- promise of availability

- 99% ~ 99.999%

- Free services don't have a SLA

- Broken SLA -> credit return (discount)

2) Composite SLA

- combined SLA of all components in your apps

Lower your SLA	Raise your SLA
Adding more services	Adding redundancy
Free/preview services	Service configuration (Availability zones)
Different services/tiers (Higher tier -> better SLA)
