Industry Solutions
Electricity is an important part of the energy industry, which is related to the people's livelihood and a strategic supporting industry of the country. With China's economy continuing to grow steadily, China's demand and consumption of electricity are increasing day by day, which poses higher requirements and challenges to the technical, managerial and operational levels of the power industry. In recent years, the State Grid Corporation has actively promoted informatization and smart grid construction, closely tracked the development trend of "big data, cloud computing, Internet of Things, mobile" and other new technologies, proposed the construction of a "one platform, one system, multi-scene, micro applications" large information platform, launched key technological research, and laid a solid foundation for the sustained and innovative development of a strong smart grid and "one strong three excellence" modern company.
The State Grid information technology planning clearly proposes to build the State Grid cloud. The State Grid cloud includes three parts: enterprise management cloud, public service cloud and production control cloud, which are composed of an integrated "State Grid cloud" platform and its supporting various business applications. The State Grid information technology infrastructure architecture has completely changed from traditional IT architecture to new cloud computing architecture.
In recent years, the focus of power enterprise information technology construction has changed from "heavy construction" to "heavy management"; management ideas have changed from "managing infrastructure" to "providing services"; operational models have changed from "passive services" to "active services"; more and more management and services are based on network platforms. How to ensure that all management and business systems provide services without interruption while giving visitors fast content delivery has also attracted more attention from managers.
Secondly, the number of State Grid's cloud business systems is increasing, and the scale of the cloud is constantly expanding. The interaction between business applications is becoming more frequent. Currently, there are more than 1300 production business systems deployed on the State Grid cloud, and the complexity of the data center is getting higher and higher. This poses higher requirements for the reliability and agility of the State Grid cloud infrastructure.
Hongji SuperAD application delivery products provide fast, secure, highly available and flexible intelligent solutions for electric power enterprises. Within the power dispatch network, SuperAD provides high-performance server load balancing functions for electric power dispatch business to ensure the stable and efficient operation of electric power dispatch business.
In each provincial grid company, Hongji SuperAD can provide flexible routing for multiple links at the Internet exit and intelligent DNS functions for external network access to ensure that applications can select the optimal path for access; in data service centers, it provides L4-L7 layer application load for the OA system, marketing billing system, email system, and power MIS system of the provincial grid company to ensure the high availability of the business system.
On the State Grid cloud in each provincial grid company, Hongji's virtualized application delivery resource pool solution adopts the deployment mode of Cloud MC+VAD, and flexibly allocates cloud application delivery resources through License distribution management to truly achieve flexible allocation and on-demand expansion, creating an intelligent cloud application delivery management platform for users.
The system adopts multi-core technology, which greatly improves the processing performance of the SuperAD series application delivery devices. At the same time, the product uses a dedicated super parallel processing architecture, which greatly improves the processing performance of L4-L7 and meets users' current and future expansion needs.
The product fully supports virtualization technology, including device virtualization and virtualization operating systems such as Vmware and KVM. Through the pAPI and eRule interfaces provided by the system, it works well with OpenFlow and SDN to smoothly integrate ADC into the SDN network.
The product integrates multiple functions into one: it can achieve local server load balancing, link load balancing, and also implement global load balancing for multiple data centers. For some special and complex functional requirements, the system supports programmable script eRule, which can deeply customize user needs, which is difficult for many load balancing devices to achieve. These functions provide the device with high cost performance.
The system supports a rich load balancing function for L3-L7 application servers. Through deep analysis of application protocols, it can provide comprehensive application load balancing and content exchange capabilities. It also has a comprehensive application health check mechanism to timely diagnose servers or applications that are abnormal. The system has a cluster mode of primary-backup and multi-device groups to ensure the stability and continuity of enterprise applications.
The system can adopt encryption methods such as HTTPS and SSH for network management, avoiding the security risks caused by direct access to devices in plain text communication. The system also incorporates DDoS attack protection functionality. It can provide SSL decryption and encryption, and integrated with CA and client certificates to formulate flexible policies based on certificate identity for access and authorization.
