Huang Coujun: Cloud Computing Architecture planning practices

In the 2011 China Cloud computing and Cloud Services Summit Forum, Huang Coujun, the architect of the Cisco Data Center and Virtualization Solutions Division, made a speech with the theme "Cloud Architecture planning practices" as follows.

First of all, I would like to thank the leaders and the guests for listening to me about Cisco's understanding of cloud computing and the introduction of some practical experiences in cloud computing.

My main content today is divided into three aspects, the first one to talk about Cisco's understanding of cloud computing. Second, Cisco's infrastructure planning for cloud computing and the introduction of related solutions. Third, Cisco's experience sharing in the field of cloud computing.

First of all, we see the traditional information architecture model, enterprise development process will face such problems, in the final analysis is mainly two aspects, one is the time is money, for our business development, we have to develop the business as soon as possible, and then on-line, promotion, so that the first occupation of the market, attract more users, In this way, the development of enterprises can bring more benefits.

For it, if the business is supported on the line, for the time required, how we deploy these it infrastructures, how to allocate.

2nd, efficiency is money. Affected by the economic crisis, enterprises are discussing the return on investment, we try to spend less, more work, can support more business development, so that for us it is to improve the utilization of the entire IT resources, while reducing management costs, focus on management, so as to save costs, improve the investment return of enterprises.

When we encounter these problems, we are also trying to solve some problems in different enterprises, such as trying to use the integrated approach to run it mode in a virtualized way, such as a service architecture, to solve some of the problem. Cloud computing will mention these solutions to a new height, cloud computing pushes it as a whole into the business sector, making it a fundamental change in our IT operations and deployment patterns, enabling users to access anywhere, anytime, anywhere, and to easily change these architectures.

For different enterprises, such as traditional enterprises and Internet companies, the basis of the different, the road to cloud computing will be different. Now the Internet enterprise has many new business, can adopt many new architectures, many innovative architectures, for the public cloud structure, can provide the cloud service for the enterprise. Many traditional enterprises, our basic structure has been developed to a certain extent, it is impossible for the cloud to abandon the original structure, we have to step in a steady way to build.

Our use scenarios have changed radically, and users of cloud computing have chosen the IT services they can reach through the portals, which make services available to users, who pick IT services, see what IT services they receive, what service levels they receive, And what the costs are to be seen for these levels of service. He can choose the services he needs, these services are clearly marked, and the cloud administrator will approve your request, including server resources, storage resources, network resources, and related security policies, as well as policies that include network traffic management, because these are all closely related, So the relevance of these resources must be deployed through unified management. Once deployed, the IT resources assigned to you will go into a lifecycle management that will be monitored, monitored, and monitored for changes. Monitoring has two benefits, one is for users to make some suggestions, cloud computing service providers can sell cloud services to you. At the same time, the cloud services for these service providers is also the accumulation of knowledge, can be used by users of the characteristics, will go to packaging some new services, new products to provide customers, this is two-way.

Of course, in this use, the Cloud management platform also provides a number of reports that can be provided to the management team to let you know what the status of the use, such as the cost of what kind of situation, can also provide visual reports, but also can give feedback to the cloud computing environment managers, It will give you an idea of how the cloud is used. In the cloud, we put it as a service, the entire it packaged into services to the user, our business model has undergone a fundamental change. And it has a related impact on all architectures. For our service providers, the core concepts of cloud computing, such as our service providers, the private cloud and the public cloud, have changed, so that they can be pushed to the needs of the users and create real service values. You can see that all of these resources will become standard pools of resources that can be extended in accordance with certain rules, where applications are connected through the network as a link to provide high-speed, secure access to the network. The development of these resource pools makes the basic architecture relatively independent and can be built and developed according to its own law, making the infrastructure construction more predictable and better in the future. For users, the original needs of the service through the way of service, through the way of service, can only care about your application how to achieve, how to achieve business. I very much agree with the view of the associate dean of the Research institute that the change of business model is a change, and the fundamental changes have taken place in our mode of operation and business operation. All of these changes are supported by core technologies that will enable these transformations to be achieved. The core technology of cloud computing is virtualization, virtualization is to do the different virtualization of these resource pools, the virtualization of cloud computing is different from the ordinary virtualization, is the original of these different kinds of resources to do a unified virtualization, our computing resources to do a perfect fusion. Cloud can see resources through the network can be accessed anytime, the network is computing, computing is the network, only to do this, so that can be more flexible. At the same time, many of our resources are shared, security is what we want to consider, cloud computing security considerations are very important. In addition, the relationships among the components in cloud computing are getting tighter, including computing, storage, networking, and so on. We need unified management, unified deployment to manage these resources, to achieve a complete cloud computing architecture operations and deployment.

This is the architecture of Cisco's next-generation data center, more in favor of the network, in terms of architecture, and the original architectural Foundation is consistent, the core point is that these technologies and devices are cloud-oriented technology, will support the development of cloud computing. The process of moving to the cloud requires constant evolution, not the process of revolution, in which case the investment risk to the user is relatively large, so through gradual evolution, the process of cloud computing is easier to achieve, but also more easily meet your investment needs.

Data Center architecture can be unified network architecture, unified to do virtualization, unified management, unified computing, and to achieve flexible interconnection. Unified network architecture, such as it Network and storage network integration, unified virtualization from server to storage to compute resources virtualization, deep into the virtual machine inside. Unified computing, in the cloud can see all the nodes have certain characteristics, as far as possible to make flexible deployment, we will be required to extract the feature points from the centralized deployment, to meet the future characteristics of cloud computing. Data center interconnection is very important, now everyone is talking about disaster preparedness, many domestic large financial enterprises are talking about the construction of data center, finally to integrate into a distributed data center, resources can be deployed, this is the need for data center interconnection as a support. There is also the management of cloud computing. Just talked about a lot of components in cloud computing, these components are more and more closely related to the distribution through unified command leveling, so that can be very flexible switch. Tidal is a Cisco solution that can provide an open service interface.

In the cloud computing environment, all of these users are in the form of tenants, is a high input, especially for the public cloud users, because in the public cloud, different tenants, leasing these virtual servers, the security control between them, including the data plane, as well as management control, The use of these users to hire is a big impact, if not meet such needs, may have a great impact on the use of cloud computing.

Cisco is the industry's leading provider, computing resources and network resources in the cloud computing needs to be integrated, Cisco many technologies are based on the network to do, the current product line to expand into the computing field, considering the needs of computing and network integration. For cloud computing Solutions, Cisco, EMC, and VMware form an ace Alliance, a packaged cloud computing solution that includes Cisco's computing resources, network resources and storage resources, and how to virtualize the operating system, Packaged together to provide a complete solution for cloud computing construction.

Virtualization can greatly reduce operational management costs, including hardware and software investments. Cisco provides End-to-end desktop virtualization solutions, Cisco also has related desktop virtualization end products, such as the ipad, Cisco out of a tablet computer, desktop terminal equipment can be provided to the enterprise to use, a unified computing environment, to provide users with solutions. The middle is the virtual network, this is Cisco's imagination, on the far right is the data center, the new business of Cisco, which has ranked second in the United States, ranked third globally, and has many advanced technologies to better support desktop virtualization.

This is Cisco's overall desktop virtualization program.

The value of cloud computing, we conclude that there are basically two points, for users can be more flexible, this is one aspect. The most important point is that the user experience you get should be the same as the user experience that you used to have, security is not missing, this is not the ultimate goal of cloud computing, I hope that resources can be shared. For service providers, resources can be used more, to the service provider is also the embodiment of value.

Let's talk about Cisco's practice in cloud computing. Cisco is also a multinational enterprise, there are many data centers around the world, it is also faced with the same problems, such as the business on-line time is longer. Cisco began its research on cloud computing in 2007, believing that cloud computing would benefit him by deploying the planning and construction of our data centers in the form of cloud computing.

Cisco implemented such a plan, called Cisco it flexible infrastructure, before implementing this service, many of our processes are the same as the current enterprise, through manual deployment, resulting in higher costs, and deployment time is also relatively long. Before our deployment time will take 6-8 weeks to be able to on-line a set of systems, the cost is high. After this project, all deployments are done in a self service manner, which lowers costs while reducing management and operational costs.

This is phased implementation, the first phase of virtualization technology, the use of some of the virtual machine technology, from the server to the traditional server approach to do, after the first phase of the overall cost down 30%, through virtualization. Virtualization achieves 50% of the entire architecture, reducing the deployment time from 6-8 weeks to 2-3 weeks. After the implementation of the second phase, more virtualization technology, such as the degree of virtualization reached 70% such a goal. After this phase has been achieved, some of the cost of investment has been reduced, which can be seen after the implementation of this phase, the deployment time from the original 2-3 days to a few 10 minutes, including such as network, security policy and so on. After implementation, the next four years can save 90 million dollars in cost, for storage management, our management capacity from the original 2.1 cents to 1 cents. The ultimate goal, we virtualize to do more than 80%, the overall deployment time to shorten to 6-12 hours, can be quickly deployed.

Cisco's architecture underpins all of the IT needs of Cisco's employees, and many people now have an iphone that can push e-mail to the iphone, which can be viewed anytime, anywhere. Now let's go to the flexible virtual architecture We just talked about, and many of the services are spontaneous. Cisco's adoption of the cloud computing environment is a big change for our business.

Today, I talked to you about Cisco's understanding of cloud computing and some solutions to cloud computing, and we want to introduce our own experience to users and partners to make some contribution to the development of cloud computing in China. Thank you!
