- Stop guessing capacity by scaling up or down as demand changes.
- Go global quickly by deploying resources in AWS Regions around the world.
Design Principles
- Design for failure and use multiple Availability Zones where resilience matters.
- Use managed services to reduce undifferentiated operational work.
- Automate wherever practical to reduce manual errors.
- Use elasticity and right-sizing to avoid idle capacity.
- Measure workloads with metrics and logs before optimizing.
Well Architected
- Operational Excellence: run and monitor systems effectively.
- Security: protect data, systems, and assets.
- Reliability: recover from disruptions and meet demand.
- Performance Efficiency: use computing resources efficiently.
- Cost Optimization: avoid unnecessary cost.
- Sustainability: reduce environmental impact through efficient design.
