Is a managed database worth the extra cost over self-hosted?
Managed databases cost 20-40% more than running your own on a VM, but include automated backups, patching, failover, and monitoring. For most teams the operational savings outweigh the price premium. Self-hosting makes sense only when you need custom configurations or have dedicated DBA expertise.
What is included in managed database hourly pricing?
