摘要:
Computerized methods, systems, and computer-readable media for promoting cooperation between a first and second virtual network overlay (“overlay”) are provided. The first overlay is governed by a first authority domain and includes members assigned virtual IP addresses from a first address range. The second overlay is governed by a second authority domain, which is associated with a second federation mechanism, for negotiating on behalf of the second overlay. The second federation mechanism is capable of negotiating with, or soliciting delegation of authority from, a first federation mechanism that is associated with the first authority domain. When negotiations are successful or authority is delegated, the second federation mechanism establishes a communication link between the second overlay and the first overlay or joins a member of the second overlay to the first overlay. Joining involves allocating a guest IP address from the first address range to the member.

摘要:
A design tool includes a service definition model to enable abstract description of distributed computing systems and distributed applications. The design tool also includes a schema to dictate how functional operations within the service definition model are to be specified. The functional operations include design of distributed applications, deployment of distributed applications, and management of distributed applications.
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:
The present invention relates to a system and methodology for resource query management. The system includes a resource manager, a query engine and a filter component. The system facilitates construction and management of a resource query across resource type(s) that may be similar, different, incongruent and/or distinct. Accordingly, an SQL environment is leveraged to perform efficient, complex and intensive queries and/or operations using resource query constraint(s) from a resource constraint(s) store and the filter component over large set(s) of resources from the resource pool.
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.
