Managing continuous priority workload availability and general workload availability between sites at unlimited distances for products and services

Abstract

A system for providing reliable availability of a general workload and continuous availability of a priority workload over long distances may include a first computing site configured to execute a first instance associated with the priority workload, wherein the first instance is designated as an active instance, a second computing site configured to execute a second instance of the priority workload, wherein the second instance is designated as a standby instance, a third computing site configured to restart a third instance associated with the general workload, and a workload availability module configured to synchronize a portion of data associated with the third instance with a corresponding portion of data associated with the second instance.

What is claimed is: 
     
         1 . A system for providing reliable availability of a general workload and continuous availability of a priority workload over long distances, comprising:
 a first computing site configured to execute a first instance associated with the priority workload, wherein the first instance is designated as an active instance;   a second computing site configured to execute a second instance of the priority workload, wherein the second instance is designated as a standby instance;   a third computing site configured to restart a third instance associated with the general workload;   a workload availability module configured to:
 synchronize a portion of data associated with the third instance with a corresponding portion of data associated with the second instance; 
 resolve a data inconsistency between the portion of data associated with the third instance and the corresponding portion of data associated with the second instance based on the portion of data associated with the third instance being obsolete; 
 designate the second instance as the active instance and designate the third instance as the standby instance; and 
 monitor a metric associated with the first computing site and determine the first computing site is unavailable based on the metric; and 
   a hardware replication module configured to replicate an image from a first storage volume to a copy on a second storage volume, wherein the first storage volume is associated with the first computing site, and the second storage volume is associated with the third computing site,   
       wherein the second computing site is separated from the first computing site by a first distance greater than a metropolitan area network, and the third computing site is separated from the first computing site by a second distance greater than the metropolitan area network.
