Interface migration of shell scripts to the AWS Cloud

The migration is necessary because onpremise servers will be decommissioned at the customer in the future. The previous direct data transfer from the host to the Linux via Connect:Direct is no longer possible in this form. IBM Sterling File Gateway is therefore used for data transfer between the host and the AWS Cloud. In the new infrastructure, there is also a strict separation between data storage and processing logic. The transfer files to be processed are stored in a S3 (simple service storage) bucket. Proccessing is done using an AWS Lambda function, which is triggered when a new file is getting uploaded to the S3 bucket. Then it calls the shell scripts in the EC2 instance and the data gets written to an oracle database.
