Traditional broadcast infrastructures had to be built with on-premises architectures to provide five nines of reliability and to ensure the quality of service expected by premium content owners. However, robust live linear streaming services built on AWS are now feasible and in fact can be 100% available. Learn how broadcast media workflows with Elemental Cloud can provide ingest of heterogeneous video sources, fault tolerance across multiple Availability Zones, time synchronization of video streams, and sustained peak workloads in 24/7 applications.
