What Is Cloud Computing Architecture?

Cloud computing, at least as an extension of virtualization, has grown in scope. However, cloud computing cannot yet support complex enterprise environments. Therefore, cloud computing architecture is on the horizon. Experience shows that before cloud computing matures, we should pay more attention to the details of system cloud computing architecture. Based on the analysis of some existing cloud computing products and some personal experience, a set of cloud computing architecture is summarized. The cloud computing architecture can be divided into four layers.

Cloud computing is another revolutionary change in information technology following the big shift from the mainframe computer to the client / server (C / S) model in the 1980s. On August 9, 2006, Google CEO Eric Schmidt first proposed the concept of cloud computing at the Search Engine Conference (SES San Jose 2006). Cloud computing is the product of the integration of traditional computer and network technologies such as grid computing, distributed computing, parallel computing, utility technology, network storage, virtualization, and load balancing. Its purpose is to organize and integrate shared software / hardware resources and information through network-based computing, and provide it to computers and other systems for use as needed ^[1]

Generally speaking, the generally accepted cloud architecture is divided into three layers: infrastructure layer, platform layer and software service layer. The corresponding names are IaaS, PaaS, and SaaS. IaaS, Infrastructure as a Service. The Chinese name is Infrastructure as a Service. As shown in Figure 1.

In recent years, cloud computing has become a key area of focus for major developed countries. It is in the tide of cloud computing development, and China's cloud computing strategy is also steadily advancing. Facing the rise of the latest technology represented by cloud computing, 51CTO, as China's leading IT technology community, stands at the forefront of technological development. It has held the Cloud Computing Architect Summit on October 25, 2012, uniting many IT technology leaders Enterprises jointly build a platform for architects to communicate and communicate with each other to share practical experience in the development and application of cloud computing, big data and other related IT technologies, and to exchange the latest technology trends and research results at home and abroad.

The 2012 Cloud Computing Architects Summit brought together the world's top IT companies as front-line architects, focusing on the technical applications of public and private clouds, storage and data architecture in the cloud era, big data mining analysis, cross-platform solution demand implementation and performance tuning. Wait for many hot technical topics, and gather with more than 1,000 front-line technicians across the country to talk about IT ^[3] .
