The road to cloud computing: confusion in the former pragmatic truth

From Kai-Fu Lee to cloud computing ...

Recently in the It circle, a very hot topic is between Fang and "Innovation Factory" CEO Lee Kai-Fu, the latter in their autobiography of some of the authenticity of the battle, the final result is that Lee admits his biography, on his 26 school in Mellon University became "youngest" The description of the associate professor was wrong, and it was not "rigorous" in the description of President Obama's classmate. The end result is that Kai-fu Lee was wrapped in the autobiography of Dazzling Halo, had to say to fade a bit. This can not help but make people feel again, people still have to be pragmatic.

From this incident to the same in the IT circle of the fiery "cloud", I think quite a bit of reference. In the case of Kai-Fu Lee itself, even if not false publicity, their knowledge and qualifications are quite good, and cloud computing itself, from the technical point and development experience, to the final ideas and models are also widely recognized. On the other hand, Kai-fu Lee was dubbed "Life mentor", "Young tutor", and its own default, admirers countless. What about cloud computing in today's it circle? "Future It" and "ultimate vision" are mesmerizing and countless followers. But when Kai-Fu Lee's Halo faded, I think cloud computing is also facing the same problem, each of us involved in the people, we also need to weigh the "pragmatic" people are still how much.

Kai-Fu Lee in the teaching of green admirers, often take their own brilliance, let the younger generation passionate yearning, and thus inspire their own trenin, in order to make the world different. And in the "touring" process of cloud computing, so too, it depicts a lot of good vision, attract you to go, but as Lee's speech, it does not tell you how to do for each student, but to tell you how good I am, and finally what kind of results and performance, in many manufacturers of cloud computing introduction, Most of the same, tell customers how much more advanced cloud computing, can help you save how much cost, realize how efficient business model. However, finally Fang told us that Mr. Kai-fu is not as good as he said, and he taught students the truth, in fact, there is no new, just to himself as a fresh example, let people more admiration and yearning. By contrast, the degree of education is far less than open, and the experience of working in a large company is not as good as jobs, and the achievements are much higher than the former, which means that each person's road to success is different, is different from the individual. Cloud computing is also the case, it is not really as good as it advertised, at least for some enterprises, so we also need a pragmatic heart, in the current glitz, to find their own enterprise, the best it Evolution (success) road.

If you want to use cloud computing, you need to choose Clear http://www.aliyun.com/zixun/aggregation/14032.html "> What is Cloud computing, but this problem is a fairly complex set of issues, and to elaborate on it, is not the purpose of this article. But what I want to say is, grab a few points and get a general idea. First, cloud computing is an IT service model or way, note that it is a service, this is a very important concept, we can spend money to buy things to imagine the same, common cloud is your enterprise it to buy IT resources outside (infrastructure, platform, application), The private cloud is your business unit that buys IT resources to it, and the hybrid cloud is a mix of two IT resources, the equivalent of a treat at home, a dish, a part of your home, a part of a restaurant outside, and your guest is the business application requirement. Second, cloud computing is not really a technology, it's an idea, it's more like a collection of technologies, so don't think cloud computing is so mysterious, it's related to technology, and there are a lot of these technologies that not everyone needs, so many times they don't need to worry about it, and they end up getting disoriented. Third, cloud computing has no formula, but there is a unified pursuit, now there are too many classifications for cloud computing, vertical, horizontal, many companies will feel that they are in the "fog", but here we have to grasp a point, the cloud in any case, to its target for the needs of the field, to achieve "dynamic provisioning, Automated demand response and efficient, flexible management to achieve lower TCO ", which is basically all the common pursuit of the cloud, but also should be the future of IT development of the enterprise pursuit." In this regard, our view is also clear--the advent of cloud computing, so that enterprises actually see a right, but also the inevitable demand-low-cost, dynamic, automated and efficient and flexible management. Aside from cloud computing, this should be the common aspiration of every IT manager, and the current hot cloud computing is just a model to implement it, whether we need the current major talk about the cloud, it varies from person to person. In other words, it is not important to be a postdoctoral student or to drop out of college.

The positive and inverse of cloud computing

In fact, every enterprise's IT environment is now more or less the shadow of cloud computing, for example, in the traditional IT architecture, the business department to the IT department of demand, in the current physical and isolated environment can also be achieved, is a long time, high cost, but you can not say that this is not a cloud computing service model, But the cloud is more evolved now. In the traditional way, to achieve dynamic, automated and efficient and flexible management, the cost will undoubtedly be very large, I think this is the biggest value of the current cloud computing.

But what makes it more confusing in China is that when many people think that cloud computing is centralized computing, cloud computing is distributed computing, cloud computing through the network to provide software services, virtualization in the cloud after the emergence of a variety of clouds, the large-scale cloud computing center is constantly on the horse, as if not to do cloud computing, will certainly lag behind. This hasty, swarmed "Chinese characteristics" in the impetuous behind, but also greatly beautify the halo of cloud computing.

In the final analysis, we need not to need cloud computing has no answer, each enterprise is a cloud computing environment, but not the same level of evolution, so this is like listening to the lectures of students of different basic and horizontal, can only large aspects of the truth understand, but specifically how to do? It's clear that you have to make judgments with your own needs and abilities.

Some people say that cloud computing must be virtualized, some people say the physical environment is also important, who is wrong? See application needs, not suitable for virtualization will not do, otherwise counterproductive. It's like arranging a 2x1.8 bed for Yao, and letting him sleep together and making it easy to build a joint.

Some people say cloud computing can reduce costs, some people say that using cloud computing more headaches, more expensive--cloud computing use or not depends on the specific application needs and environment, like a 4-port only need to buy a car on the line, you have to buy a large sedan chair spacious, you have to change your driver's license, but also to cope with the usual maintenance and super high oil money, Isn't this a blockage? So choose to see their size and demand, do what they can.

Some people say that cloud computing is easy to use, but some people say deployment difficulties-cloud computing involves multiple levels, especially at the application level for the traditional architecture to change more, we must confirm the work ahead of the transformation, just like to ride the bike of the fierce riding a tricycle, a few do not run away?

Some people say that the virtualization of cloud computing has a great impact on performance, and some people say that performance is good--whether it is virtualization, the performance is good or bad depends on the application of the load type, CPU, memory or storage I/O? To pour water into a small bottle with a funnel, or to refuel a barrel with a straw, you say painful? Targeted elimination of performance bottlenecks, whether virtualized or cloud computing is needed.

Cloud computing has many standards, a said a good, B said B Good, I said who good? -This is the truth, whether it is virtualization, or cloud computing application framework, there are many standards, but this phenomenon will exist for a long time, like programming languages, can not be avoided. According to the above, choose your one you think appropriate, the key point is the compatibility of the upper management platform, while taking into account the possible future with your choice of the public cloud standard docking problem, there is no better way.

The benefits of cloud computing There is a good say bad, I should listen to Which? --who would not listen, to weigh himself, but to be sure that the benefit was good, its enterprise it whether in the equipment selection, architecture design or in the enterprise internal management and process design is excellent, cloud computing can be said to be a whole transformation, like a fat woman to wear good-looking thin skirt, just to lose weight belly, the effect is not good, Only the body's symmetry for new Clothes (cloud computing) targeted weight loss (optimization) will achieve the best results.

Is my business suitable for cloud computing? I said, now the enterprise it can be said to be the original cloud computing model, as for the right is not suitable for the current publicity, this is a very need for the spirit of reflection, we must be pragmatic to look at this problem. But I'm not sure whether you need it or what your business needs are going to be, and if it's easy to handle, it's not necessary, if it's constantly on the go, and the business department is upset, then think about it. But to comply with resource dynamics (pooling, or virtualization)-the application of transformation (for cloud, Virtualization Environment Optimization and transformation)-Management automation (flexible response) A few steps to go, but not to seek fast, gets.

In short, cloud computing is a good thing, but it's not so good for everyone, therefore, it must not be deified, in the actual observation, research, deployment and implementation process, all need to take a pragmatic heart, at all times with their own needs and practical application scale out, to constantly examine their own way of cloud computing. And only when we continue to pursue the "cloud" of the "light" is not so dazzling, we will be more clear to see the road ahead ...
