CDN — Content Delivery Network

High-performance media delivery optimized for video streaming — HLS, MPEG-DASH, HDS, and pseudo-streaming.

What is a CDN and why do you need one?

A Content Delivery Network (CDN) is a distributed system of servers that delivers web content to users from the geographically closest location. For video streaming platforms, a CDN is essential because it reduces buffering, minimizes latency, and ensures smooth playback for viewers worldwide. Without a CDN, all traffic flows through your origin server — creating a single point of failure and a bottleneck that degrades the viewing experience as your audience grows. KVS Service designs and deploys custom CDN solutions tailored specifically for media-heavy workloads, ensuring that your content reaches viewers quickly and reliably regardless of their location.

How does the KVS Service CDN work?

Our CDN infrastructure is built on dedicated servers with high-bandwidth uplinks (1-10 Gbit/s per node) rather than shared multi-tenant platforms. This means your CDN nodes have guaranteed bandwidth and consistent performance — critical for video delivery where a single stream can consume 5-15 Mbps per viewer. We design CDN architectures with edge caching, origin shielding, and intelligent load balancing to optimize delivery for your specific content type and audience geography. Each CDN node runs on enterprise Dell or Fujitsu hardware in Tier III datacenters.

Which streaming protocols are supported?

KVS Service CDN supports all modern video streaming protocols used in production today:

• HLS (HTTP Live Streaming) — the most widely used adaptive bitrate streaming protocol, supported natively by iOS, macOS, Android, smart TVs, and all modern browsers. HLS segments video into small chunks and adjusts quality dynamically based on the viewer's bandwidth.
• MPEG-DASH (Dynamic Adaptive Streaming over HTTP) — an open international standard for adaptive bitrate streaming. DASH is codec-agnostic and works with H.264, H.265/HEVC, VP9, and AV1 content.
• HDS (HTTP Dynamic Streaming) — Adobe's adaptive streaming format for Flash-based players. While declining in usage, some legacy platforms still require HDS support.
• Pseudo-streaming — HTTP-based progressive download with seek support for HTML5 video players. Enables viewers to jump to any point in a video without downloading the entire file first.

What types of content does the CDN deliver?

While our CDN is optimized for video, it efficiently delivers all types of static and dynamic content. Video on demand (VOD) platforms benefit from edge caching that stores popular content close to viewers. Live streaming setups use our CDN for real-time segment distribution across multiple edge nodes. Large file downloads such as software distributions, game patches, and media archives benefit from high-throughput delivery with resume support. Static website assets (images, CSS, JavaScript) are accelerated through intelligent caching and compression.

How is CDN pricing structured?

CDN solutions from KVS Service are custom-designed based on your project's requirements. Pricing depends on the number of CDN nodes, geographic distribution, total bandwidth, and expected traffic volume. Unlike shared CDN providers that charge per-gigabyte rates with unpredictable bills, our dedicated CDN nodes provide flat-rate bandwidth that you can fully utilize. Contact our sales team for a consultation — we will analyze your traffic patterns and design an optimal CDN architecture with transparent pricing.

Can I combine CDN with a dedicated server?

Yes — and this is the most common deployment pattern for our clients. Your dedicated server acts as the origin server where your CMS (such as KVS) and database run. CDN edge nodes pull content from the origin, cache it, and serve it to end users. This architecture offloads the majority of bandwidth from your origin server, allowing it to focus on dynamic content generation and administrative tasks. We handle the full setup including DNS configuration, SSL certificates, cache rules, and health monitoring for all CDN nodes.

Why choose KVS Service CDN over shared providers?

Shared CDN providers like Cloudflare or AWS CloudFront are excellent for general-purpose websites, but video streaming has unique requirements. High-bitrate video content needs guaranteed bandwidth — not best-effort delivery shared with millions of other websites. Our dedicated CDN nodes provide consistent throughput even during traffic spikes, with no throttling or surcharges. Additionally, our team has deep expertise in video streaming infrastructure — we understand the specific configuration requirements for HLS manifests, CORS headers, range requests, and cache invalidation that generic CDN providers often handle incorrectly.
