Abstract: The disclosure provides an example method for configuring a cluster of hosts. The method generally includes defining a global transport node profile that defines a first configuration for the cluster of hosts, defining a sub-transport node profile that defines a second configuration, assigning one or more hosts of the cluster to the sub-transport node profile and configuring the cluster of hosts based on the global transport node profile and the sub-transport node profile comprising: configuring the one or more hosts of the cluster based on the first configuration and the second configuration; and configuring at least one host of the cluster not assigned to the sub-transport node profile based on the first configuration and not the second configuration.

Abstract: The current document is directed to methods and systems that carry out live migration of multi-node applications in distributed-computing systems, including cloud-computing applications in cloud-computing facilities. The disclosed methods and systems employ an installer/agent and a data-transformation component to install new versions of a multi-node application within a distributed computing system and to then warm start each application-provided service within the newly installed new-version application nodes. Following a data sync operation, each warm-started application service is brought online to service subsequently received service requests as older-version corresponding services of current application nodes complete request services and terminate, providing live migration from an older version multi-node application to a new-version multi-node application without service-provision interruption.

Abstract: The current document is directed to automated application-release-management facilities that, in a described implementation, coordinate continuous development and release of cloud-computing applications. The application-release-management process is specified, in the described implementation, by application-release-management pipelines, each pipeline comprising one or more stages, with each stage comprising one or more tasks. The currently described methods and systems employ configuration files to specify configuration of the execution environment for application-release-management pipelines, application-release-management-pipeline stages, and application-release-management-pipeline-stage tasks.
