A company is looking for an automated orchestration solution that will run a job once every day. Once triggered, the job searches for new data that is added to an Amazon S3 bucket and then performs an extract, transform, and load (ETL) sequence to transform the newly added data. The transformed data is saved back to another S3 bucket and then an AWS Lambda function is triggered to start the downstream process. Which AWS service/feature can be used to meet these requirements with the LEAST operational overhead?
