Delivering Global Content with CDNs CDNs are networks of servers spread around the world. They bring copies of your content closer to users, so pages load faster even when visitors are far from your origin. How they work: edge servers cache static assets like images, CSS, and JavaScript. When a user requests content, the CDN serves it from the nearest edge server. If the item isn’t cached, it fetches it from your origin and stores a copy for next time. ...
Content Delivery Networks for Fast Global Access Content Delivery Networks (CDNs) are a practical way to bring your content closer to visitors around the world. By placing copies of assets on many servers at different locations, a CDN shortens the distance data must travel. The result is faster page loads, smoother video playback, and a more reliable website during traffic spikes or sudden events. When a user requests a file, the DNS resolves to a nearby edge server. If the asset is cached, the edge serves it immediately. If not, the edge fetches it from the origin, stores a copy, and serves it to the user. This cache-first approach reduces origin load and speeds up repeat visits. Dynamic content can also be delivered at the edge with smart rules. ...
Streaming Media Protocols: RTMP, HLS, DASH Streaming media helps you reach audiences on phones, tablets, and desktops. Three common protocols guide how video is sent and played: RTMP, HLS, and DASH. They share a goal—deliver reliable video—but they handle encoding, packaging, and delivery in different ways. RTMP in brief Real-Time Messaging Protocol (RTMP) was built by Adobe for live video from encoders to servers. It runs over TCP and keeps a steady stream between the source and the first server. In controlled networks, RTMP can offer very low delay, but today browsers do not play RTMP directly. You usually ingest RTMP to a server, then repackage for delivery to viewers. This path is common for live shows and events that need quick turnarounds. ...
Streaming Media Tech: Encoding, CDN, and Playback Streaming media blends encoding, delivery networks, and playback software. A smooth experience depends on choosing the right codecs, building efficient bitrates, placing data close to viewers, and delivering from compatible players. This article explains the three core pieces—encoding, a content delivery network, and playback—in plain terms with practical notes. Encoding basics Encoding turns raw video and audio into a compressed stream. The main decisions are codecs (H.264, HEVC, AV1), containers (MP4, WebM), and bitrate ladders. A simple setup creates several versions: 480p, 720p, and 1080p, each with its own audio bitrate. This allows an adaptive player to switch to the best quality without stopping playback. For live events, low latency profiles and chunked formats help reduce delay. ...
