Computing power of group cloud server
how to ensure the safe, continuous and stable operation of enterprise data in information system is the most important problem faced by information management department
with the development of network, cloud procts are more and more popular with webmasters. What are the characteristics of cloud server
first, the operation and upgrade of cloud server is more convenient
traditional server resources are limited. If you want to get better skills, you can only upgrade the cloud server. The so-called "cloud" refers to the network and the Internet. Cloud server is a simple, efficient, safe and reliable processing capability. Scalable computing services. The operation is more convenient. If the original configuration is too low, you can upgrade the CPU, hard disk, memory, etc., without having to re install the system, and without affecting the previous use< Second, faster access to the cloud server
the cloud server is also known as the cloud host. The bandwidth used is usually multi line interworking. The network can automatically detect which type of network is faster, and automatically switch to the corresponding network for data transmission< Third, cloud server storage is more convenient
data can be backed up on the cloud server, so even if there are hardware problems, the data will not be lost. In addition, the use of cloud server only needs the normal maintenance of service providers in the later period, which solves a lot of worries for enterprises< Fourth, the security and stability of cloud server
cloud server is a kind of cluster server, which can virtualize many parts similar to independent server, and has high security and stability. In addition, the cloud server also supports the rapid reconstruction of different nodes. Even if the computing node is interrupted or damaged, the virtual machine can be reconstructed by other different nodes in a very short time without affecting the integrity of the data< 5. Cloud server has higher cost performance
cloud server pays on demand. Compared with traditional servers, cloud servers are more cost-effective and will not waste resources
of course, in addition to these remarkable features, it is more important to choose a well-known cloudeasy platform service provider to make the cloud server more simple and efficient and not cause unnecessary losses to the enterprise.

as we all know, the service types of cloud computing can be divided into three levels: IAAs, PAAS and SaaS. These three levels constitute the overall architecture of cloud computing technology, which may include some virtualization technologies and applications, automatic deployment, distributed computing and other technologies. The advantage of this technical architecture is that it can show excellent parallel computing capability and large-scale scalability and flexibility< br />
the cloud service that we usually refer to is an on-demand and measurable IT service mode supported by the above technical architecture of cloud computing. This service mode can replace the local IT service
Why are concepts confused
this point actually goes back to the enterprise level cloud computing vendors. Some early cloud computing vendors are suspected of advocating and hyping the concept of cloud computing. Up to now, the trillion scale market opportunities provided by cloud computing have been obvious to all, and the national government has been supporting the innovation and popularization of cloud computing technology, In this way, for some users who do not have a high degree of technical mastery, it is easy to confuse some details of cloud computing and cloud services< br />
at the same time, for many early users who paid for cloud computing services, their early demand for cloud computing was limited to it infrastructure. The most typical one is Amazon's EC2, which provides Web services so that users can flexibly run programs on virtual hosts. However, EC2 should be translated as elastic computing cloud. The term "cloud computing" is directly used in China, and later it is used to summarize various cloud computing services<
small and medium-sized enterprises become market boosters
will cloud services have greater value than cloud computing
once there was such a voice in the instry, that is, cloud services will graally abandon cloud computing and other technical architectures in the future development, which will have greater value than the traditional cloud computing architecture. The author really does not agree with such a view. From the perspective of users, in addition to analyzing the service architecture and service mode of cloud computing, we also need to test and screen the overall cloud platform, bug analysis, data analysis tools, promotion platform and other services. For example, we usually describe cloud computing as the water, electricity and coal of the Internet, that is, the basic resources, but most users do not care about how these basic resources come from, but care about what can be used to do. From this point of view, cloud services are more popular than cloud computing, which means a larger market
so in a word, cloud services actually run on cloud computing. As the technical infrastructure of the whole cloud platform, cloud computing plays a very important role in promoting the rapid development of the whole cloud computing business. Giants can make up for the lack of infrastructure through self-research, Entrepreneurs can also rent public cloud or private cloud to break into cloud computing
the more important progress in cloud computing is to provide storage and network virtualization, so that the cloud server is really equivalent to a physical server with moderate performance, so as to realize the on-demand allocation of resources, high utilization and high availability. It provides a very loose structure from the bottom, so that a variety of tasks can be freely combined and do not interfere with each other; It is contrary to the highly organized structure of parallel computing.

After understanding cloud computing, let's go back to cloud computing server. Now there is no clear definition or unified standard for cloud computing server. Compared with traditional server, traditional server includes processor mole, storage mole, network mole, power supply, fan and other devices. Cloud server focuses on high-performance throughput computing capacity, and the total workload over a period of time. Therefore, the architecture of cloud server is very different from that of traditional server. In architecture, cloud server architecture includes cloud processor mole, network processing mole, storage processing mole and system processing mole. The advantage of this architecture makes the cloud server can greatly improve the utilization, using multiple cloud processors to complete the system design, introcing the concept of low-power management to complete the centralized rendancy management of the system, and saving a lot of repeated hardware in the system. Cloud server generally includes thread, core, processor, network, accelerator and other functional units. Therefore, cloud computing generally has a huge amount of data input or massive working set. So what capabilities should the server have? Let's talk about it in detail
high density
high density and low cost are basically the basic requirements of cloud server. According to the characteristics of cloud computing center, cloud server should be consistent with the characteristics of high density, low power consumption and low cost of cloud computing center, that is, it is mainly for large-scale deployment of cloud applications. High density servers can rece latency and improve response speed. At present, high-density servers are mainly divided into multi rack and blade servers. Virtualization Server Virtualization ability, can be said to directly affect the effect of cloud computing. The server virtualization technology realizes the real-time migration of some virtual machines from high load nodes to low load nodes, merges multiple low load virtual machines into one physical node, and closes the rendant idle physical nodes, so as to improve the utilization efficiency of resources, balance the load, and guarantee the performance of upper layer applications, At the same time, it also achieves the purpose of recing energy consumption. Therefore, cloud computing can realize the deployment and configuration of virtual machines by using server virtualization technology. Through the rapid deployment and real-time migration of virtual machines, the efficiency of the system can be greatly improved, and the scalability of the software system can be realized by adjusting the resources of virtual machines, so as to ensure that the system can quickly recover from the failure and continue to provide services, The reliability and stability of the system are improved. Therefore, when purchasing a cloud server, the support of server hardware virtualization is an important factor to consider the server. Scale out according to the first feature of cloud computing, "super large scale", the scale out capability of cloud computing server becomes crucial. At present, Intel has launched a scale out storage solution. Combined with Intel's hardware, it can provide higher database and better scalability for such a large number of file access, The Intel 10 Gigabit network card can be combined with Intel virtualization technology to provide a more efficient, safer and simpler way for the whole cloud computing center, ensuring the flexibility of cloud data center. In some form, parallel computing cloud computing is the technical route of distributed computing, parallel computing, grid computing and so on. Conceptually, cloud computing can be regarded as the organic combination of "Storage Cloud" and "computing cloud", and computing cloud refers to parallel computing. Therefore, the infrastructure of cloud computing is to ensure the realization of parallel computing
What are the characteristics of cloud computing 1. Super large scale "cloud" has a considerable scale. Google cloud computing has more than 1 million servers, and Amazon, IBM, Microsoft and Yahoo have hundreds of thousands of servers“ "Cloud" can give users unprecedented computing power 2. Virtual cloud computing supports users to obtain services by using various terminals at any location. The requested resources come from the "cloud" rather than a fixed tangible entity. The application runs somewhere in the "cloud", but in fact, users do not need to know the specific location of the application. They only need a notebook or a PDA to obtain various super powerful services through network services 3. High reliability "cloud" uses data multi fault tolerance, computing node isomorphism interchangeability and other measures to ensure the high reliability of services. Using cloud computing is more reliable than using local computers 4. General cloud computing is not specific to specific applications. It can be constructed as a variety of applications under the support of "cloud", and the same "cloud" can support different applications at the same time 5. The scale of highly scalable "cloud" can be dynamically scaled to meet the needs of application and user scale growth 6. On demand service "cloud" is a huge resource pool, which users buy on demand and charge like tap water, electricity and gas
requirements of cloud computing for servers

summary:
to sum up, cloud computing does not have very high performance requirements for the server itself, but it has certain requirements for the structural flexibility of the server. On the other hand, it should pay attention to the calculation density, virtualization ability and the ability to realize parallel computing of the server, So when we choose the server again, we should combine the above four requirements to achieve twice the result with half the effort
