The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that dynamically manage exchanges of data using a cryptographically secure distributed ledger and homomorphic commitments. For example, and in response to an occurrence of a triggering event, an apparatus may obtain parameter values that characterize the data exchange, first commitment values representative of the parameter values, and a first digital signature. In response to a verification of the first digital signature, the apparatus may apply a second digital signature to commitment data that includes the first commitment values and a second commitment value representative of the first digital signature. The apparatus may transmit a signal that includes the commitment data and the second digital signature to a computing system, which generates an element of distributed ledger that includes the commitment data and the second digital signature in response to a verification of the second digital signature.

Dynamically managing exchanges of data using a distributed ledger and homomorphic commitments

The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that dynamically generate and manage a distribution of asymmetric cryptographic keys using distributed ledgers. For example, an apparatus may extract, from a hierarchical data structure, an index value associated with a corresponding element of permissioning data. The apparatus may also extract, from a first element of a distributed ledger, cryptographic data that includes a first public cryptographic key associated with the hierarchical data structure. The apparatus may generate a second public cryptographic key based on the first public cryptographic key and the extracted index value, and encrypt information using the second public cryptographic key. The encrypted information may be associated with the corresponding element of permissioning data, and the second public cryptographic key may be discarded in response to the encryption of the information.

Dynamic generation and management of asymmetric cryptographic keys using distributed ledgers

A service cost model for services offered in a cloud-computing environment is generated by discovering cost-related attributes in a service catalog of provisioned virtual machines and applications provisioned thereon. The set of cost-related attributes includes at least one of the following: outage frequency, time to repair, cost of repair information, and time claimed by each resource type to fix past outages. The generated service cost model is tracked and adjusted against actuals periodically to reflect the true cost of offered services. Further by federating with other cloud service providers, the costs of a same service are compared between the different providers, and accordingly a recommendation for a provider based on the costs is proposed.

Generating a service cost model using discovered attributes of provisioned virtual machines

According to embodiments of the present invention, one or more computer processors determine a source for a performance indicator of a target service element is known. The one or more computer processors select, at run time, a source for the performance indicator that has a least amount of information gaps. The one or more computer processors determine information associated with the performance indicator from the source. The one or more computer processors determine whether the determined information associated with the performance indicator is more current than a quality indicator periodicity value that is associated with the target service element. In response to determining that the determined information associated with the performance indicator is more current than a quality indicator periodicity value that is associated with the target service element, the one or more computer processors selecting the performance indicator.

Increasing the accuracy of service quality management metrics

A tool for a computing service using a computing usage policy. The tool receives by one or more computer processors, a configured usage policy. The tool validates, by one or more computer processors, the configured usage policy. The tool determines, by one or more computer processors, one or more rules governing the configured usage policy. The tool executes, by one or more computer processors, the one or more rules governing the configured usage policy. The tool manages, by one or more computer processors, one or more cloud service resources according to the configured usage policy.

Usage policy for resource management

Automatically generating visualization artifacts corresponding to related service operation interfaces is provided. A user level visualization finite state machine instance is created for a specific service instance based on user activation and deactivation of service operations in the specific service instance and user selection of a start visualization state. The service operations are included in a service level visualization finite state machine instance for the specific service instance. Visualization artifacts are automatically generated based on the user level visualization finite state machine instance and parameterized entities bound to a concrete visualization component. The visualization artifacts are outputted in a service operation interface of the specific service instance for a user to visualize and interact with, resulting in the elimination of individual user unwanted server side function in the units of service operations without server side processing.

Automatic personalization of user visualization and interaction in a service-oriented architecture interface

A method for modeling, validating, and monitoring a service level agreement (SLA) associated with a business process is disclosed herein. Such a method may include providing a library of reusable SLA component types. Functionality may be provided to enable a user to create SLA components from the reusable SLA component types. Functionality may also be provided to enable the user to assemble the SLA components into an SLA model having a hierarchy. In the SLA model, events may be passed between the SLA components to trigger behavior by the SLA components. SLA components at the lowest levels of the hierarchy may be configured to receive events from the business process. The method may further validate the SLA model against the business process to ensure the business process can generate the events required by the SLA components. A corresponding apparatus and computer program product are also disclosed herein.

Flexible SLA modelling and validation

Embodiments of the invention provide for an integrated entity of a personalized data resource across the WWW with integrated operations. Such embodiments can reside on premises (or service side) as an integrated personalized data resource which is constructed from each of a number of web applications over the Internet that fetch and provide a piece of user information.
