A secret a service account sends as a bearer token to
call the API. Shown once when issued.
Catalog
What a location offers: instance sizes, images, volume types and load balancer types.
Certificate
A TLS certificate with its private key, served by HTTPS load balancer listeners.
Cloud credential
An OpenStack application credential for one project, in its location, for unattended tools.
Default certificate
The certificate an HTTPS listener serves to clients whose host name matches none of its other
certificates. See SNI.
Horizon
A location's own OpenStack dashboard.
Idempotency key
A value you send with a change so that sending it again does not make it twice.
Image
A saved system disk that instances start from: the location's, or one of your own.
Instance
A virtual machine in a project's location.
Instance group
A number of instances from a launch template, kept running.
Internet gateway
Outbound Internet access for a project's routed networks.
Launch template
Saved, versioned instance settings to launch one to ten instances like it.
Listener
The protocol and port a load balancer answers on.
Load balancer
One address that spreads traffic over a pool of instances.
Location
One of NubeStack's independent clouds: Karachi (pak-khi-1) or Islamabad (pak-isb-1). Each
project runs in one.
Nexus
The platform NubeStack Cloud runs on. The console shows the name in a few places: Created by:
Nexus for resources NubeStack Cloud made for you, outside Nexus for resources made with a
location's own tools, and possibly on a location's sign-in page. It is not a different account.
Operation
The record of a change being carried out in a location, from accepted to its final state.
Organization
Your account: its people, projects, roles, quota and usage. Also the console's scope for
managing them.
Placement
In the API, a project in its location (plc_…), for example in quota and Internet gateway
routes. A project has one.
Pool
The instances a load balancer listener sends traffic to, with a balancing method.
Price estimate
On a create page, what the new resource would cost per hour or per month at NubeStack's
current rates. Provisional.
Project
A group of resources and the people who may use them, in one location.
Provisional
Still being checked: usage and cost figures may change and are not a bill.
Public IP
An address that makes one instance or load balancer reachable from the Internet. floating-ips
in the API.
Quota
How much a project may hold, shared out of the organization's budget in its location.
Routed network
A network attached to the project's private router in its location.
Scope
What the console shows: the organization, or one project. Chosen in the scope selector at
the top.
Schedule
Something that runs on a timetable: backups, power, or an instance group's size.
Security group
Firewall rules for instances and load balancers. Rules allow; nothing denies.
Server group
A rule to place instances on different hosts, or together.
Service account
An identity for automation, with roles, API keys and cloud credentials. A personal service
account is one person's, on one project.
SNI
Server Name Indication: the host name a client asks for when it starts TLS, which lets one
listener serve a different certificate for each domain.
Snapshot
A point-in-time copy of a volume, on the same storage.
SSH key
A public key copied into new instances so you can log in.
Subnet
A network's address range, with its gateway, DHCP and DNS settings.
Tag
A key: value label to filter lists and break down costs.
Volume
A disk that keeps its data apart from any one instance.
