Query: Towards Self-Improving Hybrid Elasticity Control of Cloud-based Software
  Systems   Elasticity is a form of self-adaptivity in cloud-based software systems that
is typically restricted to the infrastructure layer and realized through
auto-scaling. However, both reactive and proactive forms of infrastructure
auto-scaling have limitations, when used separately as well as together. To
address these limitations, we propose an approach for self-improving hybrid
elasticity control that combines (a) infrastructure and software elasticity,
and (b) proactive, reactive and responsive decision-making. At the
infrastructure layer, resources are provisioned proactively based on
one-step-ahead workload forecasts, and reactively, based on observed workload
variations. At the software layer, features are activated or deactivated in
response to transient, minor deviations from the predicted workload. The
proposed approach can lead to better performance-aware and cost-effective
resource management in cloud-based software systems. We validate our approach
via a partial realization and simulation with real-world datasets.
