Abstract:
In this paper we measured and analyzed the workload on Yahoo! Video,
the 2nd largest U.S. video sharing site, to understand its
nature and the
impact on online video data center design.
We discovered interesting
statistical properties on both static and temporal dimensions of
the workload including file duration and popularity distributions,
arrival rate dynamics and predictability,
and workload stationarity and burstiness.
Complemented with queueing-theoretic techniques, we further
extended our understanding on the measurement data with a virtual
design on the workload and capacity management components of a
data center assuming the same workload as measured, which reveals
key results regarding the impact of
Service Level Agreements (SLAs) and workload scheduling schemes
on the design and operations of such large-scale video
distribution systems.
