Surprising pattern of failure in IaaS Using the package shared by researchers, but running on Openstack 11

Surprising pattern of failure in IaaS Time to failure (h) 12

The ecosystem of things that can affect performance “ NULL ” 13

In summary… Lots of choices! Lots of opportunity to fail/succeed We need help from other communities Is software defined networking (SDN) really the panacea to latency? 14
