Comparison &Adoption of FOSS Serverless Computing for Enterprise Openstack Cloud Platform

Abstract

Cloud Computing paradigm accelerated the phase of development & deployment of software applications over on-demand api-enabled programmable infrastructure. However, the decision factor of hosting the applications over On-Premises or Public Cloud generally dependent on the features of Cloud Service offerings like IaaS, PaaS, CaaS and SaaS from the respective Cloud Platforms. Pubic Clouds are always on top with their taxonomy of service offering list, this worries enterprise IT departments about future platform dependency and cost aspects, hence phenomenon of Open Source Cloud Computing platforms like Openstack [25] are encouraged by IT Enterprises to offer Cloud Services similar to Public Clouds. Serverless Computing is an emerging cloud service construct wherein software applications decompose into multiple independent stateless functions, which are run only when invoked or trigger by events and killed when functions session expired. There are multiple FOSS Serverless Computing frameworks available, comparison & adoption of suitable framework for Openstack based On-Premises Cloud platform with appropriate design and implementation procedure is the objective of this paper.
