Discussion
----------

Find an Openshift storage backend solution so applications can use persistent
volumes/storage when needed.

What would be needed
--------------------

The AWS EFS operator can be installed from the Operator Marketplace to provision volumes
in Openshift.

There is a problem where each volume requires an access point to be created in a file
system in AWS, this is a manual process.

This process can be automated with an ansible playbook as each PVC object will need its
own access point but requesting storage for a namespace can be asked through an infra
ticket.

AWS does not apply any limits to the created volume that control needs to be managed in
Openshift.

Conclusion
----------

The AWS EFS operator is the most straightforward path to support persistent storage in
Communishift.

There is a manual step which requires the creation of an access point in AWS but that
can be automated with ansible.
