With this blog post, you’ll learn how to use the Serverless framework to develop AWS Lambda functions using Java and Maven. To provide you with a realistic use case, we’ll develop an AWS Lambda that will generate a thumbnail for each new image that we upload to an S3 bucket. AWS Account Setup for Serverless
If your Spring application uses AWS components like S3, SNS, or SQS you might wonder how to write effective integration tests. Should I mock the entire interaction with AWS?
