H3C: A rainy day to meet the network challenges of large-scale cloud computing era

Compared with it enterprises and internet companies, the biggest advantage of operators to expand the cloud computing market is the network basic resources. But now, the massive deployment of cloud computing is quietly challenging network performance and IT management beyond imagination. Looking at the different requirements of cloud interconnection, cloud interconnection and cloud interconnection under cloud-ready background, the traditional single network technology scheme is bound to differentiate and optimize and integrate with different network function characteristics and customer groups. Whether it is a data center or a base-hosted network, the face of cloud computing has issued a "new generation" call. "Operators do cloud computing, the network must first take into account the rapid growth of cloud computing in the next 3-5 years, or it will be a huge challenge to the existing network," said Sun Hui, H3C's carrier solutions minister. ”

Operators swinging their chest and cloud

Cloud computing contains a lot of business, many levels, different vendors, different operators in the minds of cloud computing is not necessarily the same thing. Sun Hui that operators should combine their own characteristics to develop the most suitable for their own cloud computing model.

Internet companies ' cloud computing is more about providing SaaS services to a huge number of individual users, a model that is already very mature and has a very large scale of cloud computing. For operators, more advantages are in the network and computer room and other basic resources. If cloud computing is considered a resource "pool", the water in the pool is applied to tens of thousands of users, and the "pipeline" between the pool and the user is very important. Operators in this information infrastructure to control the "pipeline" transmission, it is very suitable for the first infrastructure-level cloud services. The three major operators IDC room in the country has more than 700, the business has been to a considerable scale, but the previous IDC like to do as landlord rental room space, now a little flexibility can be the basis of the cloud services evolution. The Network service quality determines the IDC room price high and low, the resource bottleneck still lies in the network.

Operator provincial companies have many successful cloud computing implementations, and are now generally moving from easy to difficult. One is the integration of internal business systems, IT system construction resource pool, first of all, to achieve private cloud computing, to reduce costs, training cloud computing business talent, the current provinces have the basic plan. In addition, it is aimed at enterprises and enterprises major customers, the group of major customers, to provide government cloud, industry cloud applications. As the core of the future Information Service system, cloud computing provides a historic opportunity for telecom operators to transform from the communication industry to the big ICT industry, and also provides the opportunity for the telecom operators to switch from "pipeline" owners to "end-to-end" business providers. Operators have been doing integrated business before, but they face a lot of fierce competition from it integration companies. After operators rely on cloud computing, it is possible to change the pattern of the market, because cloud computing first requires scale and service. This time the operator's advantage can be revealed.

Recently, operators have increased the investment in cloud computing infrastructure, China Telecom invested nearly 1 billion in Chengdu to build a super five-star "Western Information Center", will be able to accommodate more than 3,500 standard racks, storage capacity of not less than 1000PB, export bandwidth up to 1Tbps, is currently in the domestic production of the largest IDC. In the next three years, China Mobile will invest more than 10 billion yuan in building cloud computing data Center in Hohhot, Inner Mongolia. Sun Hui that the purpose of the operators ' construction of the mega-data centers is to focus on the competition of resource scale, but in addition to considering the factors such as location, climate, land and electricity, we should consider whether the network resources are sufficient and the network needs to be reformed with the scale of cloud computing business.

New generation of Internet cloud

"Scale determines the evolution of the network," says Sun Hui, "The capacity of the data center is limited and the new network architecture should be used to support larger data centers and to support the larger cloud computing scale." ”

Over the years, cloud computing has been more challenging in terms of servers, storage, software, and management, from a small cloud. Some of the fundamentals of cloud computing come from the IT industry, where previous systems in the IT industry are usually small. But the operator's user volume is tens of millions of, hundreds of billions, compared with enterprise-level cloud computing, the biggest feature is the scale is very large. Although the operator inside also do private cloud, but the final positioning is to do cloud computing service provider, the future competitor is like Google this magnitude, must be to achieve large-scale cloud computing costs only low, economic efficiency, service is better. Sun Hui that the size of the network, whether it is a data center, or backbone and metropolitan area Network, the network will first face a huge impact on the volume of business.

Based on the cloud computing perspective, H3C will be divided into three kinds of network, cloud Intranet, cloud network and cloud network. Cloud intranet refers to the network inside the data center. Cloud network refers to the network between multiple data centers, which is the network connecting from the user side to the entire cloud computing platform.
