Overview

• When we start deploying multiple applications, they will inevitably need to communicate with one another

• There are two patterns of application communication

• Synchronous between applications can be problematic if there are sudden spikes of traffic

• What if you need to suddenly encode 1000 videos but usually it’s 10?

• In that case, it’s better to decouple your applications:

  • using SQS: queue model

  • using SNS: pub/sub model

  • using Kinesis: real-time data streaming model

• These services can scale independently from our application!
