Pub/Sub vs REST API

Developers should learn Pub/Sub when building systems that require loose coupling, scalability, and real-time event handling, such as microservices architectures, IoT applications, or data streaming platforms meets developers should learn rest apis when building web services, mobile backends, or integrating systems, as they provide a standardized way to expose data and functionality over http. Here's our take.

Pub/Sub

Nice Pick

Developers should learn Pub/Sub when building systems that require loose coupling, scalability, and real-time event handling, such as microservices architectures, IoT applications, or data streaming platforms

Pros

• It is particularly useful for scenarios where multiple components need to react to events independently, like notifications, logging, or data processing pipelines, as it reduces dependencies and improves fault tolerance
• Related to: message-queues, event-driven-architecture

Cons

• Specific tradeoffs depend on your use case

REST API

Developers should learn REST APIs when building web services, mobile backends, or integrating systems, as they provide a standardized way to expose data and functionality over HTTP

Pros

• They are essential for creating scalable and maintainable applications, especially in microservices architectures or when developing public-facing APIs for third-party use
• Related to: http-protocols, json

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Pub/Sub if: You want it is particularly useful for scenarios where multiple components need to react to events independently, like notifications, logging, or data processing pipelines, as it reduces dependencies and improves fault tolerance and can live with specific tradeoffs depend on your use case.

Use REST API if: You prioritize they are essential for creating scalable and maintainable applications, especially in microservices architectures or when developing public-facing apis for third-party use over what Pub/Sub offers.

The Bottom Line

Pub/Sub wins

Developers should learn Pub/Sub when building systems that require loose coupling, scalability, and real-time event handling, such as microservices architectures, IoT applications, or data streaming platforms
