シームレスなライブストリーミング体験

A live streaming CDN distributes live media streams through a globally distributed edge network to minimize latency, reduce buffering, and maintain stream quality under high concurrency. Fastly’s live streaming CDN is built on a programmable edge platform that enables real-time content delivery, rapid cache invalidation, and fine-grained traffic control—making it well suited for large-scale live video and interactive media streaming use cases.

Fastly reduces latency by caching and delivering live video streams as close to viewers as possible using its global edge network. Features like real-time log streaming, instant configuration updates, and advanced request routing allow teams to optimize the media stream path dynamically, helping maintain consistent performance even during traffic spikes or breaking live events.

Fastly supports industry-standard live streaming protocols and formats, including HLS and DASH, as well as Low-Latency HLS (LL-HLS), Low-Latency DASH (LL-DASH), and HESP. This ensures compatibility across modern browsers, mobile devices, smart TVs, and OTT platforms while enabling ultra-low-latency delivery for interactive and real-time use cases.

With support for both traditional and low-latency streaming workflows, engineering teams can deliver broadcast-scale live media experiences without being locked into proprietary formats or rigid delivery architectures.

Fastly’s platform is designed to absorb sudden surges in demand common with live video CDN workloads, such as product launches, sports, or news events. With a highly scalable edge network and real-time observability, teams can monitor media streaming performance, mitigate origin overload, and respond instantly to changing traffic patterns. To protect origins, Fastly uses request collapsing, consolidating simultaneous requests for the same live segment into a single origin fetch and serving the response to all viewers.

For high-stakes broadcasts, teams can leverage Fastly Live Event Monitoring for white-glove support, Capacity Reservation to pre-allocate delivery capacity, and Media Shield to centralize and protect origin traffic. Combined with real-time observability, these capabilities ensure predictable performance at scale without compromising viewer experience.

Yes. Fastly integrates security directly into its edge platform to protect live streaming workflows from DDoS attacks, malicious bots, scraping, credential abuse, and unauthorized access.

Security capabilities include edge-based DDoS mitigation, bot detection and mitigation, rate limiting, IP and geo controls, and token-based authorization to validate viewers before delivering segments or manifests. Teams can enforce signed URLs, short-lived tokens, and custom access logic at the edge to prevent stream hijacking and content theft.

Because these controls run at the edge, protection is applied without adding latency to the live stream, ensuring performance and security operate together at broadcast scale.

Fastly’s programmable edge allows developers and engineers to customize request handling, caching logic, authentication, and headers for live streaming CDN workflows. This level of control enables teams to tailor live media delivery to specific application requirements, regional needs, or business rules—all without redeploying backend systems.

Fastly provides granular, real-time and historical metrics across the full delivery path, from edge to origin. Key metrics include request volume, latency, cache hit ratio, origin fetch performance, error rates, and status codes, giving teams deep visibility into live stream health and viewer experience.

Data is accessible through streaming logs, dashboards, and APIs, enabling integration with existing observability and analytics platforms. Teams can also configure alerts based on thresholds or anomalies to proactively respond to performance degradation, origin stress, or unexpected traffic patterns during live events.

Fastly is designed to integrate seamlessly into modern cloud-native and multi-CDN architectures. It works alongside origin servers, encoding pipelines, DRM providers, and analytics platforms to deliver live media efficiently while giving teams full control over performance, security, and cost.

With capabilities like Media Shield, teams can introduce an additional caching layer that centralizes and protects origin traffic, improves cache efficiency, and reduces origin egress costs. This architecture strengthens resilience while maintaining low latency and high availability.

The result is a flexible, programmable delivery layer that gives engineering teams precise control over performance, security, and cost across complex live streaming workflows.

Yes. Fastly’s live streaming CDN is built for enterprises that require high availability, low latency, and operational transparency. It’s used by organizations delivering business-critical live video and media streams where reliability, performance, and real-time control are non-negotiable.

For high-profile or large-scale broadcasts, teams can leverage Fastly Live Event Monitoring for proactive monitoring and white-glove operational support before and during events. Combined with Fastly’s programmable edge and real-time observability, this ensures predictable performance and rapid response when it matters most.
