Cloud computing System Panorama

Cloud computing: Technology, applications, standards and business models Mr. Zhou Hongpo, author of the book from his rich practical experience, with a scientific attitude, to cloud computing technology evolution, application and business model did a clear and strong analysis, in order to brush off the fog of cloud computing, to restore the true face of cloud computing, Provide an empirical insight into the reader. This section presents a panoramic view of cloud computing systems. &http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp;

As for the SaaS model and technology in the NIST Cloud computing SPI System, the 7th chapter of this book has been systematically introduced, no longer to repeat. For the division of the SPI, the current mainstream of the industry generally agree that many companies, governments and advisory body reports are gradually described in the SPI approach to cloud computing. For example, Gartner has done the comparison shown in Figure 9-56 for mainstream cloud computing companies in accordance with the SPI Division.

Figure 9-56

However, some in the industry do not fully agree with the SPI division, there are a number of divisions to take a more detailed approach, including cloud computing system monitoring and management, development tools, to separate the cloud storage from the IaaS, and so on, as shown in table 9-1.

Concepts such as virtualization, SaaS, and cloud computing can be said to be an attack on the Microsoft "suite software" Empire as described above, but Microsoft has strong strength and foundation and will not be "passively beaten". Microsoft itself as the existing software model of the biggest "vested interests", these ideas itself is not proposed, Microsoft to do cloud computing is completely forced out, if others put forward, Microsoft will also introduce corresponding "recruit". Just like when Netscape was launched, Microsoft used Internet Explorer and its monopoly on desktop systems to dissolve, and to "eat" the Netscape alive. But this time Microsoft may be "doomed", although Microsoft can launch good virtualization (Hyper-V), PaaS (Azure, as shown in Figure 9-57) and SaaS (Windows Live) products and services, but still appear "to cope with, four embattled." With the leading edge, Microsoft is still likely to lead and succeed in the cloud-computing bandwagon (it is still one of the cloud's "Big 5": IBM, Microsoft, Amazon, Salesforce and Google "75"), But it is unlikely to beat the competition as thoroughly as it did when he ate Netscape.
