AWS - FinOps and Cost Optimization

Explore how the cloud delivers cost savings, agility, and reach with pay for what you use pricing. See how rightsizing, elasticity, and spot options optimize costs and speed to market.

Empower doers and FinOps teams to drive cost efficiency and proactive optimization. Centralize rate reductions and governance while enabling appropriately sized instances and cost avoidance in engineering and operations.

Start small with immediate priority items when building your tagging strategy, and iterate to unlock value quickly. Define needs and ownership, set scope, decide mandatory vs discretionary, and secure buy-in.

Use a tag schema to enable measurement and cost attribution. Track tagged versus untagged usage in Cost Explorer and the AWS Cost and Usage report to drive compliance and optimization.

Activate and manage cost allocation tags in AWS billing to improve cost visibility, using user defined and AWS generated tags, and employing tag editor for bulk tagging.

Explore Cost Explorer, AWS's free visualization tool for cost and usage trends. It offers 14 months daily granularity and 38 months monthly granularity with resource-level detail.

Explore cost explorer in the AWS billing and cost management console to save custom reports, filter by service and dimension, and visualize and download cost data with forecasts.

Choose a centralized or decentralized AWS commitment strategy and apply savings plans and Ris to workloads for discounts. Track coverage, utilization, term options, and sharing to optimize discounts and reporting.

Savings plans are AWS billing commitments offering discounts for 1–3 year terms with upfront payment choices. Compute savings plans cover EC2, Fargate, and Lambda, optimize automatically across regions.

Discover AWS cost optimization hub, a free, one-stop tool that aggregates recommendations from trusted advisor, compute optimizer, savings plans, and RI recommendations across regions and accounts.

Learn to use AWS data exports to create customized CUR exports with selected columns, enable QuickSight dashboards inside the tool, and leverage CUR 2.0 account names for granular cost analysis.

Learn to enable cost anomaly detection in the AWS billing console, create monitors across services or by category, set alerts and thresholds, and analyze root causes via Cost Explorer.

Design automatable, fully loaded unit cost and unit economics metrics—like dollar per normalized hour or per gigabyte—that reflect storage, transfer, and requests while avoiding goodhart's law.

Analyze pricing factors and identify idle resources in time and usage billing; apply scheduling, commitments, tiered pricing, right-sizing, and evaluate serverless versus managed options using metrics to drive cost optimization.

Explore how to cut S3 costs by classifying data with storage tiers, identifying idle and transient buckets, and applying lifecycle policies and intelligent-tiering with Storage Lens insights.

Optimize rds costs by applying Trusted Advisor idle checks, using instance scheduler, and leveraging ris or graviton options, while right-sizing with CloudWatch and adding read replicas for heavy reads.

Explore practical Lambda cost optimization strategies, including Graviton/ARM upgrades, tiered pricing, savings plans, and right-sizing with Compute Optimizer, plus Trusted Advisor checks and power tuning.

Enable cost explorer with 38 month visibility and 14 day granularity, enable cost anomaly detection, and opt in to compute optimizer and cost optimization hub for proactive cost control.

Automate optimization by detecting, reporting, and remediating cost inefficiencies, reducing manual errors and overruns while leveraging native and third-party tools to scale and sustain savings.

Stay current with the latest releases, news, and best practices in FinOps by following the cloud financial management blog, cost optimization playbooks, rss feeds, and events like Reinvent.

Create and run a policy to convert GP2 EBS volumes to GP3 with Cloud Custodian, treating policies as code and validating with dry runs and reports.

Install the organization-aware cloud custodian to manage multi-account, multi-region governance using an account YAML file, and run dry runs with region-specific policies for GP2 and GP3 volumes.
