I guess I am saying it's a good value more than its raw price being less than other offerings.
The blue/green deploys, auto snapshotting, failover, upgrades, few-click resizing, etc justify the price vs running database servers (for me). I spend a lot of time looking for money in aws and never consider replacing RDS with anything else.
Scaleway costs approximately 51 % less, looking at on-demand postgresql instance with 8 GB RAM (db.t3.large vs. db-dev-l).
