Learn¶

• What is cloud computing? - capex → opex is the FinOps premise
• Serverless explained - pay-per-use lever
• Regions and availability zones - region pricing matters

Compare¶

• Compute - the largest single cost line for most workloads
• Storage - tiering, lifecycle, egress
• Databases - managed DBs are cost-heavy; choosing right matters

Reference¶

• Cost optimization: AWS - RIs, Savings Plans, S3 tiering, EBS gp3, Compute Optimizer
• Cost optimization: Azure - Reserved Instances, Hybrid Benefit, Cost Management
• Cost optimization: GCP - committed use, sustained use, Recommender
• FinOps principles - the discipline itself
• Well-architected: AWS cost pillar, Azure, GCP
• Free tier guide - free credits and continuous-free services for study

Build¶

• Build infra with Terraform - tagged-from-day-one IaC is the FinOps default
• Set up a monitoring stack - cost dashboards alongside performance
