Efficient Order Tracking Solution: Leveraging AWS Services for Seamless Operations
- S3
- CloudFront
- API Gateway
- Lambda
- RDS
01Problem
The challenge
A company needed a way for customers to check order status without emailing support for every update. The tracking page had to be hosted on S3 behind CloudFront, call a third-party order management API through API Gateway and Lambda for live order details, and authenticate each user against the company's own RDS database before showing anything.
02Architecture
How it fits together
03Solution
What I built
Build a tracking page on S3 and CloudFront, with API Gateway and Lambda handling order lookups and RDS handling authentication.
01
S3 + CloudFront
Tracking page
Static tracking page application hosted on S3 and delivered through CloudFront.
02
API Gateway
Secure API
Exposes the order tracking endpoints the frontend calls.
03
Lambda Integration
Order lookup
Lambda function fetches order details from the third-party order management API.
04
RDS Authentication
User auth
User details authenticated against AWS RDS before order data is returned.
04Outcomes
What it delivered
Scalability
S3, CloudFront and API Gateway absorb demand without capacity planning.
Secure authentication
RDS-backed auth ensures only authorized users see order data.
Cost-effectiveness
Pay-per-request pieces keep running cost proportional to actual use.
Customers now track their own orders without contacting support, and RDS-backed authentication keeps that data visible only to the account it belongs to.
