DECAF - An Exploratory Study of Distributed Cloud Application Failures
Description
The DECAF project (An Exploratory Study of Distributed Cloud Application Failures) contributed to improving the understanding of the failure modes of cloud applications. To this end, fault injection targeting virtualised systems was the main experimental approach. The project also addressed the problem of guaranteeing availability and reliability. To achieve this, architecture-based reliability prediction, distributed redundancy management, and failure prediction algorithms were examined as means to improve dependability. In addition to the scientific results, the project had as outcome a fault injection tool that is able to emulate errors within virtual machines and the hypervisor (demonstration videos available through https://youtu.be/6KOhGLsbMOk and https://youtu.be/g8iP7Bx68nE).
