Episode 24: Infrastructure as Code & CI/CD: Automating Deployments on AWS | SAA-C03

🎁 Free SAA-C03 cheat sheet for this series - link at the bottom.

Master IaC & automation! CloudFormation, CDK, Beanstalk, SAM & the CodePipeline suite. Punchy 35-min format!

🆕 INTERACTIVE FORMAT

🎯 PULSE CHECKS - Real pauses to test yourself

⚠️ TRAP SPOTLIGHTS - Exam traps highlighted live

💡 MEMORY HOOKS - Vivid analogies that stick

🏗️ AWS CLOUDFORMATION (the star!)

• DECLARATIVE Infrastructure as Code (YAML/JSON)

• You declare WHAT you want; AWS handles the HOW

• Auto-handles resource ordering & dependencies

• Version-controlled, code-reviewed infrastructure

• Templates → Stacks → StackSets (multi-account/region)

• Service Role: deploy without direct resource permissions (needs iam:PassRole)

• Cost trick: auto-delete dev infra at 5PM, recreate at 8AM

Hook: Architect's blueprint handed to a construction crew.

💻 AWS CDK (Cloud Development Kit)

• Define infrastructure in a REAL language (Python, TypeScript, Java, .NET)

• Loops, variables, reusable components

• Compiles DOWN to CloudFormation

• Great for serverless & container teams

Hook: A design program that writes the blueprint for you.

🌱 ELASTIC BEANSTALK

• Platform-as-a-Service (PaaS)

• Hand over code; it manages EC2, ELB, ASG, scaling, monitoring

• You still keep full config control

• FREE (pay only for underlying resources)

• Web Server Tier (HTTP) vs Worker Tier (SQS-driven jobs)

• Single-instance (dev) vs High-Availability (prod)

• Uses CloudFormation underneath

Hook: A valet service for your application.

⚡ AWS SAM (Serverless Application Model)

• CloudFormation optimized for SERVERLESS

• Concise syntax for Lambda, API Gateway, DynamoDB

• Local build/test via SAM CLI

Hook: A specialized serverless blueprint kit.

🔄 CI/CD PIPELINE (the CodeSuite)

• Source control (Git) kicks off the pipeline

• CodeBuild: compiles code + runs tests (serverless)

• CodeDeploy: deploys to EC2/Lambda/ECS - owns blue/green & canary

• CodePipeline: orchestrates the whole flow

• Integrates with EventBridge (e.g. failed build → notification)

Hook: Factory assembly line - build station, shipping station, conveyor belt.

🔧 TWO EXTRAS

• App2Container: modernize legacy Java/.NET apps into containers

• Amplify: full-stack web/mobile apps with hosted backend

⚠️ TOP EXAM TRAPS

1. CloudFormation = declarative IaC (YAML/JSON)

2. CloudFormation (templates) vs CDK (programming language)

3. Beanstalk (PaaS, quick app deploy) vs CloudFormation (any infra)

4. Service Role = deploy without resource permissions (iam:PassRole)

5. SAM = CloudFormation for serverless + local testing

6. CodePipeline orchestrates, CodeBuild builds, CodeDeploy deploys

7. Blue/green & canary = CodeDeploy

8. Beanstalk Web tier (HTTP) vs Worker tier (SQS)

9. App2Container (legacy→containers) vs Amplify (full-stack apps)

10. StackSets = same stack across accounts/regions

📊 DECISION FRAMEWORK

• Repeatable infra as code? → CloudFormation

• Infra in a programming language? → CDK

• Quick app deploy, minimal management? → Beanstalk

• Serverless app? → SAM

• Automate the release pipeline? → CodePipeline + CodeBuild + CodeDeploy

• Multi-account/region stacks? → StackSets

🎧 Perfect for SAA-C03 prep! CloudFormation is heavily tested across domains.
