+title: 'Preferring diskless flavors in SCS'
+author:
+  - 'Kurt Garloff'
+---
+
+## Purpose
+
+Sovereign Cloud Stack (SCS) downgraded the formerly mandatory flavors with
+root disks to recommended ones when the flavor naming standard version 3
+became effective in the fall 2023. For many users using flavors that comprise
+a root disk is still the standard and at least when using CLI tooling,
+it's also simpler.
+
+This article documents how the diskless flavors can be used with common
+IaC tooling.
+
+## Link to blog article
+
+We covered this in a blog article before, for which we
+[link here](https://scs.community/2023/08/21/diskless-flavors/) to our
+old web site for now.
