As a unicorn in the education industry, facing ToB customers and many ToC end users in different regions of the country and the world, how to ensure the terminal experience and platform availability becomes the key. During the service process, the Weidong cloud service team encountered the following problems.

problem found

In the process of building an educational informatization platform for a certain place, abnormal access of local users often occurs. In order to solve this problem, the Weidong cloud service team checks the website performance and each link of the network link one by one. After confirming that there is no problem with the platform availability, the Weidong cloud service team will focus on the network environment.

Although the above problem was finally solved with the operator, the root cause of the abnormality was the limitation of the local network environment, which caused abnormal user access. However, the Weidong cloud service team checked normally during the remote test, which made it impossible to locate the problem location more quickly, making the fault recovery time longer. Faced with such a problem, how to ensure the availability of users in different regions of the country and even the world, fully grasp the local real network environment and various indicators of website performance, and compress the failure recovery time as much as possible, has become an important pain point for the Weidong cloud education service team.

In the process of serving a customer in a certain place in the southwest, the Weidong cloud service team received a report from a user in a certain region, and would jump to an illegal gambling platform when browsing the platform website, which would cause the risk of loss of user assets. The Weidong cloud service team was also unable to reproduce the related problems during remote testing and related testing through VPN proxy.

With the in-depth troubleshooting, when conducting research and interviews on users who reported abnormality, the Weidong cloud service team found that the users who reported abnormality all used the broadband of a small local network operator. After testing, it was found that the hijacking was indeed caused by the operator.

solution

Although there are various monitoring methods, how to monitor more comprehensively to check for leaks and make up. How to ensure the stability and security of daily services has become an important topic of the Weidong cloud service team. After understanding the above problems, Alibaba Cloud communicated with the Weidong cloud service team and agreed that it is the best product with global mass monitoring nodes and non-intrusive "cloud dialing and testing" to solve the problem.

Active monitoring of city availability in key cities:

By configuring network monitoring tasks, select IDC monitoring points in major key cities, monitor the network connectivity of key pages of the target website, and configure a faster monitoring frequency. Once availability problems occur, alarms will be notified in time. The IDC monitoring point is more stable than the LastMile monitoring point, which can reduce the probability of false positives.

page access performance analysis:

The speed of opening web pages is also a key issue that Weidong Cloud Education needs to focus on. For their customers, the speed of web pages directly affects the quality of their customers' online education. For the web page opening speed, Weidong Cloud selected the LastMile monitoring points in all major provinces and cities, and configured browsing tasks to analyze the performance of the website homepage and key pages, focusing on network connection delay, the total number of page request elements and CDN analysis. For quality, after locating the root cause of the problem, relevant suppliers or internal R&D teams will be pushed to optimize.

final effect

With the help of cloud dialing test, Weidong cloud education service team further improves the monitoring system. Use the lowest cost to fully grasp the actual access experience of end users in different regions of the country and even the world. The fault recovery time is shortened by more than 20%, and the fault response efficiency and user satisfaction are greatly improved.
