Multi-Cloud Video Pipeline: Active-Active Under 100ms

Designing an active-active video processing pipeline across AWS Elemental MediaLive and Azure Media Services — while hitting sub-100ms end-to-end latency — is exactly the kind of system design question that separates senior candidates from the rest.

You'll learn:

• How to architect an active-active topology spanning AWS and Azure without a single-cloud bottleneck
• State synchronization patterns for keeping MediaLive and Azure Media Services in lockstep during failover
• Where latency actually gets eaten in a multi-cloud video pipeline and how to budget your 100ms budget across encode, transit, and egress
• Trade-offs between consistency and availability when both clouds are simultaneously serving live streams
