+
+## 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.

+old web site for now.
