Experimental reproducibility is of primordial importance in several fields of research, including computer science. Despite so, it is far from trivial to reliably build software systems that can be tested under challenging environments. Consider a large-scale distributed system (e.g., a key-value store) over a public cloud infrastructure such as Amazon AWS. Its performance (e.g., latency, throughput) vary greatly through time, in unexpected (and sometimes hard to anticipate) manners. System deployers only found out about the unexpected behaviours once the systems are up & running, when perhaps they have to face unexpected service interruptions. This is particularly dauting when measurements done on one day differ greatly from the same ones executed, for instance, after some time by different team of researchers in (apparently) similar conditions. While emulators or software simulations provide partial insights, they clearly lack the benefits of real-life deployments.

This 1-day workshop will address practical aspects of evaluating the reliability and dependability of software systems, covering different facets of experimental reproducibility.

Students will be exposed to tools and best-practices to evaluate real-world systems built on top of de-facto standard echnologies (such as Docker and Google Kubernetes).

It's worth mentining how several major CS conferences have started implementing research reproducibility efforts (check out for examples SOSP'19, PLDI'19) and ongoing efforts are in place since years. 


 The program, as well as the schedule of the talks, can be subject to last-minute changes.
