Revan: Why cloud computing is hard to understand

But why use cloud computing? It originates from the easy to develop use of consumer it (Web2.0) work and differs from the already existing difficult to use http://www.aliyun.com/zixun/aggregation/13597.html "> Enterprise IT System." A Web2.0 page allows its users to change content in interactions with other users, and web1.0 users are restricted from interacting with Web1.0, only passively browsing information. Although the Web2.0 terminology suggests a new way to the World Wide Web, it does not involve new technologies, but it has accumulated many changes in software developers and end users. "I think web2.0 is a jargon and no one knows what it means," Timbernerslee, the World Wide Web inventor, clarified. If Web2.0 is a blog and wiki for you, it's a communication between people. The web is designed to be a space for people to interact. In short, Web2.0 is not a new technology, it is a usage pattern that appears. Corresponding to cloud computing, it is a usage pattern that leverages existing IT resources.

Again, cloud computing is not a new technology; it's a new delivery model.

The key point is that cloud computing focuses on the end user, for a person or community to be able to do what he wants, without the need for special IT support. and its technical layer is abstract, hidden, and simply by painting "A cloud" to express. The same approach has often been used to describe the internet itself in a number of previous technical drawings.

WEB2.0 Technology is designed to accomplish human-centric collaboration, interaction, and search, and for traditional it technology, Web2.0 is used to improve the availability and flexibility of existing IT resources. This is the use of virtualization to share computing resources to reduce costs and system management issues. Web2.0 environments are the primary support for computing resource flexibility, which is based on limited users in known limited applications. Web2.0 based on the number of users and services to deploy, is a complete dynamic on-demand mode.
The trend in existing enterprise it to improve cost and flexibility is achieved by means of virtualization, which is also known as part of cloud computing, and the enterprise is gradually migrating from its providers to web-based applications. Therefore, as an internal cost-saving, the basic usage pattern of external customer collaboration or use scenario to define cloud computing is more helpful than the technical definition.

The concept of cloud computing is emphasized differently in different regions of the world. The North American market, for example, is more focused on new IT systems, while European markets focus on new market positioning and service delivery patterns, while Asian markets focus on the ability of remote service centres on demand.

The real shift in business demand is driven by the popularity of definitions of usage. As an automated business process and improve the efficiency of the enterprise background it has done a good job, a lot of research shows that system stability, optimization, etc. are doing very well.

But now the integration of business with customers, suppliers and trading partners is an important task. Traditional it has done very little in this respect, and it is not appropriate to be engaged in the main technologies and methods of tight coupling as well as the application of data set as user driven enterprise foreground application. The technologies needed can be summed up in terms of "delivering a push" to "demand-driven" data, information, and services.

The increased business needs are focused on front desk activities that focus on improving corporate innovation, boundaries, market share, and customer service.

In order to realize the real business innovation value of the enterprise, it is necessary to deliver different services around the edge of the enterprise to deal with these changes. The ability to use user-centric Web2.0 technology is part of this meaningful answer. This flexible-mode technology combined with services supports this shift in emphasis on commercial technology (BT) in the foreground, rather than a single application, combined with user-driven collaborative services.

It's not just a technical and commercial match; it's a supply side match. The new Web2.0 requirements are delivered quickly and even in real time through the cloud, with absolutely no capital investment or timing, as compared to the traditional it annual budget cost coverage pattern. In fact, many cloud-based foreground services may be weeks or months of service life cycle as a continuous change in business requirements to adapt to the growth of global dynamic characteristics. Therefore, providing pay-as-you-go resources On demand is a key driver of cloud computing. This direct cost distribution to the business user's capital investment model is distinctly different from the traditional early-stage investment full coverage of the traditional it model.

While cloud computing lowers costs, it correspondingly reduces the complexity of providing computing resources, which can also be used for shared service centers that operate more efficiently. Focus on the people, experience, and synergy of any combination from the needs of the business front.
There are many ways to make the cloud change the business and the economy, most of which are unpredictable, but they have surfaced. Business is changing more like technology itself: more adaptable, more intertwined and more personalized. These developments may not be new, but they will accelerate their development with the help of cloud computing.
