AdvancedMediumLesson 9 of 9
AWS Well-Architected Framework — six pillars: Operational excellence, Security, Reliability, Performance efficiency, Cost optimisation, Sustainability.
Cost levers: right-size instances (Compute Optimizer), Savings Plans/Reserved Instances for steady load, Spot instances for interruptible work, Graviton (ARM) instances for .NET (cheaper per performance), Lambda/Fargate for spiky workloads, S3 lifecycle to cheaper tiers, turn off non-prod at night, delete idle resources (unattached EBS, old snapshots, idle NAT gateways and load balancers), Budgets with alerts, cost allocation tags.
