I& #39;ve realized that cat photos are more popular than posts about my research, so let& #39;s try to combine the two:
our upcoming OSDI paper, Pegasus, explained through photos of our cats

Skewed workloads are a challenge for storage systems. Some cat bowls are more popular than others.
Provisioning for the peak workload means that some servers have to run at low utilization
If we route the cats via a programmable switch instead, using it as a directory...
...we can forward each cat to the least loaded replica...
...and achieve close-to-uniform load balancing even though the workload is f̶l̶u̶f̶f̶y̶-̶ heavy-tailed
