Why reliability matters
Enterprise systems need observability, clear failure handling, and safe deployments.
Start with health checks
Expose health endpoints thoughtfully and secure sensitive actuator endpoints.
@RestController
class HealthExample {
@GetMapping("/api/ping")
public String ping() {
return "ok";
}
}Monitor your system
Track response latency, error rates, memory, and database connection pool usage.
Deploy safely
Use staging environments, test database migrations, and keep a rollback plan.
