1, 2, 3 Quarkus!
summary
Demonstrates building an Instagram-like stack with Quarkus 3.x: a REST upload service, an AWS Lambda image-resizer deployed with SnapStart to reduce cold starts, Kafka for events, Postgres for storage, and a native “wall” service on a small EC2 instance. Shows Quarkus dev mode auto-starting dependent containers, Spring-compatible annotations, passwordless WebAuthn, service discovery plus retries/timeouts, and measurements reporting sub-second startup and memory footprints around ~70MB native and ~150–200MB on the JVM using Quarkus 3.x extensions.
