Abstract:
In a computer-implemented method for calculating a performance metric of a cluster of hosts in a virtualization infrastructure a performance metric of each of a plurality of virtual machines in said virtualization infrastructure is accessing by a centralized management application of a virtualization infrastructure. The virtualization infrastructure comprises a plurality of hosts supporting the plurality of virtual machines. A performance metric of a cluster of the plurality of hosts is calculated by the centralized management application based on the performance metric of each of the plurality of virtual machines hosted by the cluster. The calculated performance metric of the cluster is transmitted to a database such that a history of performance metrics of the cluster are stored in the database.
Abstract:
Hosts in a cluster in a virtualized computing environment bypass a management layer when communicating with an external key management service (KMS). One of the hosts is configured with KMS configuration information (including digital certificate information) that enables the host to directly communicate with the KMS via a secure communication connection, instead of communicating with the KMS via the management layer. This KMS configuration information is replicated in a distributed manner from the host to the other hosts in the cluster, thereby enabling the other hosts in the cluster to also directly and independently communicate with the KMS to obtain encryption keys to perform cryptographic operations.
