Part I:

The rise of containers has led to a broad proliferation of container images. The associated storage performance and capacity requirements place high pressure on the infrastructure of container registries that store and serve images. Exploiting the high file redundancy in real-world container images is a promising approach to drastically reduce the demanding storage requirements of the growing registries. However, existing deduplication techniques significantly degrade the performance of registries because of the high layer restore overhead. In this talk, I will present DupHunter, a new Docker registry architecture, which not only natively deduplicates layers for space savings but also reduces layer restore overhead. I will talk about research challenges faced in designing such a system, and present how the approach compares to the state of the art.


Part II:

In the second part of my talk, I will focus on student interactions. I hope to engage the audience in a discussion about designing scalable high performance computing systems, and research skills that are needed to be a successful independent researcher. Website: https://people.cs.vt.edu/butta/
