Is this the best of all possible clouds?

New Applications Domains:

IoT
Healthcare
Tele-medecine
Network Security
Privileged point of control

New challenges:

High Availability
Strong isolation
Data and Execution state
Enhanced scalability

SLIDE 3

Interoperability User Control Nested Virtualization

From requirements to virtualization design

Legacy support Component-Based Hypervisors Nested Virtualization Minimal TCB Micro-Hypervisors

SLIDE 4

A first Distributed Virtualization Architecture

SLIDE 5

Proof-of-concept and Next Steps

Implementation:

– LL based on Nova hypervisor

Under investigation extensions to support nested virtualization

– UL based on Openstack with multiple virtualization technologies

Evaluating multi-provider architecture
Future work:

– Automated cross-layer/cross-domain security management

VESPA framework for automated security monitoring
User/Provider security policy reconciliation
