Industry Solutions
The education industry is facing a growing user and data load with the rapid development of digitization and online education. Therefore, load balancing has become crucial. With the rise of online education, the number of users in educational institutions has increased dramatically. Students, teachers, and administrators need to access various online educational resources, including course content, video lectures, online tests, etc. This will lead to a significant increase in server and network load. The education industry often faces peak periods of data such as course registration deadlines or exam periods during which server load can greatly increase. Without an appropriate load balancing mechanism, this can lead to system collapse or severe response time delays. Online education platforms provide multiple content and services such as videos, documents, real-time interactions, discussion forums, etc. Different types of content and services may require different server resources and load balancing strategies to ensure efficient operation.
In summary, the education industry faces complex load balancing challenges in its digital transformation to ensure users can receive high-performance, high availability, and secure online educational experiences. Effective load balancing strategies and technologies will be key factors in achieving this goal.
Educational platforms typically face a large number of users accessing simultaneously at specific time points such as registering for courses, taking online tests, or submitting assignments. Therefore, a load balancing mechanism is required to distribute these high concurrent visits to ensure system stability and performance. Online education platforms provide multiple types of content and services such as videos, documents, real-time interactions, etc. Different types of content may require different types of server resources and load balancing strategies to ensure optimal user experience. Backend application systems also need to be able to automatically adjust resource allocation based on actual needs during high concurrent traffic periods. During peak periods, systems can dynamically add servers, while during low periods they can automatically reduce resources to reduce costs.
In summary, the education industry requires a robust and flexible load balancing solution to meet multiple demands such as high concurrent access, diverse content types, elastic expansion, monitoring, and high availability. This will help ensure that educational platforms provide stable, high-performance, and secure online educational services.
As a manufacturer specializing in intelligent application delivery, Hongji Technology has been helping users in various industries solve network application availability and performance issues as well as security issues. In response to users' concerns, we have proposed our own solution to help users optimize and improve the availability of their business systems.
Given the location of the network architecture and its scalability for the future, we recommend using two SuperAD devices to provide load balancing for multiple exit links. The solution design fully considers the scalability of future data centers. Hongji SuperAD devices achieve load balancing for both links and include three major functions: link load balancing, global load balancing, and server load balancing. This provides excellent scalability for subsequent network and application system expansions as well as stability and optimization construction.
For internal networks providing services to external users, Hongji SuperAD devices use intelligent DNS technology to bind multiple operator public network addresses to one domain name. Hongji SuperAD devices use different load balancing strategies to return the best access address for different operator users based on specific policies and achieve load balancing for user inbound traffic while ensuring high availability of each service platform.
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.
