Incident Escalation Engine (DevOps-Focused Backend Project)

A DevOps-oriented backend system that simulates real-world incident escalation workflows used by SRE and reliability teams.

This project demonstrates the complete software delivery lifecycle:

• Backend system design (Spring Boot)
• Containerization (Docker)
• Automated CI/CD (GitHub Actions)
• Image Registry Integration (Docker Hub)
• Production-style deployment readiness

---

Project Overview

In large distributed systems, failures must be detected, tracked, and escalated automatically.

This application allows:

• Creating incidents with severity levels
• Automatic escalation simulation based on time gaps
• Acknowledgement handling
• Metrics dashboard for operational visibility

Tech Stack

Backend

• Java 21
• Spring Boot
• Spring Data JPA
• Lombok

Database

• PostgreSQL

DevOps / Infrastructure

• Docker
• Docker Compose
• GitHub Actions (CI/CD)
• Docker Hub (Container Registry)

Features

1. Incident Management

• Create incident with severity & trigger source
• Status lifecycle:

OPEN → NOTIFIED → ESCALATED → ACKNOWLEDGED

2. Escalation Simulation

Time-based escalation intervals:

Severity	Escalation Delay
HIGH	10 sec
MEDIUM	30 sec
LOW	60 sec

3. Metrics Dashboard

Operational metrics include:

• Open incidents count
• Acknowledged incidents count
• Average acknowledgement time
