摘要： An Availability Management Framework (AMF) configuration describes how configuration entities of a highly available system are grouped and includes information on service provision and service protection policies against resource failure. The AMF configuration defines a set of failure types for each component and each node, and specifies a failure rate and a recommended recovery for each failure type. A method for evaluating service availability receives the AMF configuration as input, and analyzes it to obtain an actual recovery that the highly available system is to perform when the given component fails. The method maps the AMF configuration to a stochastic model that captures the dependencies among the components and among the configuration entities at multiple levels of the hierarchy. The method utilizes the model to calculate the service availability of the AMF configuration based on the failure rate, the actual recovery and the dependencies.

摘要： Redundancy models are compared to determine or assist in determining an Availability Management Framework (AMF) configuration of a highly available system based on quantified service availability of the system. Each redundancy model defines assignments of service-instances to service-units. An analysis model of the system is constructed to capture recovery behaviors of the system for each redundancy model. Service availability of the system is quantified based on the analysis model under one or more scenarios including failure scenarios and recovery scenarios. Based on a comparison of service availability levels provided by the redundancy models and subject to constraints of the HA system, one of the redundancy models is identified that provides a required level of service availability for the system.

摘要： A Service Level Agreement (SLA) is specified for a component. To satisfy the SLA, a system receives a component profile describing expected resource consumption of the component, and identifies available resources for an execution environment to execute the component. A component recovery time is calculated for a redundancy model supported by the component and for an execution environment composition supported by the available resources. The component recovery time includes a time duration for each phase in a set of phases of component recovery. The system also determines resource allocation based on the calculated component recovery time to satisfy a recovery time objective specified in the SLA.

摘要： A middleware that manages high availability of a software application is automatically configured when the software application is added to a system. The method of automatic configuration includes receiving a user input that specifies availability requirements and information of the software application, where the availability requirements include at least a checkpoint service that enables the software application to save and retrieve its state. The method also includes identifying a checkpoint agent for providing the checkpoint service to the software application. The checkpoint agent includes a first interface to the software application and a second interface, different from the first interface, to the middleware. A middleware configuration is generated that satisfies the availability requirements, based on the information of the software application such that the middleware offers the checkpoint service to the software application through the checkpoint agent and directly manages lifecycles of the software application.

摘要： Configuration requirements for an Availability Management Framework (AMF) configuration are generated from high level user requirements that specify a subset of properties of an AMF configuration. The user requirements are first mapped into entity prototypes defined in an extended Entity Types File (ETF) model. A computer system identifies additional entity prototypes and dependency thereof that support functionalities of the mapped entity prototypes under a set of grouping conditions. The computer system calculates the required number of component service instances (CSIs) and service instances (SIs) that satisfy the user requirements. The calculation is based on the subset of the properties specified by the user requirements and measurements associated with the entity prototypes in the extended ETF model. The computer system then forms configuration requirements including the required number of CSIs and SIs for generating the AMF configuration that satisfies the user requirements.

摘要： Systems and methods are provided for processing requests, received from clients and peer nodes, in a leaderless cluster of nodes. A node can initiate a read or a write operation in the cluster. The node can solicit votes from its peer nodes in order to confirm that the requested operation should be performed. A threshold number of positive responses, such as a supermajority of the nodes in the cluster, can be required in order to confirm the requested operation.
