摘要： Presented are methods and apparatus for protecting a plurality of High Availability (HA) Service Instances (SIs) with a plurality of Service Units (SUs) with an Nway redundancy model. Any of the SUs associated with the Nway redundancy model can simultaneously be assigned an active HA state for some of the SIs and a standby HA state for other SIs. However, only one SU can have the active state for any given SI. The Nway redundancy model is a configured prior to runtime operation.

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： Among other things, embodiments described herein enable systems, e.g., Availability Management Forum (AMF) systems, having service units to operate with balanced loads both before and after the failure of one of the service units. A method for balancing standby workload assignments and active workload assignments for a group of service units in a system which employs an N+M redundancy model, wherein N service units are active service units and M service units are standby service units is described. An active workload that the N active service units need to handle is calculated and each of the N active service units in the group is provided with an active workload assignment based on the calculated active workload. Standby workload assignments are distributed among the M standby service units substantially equally.

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： An Entity Types File (ETF) is automatically generated from a high-level software description, where the software description describes software to be managed by middleware to achieve high availability. An ETF generation method comprises receiving the software description that describes interfaces and dependency between components of the software; verifying the software description in accordance with constraints imposed by middleware specifications; based on the verified software description, automatically creating a hierarchy of entity types and associations among the entity types compliant with the middleware specifications; and outputting the entity types and the associations as the ETF for subsequent generation of a configuration of the middleware for availability management.

摘要： Cloud computing is continuously growing as a business model for hosting information and communications technology applications. While the on-demand resource consumption and faster deployment time make this model appealing for the enterprise, other concerns arise regarding the quality of service offered by the cloud. The placement strategy of the virtual machines hosting the applications has a tremendous effect on the High Availability of the services provided by these applications hosted in the cloud. Systems and methods for scaling a virtualized application that take into consideration the interdependencies between the components of the applications and other constraints such as the communication delay tolerance and resource utilization are provided.
