Self-hosted vs. Managed Databases

Wann rohes Compute Managed-Komfort schlägt - und was Ownership wirklich kostet.

Zusammenfassung & Schnelle Antwort

Managed-Datenbankdienste verkaufen Komfort zum Mehrfachen der reinen Compute-Kosten. PostgreSQL oder MySQL selbst auf einem passend dimensionierten Cloud-Server zu hosten, holt die Marge gegen operative Verantwortung zurück.

The managed markup

A managed instance with the same vCPU and RAM as a commodity VM routinely costs 2-4x more once storage, backups, and high availability are itemized. The premium purchases automation, not hardware.

What self-hosting really requires

You own provisioning, monitoring, backup verification, failover drills, and security patching. Automated WAL archiving to object storage plus tested restores cover most small-team risk profiles.

RAM is the database spec that matters

Database performance tracks the working set held in memory. Size RAM generously before adding vCPUs; memory-optimized instances are usually the better spend.

A middle path

Many teams self-host primary databases on NVMe-backed VPS providers and keep managed services for exotic needs (global replication, serverless scaling). Compare both options against actual requirements rather than defaults.

Kernpunkte

  • Managed databases commonly cost 2-4x equivalent raw compute.
  • Self-hosting trades money for operational responsibility.
  • Prioritize RAM and NVMe when sizing database servers.
