SAMC, Cloud Bug Study (CBS)


Cloud computing era is here. As more and more computing tasks depend on cloud computing, the availability, reliability, and efficiency of cloud services are becoming more and more important. Unfortunately, major dependability problems still take place even recently. Some cloud infrastructures experienced major outages. Some customer data were permanently lost. To sum up, it seems that the computing forecast for tomorrow is "cloudy with a chance of failure."

In UCARE lab (UChicago systems research on Availability, Reliability and Efficiency), we are improving the dependability of storage and cloud computing systems in the context of (1) performance stability, specifically about managing "limpware", (2) reliability, specifically about combating distributed concurrency bugs, and (3) scalability, specifically about finding latent scalability bugs.
