In this talk, we will explore the evolution of streaming services developed and operated in-house by GRNET NOC, as influenced by the development of high quality open-source software and GRNET's cloud computing infrastructure. The technical discussion will be accompanied by observations on the increasing user demand for such services in recent years, using the Hellenic Parliament Web TV as a case study. The presentation will showcase how such a flexible and scalable infrastructure has allowed our team to cope with record-breaking bursts of user demand, and how the continuous evolution of this infrastructure towards high quality and cost effective services can scale to meet the expectations of users.
