API Communication Styles | SOAP REST GraphQL gRPC | Use cases and Trade Offs | System Design

In this video, I break down the four major API communication styles used in modern system design: SOAP, REST, GraphQL, and gRPC.

We explore how each one works, why different styles exist, and when to use which—based on your app’s performance, flexibility, and scalability needs.

🧠 What You’ll Learn:

🔹 What is an API and why different communication styles exist
🔹 Deep dive into each API style:
 ▪ SOAP – XML-based, strict contracts, enterprise use
 ▪ REST – Resource-based, flexible, widely adopted
 ▪ GraphQL – Query-driven, efficient data fetching
 ▪ gRPC – Binary protocol, high-performance, ideal for microservices
This video will help you choose the right API style for your architecture based on trade-offs and design goals.
