud server or a virtual host for the website space. Do you understand the difference between a cloud server and a virtual host before choosing? If you don’t understand, let tell you.

What is the difference between cloud server and virtual host?

1. Resource utilization and usage rates are different. Cloud servers use virtualization technology to virtualize a large number of independent servers into a virtual server (cloud server) with allocable performance. You can freely customize the required number of CPUs, memory size, hard disk size, bandwidth resources, IP resources, etc. Virtual host uses virtual technology to divide a server into many small spaces. Each host space uses CPU resources, memory resources, IP resources, etc. to share a server, and its performance is greatly limited by the A virtualized server.

2. The usage performance is different. The cloud server will not be slow when processing a large amount of data resources. If a larger amount of data needs to be processed, the server configuration can be upgraded at any time. The Eagle Cloud Server, CPU, memory, bandwidth, hard disk, etc. can be elasticized at any time. upgrade. The virtual host is only suitable for small and medium-sized websites. Once the website data is accessed too large, the virtual host will become slow, and upgrading the virtual host is troublesome. The upgrade process requires data to be transferred to other spaces, which is very troublesome.

3. The technical requirements are different. The cloud server has a separate operating system, independent CPU, memory and other resources. Before use, the server operating system environment needs to be installed. During use, you need to pay attention to the various resources, configuration and operation of the server. For virtual hosting, the provider sets up everything, and users only need to upload website data to the space and then it can be used immediately. During use, users only need to worry about minor issues such as website access speed.

4. Differences in safety and reliability. The cloud server is based on cloud computing architecture and can automatically switch failed nodes to normal hosts. It has strong stability and built-in ARP prevention. It can improve DDoS and virus attack prevention capabilities on a large scale and provide various data recovery measures such as snapshots and mirrors. Virtual hosts are now all located on the cloud platform, and security and stability are also strong. However, due to the sharing of resources such as CPU, bandwidth or IP, the performance is still slightly inferior, and the attack resistance is not as good as that of cloud servers.

5. The difference between elasticity and scalability. The cloud server can support elastic expansion and pay on demand. When the server performance cannot meet the business development needs of the website, the user can expand the capacity at any time and upgrade the host CPU, memory, hard disk, bandwidth and other configurations to have enough business buffer space, while the virtual host Upgrading or expanding capacity is relatively troublesome and requires re-renting new space.

What is a virtual host?

Virtual hosting uses network space technology to divide a server into many "virtual" hosts. Each network space has an independent domain name and IP address, and has complete Internet server functions. Network spaces are completely independent. From the outside world, each network space is exactly the same as an independent host. The effect is the same, but the cost is very different. Since multiple cyberspaces share the resources of one real host, the hardware costs, network maintenance costs, and communication line costs borne by each cyberspace user are greatly reduced, and the Internet has truly become a network that everyone can afford.

Features of virtual hosting:

1. Low cost, suitable for novices.

2. Simple management, no need to configure the website environment, just upload the website program.

3. Shared resources and insufficient stability.

What is a cloud server?

Cloud server, also known as cloud computing server or cloud host, is a host product in the cloud computing service system. Cloud server is a virtualization technology similar to VPS server. It can also be understood as an upgraded version of VPS. It is also different from VPS in that it is divided into multiple independent host-like parts on a group of cluster servers. Each server in the cluster will have an image of the cloud host. When one of the machines breaks down. You can automatically jump to other machines for access. So in theory. As long as not all machines break down. It will not affect access to the cloud host. Therefore, cloud hosting is more powerful than VPS in terms of security and stability.

Characteristics of cloud servers:

1. Elastic expansion, configuration upgradeable, and pay-as-you-go.

2. Simple and efficient, there is no need to purchase machines in advance, it can be used immediately, and business deployment is quick.

3. Independent operating system, isolation of hardware resources + exclusive bandwidth.

4. Centralized remote management platform + multi-level business backup.

After reading the above introduction, everyone should have an understanding of the difference between cloud servers and virtual hosts. Both cloud servers and virtual hosts are sold on , and they are cheap and have high security protection levels. High, well received by all webmasters.
