Cloud Hosts"Cloud Hosting can be seen as a new generation of shared hosting. First of all, the host company makes its hardware and network lines into one"Cloud"and then offer some leads to this one"Cloud"The network interface API is available to customers. At this point, each customer is no longer sharing a specific server, but all servers in the cloud.

For example: Yimai Cloud).

The advantages of cloud servers are based on cloud computing technology, and compared with independent servers, they have the following characteristics:

1. From the technical aspect: cloud computing technology is used in cloud computing technology, and cloud computing technology integrates various software and hardware technologies such as computing, network, and storage. Dedicated servers, that is, independent, do not integrate these resources.

2. From the security aspect: the cloud server has natural anti-ARP attacks and MAC spoofing, snapshot backup, and data will not be lost permanently. Dedicated servers, on the other hand, don't have this feature;

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

4. In terms of flexibility: users can increase their own configuration in real time, and there is a large space for expansion; Dedicated servers, on the other hand, have limitations in this regard, and if you have a new application, you have to buy another one.

5. From the perspective of performance: the cloud server is 4 times the computing power of the same configuration of independent servers, which can meet the requirements of high-performance computing;

6. From the perspective of stability, cloud servers can be automatically migrated due to failures, which means that if a cloud server fails, the applications on it will be automatically migrated to other cloud servers. Dedicated servers don't have this function, and if they do, they will go down.

7. From the perspective of energy saving, the automatic migration technology of cloud servers based on cloud computing means that at night, the utilization rate of physical servers is not high, and the automatic migration technology will concentrate the application on several physical servers, and other physical servers can be dormant, so as to save energy.

Cloud hosting is a new generation of host rental service, which integrates high-performance servers and high-quality network bandwidth, effectively solves the shortcomings of traditional host rental, such as high and uneven service products, and can fully meet the needs of small and medium-sized enterprises and individual webmaster users for low-cost, high-reliability and easy-to-manage host rental services.

Hello landlord, if it is an enterprise that chooses a server, it depends on what aspect of the business it is doing. If it is an enterprise, the general requirements for host configuration are not high, even a few hundred trillion virtual hosts can be satisfied, if the overall security requirements are higher, you can also choose cloud hosts, or independent servers. If you want to place other types of services in the enterprise, you can select a suitable host based on the requirements of the business for machine hardware and bandwidth.

Virtual machines (cloud servers).

Concept: A cloud server is a simple, efficient, secure, reliable, and elastically scalable computing service, which allows users to quickly create or release any number of cloud servers without purchasing them in advance. This kind of server, do not need to spend money to buy host, hard disk, CPU, memory and other hardware back to assemble by yourself, it can be quickly created on the web page, can also be very convenient in the later stage to increase the number of CPUs, improve memory, increase hard disk capacity, improve network bandwidth, etc., all this, do not need you to power off like a physical machine, disassemble the chassis to increase, only need to suspend the operation of the server, and then click the mouse on the background management of the web page can be completed, Don't worry about the compatibility of the new hardware, because everything is virtual.

The concept of cloud hosting:

Cloud hosting is a new generation of host rental service, which integrates high-performance servers and high-quality network bandwidth, effectively solves the shortcomings of traditional host rental, such as high and uneven service products, and can fully meet the needs of small and medium-sized enterprises and individual webmaster users for low-cost, high-reliability and easy-to-manage host rental services.

The position of cloud hosting in the Internet.

Cloud host 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 are derived from cloud computing platforms. The cloud computing platform integrates the three core elements of Internet applications: computing, storage, and network, and provides users with public Internet infrastructure services.

The difference between cloud hosting and traditional VPS hosting:

Although cloud virtual machine is a virtualization technology similar to VPS hosting, it is different from VPS technology. VPS is the use of virtual software, VZ or VM on a host to virtualize a number of independent host-like parts, 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.

Server clusters, along with virtual machine software, are invisible and agnostic to the user. It gives you the feeling that a computer host provides services to you, but in fact, at the remote end, it may be a server that divides some resources to you, or several servers may be virtualized into a host for you.

A service that charges for a fee on an on-demand basis.

Cloud servicesCloud services refer to the on-demand and easily scalable access to required services over the network. This kind of service can be related to IT and software, the Internet, or other services, which means that computing power can also be circulated through the Internet as a commodity.

The main thing about cloud hosting is stable performance, reliable hardware, no need to worry about maintaining hardware, and the hardware configuration of the host can also be freely upgraded or replaced.

Cloud hosts are based on cloud technology in recent years, based on the launch of host products, unlike virtual hosts located in a single physical server, cloud hosts themselves are based on cluster servers, not limited by physical servers, can flexibly call the entire cluster server on the bandwidth, memory and hard disk and other resources, to maximize the use of resources. Therefore, the cloud host is more flexible in terms of configuration upgrade, attack defense, etc., and the operation is more stable, and it can be migrated in real time in the event of a failure, and the data is backed up multiple times at the same time, and the security is more guaranteed. Cloud hosting has basically the same permissions as the server, and is lower than the rental of independent servers, which can save a lot of hosting costs, and has more advantages in performance, which is the mainstream choice for building a website.

Cloud services are Internet-based modes of augmentation, use, and interaction of related services, typically involving the provision of dynamically scalable and often virtualized resources over the Internet. Cloud is a metaphor for the network, the Internet. In the past, clouds were often used to represent telecommunication networks in diagrams, and later they were also used to represent the abstraction of the Internet and the underlying infrastructure.

Cloud services refer to the services you need over the network in an on-demand, easily scalable manner. Such services can be IT and software, Internet-related, or other services. It means that computing power can also be circulated as a commodity through the Internet.

A true cloud host needs to have the following three characteristics:

In other words, if the user's data is lost or deleted by mistake, it only needs to be restored with one click, just like the image recovery of the PC, and there is no need to back up the data through the administrator of the hosting provider like the traditional IDC host in the past, and then re-import it back to the server after recovery, which are two completely different concepts and technologies.

2. Look at the host resources. True host resources are exclusive hardware and bandwidth resources that are never shared with others. VPS hosts, on the other hand, will have resource contention, because these are multiple hosts virtualized on the same server, and the resources on one server have an upper limit, so it is naturally impossible to have "inexhaustible" computing resources for small and medium-sized enterprise users like a resource pool composed of thousands of server clusters.

3. Look at the underlying architecture. Real cloud hosts are based on massive server clusters, and architectures such as Hyper-V and VMware are only based on a single physical machine and cannot support clustered clouds. For example, if it is a copycat cloud host, there is a high probability of a single point of failure, which does not exist in a real cloud host.

Similarly, when users need to upgrade their virtual machines, real virtual machines support smooth upgrades, while copycat virtual machines need to export the data on the server for backup before they can upgrade.

Cloud hosting is a new generation of host rental service, which integrates high-performance servers and high-quality network bandwidth, effectively solves the shortcomings of traditional host rental, such as high and uneven service quality, and can fully meet the needs of small and medium-sized enterprises and individual webmaster users for low-cost, high-reliability and easy-to-manage hosting rental services.

At the same time, it is also an important part of cloud computing in infrastructure applications, integrating computing, storage and network resources IT infrastructure capacity leasing services, and can provide on-demand use and pay-as-you-go server rental services based on cloud computing models. Customers can deploy the required server environment through a self-service platform with a web interface.

Something like this can be controlled from a remote desktop computer.

Internet access is available. Can be made a web page. It can be hung up 24 hours a day.

The real cloud host is the cloud host, a virtualized virtual machine. It's not a physical machine!

Cloud hosts are actually an upgraded version of VPS. It is the use of a technique to virtualize multiple independent host-like portions on a set of clustered servers. Each host in the cluster has an image of the virtual machine.

As a result, the performance and security of cloud hosting are greatly improved. When there is a problem with one of the hosts in the cluster. It does not affect the normal use of the virtual machine.

Only the failure of all hosts will affect the virtual machine. It functions and serves exactly the same purpose as a server. Most of them are used to put **.

Of course, there are other applications as well.

A cloud server is a simple, efficient, secure, reliable, and scalable computing service. It's simpler and more efficient to manage than a physical server. Users can quickly create or release as many ECSs as they want without purchasing hardware in advance.

Reduce DevOps effort and overall IT costs, allowing you to focus more on core business innovation.

Cloud hosts are an important part of cloud computers in infrastructure applications. It is located at the bottom of the cloud computing industry training pyramid. The product is derived from the cloud computing platform. Cloud hosting is a virtualization technology similar to VPS hosting.
