Today, data centers are being built with more entities in a larger
scale in order to satisfy the rapid growth of services and the
demand for efficient service delivery and management. These data
centers are facing scalability, manageability, and consumability
challenges that require breakthrough technology for design and
management. This paper extends previous work that focused on
using virtual appliances for service management, by describing the
following areas: 1) rapid provisioning, which simplifies and
accelerates the deployment and activation of virtual appliances by
checking parameter dependencies and coordinating execution
sequences; 2) selective presentation, which provides flexible
interfaces to present meaningful information through customized
metrics; 3) simplified operation, which enables different operation
granularities by coordinating the operation sequences across virtual
appliances; and 4) automated consolidation, which enables
automated service performance management by automatically
monitoring and optimizing resource allocations. In addition, we
describe the design and prototype of an extendable management
framework, virtualization integrator (VSI), which enables an
appliance builder to easily fulfill the key features of virtual
appliances and coordinate management function across
components located in multiple virtual appliances. By reinventing
virtual appliances with built-in management capability, data center
management is radically simplified and automated. The results,
improved server utilization and simplified system manipulation,
demonstrate the potential for virtual appliances to be fundamental
building blocks for large-scale data centers and potentially for
cloud-based new enterprise data centers.
