What is a managed database and why should I use one?

Short answer

  1. A managed database is a database instance (PostgreSQL, MySQL, MongoDB etc.) fully managed by a cloud provider.
  2. The provider handles installation, configuration, backups, security patches and monitoring — with no manual intervention.
  3. You access the database through a standard connection string and focus on your application, not infrastructure.
  4. Typical monthly cost is 20–200 EUR/month, versus 5–15 hours/month spent on self-management.

What the standard / legislation says

  • SLA: managed providers typically guarantee 99.9%–99.99% uptime, with contractual penalties if not met.
  • GDPR: data stored in the EU must be processed on European servers — verify the provider's region.
  • ISO 27001 / SOC 2: security certifications are standard with enterprise managed providers.
  • Backup: the GDPR-recommended minimum is daily backup with 30-day retention for personal data.

Practical examples

  • Example 1: SaaS startup with 3 employees — using PostgreSQL managed at 29 EUR/month; saving 10 hours/month vs. self-hosted.
  • Example 2: e-commerce app with 50,000 products — managed MySQL with active read replica; zero downtime on Black Friday.
  • Example 3: fintech platform with GDPR data — managed in Frankfurt (EU-West), audit log enabled, SOC 2 certified.

Common mistakes

  • Mistake 1: not enabling automatic backup — 40% of startups lose data at the first incident if backup is manual.
  • Mistake 2: choosing a provider with US servers for GDPR data — legally risky for EU citizens.
  • Mistake 3: not checking the SLA — 99.9% uptime means 8.7 hours downtime/year; 99.99% means under 1 hour.
  • Mistake 4: taking the cheapest plan without a read replica — any heavy query blocks the production application.
