Abstract: A configuration is generated for a software that is to be deployed for providing high service availability to satisfy configuration requirements. One or more configuration patterns are identified, each of which specifies a set of attribute values and an actual recovery action for a failed component as a configuration option of the software. The unchangeable attribute values of the software are matched with the configuration patterns to obtain a matching configuration pattern, whose actual recovery action incurs a smallest component failure recovery impact zone. The matching configuration pattern is selected as at least a portion of the configuration of the software. Then the changeable attribute values of the software are set to the corresponding attribute values of the matching configuration pattern to satisfy the configuration requirements.

Abstract: A system is adapted to generate a configuration for a service provider system to provide a highly available (HA) service. The system first identifies type stacks that provide the HA service and one or more component types in each type stack. Each type stack is a combination of prototypes that describe features and capabilities of available software providing the HA service. The system estimates, for each component type in the type stacks, a mean-time-to-recover (MTTR) of the HA service based on time for completing an actual recovery action in response to a component failure. The system further estimates service availability provided by each type stack based on the MTTR and a mean-time-to-failure (MTTF) of each component type in the type stack. The system then eliminates one or more of the type stacks that do not satisfy a requested service availability before proceeding to subsequent steps of configuration generation.
