16. Conclusion
• OF@TEIN proposed automation verified to
facilitate easy and fast experimentation
• By utilizing DevOps tools give possibility to
automate resources provisioning and experiment
execution
• By developing DevOps Tools more tasks and stages
can be covered in OF@TEIN lifecycle Experiment
