Docker Certified Associate Certification Training Course - Quorum in a Swarm Cluster

The video tutorial explains the importance of quorum in Docker Swarm clusters, focusing on the role of manager nodes in managing the swarm state using the Raft consensus algorithm. It discusses the trade-offs between performance and fault tolerance when deciding the number of manager nodes. The tutorial emphasizes the need for a quorum to ensure fault tolerance and provides guidelines for maintaining it, recommending an odd number of managers to facilitate quorum maintenance.

What happens to the swarm if it loses quorum among the manager nodes?

Why is it recommended to have an odd number of manager nodes in a swarm?
