Glossary
A
access key
Credentials (login, password, API key, Certificate Authorities (CAs)) used to access, use, and manage services. Access keys are linked to a specific account and shall be kept private. An access key is also referred to as access key / secret key (or AK/SK).
For more information, see About Access Keys.
B
beta service
Service provided by 3DS OUTSCALE as a test version before large-scale deployment. Beta services are identified as such in the public documentation. The APIs and resources created and used in beta services are not guaranteed. 3DS OUTSCALE reserves the right to modify or delete beta services without notice.
C
Cloud computing
Memory, compute, storage, and network resources provided by networked servers. Those servers and their underlying infrastructure are operated and managed by OUTSCALE.
Container
A lightweight virtual environment enabling an application to be isolated and run autonomously. A Container uses the resources (CPU, RAM, Storage, networking) of its host (Cloud VM or server), and is designed to bring together an application’s code and all its dependencies, to make that application autonomous (in its execution), modular, portable, standardized, and easily deployable on any operating system.
Control Plane
A set of Cloud VMs or servers running software components designed to scale the Cluster and manage Nodes and Pods. Among these software components are:
-
A “kube-apiserver” API server for communications within and to the Cluster,
-
An “etcd” that stores data on cluster events and status,
-
A “kube-scheduler” for managing Node resources.
I
instance
See the entry VM.
K
Kubernetes (or K8S)
An open source container orchestration software for deploying, managing, coordinating, and scheduling large-scale Containers. Kubernetes organizes Containers into Pods and runs these Pods on Nodes.
See the entry OKS.
Kubernetes Cluster
A set of resources consisting of a group of Nodes and a Control Plane.
N
Node (or worker node)
A Cloud VM, or server, running Pods within a Kubernetes Cluster.
Node pool
A set of VMs controlled by a Control Plane and directly running the workload of the OKS cluster. Usually Node pools include Nodes which have some similarities (in resources available, usage purpose, geographical placement, etc.). Note that a Cluster can have multiple node pools at the same moment.
O
object storage service
Storage environment which allows outbound and inbound flow of data from a platform through the internet, including a copy of the data on at least two physical equipments. This copy ensures data sustainability in case of simultaneous failures of one or both equipments used.
OKS
OUTSCALE Kubernetes as a Service (OKS) is an Infrastructure as a Service which provides managed Kubernetes service.
For more information, see About OKS.
OMI
OUTSCALE Machine Image ready to use and available on OUTSCALE platforms to provide one or more preconfigured VMs.
For more information, see About OMIs.
official OMI
OMI identified in the list of available OMIs provided by OUTSCALE.
For more information, see Official OMIs Reference.
P
Pod
A basic unit in Kubernetes, grouping one or more Containers sharing Pod resources and hosting applications.
R
Region
Geographical area where Cloud resources are hosted.
For more information, see About Regions and Subregions.
reserved VM
VM which can be reserved in a specific Region and linked to an account for a specific duration.
For more information, see Reserved VMs.
S
snapshot
Point-in-time image of a volume (its data and metadata).
For more information, see About Snapshots.
Subregion
One or several close locations in a Region where OUTSCALE deploys the equipments required for providing services.
For more information, see Subregions.
system
Applications, developments, data, database, software, etc. installed one or more VMs or an object storage service, to make them accessible on the internet or through a direct connection.
V
VM
Virtual Machine(s) or servers deploying the systems, located in the OUTSCALE infrastructure. The servers are composed of:
-
Memory resources (RAM and hard disk and/or any other type of storage device)
-
Compute resources
-
Persistent storage, with or without guaranteed performance
-
An operating system (Windows®, LINUX, etc.)
-
Third-party applications, requiring or not a license
-
Standardized security systems
-
An allocation of bandwidth
VMs are also referred to as instances.
For more information, see About VMs.
