Abstract: The disclosure relates to a method and a state controller running in a Kubernetes system. The state controller being operative to assign labels to pods, the labels indicating services to which the pods are assigned and high-availability states of the pods; detect a failed pod having a label indicating a high-availability state of not ready; and reassign the label indicating the high-availability state of the failed pod to a healthy pod, thereby changing endpoints of services provided and service flows from the failed pod to the healthy pod.

Abstract: The disclosure relates to a method, system and computer readable media for validating that a configuration of a cloud system meets requirements, using a reduced test suite selected from a test suite. The method includes classifying the requirements and service instances realizing the requirements composing the cloud system. The method includes applying test suite reduction rules to the test suite, using the classified requirements and service instances, to obtain the reduced test suite. The method includes applying the reduced test suite to the cloud system configured with the configuration, thereby validating that the configuration of the cloud system meets the requirements.

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.
