What is cloud computing?

There are more and more topics about cloud computing, and we often don't like the clouds. If you don't know what cloud computing is, or if you don't see the reason for the existence of cloud computing, you sound a good company. On many occasions, Gartner analysts say, cloud computing is just a new bottle of old wine.

When people talk about cloud computing, Microsoft CEO Steve Ballmer said in a recent appearance at Churchill Club, he means taking something out of the firewall, possibly on a shared server or storage system.

Oracle CEO Larry Ellison, according to Wall Street Journal, said at a recent analyst meeting that the computer industry is the only industry that loves fashion more than women's fashions. Maybe I'm an idiot, I don't know what people say about cloud computing. It's all nonsense, it's insane, when is this stupid?

The confusion comes from hardware and software vendors, according to Gartner, the company's analyst. Gartner's vice president and analyst David Smith says he thinks cloud computing is a new bottle of old wine, a buzzword that vendors expect to raise their product sales.

Ballmer and Ellison are not the only ones attacking the trend, and with the disappointment of continued growth in cloud computing, the Free Software Foundation, Richard Stallman, has also joined the criticism and, in an interview with the UK Guardian, has been particularly critical of Google's Gmail To criticize, he said, it is a trap to force people to buy a closed, dedicated system, and eventually people will spend more and more. Stupid, worse than stupid, he said, it's a kind of market speculation.

Should we blame the manufacturer?

Gartner Smith says he understands that Ballmer and Ellison criticize cloud computing as a rejection of software patterns that compete with themselves, but they are also a reaction to the confusion caused by the misuse of concepts.

In fact, cloud computing is widespread in a variety of products and services. Sell had attempted to register a cloud-computing trademark for its server products, but was rejected by the Patent and Trademark Office.

Microsoft and Oracle are not really respectful of cloud computing. Ballmer, who is participating in the cloud computing show, announces that Microsoft will develop a new Windows platform, Windows Cloud, to support cloud-based applications. IDG revealed that details of the Windows Cloud will be announced with the PDC at the end of this month.

At the same time, Amazon exposes their latest cloud services, allowing users to run Windows servers and SQL Server databases on their EC2 (elastic coumpute Cloud) service. Last week, Amazon and Oracle jointly demonstrated Oracle software that could run on EC2. These development efforts are part of the problem, Smith said. On the one hand, people have an impulse to put everything in the name of the cloud because it's fashionable. Vendors need these to facilitate sales, and IT departments need to add cloud concepts to their projects to get the budget.

Confusing "cloud-mode Technology" and "cloud computing services" also adds to the confusion, Smith added. How Dell's servers and salesforce.com CRM systems can all be called cloud computing is not the same thing. Instead, Smith recommends dividing them into cloud computing services and cloud-mode technology. Or use previously existing names, hardware and software.

More importantly, users should forget these buzzwords and ask themselves, what do I want? For client/server technology, e-business, and service based architectures, Smith's recommendations are the same. These are all new bottles of old wine.
