Internet self-revolutionary road

Do not know how many people remember the need to download the phone line and the speed of only 5KB / s day, now the "big picture to kill the cats," the time has come away from us. As the domestic Internet has grown greatly since 2000, the Internet has changed from a new-born thing to a daily familiar thing, but in fact it generates more energy and influence than what it seems on the surface. From the IT industry as a whole, the concept of hyped cloud computing, big data, BYOD, socialization and mobility are closely related to the development of the Internet and the mobile Internet. Therefore, even some people think that the Internet is about to revolutionize IT's life.

This sentence is not entirely alarmist. In the past, the traditional industries swept by the Internet, whether it is music, media, books, home appliances retail, etc., have undergone tremendous changes in the business model and industrial form. It is not uncommon for industry leaders to make a big move.

Although the IT industry sounds more sophisticated and has a higher technological content, the same is more affected by the development of the Internet. In particular, the rise of foreign Internet giants such as Google, Amazon, Facebook and other open source alliances and projects, such as ONF (Open Network Foundation) and Open Compute Project (Open Computing Project) The progress is being changed by the IT equipment manufacturers dominate the technological innovation situation.

Take Cloud Computing and SDN (Software Defined Networking), the two hottest terms in the past year, all of them for the Internet, the earliest practitioners of which are also Internet companies.

Clouds from the Internet

The concept of cloud computing was proposed by Google engineers in 2006, and the concept was proposed based on Google's own IT infrastructure needs. Amazon, the earliest Internet company that opened e-commerce sites and later became the imitator of many domestic e-commerce companies, has made a big contribution to the development of cloud computing industry. So far, Amazon is still the largest public cloud service provider in the world .

The fiery cloud computing also sparked a debate over the IT business model, whether the traditional licensing model would be subverted by the cloud model of on-demand delivery of resources across the network. If all future computing and storage resources come from the cloud, IT departments there is no need to exist?

Everyone can "IT", so that complex construction, maintenance work to the cloud backstage, we only need to buy cloud services, no longer need to have IT equipment. Those cloud service providers eventually chose to develop their own software and hardware devices due to their large scale, rapid growth in business and technology (Google and Amazon have started to do so, and the most famous one in China is the IOE campaign initiated by Alibaba.) So, we are now into a state of 45 degree angle looking IT giants ... ... I am afraid that the prospects for the future.

Of course, the ideal is very full, the reality is still a sense of bone, the cloud computing is still there are a variety of universal crisis, the user's cloud of trust, cloud service instability and low performance, etc., all allow traditional IT vendors breathe temporarily . Although there are a large number of domestic cloud banner providers, but the publicity stunt is greater than the real, really reliable cloud service providers are not many (some people may think there is no). Even the development of more mature foreign cloud services, will face application limitations.

One of the main advantages of cloud computing is its low cost. Some start-ups adopt cloud services and can get enough computing resources at a low cost to meet their needs. They can also expand on demand according to their business volume. However, when they reach a certain scale of enterprises, It may find that the cost of the cloud is no lower than self-built infrastructure and may even be more expensive. At the same time, some of the business's key business applications, such as databases, do not seem to fit in the cloud.

However, these are hardly any permanent obstacles to the cloud. Simply put, it's hard to resist the temptation to get the information and resources you need online anytime, anywhere, whether it be public cloud, private cloud or hybrid cloud. The twists and turns in the process of controversy. The traditional software and hardware vendors have to do a good job preparing the cloud war.

Internet companies blitz SDN

Another hot speculative SDN, although there is no "cloud" in the name, but now it is more foggy than cloud computing. For what the SDN is, everyone speaks. The current mainstream technology routes include ONF's Openflow protocol, IETF's standard network open, ETSI's NFV (network functional virtualization), and Nicira's Overlay.

OpenFlow was the earliest proposed SDN protocol, also the most well-known, and some even completely equate SDN with OpenFlow. Openflow's proposal is closely related to the concept of the next generation of the Internet. It intends to separate the forwarding layer from the control layer. The switch is only responsible for data forwarding. The control layer is handed over to the enterprise. By providing a programmable interface API, definition". Need to be mentioned is that the creator of Openflow later built Nicira company mentioned above, Nicira was acquired by VMware.

Internet companies once again become the first to embrace a group of members of Openflow, Google Data Center in 2010 began to introduce Openflow for data center interconnection between, by 2012, Google's entire data center backbone network fully adopts Openflow. Google believes that Openflow has greatly increased the utilization of network bandwidth for better traffic control and routing planning. Domestic Internet companies, such as Tencent, are also actively researching and implementing SDN.

The hardest part is self-revolution

Internet companies so lead the trend of the industry, people feel grabbed the jobs of traditional IT vendors, no wonder the "Internet gene", "Internet thinking," these terms become particularly hot, we bowed to say: "The Internet has more than just a Kind of tool, but a way of thinking. "

As a matter of fact, instead of keeping up with the trend of thinking, it is better to say that traditional manufacturers occupy a large share of the market. If technological innovations are needed, they must reform their own lives. This obviously is not something courageous for ordinary people. But do not wait, do not you see the Internet has been challenging the financial, if not like the financial sector as a policy barrier, but also please weigh their own.
