Order Service: Business & Technical Overview

Service Overview

The Order Service is the primary orchestrator of the OtelContext e-commerce ecosystem. It manages the entire lifecycle of a customer order, from initial placement to successful fulfillment and notification.

Core Functionality

• State Management: Tracks order status (Pending, Paid, Shipped, Cancelled).
• Service Integration: Acts as the central hub for the "Happy Path" simulation.

Technical Specifications

• Primary Port: 9001
• Technology Stack: Golang with OpenTelemetry (OTLP) instrumentation.
