Fault Injection: An Effective Method for Testing Observability Maturity

As technologies like cloud-native and microservices bring competitiveness to enterprises, they also make systems more complex. Increasingly complex systems make it difficult to identify the root causes of failures, leading to most of the time spent on locating issues. Being able to clearly understand what is happening in the system is one of the prerequisites … Read more

Xiaomi’s Practice of Fault Injection Platform Based on Chaosblade

Xiaomi's Practice of Fault Injection Platform Based on Chaosblade

Source: Xiaomi Technology Author: Li Qianming – Big Data SRE Currently, domestic practices are more inclined towards fault testing, which involves conducting fault injection experiments in specific scenarios and verifying whether expectations are met. This type of testing has relatively controllable risks, but the downside is that it does not explore more scenarios through fault … Read more

Exploring Fault Injection in Chaos Engineering

Exploring Fault Injection in Chaos Engineering

Authors | Ye Fei, Qiong Gu Introduction: Do you think chaos engineering is far from you? But the moment a failure occurs is not chosen by you, but rather that moment chooses you. All you can do is prepare for it. Chaos engineering has been applied internally at Alibaba for many years, and the open-source … Read more

Laser Fault Injection Microsystem for IC Chip Testing

Laser Fault Injection Microsystem for IC Chip Testing

Integrated circuits in aerospace applications are affected by the space radiation environment, facing the risk of failure. One of the main faults occurs when a single high-energy particle passes through sensitive nodes in the chip, generating ionized charge, leading to data flips, functional failures, current surges, or even destruction of the chip. The fault injection … Read more
