We have very different business processes. Sometimes they are held once a month. Other times the traffic is unpredictable over time. The perfect solution for such cases is Serverless architecture. Thanks to this approach, we can optimize the cost of the process, as well as obtain high availability even when the traffic is unpredictable. In this session, I will show a few examples of how to design business processes using the Serverless approach. We will focus on serverless and managed services and how to connect Lambda, SQS, EventBridge, S3 Bucket, DynamoDB, etc. to build highly scalable and cost-optimized applications.
