Moderate to move
Cloud Armor on Vultr: what it becomes and what it costs.
On Vultr, Cloud Armor becomes Cloudflare WAF or ModSecurity / Coraza. Rules need rewriting; a CDN-level WAF is the usual choice.
Effort grade
Moderate
Same software, self-hosted: you patch, back up and fix it
Cost after the move, before engineer time
50% of today
Self-hosted equivalent sized like the managed one: server plus storage at destination prices comes to roughly 50% of today; the operations work is counted as engineer time, not here.
Engineer time
6 h a month
To run the replacement: patching, backups, on-call. Plus about 5 engineer days for the move itself.
