In a word, I personally think this is a B/S structure.

Cloud computing is a new form of service outsourcing.

Cloud computing platform is divided into public cloud and private cloud. Public cloud is the embodiment of the Internet in IT industry, which can provide users with relatively complete IT application outsourcing services. To some extent, the storage security problem is solved; Provide services completely in SaaS mode; Now that it is SOA-oriented, it will be convenient for users to expand their applications in the future. Therefore, a variety of services can be completed at one time through the public cloud, which undoubtedly reduces the IT outsourcing cost.

Lu, general manager of Wuxi Cloud Computing Center, believes that the cloud computing center is equivalent to buying hardware and software and packaging them to form online services. This is a service way beyond SaaS, infrastructure and platform, covering almost all aspects needed for enterprise informatization.

Public PK private cloud

For some large IT providers, they can provide both public and private cloud services. However, some users still think that private cloud is actually promoting new hardware products in disguise. Therefore, public cloud can better reflect the service characteristics of cloud computing.

Regarding the form of cloud computing, Wang Yang, vice president of IBM and general manager of IBM China Development Center, believes that IBM will continue to invest in public and private clouds. He said, "The resources provided by the private cloud can only be used within the enterprise. The public cloud is equivalent to a provider, providing resources for everyone to use. We will all move forward on private clouds and public clouds, with the focus on finding application value. For example, some large companies have testing needs in research and development, which requires a lot of human and financial resources to do. If there is a tested public cloud, this demand will be met immediately, so that cloud computing will be faster. "

Zhu, project director of IBM Greater China Cloud Computing Center, added that there is another kind of cloud between public cloud and private cloud, that is, the enterprise's private cloud computing platform does not provide services to all public customers, but only to its own business partners. There are many examples in America.

Government promotion is very important.

In February 2007, IBM helped Wuxi Taihu New City Science and Education Industrial Park to establish a cloud computing center to help enterprises in the park design, develop and test their own software products by using the allocated resources. Wuxi Cloud Computing Center is the first commercial cloud computing center in China, and the first person in China to eat cloud computing crabs. Therefore, the development of Wuxi Cloud Computing Center will affect the domestic business model of cloud computing.

For Lu, general manager of Wuxi Cloud Computing Center, the biggest difficulty in building Wuxi Cloud Computing Center is how to get government support. He said: "Our biggest problem is to let government decision makers know what cloud computing is and what it is used for. We compare cloud computing to a power plant. In the past, each unit had its own small power plant, but now it is powered by a central power plant. For example, every enterprise now has its own computing center, and the cloud computing center is a centralized IT service factory.

Another example is the concept of private cars and taxis. These two business models coexist, and taking a taxi is equivalent to online cloud computing services. If there is demand, just wave after the service. Both business models have their value. As for which business model will occupy a larger proportion in the future, it depends on the progress of technology and the acceptance of business models to others. "

The role of the government in promoting cloud computing cannot be ignored.

For example, Lu said that the charging standards, information security and industry standards of cloud computing all need government participation. For example, qualification issues, cloud computing services are like taxis. At the earliest, the government had strict regulations on the rental industry. So is cloud computing. Many users are worried about information security. The government can effectively eliminate users' concerns by formulating cloud computing standards and certifying cloud computing service providers.

Zhu revealed that at present, Wuxi Cloud Computing Center has a variety of application forms: first, development and testing; second, hosting services, mainly government e-government services, and e-commerce platforms. At the same time, we will cooperate with different ISVs to do some local application development on the cloud platform.

SaaS on the Cloud

Unlike the cloud computing center, another cloud computing giant, Google, has launched a service similar to SaaS. As early as 2007, Microsoft executives admitted that Google applications had posed a threat to them in the enterprise market. In February 2007, when Google launched the enterprise version of Google Apps, Forrester analyst Erica Drive regarded it as a direct competitor of Microsoft Office.

Google Apps costs $50 per user per year and can enjoy Google services such as email, instant messaging, calendar, web page creation, text and spreadsheets. These are all mainframes based on Google, and there is no need for hardware, downloading, installing and maintaining software.

In addition to the office suite, Google Apps has some other applications for enterprises to choose from.

Cordys, another cloud computing service provider, also formally joined the Google Enterprise Cooperation Program to provide structured business processes for the communication and collaboration tool components of Google Apps. Cordys Process Factory for Google Apps supports organizations of any size to use Google Apps in their core business processes and projects.

Li Dongxu, vice president of Cordys, said that with the help of cloud model, the combination of Cordys process factory and advanced version of Google Apps provides a solution for message passing and collaborative work, with lower cost and no need to install software. The combination of the two increases the configuration speed of business processes and situational applications, but the cost is lower than the price of a mobile phone.

The Cordys solution released this time enables Google Apps users to add structured processes to existing unstructured collaboration, thus transforming unstructured data in Google Docs spreadsheets into structured data sets and applications. This solution also provides conditions for building and using scenario application software in the cloud and integrating these software into enterprise applications and legacy software. Scenario applications include budget approval, project management, talent management and change control.

Cloud-based development

Cordys Process Factory for Google Apps is a development platform environment for building business processes in the cloud. Based on the "service platform" mode, this solution can help enterprises to quickly realize the situational application (MashApps) and meet specific business requirements at the fastest speed. Enterprises can migrate themselves to the cloud-based application environment by pay-as-you-go method, which will greatly reduce the overall IT cost, improve IT efficiency and accelerate innovation.

"Every vendor will decide its role in the whole cloud computing according to its own technical characteristics. Our positioning is that as a service level, we can quickly establish a cross-application, cross-database and cross-departmental process platform for customers throughout the cloud. " He ye, pre-sales director of Cordys North Asia, said.

Cordys is an architecture-based business operation platform, which allows users to quickly establish cross-system and cross-application processes, which may involve the internal network of the company or the cloud of the public network. Since 200 1, Cordys has built such a cross-system and cross-platform platform based on the Internet. On the one hand, it develops applications for R&D personnel, on the other hand, end users can use it through Internet browsers.

He ye said, "In the development process, our developers can use a web browser to develop without any client software. They can use a web browser to develop applications. Including the process, the user interface of the process itself, the business rules of the process, etc. Can be developed through a web browser. "

In addition, Cordys' business operation platform supports the concept of "multi-tenancy", "in the category of cloud computing or SaaS, because it may be used by countless users on the Internet."

The Cloud of Supercomputing Center

The landing of cloud computing has always been the focus of the industry. In fact, cloud computing has landed unconsciously. Shanghai Supercomputing Center was established in February 2000. It is the first high-performance computing service platform in China, which is open to the society, shares resources and has complete functions.

It also provides computing resources and application software suitable for various industries, which can provide users with computing energy, applications and power management in the form of services. To some extent, Shanghai Supercomputing Center is also a cloud computing platform. Due to the shortage of supply, there are already many enterprises waiting in line. In 2008, Shanghai Supercomputing Center started the third phase of construction, and plans to provide services for more enterprises.

Zhang, technical director of the platform in China, said, "Grid computing has three stages: the first stage is distributed cluster, and the second stage is enterprise grid or social-oriented network, which emphasizes the enjoyment of computing resources. Then the third stage is public grid or cloud computing. "

In addition, a very big demand in cloud computing is to build a dynamic data center. The technology of the platform can be used as a policy-based scheduling system to realize automatic control. For example, in the physical virtual server environment, the Platform can make statistical reports and charge fees, so the annual downtime of Shanghai Supercomputer does not exceed 1 hour.
