This pattern shows you how to launch an AWS Lambda function that automatically converts mainframe EBCDIC (Extended Binary Coded Decimal Interchange Code) files to character-delimited ASCII (American Standard Code for Information Interchange) files. The Lambda function runs after the ASCII files are uploaded to an Amazon Simple Storage Service (Amazon S3) bucket. After the file conversion, you can read the ASCII files on x86-based workloads or load the files into modern databases.
