Cloud computing: Find the North?

Recently, an IBM IT engineer published a web site called Cloud Computing: Is it really right for you? Article, let's see how large system vendors explain cloud computing to their customers. The content of the explanation is full of conceptual errors and misleading elements, which is at the opposite of the product idea that manufacturers are promoting to make decisions that help business managers smarter. Unfortunately, such errors often occur in such things as IBM, HP, Oracle and Http://www.aliyun.com/zixun/aggregation/11208.html ">microsoft, Accenture, Deloitte and other manufacturers in the promotion of cloud computing related concepts and the future development of the process. To give the reader a better idea of cloud computing, I'm here to sort out some of the misconceptions in the original text and fix it:

"Cloud computing refers to delivering it architecture components and services." "This basic definition of error makes the customer have a wrong understanding of cloud computing." This makes it natural for manufacturers to recommend expensive cloud computing platforms to their customers because they think they have to buy a lot of new products to make their data centers a standard cloud-computing architecture. To be sure, building a data center for cloud computing is not a simple task, so it is more necessary to listen to the views of multiple experts and consultants. In reality, however, many companies are buying cloud computing as a cloud application, because cloud apps allow users to immediately start using the appropriate resources based on pay levels without having to wait 18 months to compute requirements, design and implement projects.

The cloud pattern in the schema contains components that are client devices, servers, and data centers. "It doesn't even mention apps, although the next author mentions SaaS." Worse, this explanation is misleading for the original cloud frame composition. The original cloud architecture contains external services (such as X.25) that run on third parties. The point of the image is to show that the enterprise does not need to worry about the underlying hardware architecture because it is separate from the service.

"1. Is the return on investment greater than the loss?" Data center migrations can lead to confusion, increased costs, and complex situations. "Only a few paragraphs, we can see the author is to tell all readers, the choice of cloud computing is to move the enterprise's existing it to a new cloud data center, and this cloud data center is IBM really help the enterprise to build." IT administrators are particularly vulnerable to these words because they don't want to use a new, top-notch it device like Amazon. (Of course, a full replacement is not possible, because enterprise it has a large number of premium add-on devices, which [insert a global system manufacturer name] is known. )

"Some applications cannot run through virtual machines because such applications need to invoke the underlying hardware components." "It seems as if virtualization is an equal sign of cloud computing. Although traditional client/server applications, as well as legacy applications from the mainframe era, cannot be migrated to the cloud without modification, they should not be the first to say anything.

"Some applications require faster delivery speed, if delivery is delayed, it is best to keep this set of applications (including all system component Web, applications, databases, middleware servers, and so on) on the enterprise's local system. The author is hoping that companies will focus their global staff in the office next door to the data center, To achieve the corresponding speed of nanosecond level? Instead, the author wants the Enterprise to upgrade the network architecture (or a high-speed architecture product that selects a cloud service provider). Of course, traditional enterprise applications are closely connected to the application server and database, so it is best for the enterprise to maintain this close relationship. But any application that delivers services to a remote client or mobile terminal today should be upgraded if there is a delay.

"Businesses must accept the risk of handing their and their customers ' data to third-party storage." While large system vendors and security vendors are fond of flattering customers, the fact that most CIOs are now aware that cloud providers are providing a level of safety assurance is more secure than the company's own security.

"The last thing you want to see is the fact that your data is mixed with other people's data," he said. If your business is on the same floor as another business, if you send an email and if you use VPN via the Internet, wouldn't you be worried about getting your data mixed up with other people's data? Because when data is passed through routers, packets from different sources are mixed together. You don't have to worry because you know that the header of the packet is labeled to ensure that your data is not sent to other terminals. Cloud computing vendors are using a similar approach to differentiate between storage locations, making sure that your data doesn't mix with other people's data. Maybe your data will be on the same hard drive as someone else's data, and it will be done by the same processor, but it's quite different from the fact that the post office will occasionally make your mail wrong, and there's no need to worry.

"Under what circumstances should companies not use cloud computing?" after a misleading definition of cloud computing at the outset, the last paragraph of the article concludes with a summary of what the enterprise should not do with cloud computing. Without mentioning the "Why should we use cloud computing", nor does it cite real-world problems with cloud computing, such as how to combine the cloud with the enterprise's internal IT equipment. As a suggested article, the content of the text is not neutral, the concept of cloud computing is also fairly simple. But it's also a common problem for global companies, and no wonder people are confused about cloud computing.
