Initial exploration of the hottest Huawei dual act

A preliminary study on Huawei's dual active government cloud solution

computing is a new business form that promotes the supply of information technology capabilities on demand and the full use of information technology and data resources. It is a major change and inevitable trend in the development of information technology. China attaches great importance to the innovative development of cloud computing and strives to take the lead in the new generation of computing. It has successively formulated and issued the notice on doing a good job in the pilot demonstration work of innovative development of cloud computing services (fggj [2010] No. 2480), the 12th Five Year Plan for national e-government (gxbg [2011] No. 567), and The opinions of the State Council on promoting the innovative development of cloud computing and cultivating new business forms of the information industry (GF [2015] No. 5) and other guiding documents encourage the application of cloud computing technology to integrate and transform the existing e-government information system, significantly reduce the number of self built data centers, accelerate the development and innovation of e-government, achieve cross system information sharing and government collaboration, reduce repeated waste, and avoid fragmentation and information islands

at present, most provinces, prefectures and cities have carried out government affairs cloud construction, horizontally integrated the scattered it resources of various committees, offices and bureaus, realized the transformation from traditional chimney mode to cloud mode, and achieved good results in intensive construction, resource sharing, investment saving, etc. However, a large number of business systems are centralized in one data center, whether it is the operation department or the management department, and the risk may be more significant. Once a fault occurs, its impact range is several times or even dozens of times that of the original, and the resulting losses also increase sharply. Based on this background, a single data center, no matter how much it costs, cannot meet the needs of business continuity

based on the above considerations, Huawei has launched an end-to-end dual active government cloud data center solution, which can meet the business continuity needs of the government industry by means of two running data centers simultaneously undertaking production business, and improve the overall service capacity and system resource utilization of the data center.

the dual active data center solution is a very complex system level solution. To achieve real dual active, It is necessary to consider the requirements of the storage layer, the computing layer, the application layer, the network layer, the transport layer and the security layer. The common practice in the industry is that a manufacturer at a certain level gives solutions based on its own products. These solutions have more or less problems due to various factors, which makes it impossible to achieve real dual activity. However, the solutions of the system integrator are The key layers such as security and transmission adopt products from multiple manufacturers, resulting in complex product matching and many problems that cannot be verified before sales. In addition, after encountering problems, the product suppliers have a serious phenomenon of mutual prevarication and wrangling. Therefore, few integrators are willing to do dual activity solutions. Huawei has its own mature products at the key levels of storage, computing, networking, security and transmission. With the mature database RAC technology in the industry, it can achieve real end-to-end dual activity. At the same time, Huawei has optimized the dual active applications on products at all levels, which not only improves the performance, but also reduces the integration complexity

at present, the industry has two forms of supporting dual activity for waste paper and paper prices: AP dual activity and AA dual activity have been developing for too long. In the first form, AP dual activity is used to classify the services. Some services are based on data center a and data center B are hot standby, while some services are based on data center B and data center B is hot standby, so as to achieve the effect of similar dual activity. In the second form, AA dual active is a real dual active. All i/o paths of the same dual active Lun can be accessed at the same time. The service load is balanced and seamless switching can be achieved in case of failure

Huawei dual active government cloud solution adopts AA dual active architecture, based on the industry-leading oceanstor V3 hypermetro function, and combines with web, database cluster, load balancing, transmission equipment, network and other components to provide customers with end-to-end dual active data center solutions within 100km, so as to ensure that in case of equipment failure or even single data center failure in the business system, the business is insensitive and automatically switched, RPO (recovery point objective) =0, RTO (recovery time objective) =0 (RTO is related to the application system and deployment method)

the end-to-end dual active government cloud solution is divided into six layers: storage layer, computing layer, application layer, network layer, transport layer and security layer. The logic architecture diagram is shown in the figure

Huawei's end-to-end dual active data center solution is designed and optimized for each layer in order to achieve better reliability, performance and load balancing. For example, in the storage layer, the hypermetro function of oceanstor V3 array is used to realize dual active storage layer, reduce program failure points and avoid i/o performance bottlenecks related to storage virtualization; In the network layer, evn technology of Huawei cloudengine series data center switches is adopted; In the security layer, Huawei USG series provides FW, IDS and other security protection functions of the data center; In the computing layer, Huawei fusionsphere and other virtualization platforms are used to provide cross data center scheduling technology to meet the needs of enterprises in a variety of aspects. It is suitable for the dual activity of large pull key services; At the application layer, web and app applications provide better reliability based on virtualized clusters, and realize automatic business switching through load balancing; In the transmission layer, three 1+1 protection schemes, i.e. line redundancy, board redundancy and equipment redundancy, are adopted to meet the multi-level reliability requirements. At the same time, in order to meet the performance requirements of dual active applications, the protocol among storage, transmission and computing is innovated and optimized. For example, adaptive modifications are made on storage and transmission devices to reduce the delay of storage replication; The protocol interaction between server and storage is optimized, and resources are accessed nearby to improve IO efficiency

at present, Huawei dual active data center solutions are widely used in medical, energy, finance, transportation and other industries. In the E-government industry, Huawei has provided Ningbo with a government cloud dual active solution, created a stable dual active government platform, and helped make a new leap in smart Ningbo. Looking forward to the future, Huawei will also provide customers with more stable and convenient business continuity protection solutions through continuous technological innovation and unremitting practice in the data center disaster recovery field
