Hard to move
Cosmos DB on Vultr: what it becomes and what it costs.
On Vultr, Cosmos DB becomes ScyllaDB or PostgreSQL with a data-model rewrite, or a Vultr Managed Database. Multi-model proprietary API; access patterns need re-modelling.
Effort grade
Hard
No equivalent: redesign it, buy a SaaS, or leave it where it is
Cost after the move, before engineer time
50% of today
100 RU/s is $5.84/mo, so a 10k RU/s workload is $584; ScyllaDB on three CX33 (€25) or Managed MongoDB, about 50% before the rewrite.
Engineer time
16 h a month
To run the replacement: patching, backups, on-call. Plus about 15 engineer days for the move itself.
