Product and engineering notes on cloud cost and carbon optimization.

The complete 28-slide deck on where AWS budgets actually go — the 27–32% waste problem, the four highest-impact savings categories, and a real account's $7.8K → $4.6K/month drop — embedded to read or download as a PDF.
October 14, 2026
The full GreenOps talk on YouTube: why every AWS account accumulates invisible waste, the four categories where the money goes, and a real account's drop from $7.8K to $4.6K/month.

CI/CD pipelines push a new container image on every build and almost nobody deletes the old ones. AWS flags missing ECR lifecycle policies as a cost-optimization check — here's how to audit and fix it.
October 9, 2026
July 2026's viral Cost Explorer bug showed some accounts trillion-dollar forecasts due to a unit-pricing error — and some teams panic-deleted production resources over a number that was never real. Why every team needs a second, independently-computed cost number that doesn't share a pipeline with AWS's own dashboard.

Multi-AZ RDS replication, cross-zone load balancing, and AZ-spread EKS/ECS workloads all generate cross-AZ data transfer costs — billed at ~$0.01/GB each way and folded invisibly into whichever service caused it. Detected with zero new IAM permissions.
September 19, 2026
CloudWatch bills on six meters at once, and its defaults compound forever: log groups with no retention, $0.50/GB ingestion, per-dimension custom metrics, and the GetMetricData polling tax behind third-party monitoring bills.
September 18, 2026
A missing free Gateway VPC Endpoint silently routes S3/DynamoDB traffic through your NAT Gateway at $0.045/GB — the well-known "$1,000 AWS mistake," and why it's worth checking even in accounts that fixed it once already.
September 17, 2026
GreenOps Scan now attaches each flagged resource's AWS tags — Project, Environment, Team, even the exact CloudFormation stack and logical ID — straight into every finding, no new IAM permissions required.
September 16, 2026
GreenOps Scan's new --llm-prompts flag turns every finding into a copy/paste prompt for Copilot, Claude, or Cursor to fix in your actual Terraform/CDK/CloudFormation source — no more IaC drift from hand-run remediation commands.
September 16, 2026
Every AWS region ranked by grid carbon intensity — a 105× spread between the dirtiest and cleanest, and why region choice beats every other efficiency lever, including Graviton.
September 15, 2026
GreenOps Scan now proactively detects deprecated Lambda runtimes, RDS/Aurora/DocumentDB engines, EKS versions, ElastiCache Redis, and OpenSearch domains before AWS starts billing you extra for staying on them.
August 28, 2026
A practical guide to collecting CPU, memory, and network baselines, matching the right instance family, and avoiding the common mistakes that kill Graviton migrations.
August 27, 2026
How to find S3 buckets that are bleeding money in Standard storage, old versions, and incomplete multipart uploads — and how lifecycle policies fix it automatically.
August 26, 2026
A non-technical guide for FinOps teams on why every month of delayed AWS waste review is money that cannot be recovered.
August 25, 2026
Run the free GreenOps Scan CLI as a Docker container — no Node.js install, no local dependencies, just pull, mount your AWS credentials, and scan.
August 25, 2026
A practical guide to finding and cleaning up unattached EBS volumes and old snapshots that keep billing you after the resource is gone.
August 24, 2026
A practical RDS cost audit: idle instances, oversized families, unused read replicas, stale snapshots, and missing reserved capacity — with the CloudWatch signals to check for each.
August 22, 2026
Two real greenops-scan reports, eight weeks apart, on the same AWS account: 53 flagged findings down to 1, and what AWS's own Cost Explorer forecast says next.
August 21, 2026
How GreenOps Scan finds idle Provisioned Throughput, orphaned custom models, and stale agents/knowledge bases in Amazon Bedrock — and prices the waste honestly.
August 19, 2026
GreenOps Scan's source isn't public, but its published package and runtime behavior are independently verifiable — see what Snyk and Socket.dev say, and why that matters more than reading the code.
August 13, 2026
Use the AWS CLI to create a dedicated ReadOnlyAccess IAM profile so GreenOps Scan (or any inspection tool) can never modify your AWS account.
August 11, 2026
How GreenOps complements Trusted Advisor, Cost Explorer, Compute Optimizer, and the Customer Carbon Footprint Tool.
August 7, 2026
How to detect over-provisioned ECS/Fargate services and right-size them to actual load.
July 13, 2026
How one read-only local command can surface potential AWS cost and carbon waste.
