Talking about OpenStack Data Center Application

Cheng Hui is the founder and the founder of UnitedStack, the earliest promoter and practitioner of OpenStack in China. He will give an in-depth explanation of how OpenStack is building a cloud computing data center in the "Cloud Computing Core Architecture Forum" and bring the team over the past year Experience and Experience in the Process of OpenStack Productization.

OpenStack cloud platform as a cloud computing Linux, Internet companies, traditional enterprises preferred open source cloud platform. As the rapid development of cloud computing technology, traditional data centers are facing a new round of changes and upgrades. Using the open source cloud platform OpenStack is the most important choice for building cloud computing data centers.

Cheng Hui led a group of OpenStack engineers in early 2013, founded UnitedStack, and set up R & D center in Beijing to start the commercialization and exploration of OpenStack.

UOS (United OpenStack) is an infrastructure-based service (IaaS) cloud computing service and operation platform developed by the UnitedStack team based on OpenStack. UOS focuses on IaaS core technologies and capabilities such as elastic computing, distributed block storage and software-defined networking (SDN) Based on this, it provides virtual data center (VDC) services to provide customers with a secure, reliable and isolated infrastructure cloud environment.

Speaking of IaaS cloud services core technology, Cheng Hui talked about a few points:

Home to solve the storage problem, the core of IaaS storage components are distributed block storage, the service can be a significant role for the stable operation of the cloud host, such as the host can provide a secure online migration;

And then to solve the network virtualization, there is no mature virtualization network technology to choose from, no matter what the program needs to do a lot of research and development and testing in order to stable operation of a virtual network similar to AWS VPC services;

Third, IaaS infrastructure cloud service operation and maintenance and SLA service quality control. The so-called one-third of technology, seven-dimensional operation and maintenance, there is no strong operation and maintenance capabilities, and then powerful technology is useless. Different from SaaS type cloud service, the biggest difficulty of IaaS lies in the management and integration of hardware resources, service control of user SLA, and operation and maintenance of the platform. Open source OpenStack SLA control in the operation and maintenance management has been a weakness.

Finally, it is the cloud data center network architecture design, the traditional data center network architecture is difficult to support the business development of large-scale cloud service platform, especially the introduction of SDN network technology and distributed block storage services, high performance and flattening of the physical network The demand is more and more intense.
