This paper presents the experience of the authors in their efforts to apply an innovative computation paradigm – “serverless” computing – into managing cyber education environments through the Course Manager platform, developed by the authors’ team. The serverless paradigm, also referred to as Function-as-a-Service (FaaS), helps the developers abstract or automate away almost all infrastructure and operation overhead, allowing for what is often touted as "infinite scaling" applications, which can be a good fit for the rapidly increasing demand for practical cyber environments.

The authors provide an in-depth overview of the architecture and frontend of a cyber education environment management framework, designed to work in a serverless environment, and analyse the lessons learnt from using that framework in providing cyber trainings to students and IT professionals for more than a year.

This paper is included in the program of DIGILIENCE 2019 and will be published in the post-conference volume.
