VergeIO Cloud refers to each autonomous Virtual Data Center (VDC) created within a VergeIO system. This includes the virtual data center created at the base level when VergeIO is installed on physical hardware, as well as the virtual data center that is created with each subsequent Tenant and sub-tenant.
Virtual Machine.
NOTE: The term “Machines” within the VergeIO software will refer to a more general workload object.
A Cluster is a group of Nodes (Physical or Virtual) with similar hardware resources used as a pool for storage, computing, or HCI functions. A System can contain various clusters to provide an array of performance / cost options. When creating VMs you can select the primary cluster on which to run the VM; you can also select a secondary or failover cluster.
A Recipe is a customizable template for launching new Virtual Machine instances. A VM Recipe includes initial hardware specifications (Number of cores, RAM, CPU type, drives, NICs, etc.) and resource pool specification. Additionally, custom fields can be added to the recipe to gather input at the time of recipe consumption. This data, input by the recipe consumer, can then be utilized to adjust elements within the new VM guest OS, typically at first startup. For example, a Recipe can be configured to prompt for a database username and password, or disk / ram size settings to input into an application configuration file. VergeIO VM Recipes are also compatible with Cloud-init.
A Snapshot captures the state of an entity at a particular point in time. Snapshots can be used to create point-in-time capture of an entire VergeIO Cloud, Tenant, an individual VM, or a NAS volume. Snapshots allow "rolling back" a system, which can be helpful for recovery, development, and testing purposes.
