Function as a service (FaaS) is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage application functionalities without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Building an application following this model is one way of achieving a "server-less" architecture, and is typically used when building micro-services applications. FaaS is an extremely recent development in cloud computing, first made available to the world by hook.io in October 2014, followed by AWS Lambda, Google Cloud Functions, Microsoft AzureFunctions, and Oracle Cloud Fn in 2017 which are available for public use. FaaS capabilities also exist in private platforms, as demonstrated by Uber's Schemaless triggers. The project’s goal was to understand how OpenStack Qinling can help the HEP community developing/deploying applications/workload along with how this project can be integrated with CERN cloud infrastructure.
