US Patent 11451405 On-demand emergency management operations in a distributed computing system

Various methods and systems are provided for providing on-demand emergency management. On-demand emergency management includes emergency management operations (e.g., certificate update operations or managed-secrets rollover operations) for accelerated deployment and expedited installation of certificates or secrets. In operation, a host secret manager on a host machine communicates with client secret managers on virtual machines running the host machine, to provide expedited installation of secrets on the virtual machines. During the certificate update operations, the host secret manager communicates the certificate update secret package having a new secret state to a client secret manager that installs the new certificate state on the virtual machine. And, during managed-secrets rollover operations, based on accessing a managed-secrets rollover secret package having a notification-based new secret state, the host secret manager polls a dSMS service, and communicates with a client secret manager, such that client secret manager installs the new secret on the virtual machine.
