Allocating nodes in a service definition graph to resources in a resource catalogue according to node specific rules

摘要

A server 205, 206 makes a request for a service in a distributed computing system 200, such as a cloud computing environment. A management engine system, running a management engine 209, 201, analyses a model 211 of the requested service. The service model contains a graph of nodes. Each node has a resource type and may have management rules. For each node, the management engine system uses a resource instance catalogue 250 and a service provider catalogue 210 to find a resource manager 214, 219, 222, which can provide a resource instance, which matches the type and rules of then of the node. The resource manager then creates the resource instance and allocates it to providing the requested service. The rules may include load requirements for resource instances, which may be updated based on the actual monitored loads of the instances.
