This is a continuation of the earlier posts starting with this one: http://ravinote.blogspot.com/2020/09/best-practice-from-networking.html
Networking products embrace compute as much as the services that rely on networking but the line of separation between compute and networking layer remains clear in solutions that use networking. The purer the compute over the storage, the better for the storage.
For example, an application may use peer to peer networking or cluster mode with consensus messaging protocol but it tends to become simpler if the networking layer handles these.
A networking product may use a cluster for scalability or a peer to peer networking for distribution and offer this as a service so that the applications do not have to handle these.
The dependency of networking layer on a quorum of healthy nodes in an ensemble of a cluster is met with the help of detection and auto-remedial measures. If the administrator does not have to rush to replace a bad unit, it saves time and cost.
