Pay TV operators are increasingly moving their existing traditional on-prem only infrastructure-based Multicast-assisted ABR (MABR) TV services to a new next generation distributed deployment architecture – a software defined, media optimized container applications based microservices deployed across multi-cloud (operators public cloud, operators edge cloud and operators on-prem private cloud) infrastructure. This paper explores the composition of such a multi-cloud-based deployment architecture and details software-defined service orchestration of such a distributed platform.
