ElastiCache on Scaleway: what it becomes and what it costs.
On Scaleway, ElastiCache becomes Valkey on Scaleway Instances, or a Scaleway managed database. Protocol-compatible. On Hetzner you run it yourself; where the destination sells the managed engine (DigitalOcean, OVHcloud and Scaleway for most of them) it costs roughly twice the bare server, still well under today's price.

Same software, self-hosted: you patch, back up and fix it
Cost after the move, before engineer time

cache.r6g.large (13 GB) is $0.206/h = $150/mo; a CX43 (16 GB) is €16.49 ≈ $19, so about 15% raw; with persistence, a replica and headroom, 35%.
Engineer time
6 h a month
To run the replacement: patching, backups, on-call. Plus about 5 engineer days for the move itself.

The report lets you pick any of these per service; the figure and the grade follow.
Managed Valkey / Redis at Scaleway, or a Scaleway managed database
Where Scaleway sells a managed cache, persistence and failover stay someone else's job; about twice the bare server.
