From Serverful to Serverless: A Spectrum of Patterns for Hosting Application Components
Vladimir Yussupov, Jacopo Soldani, Uwe Breitenbücher, Antonio Brogi, Frank Leymann · 2021
The diversity of available cloud service models yields multiple hosting variants for application components. Moreover, the overall trend of reducing control over the infrastructure and scaling configuration makes it non-trivial to decide which hosting variant suits more a certain software component. In this work, we introduce a spectrum of component hosting patterns that covers various combinations of management responsibilities related to (i) the deployment stack required by a given component as well as (ii) required infrastructure resources and component’s scaling rules. We validate the presented patterns by identifying and showing at least three real world occurrences of each pattern following the well-known Rule of Three.
