In the era of cloud computing This is the real cloud!

In the era of cloud computing, many people are talking about cloud computing, and what exactly is the real cloud? Please see below. Cloud computing is an internet-based computing method in which shared hardware and software resources and information can be supplied to computers and other devices on demand. Typical cloud-computing providers often provide a common network business application that can be accessed through software such as browsers or other Web services, while software and data are stored on the server.

Cloud computing services typically provide common, online business applications that are accessed via browsers, and software and data can be stored in data centers. Cloud computing has several important characteristics.

Support for heterogeneous base resources

Cloud computing can be built on different infrastructure platforms that can be effectively compatible with different kinds of hardware and software infrastructure. Hardware basic resources, mainly including the network environment of the three types of equipment, namely: computing (server), storage (storage equipment) and network (switches, routers and other equipment), software infrastructure resources, including stand-alone operating system, middleware, database and so on.

Support dynamic expansion of resources

Support the dynamic expansion of resources, realize the network redundancy of the basic resources, means to add, delete, modify the cloud computing environment of any resource node, or any resource node abnormal downtime, will not cause all kinds of business interruption in the cloud environment, also will not cause the loss of user data. The resource nodes here can be compute nodes, storage nodes, and network nodes. The dynamic flow of resources means that the resource scheduling mechanism is realized under the cloud computing platform, and the resources can be transferred to the needed place. In the case of the overall increase of the system business, idle resources can be started and included in the system to improve the load capacity of the whole cloud platform. In the case of low load of the whole system, the business can be concentrated, and other idle resources into energy-saving mode, so as to improve the utilization of some resources, the other resources green, Low-carbon application effect.

Support heterogeneous multi-service system

On a cloud computing platform, you can run multiple different types of business at the same time. heterogeneous, which means that the business is not the same, not already or defined beforehand, but should be the user can create and define services. This is also an important difference between cloud computing and grid computing.

Support mass Information processing

Cloud computing, at the bottom, need to face a variety of basic hardware and software resources, at the top, need to be able to support a variety of heterogeneous business at the same time, and specific to a business, often also need to face a large number of users. Therefore, cloud computing must face massive information interaction, and it needs efficient and stable mass data communication/storage system to support.

On demand, billing by volume

On demand, is the external feature of the cloud computing platform supporting the dynamic flow of resources. Cloud computing platform through virtual spin-off technology, computing resources can be isomorphic and measurable, can provide small to a computer, more than thousands of computers computing power. Based on the utility calculation, according to the volume billing, after the cloud computing platform is implemented on demand, the chargeback is also the effective charging form for the cloud computing platform to provide services when it comes out.
