Deep guides
Implementation detail with trade-offs and operational context.
Production-grade AWS and platform engineering notes
How production systems are actually designed, operated, and debugged.
InfraTales publishes deep technical guides, architecture teardowns, cost analyses, and failure-driven lessons for engineers and technical leaders building real systems on AWS.
Built for cloud architects, senior engineers, platform teams, and technical founders who need trade-offs, cost realities, and operational clarity instead of demo-level walkthroughs.

AWS CDK Transit Gateway Multi-Environment VPC: Dev, Staging, Prod on One TGW
Running dev, staging, and prod on separate VPCs sounds clean until you need them to talk — and your Aurora failover has never actually been tested. This post walks through a real CDK TypeScript stack wiring Transit Gateway, Aurora Global Database, ECS Fargate, and Global Accelerator across three env
AWS CDK Security as Code: VPC, IAM, KMS, WAF and Config in One Stack
Most AWS accounts get hardened once by someone who no longer works there. This post walks through a CDK TypeScript stack that encodes VPC isolation, KMS key policies, IAM least-privilege, AWS Config rules, WAF, and CloudTrail into version-controlled, PR-reviewable infrastructure — so your security p
AWS CDK S3 to Lambda via EventBridge: Full Cost and Architecture Breakdown
Most S3-to-Lambda setups skip CloudTrail data events entirely and pay for it later with brittle fan-out and zero audit trail. This post walks through a CDK TypeScript stack that routes S3 events through EventBridge properly — VPC placement, KMS encryption, Secrets Manager, cost model, and the failur
AWS CDK EC2 CodeDeploy Pipeline: ALB and Auto Scaling Without the 2am 502s
Wiring CodePipeline, CodeDeploy, and Auto Scaling in CDK sounds straightforward until your first real scale event cracks the deployment. This post walks the full architecture - VPC, ALB, ASG, SSM config, and the lifecycle hook settings that keep deploys clean under load.
AWS CDK Web App Deployment: VPC, Fargate, Aurora, and CloudFront Wired Together
Most CDK tutorials stop at 'it deployed.' This one covers the full aws cdk web application deployment stack - VPC isolation, Fargate on private subnets, Aurora with KMS, CloudFront, Secrets Manager rotation - and the six operational gaps that will wake you up at 2am if you skip them.
AWS CDK KMS Encryption with IAM Roles: One Stack for EC2, S3, and RDS
Your IAM permissions are a wiki page nobody trusts. This post walks through a CDK TypeScript stack that encodes KMS encryption, IAM roles, and RDS storage security as versioned, reviewable code - and covers the operational traps most tutorials skip entirely.
