Abstract
A cyclical patching process associated with a cloud application may be defined to ensure high availability (HA) of the cloud application in order to prevent impacting an availability to end users. A list of server identities corresponding to one or more servers of a datacenter hosting the cloud application may be accepted. HA metric values for each of the server identities may be determined in order to compute an overall HA metric value for the cloud application. A subset of the servers may be removed from a rotation framework of the cloud application based on the determined HA metric values, where the removal does not affect the overall HA metric value of the cloud application. One or more patches may be applied to each server within the subset of servers in parallel, and the subset of servers may be reinstated in the rotation framework of the cloud application.
