Overview
OnApp CDN is a federated content delivery network designed for hosting providers, utilizing spare capacity in OnApp Clouds to deliver content globally. It supports HTTP push, pull, and streaming/live streaming, catering to hosting providers and enterprises managing web content delivery. The platform integrates with OnApp Cloud, enabling users to leverage a network of edge servers for improved performance. It is primarily used by service providers and enterprises needing scalable CDN solutions. The service is operational as of August 16, 2025, with recent updates enhancing its reporting capabilities.
Viblast was a Bulgaria-based company founded in 2013 that specialized in peer-to-peer (P2P) video streaming solutions, offering Viblast PDN and Viblast Player for live and on-demand video delivery. It served broadcasters, content providers, and CDNs, leveraging WebRTC and HTML5 to enable plugin-free HLS and MPEG-DASH playback. The company aimed to reduce bandwidth costs and improve stream quality for high-concurrency live streams. As of 2023, Viblast is reported as out of business, with no active services or official website available.
Network & Architecture
OnApp CDN operates a global network of Points of Presence (PoPs) by leveraging spare capacity from OnApp Clouds, though specific PoP counts are not publicly detailed. It uses a federated model, combining edge servers from multiple cloud hosts to ensure broad geographic coverage. The platform supports content delivery across regions including North America, EMEA, APAC, and others, with synchronization between CDN and OnApp Cloud occurring every 20 minutes by default. Regional strengths include flexibility for hosting providers, but limitations may arise from reliance on third-party cloud capacity, potentially affecting consistency in less dense regions.
