vbench: a Benchmark for Video Transcoding in the Cloud


vbench is the first benchmark for the emerging video-as-a-service workload and will be presented at ASPLOS 2018 [1].

Current estimates place video at 71% of evening traffic in North America and project that this number will grow to 80% by 2020. Each video that is streamed over the internet has been transcoded at least once by a cloud video provider such as YouTube or Facebook. This creates a great computational burden on the infrastructure of these companies. Furthermore, the rate of growth of uploaded video content has now surpassed the rate of growth of computational power for standard CMP systems. New solutions are necessary in this space.

vbench captures the nuances of this important workload including the tradeoffs that cloud video providers have to navigate between Quality of Experience (QoE), network cost, compute cost, and storage cost.


vbench is based on open source software and freely redistributable video sequences.
