Serverless Applications: Why, When, and How?
This addresses the problem of scattered and conflicting reports on serverless applications for companies and developers, though it is incremental as it builds on existing data.
The paper tackled the lack of systematic understanding of serverless computing adoption, suitability, and implementation by analyzing 89 serverless applications from diverse sources, making it the most extensive study to date.
Serverless computing shows good promise for efficiency and ease-of-use. Yet, there are only a few, scattered and sometimes conflicting reports on questions such as 'Why do so many companies adopt serverless?', 'When are serverless applications well suited?', and 'How are serverless applications currently implemented?' To address these questions, we analyze 89 serverless applications from open-source projects, industrial sources, academic literature, and scientific computing - the most extensive study to date.
