API Gateway vs Lambda vs ALB: AWS API Architecture Explained for Product Teams M2E3

Your API architecture decisions become product decisions faster than most teams realize.

In Module 2, Episode 3 of AWS for Product Teams, we break down one of the most important architecture conversations in modern cloud systems:

When should you use API Gateway?
When is Lambda the right backend pattern?
What role does an Application Load Balancer (ALB) actually play?
And when should your architecture move from synchronous APIs to event-driven systems?

This episode is designed for both:
👤 Product Managers who need to understand long-term product tradeoffs
💻 Developers building scalable AWS-native architectures

🚀 What You’ll Learn
PM Perspective
Why APIs are product contracts, not just endpoints
How API decisions shape:
partner integrations
mobile experiences
scalability
roadmap flexibility
REST vs GraphQL as a consumer-fit decision, not a religious debate
Why poorly designed APIs become long-term technical debt
Developer Perspective
Building APIs with:
Amazon API Gateway
AWS Lambda
SQS
SNS
Route 53
Request validation and API keys
Usage plans and throttling
Synchronous vs asynchronous architecture patterns
Event-driven design using SQS + Lambda
Why decoupling changes what’s possible in your architecture
🔥 Core Takeaway

Your API is not a database view.
It is a long-term contract with every product consumer.

The teams that design APIs around consumers instead of internal schemas build products that scale cleanly for years.

The teams that don’t?
They retrofit under pressure later.

👉 Call To Action (CTA)

If you’re building products on AWS and want to understand the intersection of:

product strategy
cloud architecture
scalable system design
and real-world engineering tradeoffs
