Where will the traditional servers go in the era of cloud computing?

The advent of the cloud is changing our perception of traditional it. The cloud is not as illusory as its concept, but it appears in various forms in front of us, and the most familiar one is cloud storage and cloud computing. The advent of cloud storage has changed the way some people store and habits, and what does cloud computing bring to us? Where does the server go in this cloud era?

What is cloud computing

Traditionally, the traditional server plays a vital role in the operation of the enterprise, especially the Internet company. Therefore, whether the establishment of its own computer room or a hosting server is also built on the basis of the entity server. Cloud computing, by distributing computing across a large number of distributed computers, rather than the local computer or remote server, makes the Enterprise data center run more like the Internet. This allows the enterprise to switch resources to the required applications and to access the computer and storage systems as needed. It's like from the old home soil heating mode to the central heating mode, means that the computational capacity can also be used as a commodity circulation, like gas, water and electricity, easy access, low cost. The biggest difference is that it is transmitted over the Internet.

Have to mention the virtualization

"Virtualization is the process of representing computer resources in a way that users and applications can easily benefit from, rather than expressing them in terms of their implementation, geographical location, or physical packaging." In other words, it provides a logical view, not a physical view, of data, computing power, storage resources, and other resources. "--jonathan Eunice, Illuminata Inc.

In the era of cloud computing, virtualization has become the most important and basic function of cloud services. Virtualization allows us to virtualize multiple servers on a high-performance server, running multiple identical or different operating systems and applications at the same time, with no impact to each other, with little difference in usage and traditional servers, so that while implementing the same applications and functions, A significant reduction in the number of entity servers.

Configure a strong cloud server

What is a cloud server

Cloud computing is the business data to be processed by the enterprise through the cloud server rather than the entity server. Cloud servers can be competent for intensive virtualization and applications that can extend the application database. So what are the features for a cloud server?

1, with operational performance of the Super multi-core processor

The server in our impression of performance is very strong, of course, one of the root of the powerful is its strong operational performance of the processor. Not only does it run at a high frequency, but also has more kernel numbers, such as Dell's PowerEdge R820 server, with 4 frequencies up to 2.6GHz of 6 core Xeon E5-2600 processor, the total number of CPUs has reached 24! This provides powerful operational support for virtualization, It's easy to deal with cloud computing.

2, super Large capacity memory

For a cloud server, the more cores the processor has, the more powerful servers can be virtualized on virtual machines. Therefore, a large amount of memory support is required to ensure that all virtual servers can run quickly. In a cloud server, you can often install up to hundreds of gigabytes or even terabytes of memory, which provides powerful memory support for cloud computing. You can imagine that the cloud-only server is virtual, but performance is still stronger than some low-end entity servers. And the cost of cloud computing is the absolute advantage relative to the entity server.

3, Super High-capacity storage

We can use a classic word to describe cloud server: You are not alone in the fight! True, a server can run several virtual applications in a powerful processor and super high-capacity memory, and the hard disk remains the most important storage device for the server. In order to ensure that each virtual server in the cloud computer has enough storage space, the cloud server has a feature, that is, a lot of hard disk bits, and in order to increase the number of hard drives, It also uses a smaller size 2.5-inch hard drive, so that the entire cloud server has terabytes of high-capacity storage and provides storage capacity for the application of the virtual server.

Cloud computing, where the server goes

With the increasing volume of business, the traditional server performance is stretched, coupled with the long-term uninterrupted operation of the server, equipment aging is also more prominent. So what about the development of the business? The traditional way is generally to buy or add new servers to cope with the growing volume of business, and the purchase of new servers, the increase in the number of hosting rooms, the cost of access to the Internet is also rising. And cloud computing can reassure users. Thanks to the development of cloud servers, companies will no longer have to spend huge sums of money to buy new servers and hosting rooms, and the annual rents of cloud computers are also very cheap, so companies can benefit directly from it, and of course companies may buy high-performance cloud servers to upgrade and extend entity servers, In order to achieve small investment in large profits.

With the help of network and powerful cloud server, the number of entity servers is reduced, not only the cost of purchasing new server and server hosting and Multi line Internet access is saved for enterprise. It also reduces the cost of cooling measures in the engine room and the electricity bill, thus achieving energy saving and emission reduction. But cloud computing also does not seem to be perfect, because a large number of virtual servers exist, so cloud server disaster recovery is particularly important, and for operations and maintenance personnel also put forward a higher technical requirements. As a result, cloud servers will focus on large data centers in the cloud computing era, while enterprise internal applications tend to be more skewed towards lower-priced tower servers or micro-servers.
