low impact Delete idle resources right-size ec2 instances and launch configurations buy RIs improve autoscaling automatically shutdown unused resources implement cost-aware architectures use serverless
Provide motivation
- executive support and consistent communications
- single threaded authority for optimization
- training/tools
- time given to engineers to optimize
- provide dashboards to see the progress
- weekly or monthly canence that includes review of spend
Tools for right sizing
- computer optimizer
- cost explorer resource optimizier
- truster advisor (average is 10% or less over the last 14 days) (5MB or less on more than 4 or less days)
- trusted advisor may not be the best toll as it doesnt consider network io and doesnt look at committed RI instances
turn off resources outside of work hours look at AWS Instance Scheduler, uses tagging to shutdown your resources
- set ASGs to min size of 0
Unattached Elastic IPs Unattache EBS Idle or unattached load balancers incomplete s3 transfers clearing old snapshots
