Live streaming servers
Live streaming delivers video in real time, so it must ingest the live feed, transcode it on the fly, and deliver it to viewers with low latency — close to real-time. It handles viewer spikes for events and cannot be redone if it fails, so reliability is critical. Well-connected, capable infrastructure handles ingest and transcoding; EU hosting keeps it sovereign.
Key points
- Live streaming delivers video in real time — ingest, transcode, and deliver on the fly.
- It ingests the live feed from the broadcaster and transcodes it as it flows.
- Latency matters: viewers want to be close to real-time, which protocols affect.
- Live events bring viewer spikes, and a live stream can't be redone if it fails.
- Well-connected infrastructure handles ingest and transcoding; EU hosting keeps it sovereign.
What does live streaming need?
Live streaming delivers video in real time as it happens, which makes it distinct from on-demand streaming: the video is ingested from the broadcaster, transcoded on the fly, and delivered to viewers continuously and promptly, all in real time. There is no pre-prepared file to serve; the stream flows from the source, through processing, to the viewers as the event occurs, so everything must happen live, with the infrastructure ingesting the incoming stream, transcoding it as it arrives, and delivering it to viewers who want to watch close to real-time. This real-time pipeline is what defines live streaming and shapes its infrastructure.
The real-time nature makes live streaming demanding in ways on-demand streaming is not: it must keep up with the live stream as it flows, transcode it without falling behind, deliver it with low latency, and do all this reliably, since a live stream cannot be redone. Like all video streaming, it is bandwidth-heavy and needs transcoding, but the real-time constraint adds the need to keep pace with the live feed and deliver promptly. This page focuses on live streaming; on-demand streaming and transcoding are covered on their own pages, while what follows attends to what streaming live specifically requires.
Ingest: receiving the live stream
Live streaming begins with ingest — receiving the live video stream from the broadcaster into the streaming infrastructure — which must accept the incoming stream reliably and in real time. The broadcaster sends the live feed to the streaming server using a streaming protocol, and the server must receive it as it arrives, continuously, without interruption, since any break in ingest breaks the live stream. This ingest is the entry point of the live pipeline, taking the broadcaster's feed and bringing it into the infrastructure for transcoding and delivery, and it must handle the incoming stream reliably as it flows.
Reliable ingest matters because everything downstream depends on the incoming stream arriving intact and continuously. The infrastructure receiving the stream must have the network connectivity and capacity to accept it without loss, and must handle it in real time as it comes, so that the live pipeline has a steady input. For streams with multiple broadcasters or inputs, the ingest handles each. We provide well-connected infrastructure to ingest live streams reliably — accepting the broadcaster's feed continuously and in real time, with the connectivity and capacity to take it without interruption — so that the live pipeline starts with a steady, reliable input, on which the transcoding and delivery downstream depend.
Real-time transcoding
Live streaming transcodes the incoming stream in real time, converting it into multiple bitrates for adaptive delivery as the stream flows, which is more demanding than transcoding a stored file because it must keep pace with the live feed. As with on-demand streaming, viewers benefit from adaptive bitrate streaming, where the video is available in several qualities and the viewer's player picks based on their connection; for live, this transcoding into multiple qualities happens on the fly, as the stream arrives, and it must keep up with real time — falling behind would delay or break the stream. This real-time transcoding is a compute-intensive part of live streaming.
Because it must keep pace with the live stream, real-time transcoding needs sufficient, responsive compute, often GPU-accelerated for the parallel work of video processing. Transcoding a live stream into multiple qualities in real time takes significant compute, and it cannot fall behind, so the infrastructure needs enough transcoding capacity to keep up, which GPU acceleration helps provide efficiently. For live streaming with multiple streams or high resolutions, the transcoding compute is substantial. We provide the compute real-time transcoding needs, including GPU acceleration, so that a live stream can be transcoded into the qualities adaptive delivery uses as it flows, keeping pace with real time — a demanding, necessary part of live streaming.
Latency: how close to real-time
A defining consideration for live streaming is latency — how far behind real-time the viewers are — because live content loses value the further it lags, and different uses need different latency. Standard adaptive streaming introduces some seconds of latency between the live event and the viewer; low-latency streaming techniques reduce this for cases where being closer to real-time matters; and for interactive uses needing near-instant delivery, other approaches give sub-second latency. The right latency depends on the use: a broadcast can tolerate some delay, while an interactive live experience needs much less.
Achieving lower latency involves the whole pipeline — ingest, transcoding, and delivery — being fast and using techniques suited to low latency, which places more demand on the infrastructure. Lower-latency live streaming requires the ingest, real-time transcoding, and delivery to add as little delay as possible, and using low-latency streaming techniques, which the infrastructure must support. The lower the target latency, the more demanding this is. We provide infrastructure suited to the latency a live stream needs — capable of the fast ingest, real-time transcoding, and prompt delivery that lower-latency live streaming requires — so that viewers can be as close to real-time as the use calls for, whether a broadcast tolerating some delay or an experience needing to be nearer live.
Delivering live streams to viewers
Delivering a live stream to many viewers, like on-demand streaming, commonly uses a content delivery network in front of the origin, adapted to the real-time nature of live. The origin produces the live stream's segments as they are transcoded, and a content delivery network distributes them to viewers, caching and serving them from locations near viewers, so that many viewers can watch without every stream coming from the origin. For live, this delivery must handle the stream in real time, distributing segments as they are produced, so viewers receive the live content promptly.
The origin infrastructure remains important as the source producing the live stream that the delivery network distributes, so it must be capable and well-connected. The origin ingests, transcodes, and produces the live stream's segments, which the delivery network then serves to viewers; so the origin must keep the real-time pipeline flowing and serve the delivery network reliably. We provide well-connected origin infrastructure for live streaming — ingesting, transcoding, and producing the live stream that a content delivery network distributes to viewers — so that the origin keeps the real-time pipeline flowing and the delivery to viewers is handled by the origin-and-CDN combination, adapted to live. The CDN is a complementary service working with the origin we host.
Handling live event spikes
Live streaming often faces sharp viewer spikes, because live events draw viewers to watch at the same time, sometimes in very large numbers, and handling these concurrent surges without the stream failing is critical. Unlike on-demand content watched at various times, a live event is watched live, so its viewers arrive together, and a popular event can bring a sudden, large concurrent audience, placing heavy simultaneous demand on delivery. Handling this means the delivery being able to absorb the spike of concurrent viewers, which the content delivery network largely does by distributing the load, backed by a capable origin.
Provisioning for live spikes means preparing for the peak concurrent audience an event may bring, not just typical load. The delivery network scales viewer delivery across its locations to absorb the surge; the origin must keep producing the stream reliably under the load; and preparing for known large events ensures capacity is ready. We provide origin infrastructure able to keep the live pipeline flowing under the load of a large event, working with a delivery network that scales viewer delivery, so that a live stream can serve the concurrent surge a popular event brings — because for live, the spike arrives all at once when the event happens, and the stream must hold up precisely then.
Reliability: live cannot be redone
Reliability is especially critical for live streaming, because a live stream cannot be redone — if it fails during a live event, that moment is lost, unlike on-demand content that can simply be watched later. A failure during a live broadcast means viewers miss the live event, which cannot be repeated, so the consequences of a failure are immediate and irreversible in a way they are not for on-demand streaming. This makes the reliability of the live pipeline — ingest, transcoding, and delivery all working throughout the event — a paramount concern, since there is no second chance for a live moment.
Achieving this reliability means dependable infrastructure throughout the live pipeline, with resilience where it matters, so the stream holds up through the event. Reliable hardware and connectivity for ingest, enough transcoding capacity to keep up without failing, and dependable delivery all contribute; and for important events, redundancy in the pipeline guards against a single failure interrupting the stream. We host live streaming on reliable infrastructure, with the resilience important live events warrant, so that the live pipeline keeps working through the event — because for live streaming, a failure at the wrong moment loses a live event that cannot be redone, making reliability during the event essential.
Sovereignty, and where VV Internet Hosting fits
Live streaming involves content and viewer data, including the personal data of European viewers, so where the infrastructure runs governs these, making sovereignty a consideration. VV Internet Hosting is incorporated in the Netherlands, within the EU, so live streaming infrastructure hosted with us runs under European jurisdiction and outside the direct reach of the US CLOUD Act, keeping the content and viewer data under European law. For live streaming serving European viewers, keeping the infrastructure in the EU keeps that data sovereign.
We host well-connected, dedicated infrastructure for live streaming: the connectivity and capacity to ingest live streams reliably, compute including GPU acceleration for real-time transcoding, capable origin infrastructure to produce the live stream a content delivery network distributes, and the reliability live events demand — in EU datacenters under European jurisdiction. This suits live streaming services that want capable, well-connected, sovereign origin and transcoding infrastructure they control. We are clear about our limits: we provide the origin, ingest, and transcoding infrastructure, while a content delivery network for viewer delivery is a distinct, complementary service working in front of the origin we host; and we are not a managed live-streaming platform. We are the dedicated, sovereign infrastructure for a live streaming service's origin, ingest, and transcoding — and if that fits your needs, we can host it well.

Questions
Live streaming, answered plainly
Common questions about hosting for Live streaming.
How is live streaming different from on-demand streaming?
Live streaming delivers video in real time as it happens — ingesting the feed from the broadcaster, transcoding it on the fly, and delivering it to viewers continuously, all live. There's no pre-prepared file; everything happens in real time, so the infrastructure must keep pace with the live feed, deliver with low latency, and be reliable, since a live stream can't be redone.
What is latency in live streaming, and why does it matter?
How far behind real-time the viewers are. Standard adaptive streaming adds some seconds of latency; low-latency techniques reduce it; interactive uses need sub-second delivery. Live content loses value the further it lags, and the right latency depends on the use — a broadcast tolerates some delay, an interactive experience needs much less. Lower latency demands more of the whole pipeline.
Why is reliability so critical for live streaming?
Because a live stream can't be redone — if it fails during an event, that moment is lost, unlike on-demand content that can be watched later. The consequences of a failure are immediate and irreversible, so the reliability of the whole live pipeline — ingest, transcoding, and delivery working throughout the event — is paramount, with redundancy for important events.
