Real World Example
Launch Day for ShopEase
This is how a small Indian D2C brand (think a startup selling on its own site, like boAt or Mamaearth did in their early days) launches a Spring Boot backend. Every module of this course shows up in the timeline.
| Time | What happens | Module |
|---|---|---|
| T-7 days | load test at 2× expected traffic, fix N+1 and pool size | Performance |
| T-3 days | dashboards and alerts live; payment health indicator added | Actuator and Monitoring |
| T-1 day | product cache warmed on ApplicationReadyEvent | Internals, Caching |
| T-0 09:00 | release v1.0.0 via GitHub Actions, rolling deploy | Packaging and Deployment |
| T-0 10:15 | orders flow: events trigger email/SMS on a bounded pool | Events, Async |
| T-0 14:00 | payment provider slow → alert fires, fallback gateway switched by property | Internals (@Conditional), AOP audit |
| T-0 23:30 | nightly report job runs once (ShedLock) | Scheduling |
Example
Status at the end of launch day:
curl -s localhost:8081/actuator/metrics/shopease.orders.placedExample output
{"name":"shopease.orders.placed","description":"Orders placed","measurements":[{"statistic":"COUNT","value":4817.0}],"availableTags":[{"tag":"channel","values":["web","app"]}]}Tip: Build this capstone yourself. Put it on GitHub with a README, the API table and a Grafana screenshot: it is a strong project to discuss in Java full stack interviews.
