Claudius is an easy-to-use domain specific language for cloud experiments. It has been designed to speed up process of building distributed experiments and highly reduce time of remote machines configuration. To avoid vendor lock-in, Claudius was build on top of fog.io library, which enables flexible and powerful way to manage machine instances at various cloud providers. Remote commands execution is based on SSH protocol (SSH-2). DLS allow users to generate readable execution graph, which is extremely useful for experiment flow verification and help avoid wasting your money.
