See the cloud of the past and present life

Recently, Forrester's survey of Chinese customers ' cloud Maturity index showed that more than 2/3 of respondents feared they would fall behind their rivals for not developing cloud computing, and 57% of the big companies surveyed had already started to deploy cloud computing. Everyone's consensus is that cloud computing is definitely the future trend of it, this general direction no one questioned, this also confirms the above findings, VMware Greater China technical director Zhang Zhenlen said.

According to Zhang Zhenlen, a round table attended by some time ago, with the technical elites from end-users, traditional it vendors and the Internet, discussed the development of cloud computing in China. There was a sympathetic view at the meeting, but there was also a clear divergence: The end users at the scene felt that cloud computing was still immature and they were in the exploratory deployment phase. The presence of it vendors feel that there is a mature cloud solution, can help users immediately launched the cloud computing project. And the view of the Internet guests is even more stark: 1 cloud computing is already very mature, they have been used for several years, why do people think she is immature? 2 Why don't we talk about Hadoop, MapReduce, GFs? Without these how to build cloud computing? This disagreement in my recent participation in the various cloud computing meetings have been repeatedly mentioned, it seems really necessary to explore the cloud of the past and present life.

Cloud computing originated from the Internet, today's cloud computing model works all in the Internet companies, including: Amazon, Google, Salesforce, Alibaba, Tencent and so on, and today's cloud computing is so enthusiastic, because of the traditional enterprise data center and IT vendors in trouble. After decades of construction, the traditional enterprise data center is facing more and more challenges, and the Internet set an example to let you see the traditional data center development in a new direction. But are traditional enterprise data centers really fast Internet? To answer this question, let's look at the difference between the Internet and traditional enterprise data centers.

The internet originated from the grassroots, basically through low-end hardware and open source software, two times to develop their own unique architecture to support their business. Their business logic is relatively simple and involves fewer links, and to some extent they solve the problem of scaling and availability and reliability of IT systems through an application pattern similar to HPC (High performance computing). Today we worship the cloud model enterprises have been through at least more than 10 years of accumulation, through the joint efforts of thousands of software engineers to create today we envy the cloud platform, and their use of tools and methods are we as the cloud of the Bible as the same view. This is why today almost all of China's cloud computing books and training are all about these model projects, and why the Internet industry feels that cloud computing has matured not a day or two, but several years.

and the traditional enterprise data center is a family of noble family, belong to the family. In the beginning, only large manufacturing, banks and so on can afford to buy computers, at that time the basic mainframe world. Later, although after decades of development, small and medium-sized enterprises often do not enjoy the enterprise-level data centers, because enterprise-class data centers rely on the mature products of it vendors, hardware and software are more expensive, even if some customized, still mainly business logic layer of the customer, the architecture layer is the standard of small machines, networks, storage devices, plus the standard operating system, database, middleware and other components. Although some customers are beginning to try open source Linux and so on, but still be packaged by IT vendors Linux, including Red Flag Linux, Suse Linux, Enterprise customers own development capacity is very limited, especially the bottom development capacity is almost blank. Traditional enterprise data Center to the cloud computing era, or to rely on these it vendors, without the support of these it vendors, rely on customers to build a complex cloud computing platform from zero, almost impossible to complete the task. And it is not hard to understand why enterprise customers feel that cloud computing is immature and still in the exploratory deployment phase, until only recently there has been a cloud-computing suite available to it vendors. Of course, it's not hard to understand why business-class customers talk about cloud computing, which is rarely about Hadoop, GFS, and so on, because it's really not their dish.

This shows that the enterprise-class data center cloud journey is absolutely not simple internet, fall into the internet Cloud Bible trap. Enterprise-class data center to go out of its own characteristics of the cloud journey, based on their current situation, to stand on the high enough to carry out the planning of the cloud trip. The urgent task is not to delve into Hadoop, MapReduce, GFS, etc., but based on its own reality, through virtualization to complete the pooling of resources. The results of the Forrester China Cloud Computing Maturity Survey show that 99% of respondents recognize the importance of virtualization, but it does take a while to complete the virtualization journey. Virtualization is the first step in a private cloud build, followed by the transformation of business models and process changes, and the corresponding it implementations. Of course, finally must go to the public cloud, and eventually form a mixed cloud pattern.

Let's look forward to the future of enterprise-class data center cloud computing.
