Drones and trucks sending telemetry
Cloud / Knowledge library
Amazon API Gateway
Creates and manages REST, HTTP, and WebSocket APIs at scale
Why learn Amazon API Gateway?
Teams use Amazon API Gateway to adopt API management without building the complete underlying platform themselves.
The problem it solves
Publishes, secures, transforms, monitors, and governs APIs
Where it came from
Amazon API Gateway is Amazon Web Services's offering for API management. Its closest catalog counterparts are Azure API Management and Google Cloud Apigee; they address the same broad need but are not feature-for-feature identical.

Real World Example
Unified Logistics API Gateway Integration
A regional logistics firm managing a fleet of delivery drones and ground vehicles that need to report telemetry data to a centralized tracking system.
The business problem
The firm struggles with fragmented endpoint management where disparate microservices for drone telemetry and truck location tracking lack a unified authentication layer, leading to security vulnerabilities and inconsistent data formatting.
How this topic solves it
Amazon API Gateway acts as a centralized front door for the logistics fleet, providing a single entry point that handles request routing, authentication, and protocol transformation for both REST and WebSocket traffic.
- Define a REST API resource structure that maps incoming telemetry requests to specific backend microservices.
- Configure an Authorizer to validate incoming tokens from drone and vehicle hardware before forwarding requests.
- Deploy a WebSocket API to enable bidirectional communication for real-time drone control commands.
- Implement request validation to ensure telemetry payloads conform to expected JSON schemas before reaching the backend.
- Enable stage-based deployment to manage different versions of the logistics API for testing and production environments.
Flow of telemetry data from fleet vehicles through the API Gateway to backend services.
Centralized routing and auth
REST backend for data storage
WebSocket backend for real-time control
- Fleet Devices → HTTPS/WSS Request → API Gateway
- API Gateway → REST Routing → Telemetry Service
- API Gateway → WebSocket Forwarding → Command Service
Expected business outcome
The logistics firm achieves a standardized, secure interface for all fleet communications, reducing the complexity of managing individual microservice endpoints while ensuring consistent security policies across the infrastructure.
Limitations and checks
API Gateway introduces a potential single point of failure and additional latency for every request; developers must monitor the CloudWatch metrics for 5XX errors and latency spikes to ensure the gateway is not bottlenecking traffic.
