  • 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.
