Description
|
| Apache HTTP Server
|
A web server software. See https://en.wikipedia.org/wiki/Apache_HTTP_Server.
|
| CALM
|
Cloud Account Lifecycle Management. Our process for managing the allocation of cloud resources.
|
| Ceph
|
Distributed data storage platform, our standard storage software on the cloud.
|
| CephFS
|
Ceph File System, or a file system with Ceph storage, which allows data sharing on multiple instances (virtual machines, VM). Currently only available in the Arbutus cloud. https://docs.ceph.com/en/latest/cephfs/
|
| compute cloud
|
A RAS allocation type, corresponding to a cloud quota to use compute type flavors intended for iInstances (virtual machines, VMs) which will be running for a limited time and may require more CPUs or memory (RAM) during their entire lifespan. Flavors have labels beginning with “c”.
|
| CVMFS
|
CernVM-File System. A distributed read-only content distribution system often used for managing software.
|
| ephemeral disk
|
Virtual disk which is created and destroyed along with an instance (virtual machine, VM).
|
| flavour
|
The OpenStack term for a predefined specification of the compute, memory, and storage capacity of a new instance (virtual machine, VM).
|
| floating IP
|
An IP address that can be associated with an instance (virtual machine, VM) to allow external access.
|
| Horizon
|
The dashboard for OpenStack clouds that can be used for viewing and managing a user's cloud resources. https://docs.openstack.org/horizon/latest/
|
| host
|
The physical resources supporting an instance (VM, virtual machine).
|
| image
|
Short for "Virtual disk image". The cloud platform provides a set of prepared base operating system images. An image is used to create a new boot volume or ephemeral disk when launching a new instance.
|
| instance
|
A virtual server in the cloud infrastructure. Also known as a Virtual Machine (VM).
|
| IPV6
|
Internet Protocol version 6, a communications protocol and successor to IPv4. https://en.wikipedia.org/wiki/IPv6
|
| object storage
|
Persistent storage space for large amounts of data. Typically read access only, e.g. images and data sets.
|
| OpenStack
|
The software suite used on our clouds to control hardware resources such as computers, storage and networking.
|
| persistent cloud
|
A RAS allocation type for persistent instances (virtual machines, VMs) that are expected to run indefinitely and have low or bursty CPU requirements. Flavors have labels beginning with p*
|
| RAC
|
Resource Allocation Competitions. Program via which PIs can request storage and compute resources beyond what can be obtained via the Rapid Access Service (RAS).
|
| RAS
|
Rapid Access Service. Service by which Principal Investigators can request a modest amount of storage and cloud resources without having to apply to the Resource Allocation Competitions (RAC).
|
| S3
|
Simple Storage Service. A type of object storage. https://en.wikipedia.org/wiki/Amazon_S3.
|
| security group
|
A group of rules controlling network traffic to and from an instance (virtual machine, VM). A security rule can be applied as a whole to one or more instances.
|
| snapshot
|
A copy of a volume that can be used as a backup or to launch another instance (virtual machine, VM).
|
| SSL
|
Secure Sockets Layer. A protocol to allow encrypted communications over networks. SSL is now deprecated, and should be replaced by TLS (Transport Layer Security) wherever possible.
|
| SWIFT
|
Another type of object storage. https://wiki.openstack.org/wiki/Swift
|
| tenant
|
A group or user's allocation of cloud resources (now called a Project).
|
| TSL
|
Transport Layer Security. The successor of SSL (Secure Sockets Layer). https://en.wikipedia.org/wiki/Transport_Layer_Security
|
| VCPU
|
Virtual central processing unit. An instance (virtual machine, VM) can have one or more CPUs assigned to it, each of which is seen as a single physical CPU core by the operating system.
|
| VGPU
|
Virtual graphics processing unit. An instance (virtual machine, VM) can have one or more VGPUs assigned to it.
|
| virtual machine
|
See "instance."
|
| volume
|
An allocation of storage resources that can be attached or detached to/from an instance/VM, exposed as a block device (a virtual disk)
