Five years, what is cloud computing?

The term cloud computing has been proposed for more than five years. Is it time to ask whether the problem is outdated? It's not out of date! From the concept of cloud computing formally to today, more than five years, more and more enterprises into the cloud computing industry, to promote the development of cloud technology market. However, cloud computing is not gradually clear because of its development, but because companies from their own point of view to explain cloud computing and make this concept increasingly vague.

Lack of an accurate popularization definition

In fact, cloud computing has always had a well-defined definition. The National Institute of Standards and Technology (NIST) defines cloud computing as the industry's recognized authoritative version: Cloud computing is a model that enables you to get the resources (for example, networks, servers, storage, applications, and services) from a pool of configurable computing resources, anytime, anywhere, easily, and on demand. Resources can be quickly supplied and released, minimizing the workload of managing resources and interacting with service providers. The basic features of cloud computing are: on-demand self-service, ubiquitous network access, resource sharing pool, fast and flexible, and metered payment services.

This version tends to be professional, full of technical vocabulary, it is difficult to let the unprofessional (most of the end users of cloud computing happens to be such people) understand the nature of cloud computing. So, the "cloud is what" of the popularization of the interpretation of the oven.

"What do we discuss about cloud computing?" In a way, I think the best way to understand cloud computing is to work in a working environment where our technology industry and all IT staff will serve the company. This is the way to best serve the current PC, phone, TV, Internet, and enterprise database business. This is an opportunity. Microsoft CEO Ballmer (Steve Ballmer).

"The earliest people just put the money under the pillow, then have a bank, very safe, but to cash up more trouble." So with further development, it is now up to banks to take money from any one of the outlets, even through ATMs or foreign channels. In an analogy: just like electricity does not require every household to equip a generator to buy directly from a power company. "Cloud" brings is such a change-by the Google, IBM, such as professional network companies to build computer storage, computing centers, users through a network of browsers can be very convenient access to the "cloud" as data storage and application services center. --Lee Kai-fu, former Google China president.

There are more and more enterprises in the original product services in front of the "cloud" word, from "cloud computing" expanded more nouns-cloud mail, Cloud mobile phone, cloud storage ... The popularity of these nouns has gradually equated web application services with cloud computing. As long as the network to provide users with services, is doing cloud computing. As a then, even some Web 2.0 apps are touting "we're also doing cloud computing." Cloud computing has been rendered as an ubiquitous technology that is active in the web's cloud, as if everything could be clouded and everything on the internet is cloud computing.
