Abstract: An example method of hypervisor lifecycle management in a virtualized computing system having a cluster of hosts is described. The method includes: obtaining, by remediation software executing in a host of the hosts, a host state document from a distributed key-value store, the host state document defining a desired state of software in the host, the software including a hypervisor; and performing, by the remediation software in coordination with other hosts of the hosts through the distributed key-value store, a lifecycle operation on the software of the host in response to determining that a current state of the software does not match the desired state.

Abstract: In a computer-implemented method for automated provisioning a certificate in a computing system a certificate signing request is accessed from a computing node by a centralized management tool of the computing system. The certificate signing request is provided to a certificate authority by the centralized management tool. A signed certificate is accessed from the certificate authority for the computing node. The signed certificate is provided to the computing node, by the centralized management tool, such that there is automated provisioning of the signed certificate at the computing node to establish trust of the computing node in the computing system.

Abstract: In a computer-implemented method for automated monitoring certificate expiration, automatically periodically accessing a plurality of computing nodes in a computing system for certificate expiration of a certificate of the plurality of computing nodes. The automatically periodically accessing is provided by a central management tool of the computing system. Automatically determining the certificate of the plurality of computing nodes has an impending certificate expiration by the central management tool of said computing system. In response to the determining, automatically generating an alert, by the central management tool, that indicates the impending certificate expiration of the certificate.

Abstract: A technique for booting a computing device using a boot image that is downloaded from a distributed network booting system involves identifying a tracker computing device that manages a plurality of computing devices that store all or a portion of the boot image, receiving from the tracker computing device information about one or more computing devices from which to download the boot image, and downloading the boot image from the one or more computing devices.
