Abstract
Management and automation are important issues in enterprise environments,
often consuming the largest fraction of the overall IT
budget. A key challenge here is co-ordination across multiple management
solutions deployed in different management domains, including
across hardware and software, across different levels of abstraction,
and across different hosts. This paper makes three contributions
to addressing this problem. First, we propose a novel management
co-ordination architecture for virtualized environments.
Our architecture includes two powerful abstractions – m-channels,
which provide mechanisms for communication between the hardware,
virtual machines, and applications and m-brokers, which allow
high-level policy co-ordination across different management
agents. Second, we discuss Dom-M, an instantiation of our architecture
in the context of the Xen hypervisor, and identify tradeoffs
between different implementations of such management domains.
Finally, to demonstrate the effectiveness of our approach, we implement
and evaluate different cross-level solutions for power management
using our abstractions, and also discuss qualitatively other
applications including storage backup, inventory management, and
trust management.
