Provision real cloud resources with Terraform — a VPC, an S3 bucket, and an EC2 instance — using the standard init/plan/apply workflow.
A working mental model for AWS VPCs — what each piece does, how they connect, and why "VPC" is the wrong mental model if you came from physical networks.
Create your first S3 bucket, upload and download files, and set up the right access controls — without accidentally making everything public.
Write, package, and deploy a Lambda function using only the AWS CLI. Trigger it via a public URL. Understand what serverless actually means.
We deployed the same edge function on both platforms and measured for a quarter. Where each wins, where each loses, and the surprises along the way.
We ran Pulumi in TypeScript and Terraform in HCL side by side across 60+ services. Each won different categories of work. Here's the breakdown.
We moved a 60-node production EKS cluster to Auto Mode. Some pain points evaporated, others got harder. The cost picture is more nuanced than the marketing suggests.
We replaced 14 long-lived IAM users with SSO + temporary credentials. The migration plan, the gotchas, and the policies we now enforce.
We had .env files in three repos, AWS keys in Slack DMs, and a postgres password etched into a Confluence page. Cleaning it up took a sprint and changed how we think about secrets.
Practical patterns for Terraform modules at scale: versioning, composition, testing, and avoiding the monolith trap.
A real cost audit uncovered idle load balancers, oversized RDS instances, and forgotten snapshots. Here's what we found and how we fixed each one.
A hands-on RDS restore drill guide for small cloud teams that thought backups were covered until a timed restore test exposed missing steps, DNS confusion, and stale credentials.
