## Principy

- **Dostupnost** — SLA, redundance, failover, multi-AZ/region
- **Škálovatelnost** — horizontalní vs. vertikální, auto-scaling
- **Bezpečnost** — defense in depth, least privilege, zero trust
- **Náklady** — FinOps, right-sizing, reserved instances
- **Operability** — observabilita, automation, dokumentace
