The term "ansible" was coined by Ursula K. Le Guin in her 1966 novel Rocannon's World, [4] and refers to fictional instantaneous communication systems.[5] [6]The Ansible tool was developed by Michael DeHaan, the author of the provisioning server application Cobbler and co-author of the Fedora Unified Network Controller (Func) framework for remote administration.
This level of control enables the cluster to support upgrades and patches of the control plane nodes with minimal effort. The compute nodes can be running Red Hat CoreOS, RHEL or even Windows. OpenShift introduced the concept of routes - points of traffic ingress into the Kubernetes cluster. The Kubernetes ingress concept was modeled after this ...
The Kubernetes API can be extended using Custom Resources, which represent objects that are not part of the standard Kubernetes installation. These custom resources are declared using Custom Resource Definitions (CRDs), which is a kind of resource that can be dynamically registered and unregistered without shutting down or restarting a cluster ...
The metadata server cluster can expand or contract, and it can rebalance file system metadata ranks dynamically to distribute data evenly among cluster hosts. This ensures high performance and prevents heavy loads on specific hosts within the cluster. Clients mount the POSIX-compatible file system using a Linux kernel client.
Windows NT Server 4.0, Enterprise Edition was the first version of Windows to include the MSCS software. The software has since been updated with each new server release. The cluster software evaluates the resources of servers in the cluster and chooses which are used based on criteria set in the administration module.
ONTAP Cluster could consist only with even number of nodes (they must be configured as HA pairs) except for Single-node cluster. Single-node cluster ONTAP system also called non-HA (stand-alone). ONTAP Cluster managed with a single pane of glass built-in management with Web-based GUI, CLI (SSH and PowerShell) and API.
The docker swarm CLI [37] utility allows users to run Swarm containers, create discovery tokens, list nodes in the cluster, and more. [38] The docker node CLI utility allows users to run various commands to manage nodes in a swarm, for example, listing the nodes in a swarm, updating nodes, and removing nodes from the swarm. [ 39 ]
