How to Deliver an SRT Stream to 1000 Viewers with HLS and CloudFront
More live video workflow notes and product updates.
If you already have an SRT feed and the next requirement is viewer scale, the clean architecture is usually simple: ingest the SRT stream, create an HLS playback origin, and place CloudFront in front of that origin for delivery.
This page is the entry point for that route. It is not about using SRT as a public playback protocol for thousands of viewers. It is about using SRT for contribution, HLS for broad playback compatibility, and CloudFront for distribution at viewer scale.
The three steps are:
- ingest the SRT stream through a gateway
- create an HLS playback origin
- scale delivery with CloudFront
If you need the detailed first step, use SRT gateway setup. If you want the deep CDN configuration path, continue with CloudFront setup on AWS.
Why this architecture works
SRT is strong on the contribution side because it handles unreliable networks better than older ingest approaches. HLS is strong on the playback side because it works across a broad viewer device matrix. CloudFront is the scaling layer that helps distribute that playback path to a much larger audience.
Each part solves a different problem:
- SRT solves ingest resilience
- HLS solves viewer playback compatibility
- CloudFront solves distribution and geographic scale
Step 1. Ingest the SRT stream
The source should first land in a controlled SRT gateway or server rather than jumping directly into a public viewer stack. This keeps the contribution path stable and gives you a clean origin for the next stage.
Step 2. Create an HLS playback origin
Once the SRT feed is inside the platform, the next job is to expose it as HLS. That HLS output becomes the origin side that CloudFront can pull from.
Step 3. Scale delivery with CloudFront
After the HLS path exists, CloudFront becomes the delivery layer for the viewers. This is the point where the workflow stops being just an ingest chain and becomes a large-audience delivery architecture.
Where teams usually get into trouble
- trying to use SRT itself as the viewer protocol for broad public playback
- skipping origin validation and going straight to CDN setup
- treating CloudFront as if it fixes ingest instability
- ignoring HLS cache behavior and fragment rules

Final practical rule
When you need to move from one SRT source to many viewers, separate the jobs cleanly: SRT for ingest, HLS for origin playback, CloudFront for scale. That division is what keeps the architecture understandable and stable as the audience grows.
