AWS Cloud Services

What You Will Have Built

Over five labs, you will progress from installing LocalStack for the first time to writing production‑quality Infrastructure as Code. You will look back at the journey through the lens of the skills you will have acquired.

In Lab 00 you will discover that the entire AWS API surface can be emulated locally, and that awslocal will communicate with LocalStack exactly as aws communicates with real AWS. That foundational understanding will enable every subsequent lab.

In Lab 01 you will build a complete IAM structure — users, groups, custom policies scoped to specific resources, and a service role with temporary credentials. You will understand why the principle of least privilege matters, how trust policies control role assumption, and why access keys are inferior to roles for application workloads.

In Lab 02 you will build you will go deep on S3 — the flat namespace model, versioning and delete markers, bucket policies versus identity policies, lifecycle rules for automated cost control, and static website hosting. You will understand why S3 is involved in more breaches than any other AWS service, and you will know the configurations that prevent that.

In Lab 03 you will launch compute infrastructure — key pairs using public‑key cryptography, security groups as stateful virtual firewalls, EC2 instance profiles bridging compute to identity, and user data scripts for bootstrapping. You will understand the instance lifecycle and why terminated instances cannot be recovered.

In Lab 04 you will build an event‑driven messaging pipeline — SQS standard and FIFO queues, visibility timeouts and dead-letter queues, SNS pub/sub topics, subscription filter policies, and the fan‑out pattern that will decouple producers from consumers. You will understand the architectural problem that messaging solves and the operational practices that will keep it running reliably.

And in Lab 05 you will express all of it as Infrastructure as Code — a version‑controllable, repeatable, reviewable specification of your entire infrastructure that will deploy in one command and will clean up in one command. You will understand the declarative model, intrinsic functions, change sets, and deletion policies.

This will form the foundation of professional cloud engineering. The specific services will evolve, but the principles — least privilege, loose coupling, declarative infrastructure, defense in depth — will remain durable. They will apply whether you are working with AWS, Azure, or GCP, whether you are using CloudFormation, Terraform, or Pulumi, and whether you are deploying to LocalStack on a laptop or to a multi‑region production environment serving millions of users.
