While co-locating virtual machines improves utilization in
resource shared environments, the resulting performance interference
between VMs is difficult to model or predict. QoS
sensitive applications can suffer from resource co-location
with other less short-term resource sensitive or batch applications.
The common practice of overprovisioning resources
helps to avoid performance interference and guarantee QoS
but leads to low machine utilization. Recent work that relies
on static approaches suffer from practical limitations due to
assumptions such as a priori knowledge of application behaviour
and workload.
To address these limitations, we present Stay-Away, a
generic and adaptive mechanism to mitigate the detrimental
effects of performance interference on sensitive applications
when co-located with batch applications. Our mechanism
complements the allocation decisions of resource schedulers
by continuously learning the favourable and unfavourable
states of co-execution and mapping them to a state-space
representation. Trajectories in this representation are used
to predict and prevent any transition towards interference of
sensitive applications by proactively throttling the execution
of batch applications. The representation also doubles as a
template to prevent violations in the future execution of the
repeatable sensitive application when co-located with other
batch applications. Experimental results with realistic applications
show that it is possible to guarantee a high level of
QoS for latency sensitive applications while also improving
machine utilization.Peer ReviewedPostprint (published version)
