Deploying a set of virtual software resource templates to a plurality of nodes is provided. The process identifies a set of virtual machine images and metadata to form a set of virtual software resource templates. The process creates a model that indicates a performance metric based on a number of nodes on which a number of virtual machine images is deployed. The process receives a quality of service requirement. The process determines, using the model, a sufficient number of virtual software resource templates in the set of virtual software resource templates and a sufficient number of nodes in the plurality of nodes to fulfill the quality of service requirement. The process deploys the sufficient number of virtual software resource templates on the sufficient number of nodes using the metadata.

Improved access control techniques for use in a service-oriented computing environment are disclosed. For example, one method for authenticating a client in a service-oriented environment, wherein the service-oriented environment includes a plurality of services, includes the following steps. At least one service of the plurality of services is invoked. State information is associated with the at least one service invoked. The state information is used to authenticate a client with at least one service. Further, a method for access control in a service-oriented environment, wherein the service-oriented environment includes a plurality of services, includes the following steps. A rule specification language is provided. At least one rule is specified using the rule specification language. A verification is performed to determine whether or not the client satisfies the at least one rule. The client is granted access to a service when the client satisfies the at least one rule.

Upgrading a multi-tiered application is provided. In response to receiving a request to upgrade a multi-tiered application, wherein components of the multi-tiered application are deployed across a plurality of virtual machines, an appropriate integrated patch is selected for the upgrade. The selected integrated patch includes an integrated set of patches for the components of the multi-tiered application, state update data, and order constraints. The components of the multi-tiered application specified in the selected integrated patch are upgraded by using the integrated set of patches and order constraints. In addition, the state of the components of the multi-tiered application are updated by using the state update data. Then, the updated state of the multi-tiered application is saved to storage.

摘要:
A computer implemented method, data processing system, and computer usable program code are provided for creating a set of virtual machine image for software. A virtual software resource template is retrieved. Metadata associated with the virtual software resource template is copied and the copy of the metadata is modified to generate personalized metadata for each virtual machine image in the set of virtual machine images. Then, the set of virtual machine images is deployed using the personalized metadata.
摘要:
A computer implemented method, apparatus, and computer usable program product for managing a distributed software application. The process identifies metadata describing a set of dependencies of a set of software components in the distributed software application from data associated with the set of software components. The process then identifies a sequence for changing an operational state of the set of software components of the distributed software application from the metadata to form an identified sequence. Thereafter, the process changes the operational state of the set of software components using the identified sequence.
