Since 2021, he has been responsible for promoting and implementing chaos engineering at Qunar, focusing on quality gap detection and construction based on chaos engineering. 1. Introduction Qunar’s chaos engineering relies on ChaosBlade … Read more
In recent years, with the popularization of new technologies such as distributed system architecture, microservices concepts, and PaaS service components in the financial industry, traditional monolithic business system architectures based on mainframes and storage are rapidly evolving towards distributed system architectures based on cloud foundations (referred to as new system architecture). The new system architecture … Read more

In fault testing, the HTTP protocol is an extremely common and important testing target. Whether it is inter-service communication in a microservices architecture or external API calls, HTTP plays a critical role in data exchange. When issues such as slow responses, abnormal connections, or request failures occur, anomalies at the HTTP layer are often the … Read more
1. Introduction: Why is Chaos Engineering Needed? In the cloud-native era, system complexity is growing exponentially, and traditional testing methods can no longer cover all failure scenarios. Chaos Engineering is a proactive experimental approach that injects faults to help us discover system weaknesses before real failures occur in production environments. As a CNCF incubated project, … Read more
1. Introduction In database clusters, network isolation is one of the common fault scenarios. For example, when a node cannot communicate with other nodes due to a network interruption, the cluster may trigger a master-slave switch, data synchronization interruption, or split-brain issues. By actively injecting network isolation faults, we can verify the cluster’s high availability, … Read more
Click the “blue text” above to follow us Server down! Database unreachable! Network timeout! — Do these words make your scalp tingle? In a production environment, systems can face various bizarre failures at any time. But how do we know if the system can withstand these “critical hits”? Waiting until something goes wrong to regret? … Read more
Click the “blue text” above to follow us Late-night overtime, just about to leave, suddenly the production environment alarms go off! Checking logs, monitoring, troubleshooting… After two hours of hassle, I found out it was a cascading failure caused by a timeout in a dependent service. Sigh! Does this situation sound familiar? In a microservices … Read more
▌Introduction: A New Tool for Chaos Engineering ChaosBlade, as an open-source chaos engineering toolchain from Alibaba, abstracts chaos experiments into Kubernetes CRD resources through the ChaosBlade-Operator project. Utilizing the open capabilities of K8S, CRD resources can manage all software and hardware resources and interact with various resources, achieving declarative chaos experiment management that makes fault … Read more
In the context of continuous innovation and development in financial digitization, Fudian Bank’s information system has gradually transitioned from the original monolithic centralized architecture to a distributed architecture, and from the original IOE architecture to a fully domestically produced architecture. In 2024, Fudian Bank will take the lead in launching the cloud migration of the … Read more
