In an ACOS cluster, the witness node is located in another data center outside the data centers where the two availability zones reside. It ensures the normal operation of master node election in the ACOS active-active cluster and supports automatic service switchover between the primary and secondary availability zones.
In the context of ANS controllers, a witness node refers to an ANS controller witness node.
In the centext of AOC, a witness node refers to the arbitrator of the high-availability cluster. The witness node does not store service data and is primarily responsible for monitoring the health status of the active and passive nodes and responding accordingly. In specific failure scenarios, it initiates automatic failover to ensure the continuous availability of AOC.
In an AKE cluster, a worker node runs containerized workloads.
In the context of ANS controllers, a worker node refers to an ANS controller worker node.
A Kubernetes cluster created through AKE for deploying workloads, including VM-based workload clusters and physical-machine-based workload clusters.
One of the default roles provided by AOC, which has the permission to view the list of workload clusters to which it belongs.
