What does cloud hosting mean? Ask for advice

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.

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.

It's that the host is not with you, similar to a cloud server.

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.

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.

1. Cloud web hosting.

2. Cloud server, also known as cloud computing server or cloud host, is a host product in the cloud computing service system, its management method is simpler and more efficient than physical server, which can help users quickly build more stable and secure applications, reduce the difficulty of development and operation and maintenance and overall IT costs, and enable users to focus more on core business innovation. AdvantagesUsers who use cloud servers can freely install the operating system on it, with very high efficiency and free control permissions. The cloud server is moderate, flexible to use, high security performance, does not limit the database, has no size limit, and all hardware resources and network resources are completely exclusive to the user, and have complete control.

Deficiencies cloud server is a cluster, their functions need to assist each other to complete, without any property rights, performance and stability are worse than traditional servers, easy to be affected by i 0, more suitable for network stability and host performance requirements for small enterprises and mobile game industry.

Cloud host is a virtualization technology similar to VPS server, cloud host is a new type of host, which can be regarded as a micro server. (For example, Yimai Cloud launched a permanent activity of enterprises to purchase cloud servers for 0 yuan) is to virtualize a number of parts similar to independent servers on a group of cluster servers, and there is a mirror image of the cloud server on each server in the cluster, which greatly improves the security and stability of the virtual server, and there is no instability in the ** space on the cloud host.

1.Introduction to Virtual Machines:

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 platform integrates the three core elements of Internet applications: computing, storage, and network, and provides users with public Internet infrastructure services.

2.Cloud Host Features:

Cloud host is a kind of 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. Cloud hosting is a next-generation hosting rental service that combines high-performance servers with high-quality network bandwidth.

Cloud HostsCloud Hosts, Cloud Servers Abbreviation.

Elastic server (ECS): A group of cluster hosts is used to create multiple similar independent hosts, and each host can operate independently. It 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, 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.
