The Gold Standard for modern cloud-native applications is a serverless architecture. AWS Lambda allows you to implement scalable and fault tolerant applications without the need of a single virtual machine.
A serverless infrastructure based on AWS Lambda has two key benefits:
- You don’t need to manage a fleet of virtual machines anymore.
- Deploying new versions of your code can be entirely controlled by API calls.
This article shows you how to process asynchronous tasks serverless. Possible use cases are: sending out massive amounts of emails, transcoding video files after upload, or analyzing user behavior. An SQS queue will be used to decouple your microservice from other parts of your system. You’ll learn how to implement the microservice with AWS Lambda.
