Comparison of a FaaS- and SaaS-Based ETL Process in a Cloud Environment

The goal of this paper is to analyze experiences from a FaaS-based (function as a service) cloud-native implementation of an ETL process (extract, transform, load) based on AWS Lambda functions. The actual implementation is outlined and the experiences from that implementation are evaluated. This results in an overview of pros and cons of a cloud-native implementation in general and determines best practices for other implementations in other cloud environments or business domains.
