In the field of industrial automation, the stability and reliability of systems are crucial. Today, I would like to share an advanced topic – PLC fault injection techniques. This technology helps us identify potential issues early in the system development phase, thereby improving system robustness. What is Fault Injection? Fault injection is essentially the intentional … 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
1. Let’s clarify what Chaos Engineering is. A few days ago, my colleague Wang was mumbling in the break room: “Our system claims to be highly available, but who knows if it can really hold up when something goes wrong?” This hits the nail on the head—Chaos Engineering is essentially the study of proactively finding … Read more
