(Internship / Master Thesis) Abstracting Proprietary Serverless Cloud Building Blocks for Easier Development and Compliance


ELCA is a dynamic, international team of engineers, business analysts, software architects, designers and consultants. With over 2000 specialists, ELCA is the largest IT service provider in Switzerland. 

Description of the Internship /Master Thesis: 

Desire for abstraction: Many cloud adopters chose a hybrid cloud and/or have regulatory requirements to limit the coupling to cloud providers (such as the rules of FINMA).


The Push to Serverless can be complex: Modern Cloud Practices prefer Serverless Features as they are easier to operate (the management of the service is automated) and you pay only for what you consume. However, it requires much more integration than regular development and integrating components increases development complexity.


What if we could design an application with cloud-provider agnostic building blocks and deploy it to various target clouds? And even to a local environment for simpler debugging and analysis?

In this internship, we would like to evaluate these questions.

In this role

  • Get an understanding of Serverless Technologies (Functions, Queues, DBs, Block Storage, …) in at least two target environments (E.g. AWS and on-premise on Openshift with Knative)?
  • Assemble and evaluate existing technologies as a base for the work. Candidate technologies include, Terraform, AWS CDK, Apache Camel, Serverless Framework (, …
  • Define how to describe an application in a cloud-agnostic way. Ideas: Internal DSLs (Domain Specific Language), hierarchical description of components in YAML (such as Terraform does it), a graphical DSL?
  • Write some sample applications with the approach
  • Experiment with mappings of the cloud-agnostic representation to different target environments. What is a good approach? Fully automated generation? Or is a manual writing of the different target environment configurations more promising (except maybe the Serverless Functions)?

What we offer

  • A dynamic work and collaborative environment with a highly motivated multi-cultural and multiples international sites team
  • Personal development through training and coaching
  • A flat hierarchy and a culture of collaboration across all disciplines
  • The chance to make a difference in peoples’ life by building innovative solutions
  • High innovation and research backed up by collaboration with universities like EPFL/ETH
  • Various internal coding events (Hackathon, Brownbags), see our technical blog
  • Monthly After-Works organized per locations
  • Good life balance (41 working hours per week and possibility to work 2 days per week from home)

About your profile

  • Interest for the cloud services on typical Hyperscaler/ On Premise cloud infrastructures
  • Interest in application architectures
  • Interest in comparing and applying different development approaches
