Do we still need EFS CSI driver?

[poornima-krishnasamy]

Background

The Cloud Platform cluster has AWS EFS Driver installed. It is not configured for actual use by CP users. Also, its runs as a daemonset, and is not up to date.

There are discussions around moving the chart as a efs-utils addon and installed by system-manager.

We should consider what we want to do about this component. It probably should be deleted, but prior to this we should see if there is a suitable NFS like / read-write-many solution that is now available for us to look at.

If found, create ticket for spiking.

Proposed user journey

There is also no urgent user need from user: #3994

Approach

Investigate if there is still a user need for this module or else, remove the installation from the cluster.

How to write good user stories

Can we loop in Data Platform to a conversation on this as in conversation they have expressed interest in requiring EFS for a service.

[sj-williams]

At this time, Analytical Platform tooling EFS requirement is paired with their request for dedicated node group(s) with custom compute as well. Unless/until this becomes an option EFS is off the table.
