  • Patent number: 11226829
    Abstract: A system is reconfigured at runtime when triggers are issued in response to events taking place in the system. The triggers, which are issued on configuration entities, are correlated by transferring relations of the configuration entities to relations of the triggers to thereby identify related triggers. Elasticity rules are selected for the triggers, where the elasticity rules specify actions for resource allocation or deallocation at runtime. Selected actions of the selected elasticity rules for the related triggers are executed to reconfigure the system according to a set of action correlation meta-rules which provide an ordering of the actions.

  • Publication number: 20210294729
    Abstract: A system configuration is validated in a production environment using test cases selected from a test suite, which has validated a first configuration of the system in a development environment. In response to a change in environments, a reduced set of requirements is formed by removing one or more requirements from a set of requirements against which the first configuration is validated. The removed requirements include environment agnostic requirements. The removing is based on at least a classification of configuration parameters, and a first relation between the requirements and the configuration parameters. A reduced test suite is formed by selecting, from the test suite, the test cases that test the system against the reduced set of requirements. The reduced test suite is applied to a second configuration of the system to validate that the system operates in compliance with the set of requirements in the production environment.

  • Patent number: 11099860
    Abstract: A system performs runtime adjustment of a configuration model. The system receives, at runtime, a change request directed at one or more modified entities in the configuration model. Based on leadership information, one or more infringing entities are identified among the one or more modified entities. The leadership information indicates an impact that one entity has on another entity with respect to a given constraint. Based on the leadership information, a propagation scope is identified for a constraint violated by an infringing entity. The propagation scope includes the infringing entity and other entities that are potentially affected by the request. For resolving single constraint violation, a collection of paths are created in the propagation scope and a path is selected one at a time starting from the shortest path in the collection. For resolving multiple constraint violation, a bonded path is formed for a group of propagation scopes that overlap.

  • Publication number: 20210165694
    Abstract: Resources in an Infrastructure-as-a-Service (IaaS) system are upgraded in an iterative process. In response to an upgrade request indicating requested changes to a current configuration of the system, one or more graph representations of the current configuration and the requested changes are created. The graph representations include a control graph which has vertices representing resource groups, and edges representing dependences among the resource groups. A batch of resource groups is identified to be upgraded in a current iteration based on the dependencies and Service Level Agreement (SLA) requirements including availability and elasticity of the system. Upgrade operations are executed on the identified batch using selected upgrade methods which handle potential incompatibilties during transition of system configurations. The graph representations are updated to include any new requested changes and recovery operations in response to feedback of failed upgrade operations.

  • Publication number: 20200366743
    Abstract: Automation of the design and management of network services is achieved by automating the enactment of a process model. The process model models activities and ordering among actions in a process for the network services. Each activity includes a set of actions and each action is associated with a model-based transformation which transforms one or more input models into one or more output models. A megamodel is constructed. The megamodel incorporates the process model and describes relations among resources to be used by model-based transformations of the process model. The resources include models and meta-models. Based on the megamodel, a transformation chain is generated. The transformation chain contains coordinated sequences of the model-based transformations. The transformation chain is enacted to thereby enact the process model for the network services.

  • Patent number: 10768945
    Abstract: A system configuration is generated by integrating source models. Transformations are generated according to a weaving model that specifies relations among metamodels of the source models and the system configuration. The transformations, when executed, transform the source models into the system configuration that includes target entities. From the transformations, one or more integration constraints are generated for each target entity to be created or modified by an operation of the transformations. The integration constraints describe semantics of the relations specified by the weaving model. System configuration constraints are formed to include the integration constraints in addition to constraints of each source model. The transformations are executed to transform the source models into the system configuration to generate the system configuration obeying the system configuration constraints.

  • Patent number: 10754694
    Abstract: A system is upgraded by rolling upgrade with dynamic batch sizes in multiple iterations. The system includes multiple hosts that host multiple resources. The rolling upgrade calculates a number of hosts to upgrade and a number of resources to upgrade for each iteration. The calculation subtracts a reserved number of hosts from a capacity of the system to account for potential failover and potential resource scaling operations during the iteration. Based on the calculated number of hosts to upgrade, it is determined whether the system has a capacity for upgrade. If the capacity exists, the calculated number of hosts to upgrade and the calculated number of resources to upgrade are upgraded, while accepting resource scaling requests during the iteration.

  • Patent number: 10698801
    Abstract: An upgrade campaign specification upgrades a system from a current configuration to a target configuration. A method is provided for selecting one or more upgrade campaign specifications from a given set of upgrade campaign specifications. For each upgrade campaign specification, the method (1) identifies software and management operations specified in the upgrade campaign specification for upgrading the system; and (2) for each of a set of one or more scenarios defined in terms of operation execution time selection and execution mode, simulates upgrade of the system according to a corresponding arrangement of the software and management operations, thereby obtaining a corresponding execution time and a corresponding outage. A subset of the upgrade campaign specifications is rejected, for which the corresponding execution times do not meet an execution time threshold or for which the corresponding outages do not meet an outage threshold.

  • Patent number: 10466998
    Abstract: An upgrade campaign is generated for entities of a system described by a source configuration. According to the upgrade campaign, the system is upgraded to a target configuration using available software. A change model describes changes from the source configuration to the target configuration. According to the change model, an upgrade campaign specification model is generated, which contains at least one upgrade campaign element for each change in the change model. A subset of upgrade campaign elements are matched based on a first set of rules, and the matched upgrade campaign elements are merged into an upgrade procedure in the upgrade campaign specification model. The upgrade procedures are ordered based on a second set of rules and dependencies among the entities of the system, where the dependencies are extracted from the source configuration, the target configuration and the description of available software.

  • Patent number: 10282215
    Abstract: A system configuration is partially validated in response to requested changes to the system configuration. First, a reduced set of constraints is identified among a plurality of constraints of the system configuration. The reduced set of constraints place restrictions on attribute values and relations of changed entities to which the requested changes are applied. Each constraint of the reduced set is categorized based on leadership information that indicates an impact that a changed entity has on another entity with respect to the constraint. Each categorized constraint of the reduced set is validated to determine whether to accept, reject or modify the system configuration having the requested changes.
