Fix ECR Image Scan Gate Failures in GitLab CI Pipelines
ECR image scan GitLab CI gates fail silently in three distinct ways. Here's how to diagnose each failure mode and wire a hard gate that actually blocks deploys.
AWS Step Functions Lambda S3: 3 Production Mistakes We Made
We wired Step Functions into our Lambda S3 pipeline and hit silent timeouts, payload crashes, and a wildcard IAM role we ignored for months. Here's what we got wrong.
AWS Config CI Compliance Gate: Config Rules vs cfn-guard
Your Terraform apply passes but an unencrypted S3 bucket ships to prod anyway. Here's how to pick the right AWS Config CI compliance gate strategy.
How to Fail CI Pipelines on AWS Config NON_COMPLIANT Resources
AWS Config CI pipeline gate that catches NON_COMPLIANT resources before they stay in production — poll compliance after Terraform apply and fail fast.
How to Query ALB Access Logs with Amazon Athena for Incident Triage
Query ALB logs in Athena directly from S3 during live incidents. No ETL, no SSH grep sessions — just SQL against the exact 29-column schema.
S3 Presigned URLs: Expiration Strategy and Signing Identity Controls
Most teams treat S3 presigned URLs like short-lived tokens. They're not — the signing identity determines everything, and a misconfigured one turns a "temporary" URL into a persistent credential you can't revoke without breaking things.
AWS DataSync Task Failures: Finding the Error the Console Hides
DataSync tasks fail silently more often than AWS lets on. Here's the exact runbook — symptoms, root causes, and three fixes — to recover a broken transfer and prevent it from happening again.
S3 Lifecycle Governance for Logs, Backups, and Compliance Data
Uncontrolled object accumulation across S3 prefixes quietly inflates storage costs and complicates compliance audits. This tutorial walks through designing, applying, and verifying a multi-rule lifecycle configuration that covers log tiering, backup archival, and regulatory retention in a single policy document.
AWS Cost Anomaly Detection with Tag-Based Routing and Lambda Enrichment
Default AWS billing alerts tell you that spending is up — they rarely tell you why, or who owns the problem. This post walks through a production-ready pattern that combines Cost Anomaly Detection, SNS routing, and a Lambda enrichment layer to deliver alerts that include the responsible team, environment, and root cause service.
RDS Backup Validation and Automated Restore Testing on AWS
Automated RDS snapshot restores give you a repeatable, auditable process for verifying that your database backups are actually recoverable — before an incident forces you to find out otherwise. This post walks through the full pipeline: environment setup, CLI and Terraform configuration, end-to-end validation scripting, and the failure modes that quietly break restore workflows in production.
