The difference between cloud hosting and traditional VPS

1. From a technical point of view: cloud computing technology is used by cloud computing technology, and cloud computing technology integrates various software and hardware technologies such as computing, network, and storage. For VPS, it simply uses virtualization software technology, which is still relatively backward compared to the high standard of cloud computing technology;

2. From the perspective of security: the cloud host has natural anti-ARP attacks and MAC spoofing, snapshot backup, and data will not be lost forever. VPS, on the other hand, does not have this functionality;

3. In terms of reliability: cloud hosts are based on server clusters, so the hardware redundancy is high and the failure rate is low; VPS, on the other hand, has less hardware redundancy and a higher failure rate.

5. From the perspective of performance: the cloud host is 4 times the computing power of the same configuration of independent servers, which can be satisfied.

requirements for high-performance computing; And the computing power of VPS is only a part of the independent server;

6. From the perspective of isolation: the cloud host adopts hardware isolation, which does not affect each other at all; VPS, on the other hand, uses software isolation, which has a greater impact on each other.

Cloud hosts must be purchased from large companies to be guaranteed, such as: Times Internet.

Hello. Let me answer your question.

In fact, cloud hosting is equivalent to an upgraded version of VPS. their function. The method of operation is exactly the same.

The difference is the implementation of the technical principle. VPS is a portion of memory allocated to a physical server. Hard disk.

bandwidth. When there is a problem with this mother machine. All the VPs above will be affected.

A cloud host, on the other hand, is a group of independent host-like parts that are divided into clusters of servers. Each machine in the cluster will have an image backup of the virtual machine. And data synchronization is realized.

When one of the machines fails. The system automatically accesses backups on other machines. So in terms of security and stability.

Cloud hosting is more powerful than traditional VPS. Cloud hosting is also a trend now and in the future.

Cheap. Because services can be spread across multiple servers, resources can be fully utilized, which reduces hardware, power, and maintenance costs. Moreover, cloud hosts are billed according to usage, and they use more and pay more, and pay less and pay less, so it is especially beneficial for small **.

Scalability

The basic feature of cloud hosting is the distributed architecture, so it is easy to increase the number of servers and expand the service capacity exponentially.

Cloud hosting is also present.

Xinmai Internet elastic cloud host is developed with reference to Amazon elastic cloud, and the real cloud computing architecture is one of the few in China. Using distributed storage, 4 copies of the data of each virtual machine are retained, and they are stored on several servers in the cluster in real time, even if 3 copies of the data are damaged at the same time, it will not affect the normal use of the virtual machine! It supports hot migration and achieves more than system reliability.

Combined with 10 years of experience in host product operation, we strive to create a cloud host with high reliability, high IO, moderate, and the most easy-to-use!

There are five points for cloud hosting and VPS:

1. ** and deployment time.

VPS is instantaneous and requires no OS installation.

The cloud host is also instantaneous, can be completed in a few minutes, can be deployed with one click, or can be installed independently.

2. Safety and reliability.

Poor VPS security: Program defects, ARP spoofing, viruses, and resource crowding installed on other VPs on the same physical server will seriously affect the company. There is basically no ARP, Trojan horse, or DDoS protection capability.

High VM security: Built-in ARP protection to improve DDoS attack prevention capabilities on a large scale; Share the performance and reliability of branded enterprise-class servers and hardware virtualization, built-in HA; Provides a variety of rapid recovery measures, such as standby machines, snapshots, and data backups.

3. Performance and guarantee.

Poor VPS performance and guarantee: The performance is average, and it is only suitable for small-scale concurrent access. Performance is not guaranteed, and it is susceptible to other VPS on the same physical server.

The performance and guarantee of the cloud host are good and guaranteed; Same as a physical server.

4. Elasticity and scalability.

VPS capacity expansion is fast, which is limited by the configuration of a single server.

The cloud host is instantaneous** and expands on demand, without paying for the original leased resources.

5. Cost of ownership.

VPS with low VPS configuration is the lowest**, but low security reliability and unguaranteed performance lead to unguaranteed service quality and uncontrollable operating costs.

The lowest comprehensive cost of cloud hosts: no deposit for monthly payment, pay-as-you-go use, basic zero maintenance, and the cost advantages brought by scale, green energy saving, and best IT practices can also be shared.

First, the subject is different.

1. Cloud host: It is an important part of cloud computing in infrastructure applications, located at the bottom of the pyramid of cloud computing industry chain, and its products originate from cloud computing platforms.

2. VPS cloud host: a high-quality service that divides a server into multiple virtual exclusive servers.

Second, the principle is different.

1. Virtual machine: It is a part that virtualizes multiple independent hosts on a group of cluster hosts, and there is an image of the virtual machine on each host in the cluster, which greatly improves the security and stability of the virtual host.

2. VPS cloud host: using virtual software, VZ or VM virtualizes a number of parts similar to independent hosts on a host, which can realize multiple users on a single machine, and each part can be a separate operating system, and the management method is the same as that of the host.

Third, the characteristics are different.

1. Cloud host: IT infrastructure capacity rental service that integrates computing, storage and network resources, and can provide server rental services based on cloud computing mode for on-demand use and pay-as-you-go capabilities.

2. VPS cloud host: Each VPS host can be assigned an independent public IP address, an independent operating system, an independent large space, an independent memory, an independent CPU resource, an independent executor and an independent system configuration.

Cloud host is a virtualization technology similar to VPS host, VPS is the use of virtual software, VZ or VM on a host to virtualize a number of parts similar to independent hosts, can achieve a single machine and multiple users, each part can be a separate operating system, the management method is the same as the host. The cloud host is a part of a group of cluster hosts that virtualize a plurality of independent hosts, and each host in the cluster has an image of the virtual host, which greatly improves the security and stability of the virtual host, unless all the hosts in the cluster have problems, the cloud host will be inaccessible.

Simple example: VPS is the virtual presence of multiple virtual hosts on one physical host, and all of them will be scrapped if the host breaks.

Virtual machines create multiple virtual hosts on multiple physical hosts, and the failure of any one physical one will not affect the operation of the virtual machine.

VPS is a virtual host, and cloud server is equivalent to an upgraded version of VPS, of course, cloud server is more stable and reliable than VPS.

VPS is a virtual server, and multiple VPS can be divided into one server. The cloud server is based on the hardware of multiple server clusters through a certain technology division, so even if one of the servers is down, the cloud server will still operate normally, so the security should be better! Because the technical content is relatively high, ** is slightly more expensive!

The cloud server has an independent control panel, which can be deployed freely, which is more secure and stable.

If you are just a simple web page and **text introduction, then you can use the M1-S space, and you can upgrade to a larger space at any time in the future, and you can make up the difference when you upgrade.
