About This Benchmark
Use case perspective
– As an OpenStack Cloud user I want a Ubuntu based VM with MySQL… Why would I choose
docker LXC vs a traditional hypervisor?
OpenStack “Cloudy” perspective
– LXC vs. traditional VM from a Cloudy (OpenStack) perspective
– VM operational times (boot, start, stop, snapshot)
– Compute node resource usage (per VM penalty); density factor
Guest runtime perspective
– CPU, memory, file I/O, MySQL OLTP, etc.
Why KVM?
– Exceptional performance
DISCLAIMERS
The tests herein are semi-active litmus tests – no in depth tuning,
analysis, etc. More active testing is warranted. These results do not
necessary reflect your workload or exact performance nor are they
guaranteed to be statistically sound.
