摘要:
Embodiments of model and system state synchronization are presented herein. An exemplary model of a distributed system includes a plurality of instances where an instance includes an instantiation of a type that includes property values and relationships in the model of the distributed system and includes an associated version history to link each version of an instance to a change request for the distributed system. Other exemplary methods, systems, devices, etc. are also disclosed.

摘要:
In accordance with certain aspects of the model-based policy application, each of a plurality of policies is associated with appropriate parts of a model of a heterogeneous system. A deployment agent is invoked to apply each of the plurality of policies to components associated with the parts of the model. An identification of a change to one of the plurality of policies is received, and the deployment agent is also invoked to apply the changed policy to selected ones of the components associated with the parts of the model.
摘要:
Model-based system monitoring includes identifying multiple monitors configured to monitor multiple components in a system, and accessing multiple health models associated with the multiple monitors. A monitoring policy is generated to monitor the system. The monitoring policy is derived, at least in part, from the multiple health models.
摘要:
Model-based system monitoring includes accessing a model of a system that includes multiple components and executing a monitoring policy to monitor performance of the system. A notification of a problem is received from a first component. A determination is made regarding the cause of the problem. The determination is made, at least in part, based on the model of the system. At least one component associated with the cause of the problem is then identified.
摘要:
In accordance with certain aspects of the design time validation of systems, a description of a system being designed and a description of an environment are received. Both of the received descriptions are used to validate the system against the environment while the system is being designed and prior to attempting to deploy the system.
摘要:
Model-based capacity planning includes accessing a model of a planned system that includes multiple components. Relationships among the multiple components are identified based on the model of the system. Transactions to be performed by the planned system are identified along with a cost associated with each of the identified transactions. Operation of the planned system is simulated using the model of the planned system and the identified costs.
摘要:
Model-based virtual system provisioning includes accessing a model of a workload to be installed on a virtual machine of a system as well as a model of the system. A workload refers to some computing that is to be performed, and includes an application to be executed to perform the computing, and optionally includes the operating system on which the application is to be installed. The workload model identifies a source of the application and operating system of the workload, as well as constraints of the workload, such as resources and/or other capabilities that the virtual machine(s) on which the workload is to be installed must have. An installation specification for the application is also generated, the installation specification being derived at least in part from the model of the workload and the model of the virtual system.
