1	# AWS Cost Optimization
2
3	Apply practical FinOps controls to reduce AWS spend without sacrificing reliability or performance.
4
5	## When to Use This Skill
6
7	- Monthly AWS bill spikes unexpectedly or exceeds budget thresholds
8	- Preparing cost reviews with engineering and finance teams
9	- Rightsizing EC2, RDS, EKS, or Lambda workloads after load testing
10	- Choosing between Savings Plans, Reserved Instances, or on-demand pricing
11	- Setting up automated budget alerts and anomaly detection
12	- Cleaning up unused resources (unattached EBS, idle load balancers, old snapshots)
13	- Optimizing data transfer costs across regions and AZs
14
15	## Prerequisites
16
17	- AWS CLI v2 installed and configured (`aws configure`)
18	- IAM permissions: `ce:`, `budgets:`, `ec2:Describe*`, `cloudwatch:PutMetricAlarm`, `s3:PutLifecycleConfiguration`
19	- Cost Explorer enabled in the AWS billing console (takes 24 hours to populate)
20	- Cost allocation tags activated in the Billing console
21
22	## Cost Review Workflow
23
24	1. Tag every resource by team, service, environment, and cost center.
25	2. Enable Cost Explorer and activate Cost and Usage Reports (CUR) to S3.
26	3. Identify top spend drivers by service, account, and tag.
27	4. Rightsize underutilized compute and storage based on CloudWatch metrics.
28	5. Apply commitment discounts (Savings Plans or RIs) for stable baseline usage.
29	6. Set budgets, anomaly alerts, and build KPI dashboards.
30	7. Review monthly and iterate.
31
32	## Cost Explorer CLI Commands
33
34	```bash
35	# Get cost and usage for the last 30 days grouped by service
