Terms in this definition
- ESX
VMware's bare-metal hypervisor, installed on each host in a VCF fleet. Up to version 9.0 it was known as ESXi.
- Event
Table in Log Analytics where entries from Windows event logs are kept.
- CRUD
Shorthand for create, read, update and delete, the four basic things you do with data. Data-plane roles in Azure Cosmos DB, for instance, authorise those operations on items.
- vCenter
Management software for VMs, clusters and ESX hosts. Each domain in VCF gets a dedicated one.
- vSAN
VMware's software-defined storage, which combines local devices across a cluster's ESX hosts into one shared datastore. Available as OSA or ESA, VCF can use it as principal storage.
- IDS
Security tooling that observes network traffic. Failed migrations can result if it, or a firewall, stops vMotion ports getting through.
