Introduction

Part 1 built the foundation of a file portal on top of Amazon FSx for NetApp ONTAP (FSx for ONTAP) S3 access points. Part 2 added ransomware response and WORM retention. Part 3 put AI agents on it.

Those parts were screens for people who handle files. From here the subject is the people who operate the storage itself. Volume create and resize, FlexCache, FlexClone, SnapMirror, snapshot policies, QoS, quotas, SMB shares. The portal now reaches 182 operations.

The readers I have in mind are infrastructure owners running FSx for ONTAP, and developers building this kind of admin screen with Amplify Gen2. ONTAP terms get a one-line gloss on first use, so ONTAP operations experience is not assumed. You can start here without Parts 1-3.

What this part covers is what had to be decided to put operations on a screen: the design of delegation and record, and the treatment of buttons that cannot be pressed and buttons that were never built.
