"Editor's Afternoon Tea" a discussion on the cloud architecture of courtyard and building

In just four or five years, the cloud era has been unstoppable and has gradually swallowed and changed the original IT infrastructure, forming a complete cloud infrastructure service. But whether to move to the cloud, how to migrate, when and under what circumstances, many enterprise IT managers are a bit “ halo ”. As an observer, I have a lot of questions myself. This afternoon tea, my friend Zhang Zhenlen and I started a discussion on this topic.

Zhang Zhenlen is an industry-recognized expert in virtualization and cloud architecture, and has been interviewed by me since 2007 as the technical director of Greater China for VMware, Flash 8 years ago and now a technical director of F5 Greater China, becoming more professional in cloud infrastructure. Let me “ angry ”, his spirit is better than 8 years ago, I am obviously fat.

Topic one: From the courtyard to the building to move or not to move?

Our conversation begins with a metaphor.

A village, Lao Wang's first family lived in the courtyard for decades —— furniture is old furniture, draught has a well, cooking has a big stove, the days have been inverted also paste run. Say this day the village has built a modern residential building, all kinds of hardware conditions will be good, water and electricity is more convenient. To what type, hardcover or lite, can choose their own — village feel that living in the building convenient, comfortable can also free up land, call for everyone to move in. So, moving or not moving?

Zhang Zhenlen listened to the music and said it was a good metaphor. Indeed, traditional enterprise applications have been more than 10 years or more than 20 years of development, a variety of applications basic molding, this time you let him move to the cloud, the price is too great. In this case, it is neither realistic nor cost-effective for enterprises to forcibly move existing IT systems and applications to the cloud.

But Zhang Zhenlen also asked me a question:

If Lao Wang has a son to start a family on their own, Xiao Wang is to continue to live in the courtyard suitable, or to live in a suitable building? Also, if the old Wang home to a relative, is the right to live at home, or live in the village of the house is suitable?

Obviously, just like the head of Lao Wang can continue to live in the courtyard, young people and guests can directly live in the building, for enterprises, has been mature operation of the application, there is no need to migrate to the cloud, but some new applications, as well as some special circumstances (such as test environment, etc.) can be directly deployed in the cloud, Take advantage of the flexibility and low cost of cloud infrastructure. In other words, choosing whether to adopt cloud architecture based on business application driven,“ not cloud ”.

I asked: The new question came ——

if Xiao Wang and his relatives live in the village, the old king in the courtyard, then see a face to change things more inconvenient? Lao Wang Ping when pull things are old ox cart, always can not send anything all Daoteng down and put on the car? He can't drive!

Zhang Zhenlen explains that this requirement has always been there, and that there are more mature solutions —— virtualization technologies that are actually designed to solve this problem. And now a lot of enterprise applications, no need to all re-development, you can virtualize an environment, so that the original application continues to run up. Make an analogy ——

Lao Wang How to use the Ox cart. If you need to take something to find your son is not suitable for the road, let his son open a van, the ox cart directly into the back, a foot throttle not to it?

Topic Two: The deep changes of living buildings

One question that has been bothering me is the rise of cloud infrastructure, and what revolutionary changes have been brought about? This question I asked a lot of people, of course, it is difficult to find the standard answer, but everyone's perspective is different. In other words:

The number of people living in the building, in the end will give the village —— villagers ' life and even the village's ecological —— bring about what changes?

Zhang Zhenlen pondered, slowly said:“ I think it should be the cloud spawned the application of fission, the original application of large particles is the mainstream, is now being gradually cut loose. ”

This angle I didn't notice before, I slowly digest, basically understand his meaning: like ——

Each family's original furniture, utensils, basically are custom-made, generally rough and general, but the development of the building, resulting in the demand for the market number of increase and the function of each product, quality requirements more detailed, such as our furniture, electrical appliances, is derived from more and more subdivided products.

In other words, in fact, in the cloud architecture, many applications are gradually refined and perfected, can provide enterprises with a number of more, more functional application services, enterprises can also free up a lot of energy to solve how to provide users with better service aspects.

I asked: What do you think is the biggest new problem in cloud architecture?

The first is security, and the next is the challenge of application delivery, he says. He explained to me ——

Before each family is relatively closed, to the evening, the door a close, this home is basically not too much communication with the outside world, security is not outstanding. But now in the building, a lot of resources are public, the way of life has changed, the problem of security has become prominent. Therefore, it is necessary to install security doors, increase building monitoring and other security measures, in addition to increase the safety and so on.

In addition, as the quality of life improves, the functional and quantitative needs of each family's products are dynamic, and it is a new challenge to ensure that their needs are met quickly.

Then Zhang Zhenlen asked me a new question: Did you notice the changes in the purchasing process of traditional applications and cloud architectures? Look at me a little stupidly, he drew a schematic:

650) this.width=650; "class=" Fit-image "width=" 465 "height=" 231 "border=" 0 "src=" http://s3.51cto.com/wyfs02/M00/77/ 9d/wkiom1zqrpgsly9paabd8j0pba8951.jpg "/>

The lower-left triangle is the traditional IT investment. In other words, a large amount of enterprise costs in the communications network and IT infrastructure, but ignored the software and application input, such a structure is destined to be rough, but in the cloud architecture (upper right triangle), the communication network and IT infrastructure costs are greatly reduced, the enterprise's attention to the application itself has increased rapidly.

I think this summary is quite reasonable and helps him to summarize:

Before the courtyard life, a lot of money is spent on the purchase of land, built on the house, the real furniture, appliances have no money and no conditions to invest. Now the building era, the public facilities greatly improved, you can take less money, directly enjoy better housing conditions, and then put the money in the home decoration, furniture, electrical appliances and other improvements on the quality of life will be improved.

Topic Three: Do you live in an apartment or build a building yourself?

The advance of the cloud infrastructure is not a proposition to be discussed, and both of me and Zhang Zhenlen are recognized. The other thing that we think we don't need to discuss is the public cloud or the private cloud, and we quickly find that we don't need to discuss it: because we can't find the answer. If you still use the analogy, that is:

Lao Wang saw his son live good, but also slowly found the benefits of the building, but considering the security, privacy, and do not like ordinary residential buildings, it is tangled. This time the son gave him a new plan: Build a small villa, unique detached. Old Mr. Wang is a happy, calculate to find the problem: This may not be cheap!

This is actually the private cloud model. But it's important to note that the cost of a private cloud is not a public cloud analogy. The US CIA set up a cloud computing system in 2013, and Amazon beat IBM to get the deal, but it offered up to $600 million!

In this case, the hybrid cloud is a natural choice for many people. It is even said that the coexistence of the original IT system, public cloud and private cloud should be retained for a long time.

Conclusion: What is Service?

There have been many new words recently, such as SaaS (software as a service, software as a services), PaaS (Platform as a services platform as a service), IaaS (Infrastructure as a, infrastructure as Services). Undoubtedly, the key words in these words are “ services ”. In fact, the traditional platform, cloud architecture, how to help enterprise IT architecture and applications to enhance their business support capabilities and service level is the key. If we borrow the words of Internet products, that is how to improve the “ experience &rdquo of enterprise IT managers, so that CIOs can really feel the value of cloud architecture. This experience includes metrics such as traditional usability, security, and reliability, as well as the rapid deployment, flexibility, and ease of scheduling as infrastructure improvements evolve.

From the courtyard to the building, the final change is the life experience. To some extent, it also represents a kind of progress and inevitable trend. It architecture, as well.
