Multimedia content delivery and real-time streaming over the top of the existing infrastructure is nowadays part and parcel of every media ecosystem, thanks to open standards and the adoption of the Hypertext Transfer Protocol (HTTP) as its primary mean for transportation. Hardware encoder manufacturers have adopted their product lines to support the dynamic adaptive streaming over HTTP but suffer from the inflexibility to provide scalability on demand, specifically for event-based live services that are only offered for a limited period of time. The cloud computing paradigm allows for this kind of flexibility and provides the necessary elasticity in order to easily scale with the demand required for such use case scenarios. In this talk we describe how to deploy transcoding and streaming-as-a-service platform based on open standards (i.e., mainly MPEG-DASH) utilizing standard cloud and content delivery infrastructures to enable low-delay and high-quality streaming to heterogeneous clients. We describe how to deploy it for video on demand, 24/7 live and event-based live services. The talk also provides comprehensive evaluation results both with regard to the transcoding/streaming and client adaptation behavior. It allows attendees to identify bottlenecks in their transcoding and streaming workflows and how to use public infrastructure components and MPEG-DASH to overcome existing limitations.
