Virtualization technologies constitute a key enabling factor for
flexible resource
management in modern data centers, and particularly in cloud environments.
Cloud providers need to dynamically manage complex infrastructures in a
seamless fashion for varying workloads and hosted applications, independently of
the customers deploying software or users submitting highly dynamic and
heterogeneous workloads. Thanks to virtualization, we have the ability to manage
vast computing and networking resources dynamically and close to the marginal
cost of providing the services, which is unprecedented in the history
of scientific
and commercial computing.

Various virtualization technologies contribute to the overall picture
in different
ways: machine virtualization, with its capability to enable
consolidation of multiple
under-utilized servers with heterogeneous software and operating systems (OSes),
and its capability to live-migrate a fully operating virtual machine
(VM) with a very
short downtime, enables novel and dynamic ways to manage physical servers;
OS-level virtualization, with its capability to isolate multiple user-space
environments and to allow for their co-existence within the same OS kernel,
promises to provide many of the advantages of machine virtualization with high
levels of responsiveness and performance; I/O Virtualization allows physical
NICs/HBAs to take traffic from multiple VMs; network virtualization, with its
capability to create logical network overlays that are independent of the
underlying physical topology and IP addressing, provides the fundamental
ground on top of which evolved network services can be realized with an
unprecedented level of dynamicity and flexibility; the increasingly adopted
paradigm of Software-Defined Networking (SDN) promises to extend this
flexibility to the control and data planes of network paths.  These technologies
have to be inter-mixed and integrated in an intelligent way, to support
workloads that are increasingly demanding in terms of absolute performance,
responsiveness and interactivity, and have to respect well-specified Service-
Level Agreements (SLAs), as needed for industrial-grade provided services.
Indeed, among emerging and increasingly interesting application domains
for virtualization, we can find big-data application workloads in cloud
infrastructures, interactive and real-time multimedia services in the cloud,
including real-time big-data streaming platforms such as used in real-time
analytics supporting nowadays a plethora of application domains. Distributed
cloud infrastructures promise to offer unprecedented responsiveness levels for
hosted applications, but that is only possible if the underlying virtualization
technologies can overcome most of the latency impairments typical of current
virtualized infrastructures (e.g., far worse tail-latency). What is
more, in data
communications Network Function Virtualization (NFV) is becoming a key
technology enabling a shift from supplying hardware-based network functions,
to providing them in a software-based and elastic way. In conjunction with
(public and private) cloud technologies, NFV may be used for constructing the
foundation for cost-effective network functions that can easily and seamlessly
adapt to demand, still keeping their major carrier-grade
characteristics in terms
of QoS and reliability.

The Workshop on Virtualization in High-Performance Cloud Computing (VHPC)
aims to bring together researchers and industrial practitioners facing
the challenges
posed by virtualization in order to foster discussion, collaboration,
mutual exchange
of knowledge and experience, enabling research to ultimately provide novel
solutions for virtualized computing systems of tomorrow.

The workshop will be one day in length, composed of 20 min paper presentations,
each followed by 10 min discussion sections, and lightning talks, limited to 5
minutes. Presentations may be accompanied by interactive demonstrations.
