Capstone: The Complete AWS Platform

A synthesizing capstone narrative covering a Spring Boot app on ECS Fargate behind an ALB, RDS and DynamoDB as dual data stores, S3 with event-driven file processing, SNS/SQS wiring services together, CloudWatch/X-Ray for observability, and a CI/CD pipeline deploying the whole system as one coherent architecture.

🎓 Learning objectives

  • •Describe, end to end, how a containerized application, two different databases, object storage, and messaging combine into one coherent production architecture
  • •Explain why a platform uses both a relational store (RDS) and a non-relational store (DynamoDB) for different parts of the same system rather than picking just one
  • •Trace a single user request and a single asynchronous event all the way through the full architecture
  • •Reason about where observability (CloudWatch, X-Ray) and CI/CD fit into an already-running distributed system
  • •Identify the failure domains and blast radius of each component in the platform
  • •Defend specific architectural choices in an interview setting as deliberate tradeoffs, not defaults
