Broadband is not wide? Network bandwidth is the biggest constraint of cloud computing landing

Cloud computing has moved from concept to landing, making it the best choice for companies to find a way to transform data centers, but when companies are gearing up to deploy cloud computing on a large scale, they find that this is still an unimaginable challenge for today's network performance. As we all know, cloud computing may significantly increase Internet traffic, resulting in disruption of services, network latency and other problems will seriously restrict the development of cloud computing.

Although on the surface, the use of cloud services is simple, lightweight, convenient, but behind the consumption of a large number of network bandwidth. Have to admit that the network bandwidth is difficult to protect, become a constraint on the development of cloud computing "stealth killer."

Cloud computing service delivery relies on the network, low access network bandwidth and instability will make the performance of cloud computing is poor, which depends on the development of access network technology.

Cloud computing structure is the main feature of a global access to the resource structure, which means that the use of cloud computing structure of users will be across the WAN. How to solve the problem of network access effectively? For example, north-South interoperability, network traffic bottlenecks and so on. Because the network bandwidth is small, the user accesses a large amount, the net distribution is uneven, the problem that the user visits the website to be slow to respond is still to be solved.

With the spread of cloud computing technology in online games, cloud technology will use the network to reduce the number of PC computing to the user's hosting (through the network to share hardware resources). Although this may reduce the need for native hardware, it will greatly increase the ingestion of network bandwidth.

Obviously, all of the above are pointing to a word, that is, bandwidth.

Bandwidth is a measure of the network performance of an important standard, from the initial hundred trillion to gigabit to million, Ethernet in the gradual development of the process to meet the rapid growth of people's needs. And the cloud computing era, from the above we can also see that, with the enterprise class of a large number of applications and personal business increasingly to the network migration, hundred trillion access, gigabit backbone of the network structure has been outdated, the network is bound to rise a level of magnitude, gigabit access, million trillion backbone will usher in the trend

So we come to the conclusion that in the large-scale cloud computing environment, the performance becomes the core element which the operator most concerns, along with the cloud computing resources and the scale unceasingly expands, the network distribution which based on the 100G interface will become the large-scale cloud computing inevitable choice. And if the deep reason, as the China Electronic Society cloud Computing Experts committee chairman, Chinese Academy of Engineering Li Deii once said: "Broadband is not wide, the overall look is not a technical problem." "The government and the market are two hands in the development of cloud computing and need to interact with each other, but governments should not replace the market." The role of Government is mainly to guide, mainly serve, guide mainly embodied in the direction, planning, standards, regulation and incentives, services embodied in the management of environmental policies. The government needs to enhance the security and trust of cloud computing, of course, by technology, but more by regulation, and resources can be effectively and rationally distributed only if they are properly managed.

High enough, reliable, low-cost, easily accessible bandwidth resources, cloud computing industry is the premise and basis for the development. In China, the problem of insufficient bandwidth and high flow cost is restricting the development of cloud computing. At present, China's network bandwidth and the United States, Japan, South Korea and other developed countries are far from the gap. China ranked second to last in a survey of the bandwidth of 25 countries worldwide. By the end of 2010, China's broadband penetration rate was 33.5%, while in 2007 Europe's broadband penetration rate was 35.4%, while the US reached 50.9%. In terms of bit rate and structure rate, there is a big gap between China's broadband. In addition, the development of broadband in China also has regional imbalance, urban and rural imbalance phenomenon.

The core of cloud computing is based on the application of the network, the bandwidth of the access network directly determines the enterprise use cloud computing platform quality. For example, if each user uses the business at the same time to reach peak bandwidth, then the enterprise will have to face the network paralysis, business interruption. "If every broadband user is online and running full bandwidth, it's going to be a big deal," he said. It can be imagined that the problem of access bandwidth to cloud services will be how much impact. There is a media analogy, it is like the width of the highway directly determines whether the road is smooth or not.
