Network virtualization solutions for future cloud data centers

Every time you talk about virtualization or cloud computing, administrators will invariably complain: "Data center network can not keep pace with the development of cloud computing." Data center computing and storage capabilities have improved dramatically over the past decade, and the network is still using the architecture of the past, and has not been able to keep pace with this evolution. With the rapid development of cloud computing and mobile Internet, there is a growing need for companies to significantly improve their data center capabilities. "

Why we need network virtualization

The traditional three-tier architecture is collapsing under the new world of big data and cloud computing, and sophomore technology is becoming popular. After the hardware devices in the datacenter are virtualized, further logical pooling can be made, and the logical resource pool can provide virtual data center to the user on the logical resource pool across multiple data centers, thereby bringing together discrete, layered, heterogeneous data centers into a new cloud data center. From this perspective, the virtualization of the network becomes absolutely necessary to provide an engine of resilient and scalable workloads, rather than managing the connections between discrete physical components alone.

In essence, network virtualization is the natural and necessary evolution of server virtualization. It allows the entire datacenter to be managed as a computing and storage resource, to meet the load requirements of dynamic application work.

What kind of network virtualization is suitable for future cloud computing data Center?

SDN's proposal provides another way to solve the problem. However, SDN only solves one part of the problem and does not solve all the problems existing in the current network:

Issue 1: Functional scalability: To achieve the software definition of network functions, the device infrastructure will be flexible and programmable, while the flexible extension of functionality requires an open and flexible controller platform architecture.

Problem 2: Smooth evolution: Any customer, it is impossible to completely discard the existing network, to build a new network. The next generation network must be able to deploy directly in the current network, smooth transition, can survive. This requires controller to have an open north-south interface to adapt to traditional networks.

For future cloud computing data centers, network virtualization solutions need to adapt to the wave of computing and storage virtualization, rapidly deliver cloud computing services, and meet dynamic application workloads, as well as help administrators manage physical and virtual networks more simply and achieve network visualization.

Openness is also a measure of the perfect network virtualization, only to provide a rich North-south interface and open API, and to meet the industry's mainstream cloud platform docking requirements to meet the rapid development of cloud computing business, while openness also means that can develop different plug-ins to adapt to the existing network, In order to realize the smooth evolution of the network.

Huawei Agilecontroller How to build a future-oriented network virtualization solution

Agile Network is the next generation network solution that Huawei Company publishes to Enterprise market. It is based on SDN thought plus three architectural innovations, so that the network can quickly and flexibly for business services, so that enterprises get four times times the pace of business innovation, to help enterprises in the fierce competition to gain the opportunity.

Agile Network Controller Agilecontroller, intelligent data Center brain

Huawei Agile Controller (Agilecontroller) aims to build a simple, efficient, open cloud data center network for customers, cloud network integration, support the rapid development of enterprise cloud business, so that the data center network more agile for the cloud business services.

First: Business efficiency, the realization of automatic network resources quickly distributed

In cloud computing, storage and virtual machines have been automated to implement on-demand applications, Huawei Agilecontroller can achieve voluntary network automation distribution, application of network resources as easy as the application of virtual machines, efficient network automation so that the cloud computing business faster online, greatly reducing the cycle of business online.

Second: Operation dimension is simple, let the virtual and physical network cooperate to control

Huawei Agilecontroller can realize the coordinated control of physical network and virtual network, and support the unified management of physical resources and virtual resources (physical network, virtual machine, Virtual Switch, distributed Virtual Switch, etc.) through network visualization to make management simpler, and greatly reduce the management difficulty of administrators.

In the data center network, there is also an important problem is the virtual machine migration problem, Agilecontroller can realize the network policy automatically adapt to high-speed migration, Unlike other virtual machine network policy migration schemes in the industry, agilecontroller the network strategy through the high-speed RADIUS interface, which makes the network strategy deployment speed increase greatly, reach 10-20 times of the industry, can meet the needs of the huge virtual machines in the data center. With Huawei's rich sophomore-tier network solution (TRILL/EVN, etc.), VMware virtual machines can migrate within the data center and across data centers, with more flexibility in cloud business deployments.

Third: Open, with the mainstream cloud platform docking

Agile networks are defined as a network of hardware, a software definition network, and a fully programmable system. Huawei Agilecontroller provides rich north-south interface, open API, realize the forwarding surface and control surface programmable, with the customer's existing equipment and business system docking, improve end-to-end operational efficiency, speed up the new business online speed, and create a rapid innovation environment for enterprises.

The industry cloud platform multitudinous, the mainstream cloud platform has Huaweifusionsphere, VMWAREVCAC, OpenStack and so on, the Huawei Agilecontroller all supports with its docking, is committed to creates a flexible, the open platform, integrates each domain the outstanding practice, Allows users to flexibly define the network according to the needs of the business.

We have no doubt that the data centre has developed rapidly. How does the infrastructure support this growth? Virtualization is just a part of it. Future networks may need more features. In many features, how to choose to build their own network? At present, Huawei's agile network, that is, absorbing the essence of SDN, while considering the smooth evolution of the existing network, Agilecontroller simple, efficient and open, for the successful construction of the future network has laid a solid foundation.

Cloud computing makes web apps exciting, making application innovation easier; The web is the cornerstone of cloud computing, without the network there is no cloud computing, the development of cloud computing has put higher demands on the network.

Agile controller Agilecontroller emerged, its appearance simplifies the customer's cloud platform to the equipment operation difficulty, now has the Agile controller Agilecontroller, the automatic middleware can assist the user to manage the equipment. At the same time Huawei Agile Controller is an open platform, the Agile controller will be opened to the North-south interface, so that industry customers an open custom space, with partners to build agile business practices, so that they are more concentrated in the business transformation and transformation, but also the cloud of ICT integration management to truly achieve, Dramatically improve the deployment and management of cloud computing, so that the physical network and computing storage resources, as part of the cloud, network and computing synergy, mutual visual, make cloud computing simple.
