A

Access Control

Access Control is a component of a billing plan (bucket) where you add resources that will be available to users of the billing plan. 

Accelerator

Accelerator is a type of a virtual appliance that serves as a router for traffic between OnApp CDN and virtual servers. You can enable Accelerator on a network level and, as a result, CDN is enabled for virtual servers that use this network. 

API 

OnApp API is RESTful, supports XML and JSON formats, and requires authentication or authorization (Basic HTTP or API key). 

Asset 

Asses is a compute resources that is added to Control Panel but is not set up or associated with any compute zone. 


B

Backup Plugin System

Backup Plugin System is a system that enables you to integrate OnApp with third-party backup services, such as R1soft, Veeam and others. The plugin allows you to back up and restore your virtual servers by means of a service that you use for backup management.

Bucket 

Bucket is a billing plan where you add resources (Access Control), free limits, and prices (Rate Card) for the usage of these resources. You can assign a bucket to users and user groups for them to have access to cloud resources. If a user is not associated with any bucket, the user has no access to available resources. 


C

Catalog

A catalog is a container for vCloud Director vApp templates and media files in an organization. 

CloudBoot

CloudBoot is a method of a compute resource installation without the presence of a local disk or other local storage, utilizing the PXE and DHCP servers. CloudBoot compute resources can run on Xen or KVM virtualization. 

Compute Resource

A compute resource is a hypervisor or virtual machine monitor that is used to create and run virtual servers on OnApp. 

Compute Zone

A compute zone is a grouping of resources, such as compute resource, data store, network, and backup server that all belong to the same type. The available types of compute zones are Virtual, Smart, Baremetal or VPC. You can select a type of a compute zone and group other resources, depending on the appliances that you want to use in your cloud: Virtual - virtual servers, Smart - smart servers, Baremetal - baremetal servers, VPC - vCloud Director virtual servers. 

Control Panel 

Control Panel is a web-based user interface that you can access to handle all cloud management processes. Control Panel runs on a physical server that hosts OnApp user interface and database. 


D

Dashboard

Dashboard is a page that you can see after you log in to Control Panel. The Dashboard page provides the resource usage statistics, activity log, and your cloud summary. 


E

Edge Getaway 

Edge Getaway is a virtual router for networks included into a Resource Pool (VDC). Edge Gateways provide a routed connection between an organization VDC network and an external network. 


F

Federation

Federation is a central trading system that connects sellers, buyers, and users to give each OnApp partner a global reach and more capacity. Any accredited seller can sell resources through marketplace and any hosting partner can access the global market of supply.  


H

Hardware Info

Hardware Info is a page on Control Panel that provides an overview of hardware that is used by Xen and KVM compute resources and backup servers.

Help

Help is a menu on you Control Panel that enables you to submit support requests to the OnApp team. All the requests received via Help are considered to be sent on behalf of a cloud owner from a trusted source. 


Instance Package

An instance package is a preconfigured environment with a specific compute, storage, and network capacity used to create a virtual server instead of a custom set of resources. 

Integrated Storage

Integrated Storage allows a cloud admin to build a highly scalable and resilient SAN storage target for virtual server storage, using local disks on compute resources. With Integrated Storage, you can create a virtual data store in your cloud that spans multiple physical drives on compute resources with RAID-like replication and striping across drives.


K

Kdump

Kdump is a Linux kernel crash dumping mechanism that exports a memory image that you can analyze to determine a cause of a kernel crush. You can enable Kdump on KVM compute resources based on CentOS 6 and CentOS 7. 


L

Look & Feel

Look & Feel is a menu that enables you to add themes to customize the appearance of your Control Panel UI. 


M

Maintenance Mode

Maintenance Mode is a mode that you can enable on static and CloudBoot compute resources on Xen and KVM to temporarily take a resource out of service in order to run fixes or upgrade procedures. 

Manual IP Net

Manual IP Net is created while importing vCenter virtual servers to OnApp Control Panel under the following conditions: an IP address attached to a virtual server does not belong to an IP range available in any vCenter network on CP.   


N

Notifications 

Notifications are email notifications that you can set up on your Control Panel to notify users about specific events taking place in a cloud.


O

Orchestration Model

Orchestration Model is a preconfigured environment with a specific compute, storage, and network capacity used to create a vCloud Director virtual server. 


P

Provider Resource Pool

Provider Resource Pool is a term used to refer to a Provider Virtual Data Center (Provider VDC) in vCloud Director. Provider Resource Pool is an allocation model that determines how and when compute, memory, and storage resources are delivered from a provider VDC to an organization VDC.


R

Rate Card

Rate Card is a component of a billing plan (bucket) where you add prices for the usage of resources that will be available to users of the billing plan. 

Recipe

A recipe is a plug-in mechanism where you declare a set of instructions to trigger actions at certain stages during the execution of certain events in the cloud. Recipes run over SSH and all commands triggered by recipes can run on templates, appliances, such as virtual and other types of servers, compute resources, and the Control Panel server. 

Resource Pool

Resource Pool is a term used to refer to a Virtual Data Center (VDC) in vCloud Director. Resource Pool is an allocation model that determines how and when compute, memory, and storage resources are delivered from an organization VDC to user groups.


S

Service Add-On

A service add-on is a tool that enables you to provide your customers with additional services on top of your current offering. You can use service add-ons to run recipes or send notifications when a certain event occurs on a destination virtual server. 

Service Insertion Framework

Service Insertion Framework is a framework that allows you to bring other services to OnApp. When you create service insertion groups and pages, they become available on the main menu on your Control Panel.

Smart Server 

Smart Server is a virtual server that runs on a CloudBoot KVM-based compute resource and is the only guest machine deployed on the host. 

Static Resources

Static resources are compute resources that run on Xen or KVM virtualization environment and make use of the local, shared, or OnApp Integrated Storage.  


V

vApp

vApp is a preconfigured environment comprised of one or more virtual servers that communicate over a network and use resources to work together in a stack.

vApp Template

A vApp template is a virtual server image loaded with an operating system, data, and applications. When you create a vApp, you can select one or more vApp templates from which to create virtual servers. 

Virtual Server (VS)

A virtual server (VS) is a term used to refer to a virtual machine (VM).


W

White List 

White List is a list of IP addresses from which a particular user can access OnApp Control Panel UI. If some IP addresses are added to White List for a particular user, the user can access CP only from these IP addresses.
