Traditional testing methodologies and tools are inadequate for finding and fixing the new class of failures that result from microservices interacting with each other in complex ways while running on top of intricate infrastructures. One real-world example is a site-wide failure in www.amazon.com that started with a single server failing to retrieve product information from a catalog. Due to mishandling of the error, the server started returning empty responses. Because it was not actually accessing the catalog, it was returning these empty responses much faster than usual. This caused the loa ..read more

Modern applications are built on a microservices architecture that leverages cloud-native technologies. This architecture has many benefits regarding scalability and fault-tolerance of individual components, but it also increases the complexity of the applications, mostly due to the interdependencies between services. This complexity makes it difficult for engineers to fully understand how their applications will react to abnormal conditions, such as a dependency failure or performance degradation. Under these conditions, applications frequently fail in unpredictable ways. According to a study ..read more
