Many current implementations of manageability were designed for an environment in which services are statically assigned to resources.
As the environment changes to one where resources are dynamically allocated, management must change to address the increased complexity
of the environment.
Ideally, this will be done in a way that reduces visible complexity. Rather than binding a specific service instance to a specific
resource, services should be related to a class of resources. The mapping of a specific instance of a service to a particular server is
best accomplished in the infrastructure.
These are two of the core components required to achieve this vision:
-
A model. This would capture both static and dynamic states of the IT infrastructure, services, and applications, together with
their relationships, resource requirements, and SLOs.
-
Autonomics. This would enable the IT infrastructure to achieve the required SLOs by making policy-based autonomic decisions.
In the remainder of this paper, we focus on these two core components.
