A computer-implemented method comprises detecting, by a processor of a first host of one or more hosts in a distributed computing environment, a distributed task waiting to be started, from a replicated configuration system, the distributed task being represented by a pending tasks key. The method comprises starting, by the processor, the distributed task by performing an atomic compare and swap operation to add a started key to the replicated configuration system. The method also comprises writing a specification of the distributed task to the replicated configuration system under a new version of a current tasks key. In addition, the method comprises removing, following the writing, the pending tasks key from the replicated configuration system.

Fault-tolerant and highly available configuration of distributed services

Systems and methods are provided for managing states of deployment. A presence of a configuration change to be implemented at a deployment may be detected. The configuration change may include one or more commands to change a configuration of the deployment. Responsive to detecting the presence of the configuration change, information describing the configuration change may be stored in a repository. The information may be stored in an unsubstituted form and a substituted form. An interface through which configuration change information is accessible may be provided. The configuration change information may describe the configuration change at the deployment based on one or both of the unsubstituted form and the substituted form.
