Status sharing in a resilience framework
An example framework and method facilitate enhancing resiliency of a computing environment. The example method includes dynamically discovering or accessing first status information related to a first metric associated with a first resource of the computing environment; selectively sharing the first status information among one or more computing environment resources, including the first resource, resulting in shared status information; and using the shared status information to selectively initiate one or more responses by the one or more resources in accordance with the shared status information. In a specific implementation, metrics managers may manage metrics and initiate remediation actions when certain criteria are met; the resources can selectively quiesce or unquiesce when the certain criteria are met or when their status changes accordingly; and a resiliency manager may coordinate communications between metrics managers and computing resources. Use of MBeans may facilitate pluggability of resources into the resiliency framework of the computing environment.
