Logistics & Transport Platform Architecture Overview

What is the core architecture of a Logistics & Transport Platform?

The core architecture of this Logistics & Transport Platform is a sophisticated, multi-tenant, event-driven microservices system. It is specifically designed to serve Senders, Receivers, and Carriers by exposing flexible REST and optional GraphQL APIs. This platform efficiently ingests real-time IoT telemetry data, which is then processed by a dedicated AI service. This AI service performs critical functions such as predicting Estimated Times of Arrival (ETA), detecting potential hazards, determining ideal transfer dates, and optimizing complex routes, ensuring intelligent and responsive logistics management.

What are the essential high-level components of this logistics platform?

The logistics platform is built upon a set of essential high-level components that collectively enable its comprehensive functionality and scalability. These components work in concert to manage client interactions, secure data flow, process information, and ensure operational efficiency. From external user interfaces to internal infrastructure, each part plays a vital role in supporting the platform's event-driven and microservices-based architecture, facilitating seamless logistics operations and data management across the ecosystem.

• Clients: Encompasses various user interfaces and external systems, including web and mobile applications for Senders, Receivers, and Carriers, facilitating direct interaction with the platform's services.
• API Gateway: Acts as the single entry point for all external requests, handling authentication, rate limiting, request routing, and TLS termination to ensure secure and efficient communication.
• Core Microservices: A collection of independent, specialized services, each responsible for a specific business capability (e.g., shipments, tracking, identity), enabling modularity, scalability, and resilience.
• AI Service: A dedicated component leveraging machine learning for advanced analytics, including Estimated Time of Arrival (ETA) predictions, hazard detection, optimal transfer date calculations, and sophisticated route optimization.
• IoT/Device Gateway: Securely ingests real-time telemetry data from various IoT devices and sensors deployed on vehicles or cargo, providing crucial data for tracking and monitoring.
• Event Bus: A central messaging backbone that enables asynchronous communication between microservices, facilitating event-driven architecture for loose coupling and real-time data propagation.
• Data Stores: Comprises various database technologies optimized for different data types, such as relational databases for transactional data, NoSQL for flexible schemas, and time-series databases for IoT telemetry.
• Observability: Tools and practices for monitoring, logging, tracing, and alerting across the entire platform, ensuring operational visibility, performance analysis, and rapid issue detection.
• Infra & CI/CD: The underlying infrastructure (cloud or on-premise) and Continuous Integration/Continuous Deployment pipelines that automate the building, testing, and deployment of all platform components.
• Edge/Device Fleet: Refers to the physical IoT devices, sensors, and potentially edge computing units deployed in the field, responsible for collecting and transmitting real-time operational data.

What core services define the platform's functionality and API interactions?

The platform's functionality is primarily driven by a suite of core microservices, each meticulously designed with specific responsibilities and a well-defined API surface. These services operate independently yet communicate seamlessly via the event bus, ensuring robust and scalable operations. They collectively manage everything from user authentication and shipment lifecycle to real-time tracking, route optimization, and financial transactions, providing a comprehensive solution for modern logistics challenges through structured API endpoints and event emissions.

• API Gateway: Manages JWT/OAuth2 validation, client authentication, rate-limiting, request routing, and TLS termination, ensuring secure and controlled access to internal services. It enforces Idempotency-Key on mutating POSTs.
• Identity & Access Service: Provides features for user sign-up/login, Single Sign-On (SSO), managing organizations/tenants, roles and permissions (RBAC), user management, and API key support.
• Shipments Service: Facilitates creating and updating shipments and items, generating Air Waybills (AWBs), managing status lifecycles, handling Proof of Delivery (POD), and supporting custom fields. It emits events like shipment.created.
• Tracking Service: Ingests telemetry data via HTTP/MQTT, maintains a device twin, performs geofence detection, provides last-known location, and manages route checkpoints. It stores data in a timeseries DB and emits telemetry.ingested events.
• Routing & Dispatch Service: Handles vehicle/driver assignment, route planning, integrates with VRP solvers, and supports re-optimization processes. It emits events such as route.created and assignment.created.
• Notifications Service: Utilizes a template engine to send notifications via SMS, Email, Push, and WhatsApp. It also dispatches signed webhooks and manages user/organization preferences with retry/backoff mechanisms.
• Documents & Compliance Service: Generates labels (PDF/ZPL), manifests, and customs documents. It performs Dangerous Goods (DG) validation and manages the upload/download of documents to an object store.
• Billing & Payments Service: Offers a pricing engine, generates quotes and invoices, integrates with various payment gateways, and manages refunds, streamlining financial aspects of logistics.
• Analytics & Reporting: Provides dashboards, tracks key performance indicators like On-Time In-Full (OTIF), generates SLA breach reports, supports data exports, and feeds data into data warehouses for business intelligence.
