Research Projects

Cloud Native Storage
Modern cloud computing is undergoing a transformation, driven by containerization technologies such as Docker and Kubernetes and the rising popularity of microservice based architectures. The result is that cloud workloads are now more diverse and cloud applications are more elastic and more dynamic. Storage operations that were previously infrequent like volume creation and deletion are now executed dozens or hundreds of times every day.

Understanding the performance of an application or storage system in this environment is difficult because there are no tools that can recreate all of these new cloud native conditions. To address this problem, we are designing and building a benchmark capable of generating workloads that are representative of modern, cloud native environments. This benchmark will include measurement and analysis components to help debug performance problems, and it will be used to evaluate and study storage performance in cloud native environments.
