Looking at cloud computing from industry chain

Only a clear understanding of the cloud industry chain, to ensure that the cloud itself is not biased understanding. People always think that cloud computing is concentrated, is the opposite of distribution, in recent years, people have recognized the role of centralized computing, but as the cloud computing industry chain of the mature, people gradually found that strong demand continues to consume new computing resources, in any case to improve the CPU, memory, Hardware configurations such as hard disks do not seem to meet the continued growth of computing needs, so people are betting more on grid computing, which increases computing resource utilization, and can connect more islands-like computing power, so cloud computing usually has a distributed infrastructure,　　And the distributed system can be real-time monitoring to achieve the purpose of efficient use, cloud computing industry chain are all part of the existence. Equipment supplier equipment supplier of the long-standing, but the cloud computing equipment suppliers and the common IT equipment vendors are different, cloud computing is not very new technology, so the characteristics of cloud computing devices in addition to some hard indicators, more important is the idea of cloud.　　Cloud computing equipment vendors can be divided into server suppliers, storage equipment suppliers and network equipment suppliers three kinds. Servers: IBM, Dell, Tidal, HP storage devices: Dell, NETAPP network devices: Cisco, Huawei, Juniper infrastructure, or service consumers can get services from a sophisticated computer infrastructure via the Internet, which is called the infrastructure, the service (IaaS), and provides　　Consumer service is the use of all facilities, including processing, storage, network and other basic computing resources, users can deploy and run arbitrary software, including operating systems and applications.　　Computing services: Amazon, Rackspacer, Gogrid, Joyent, Flexiscale, Cloud Express technology storage services: Amazon, Rackspace, Google, Microsoft Monitoring services: Cloudkick software and solutions provider Cloud computing software solution provider can be said to be one of the most fierce battlefield, domestic and foreign manufacturers are also from the ordinary solution provider to the cloud computing Solution Provider transformation. Cloud computing software and solution providers have emerged to better help users plan their cloud computing implementations.　　In large categories, software and solution providers typically offer two services, including business solutions and open source solutions. Business Solutions: VMware, Microsoft, Citrix, IBM, HP Open Source solutions: AMD, Dell, Cisco, Intel platform services to consumers is to deploy customers with the development language and tools provided to the vendor's cloud computing infrastructure. Users do not need to manage or control the underlying cloud infrastructure, including networks, servers, operating systems, storage, etc., customers can control which applications are deployed, or they may control the configuration of the managed environment where the application is running.　　Application operating platform: Microsoft, Google, Salesforce.com, Sina, SAP Application management platform: Engine Yard trackvia.com Application Development test Deployment platform: Soasta, Utest, Cloudswitch Software as a service The service provided to the user is an application that operators run on the cloud computing infrastructure, and users can access the thin client interface on a variety of devices, such as browsers.　　Users do not need to manage or control any cloud infrastructure, including networks, servers, operating systems, storage, and so on. Salseforce.com, NetSuite, Google, Microsoft, 800 customers, Zoho the industry chain of cloud computing, the most popular mind must be IaaS, PAAs and SaaS of the three words, but in fact this is only the basis of cloud computing three service models, The industry chain of cloud computing is more than that.
