Serverless Developer Guide
Connecting services with events and event-driven architecture gives you a consistent and scalable 
way to build solutions with hundreds of services.
Summary
• Serverless is built on independent services that communicate through events in an event-driven 
architecture.
• event-driven architecture (EDA) - a modern architecture pattern built from small decoupled 
services that publish, consume, or route events.
• events - represent a change in state, or an update
• Decoupled microservice architecture helps you build modern, agile, and extendable applications 
faster than traditional monolithic applications, and free developers from needing to learn 
everything at once about existing systems.
