Each of a plurality of nodes in an overlay network includes information for a corresponding resource-on-demand system, wherein the information may be used to select a resource-on-demand system to host the workload. A request to place a workload is received at a node in an overlay network. A distributed control algorithm is executed for selecting a resource-on-demand system host the workload.

A control system for controlling the allocation of computer resources includes control plug-ins arranged in a multi-level hierarchy. A first-level control plug-in is operable to generate instructions for a resource manager to allocate computer resources for an application. A second-level control plug-in is operable to generate instructions for the first-level control plug-in to control the allocation of the computer resources for the application.
摘要:
A method of automated deployment managed by a service provider, of a computer based business process, involves generating a model (730) of the business process including a design of computing infrastructure, and deploying the model on hardware (770) dedicated to the enterprise, with an interface for the service provider to enable ongoing management of the deployed process by the service provider. Having dedicated hardware means the location of the hardware can be arranged to suit the enterprise. This means limitations such as bandwidth or latency of WAN links, can be addressed by choosing the location of the dedicated hardware appropriately. Trust of security can also be increased compared to that of the shared data centres. The automated model driven deployment can help enable the service provider to provide such deployments on different types of hardware. The need for the enterprise to maintain specialist expertise in house is reduced.
摘要:
A method of determining a placement of services of a distributed application onto nodes of a distributed resource infrastructure. In an embodiment of the present invention, a placement indicator for a specific service is provided. Communication constraints between node pairs are also provided. The communication constraints ensure that a sum of transport demands between a particular node pair does not exceed a transport capacity between the particular node pair. Constraints can be expressed for preventing unwanted placements. Preferences can be expressed for preferring specified placements. Each term of the sum of transport demands comprises a product of a first placement variable, a second placement variable, and the transport demand between the services associated with the first and second placement variables. The placement indicator, the communication constraints, and an objective comprise an integer program. A local search solution is applied to solve the integer program, which determines the placement of the services onto the nodes.
摘要:
A system and method for managing a plurality of agents in a plurality networked computing hosts. In various embodiments, a repository is provided with references to installation code for installing the agents. Boot stubs are executable on the hosts. The boot stubs retrieve references to the installation code and load the installation code on the hosts. A directory contains topology data that indicate the hosts on which boot stubs and agents are installed, and an initiator retrieves the topology data and initiate execution of the boot stubs.
摘要:
Method and apparatus for optimizing allocation of computer resources between server and service models. A server model is established in response to user input data. The server model includes one or more server nodes, and each server node has an associated set of capacity attributes. In addition, a service model is established that includes one or more service nodes. Each service node has an associated set of demand attributes. In response to a user selection, one of a plurality of optimization methods and one of a plurality of optimization policies, as embodied in objective functions, are selected for mapping the server nodes and service nodes. An optimized mapping is then generated of the server nodes in the server model to the service nodes in the service model using the selected optimization method, along with the demand and capacity attributes.
摘要:
Method and framework for identifying optimal allocations of computing resources in a complex, distributed data processing environment. A plurality of server models are established, with each server model including one or more server nodes and each server node having an associated set of capacity attributes. Similarly, a plurality of service models are established, each service model including one or more service nodes and each service node having an associated set of demand attributes. The server models are defined with a layered relationship as are the service models. A node that is part of a model in one layer corresponds to a model in the next-lower layer. The invention generates optimized mappings of service nodes that are described in user-selected service models to server nodes that are described in user-selected server models, as a function of the associated sets of demand and capacity attributes.
