SCOPE:

Cloud computing offers a computational model where network, storage, and compute domains can be abstracted into virtual resources offered on demand. While these abstractions offer opportunities to significantly simplify the management and optimize the use of resources, they impose additional
challenges on assuring the quality of service (QoS).

In the context of multi-tenancy, the same physical resources are shared by different users that do not necessarily share the same service level agreements; hence the QoS distinction has to be enforced at a finer grain. Moreover, certain attributes of the QoS may contradict with others, for instance, high availability favors replication and distributed redundancy while energy efficiency favors de-duplication and consolidation. The multi-layered architecture of the distributed cloud requires not only a thorough orchestration between layers to ensure the required QoS, but also makes the root cause analysis even more complicated in case of the SLA violation. Continuous changes and migrations of the resources allocated at all layers of abstraction pose further challenges to detecting problems, identifying their location and reasoning about causality.

The aim of this workshop is to raise awareness of the challenges of the QoS assurance in the cloud, and bring together practitioners and researchers to discuss potential solutions.

TOPICS:

The workshop solicits high-quality papers authored by both industry and academic contributors that address
(but not limited to) the following topics:

- Security assurance, and regulations compliance in the Cloud
- Multi-level isolation orchestration for the Cloud tenants
- High Availability and fault tolerance approaches and techniques in the Cloud
- Dynamic performance assessment and prediction
- Telemetry and smart metering in the Cloud
- Managing Carbon Footprint versus QoS trade-offs
- Requirement modeling and specification for the QoS
- Orchestration and refinement for cloud QoS policies
- Dynamic verification and validation of cloud service quality
- Automated generation of multi-layer QoS test cases
- Autonomic approaches for assurance of cloud service quality
- Real-time analytics integration with QoS control loops
- Evaluations of cloud QoS impact on application or service QoE
- Automatic generation of workflows related to assuring QoS in cloud
- Machine learning and data mining techniques for optimizing QoS assurance processes
- The effect of virtualization (VMs vs. Containers, NFV vs. specialized HW) on QoS
