Edge-Caching

Content Delivery Networks: Speeding Up Global Websites Content Delivery Networks (CDNs) are groups of servers spread around the world. When a user visits your site, the CDN tries to serve most files from a nearby edge location instead of reaching back to your origin every time. If the file is already cached on that edge, it travels a short distance and loads quickly. If not, the edge fetches it from your origin and stores a copy for next requests. This simple approach cuts network hops, lowers bandwidth from the origin, and helps pages stay fast even during traffic surges. ...

Video Streaming Architecture: Delivering Smooth Viewing Video streaming aims to move a video file from a creator to a viewer with smooth playback. A solid architecture serves many devices and networks. The goal is fast start, steady quality, and few pauses, even when bandwidth changes. How a streaming pipeline comes together A streaming system works in four parts: encoding, packaging, delivery, and playback. Each part plays a key role. Ingest and encoding: the source video is captured and encoded into several quality levels. Packaging and manifests: the video is wrapped into formats like HLS or DASH and paired with a guide, the manifest. Delivery network: content travels through servers and often a content delivery network (CDN) to be close to viewers. Player and ABR: the app on the viewer’s device reads the manifest, measures speed, and picks the best quality. Adaptive bitrate streaming in practice Adaptive bitrate streaming (ABR) creates a ladder of quality levels. The player monitors bandwidth and buffer health, then switches up or down as needed. With ABR, a viewer with a strong connection sees higher quality, while a slower link avoids long rebuffering. Formats such as HLS and DASH support this approach. ...

Content Delivery Networks: Speed, Scale, and Reliability Content Delivery Networks (CDNs) place copies of your site’s content on servers around the world. This helps bring data closer to users, so pages load faster. Most sites serve static files from the CDN and keep dynamic content on the origin server. The result is faster, more reliable delivery for visitors from many regions. Speed comes from edge caching and proximity. The CDN stores images, CSS, and scripts on many edge locations. When a user requests a file, the edge server responds first. If the file is not cached, the edge fetches it from the origin and caches it for next requests. ...

Content Delivery Networks and Global Performance Content Delivery Networks (CDNs) help deliver web assets quickly by placing copies of content in geographically dispersed edge servers. When a user requests a page, the CDN routes the request to the nearest edge node, reducing latency and avoiding long journeys across oceans. This simple idea powers faster websites, smoother video streams, and a better mobile experience. Why speed matters is clear. People expect fast pages. Slow sites lose visitors, conversions drop, and search engines favor speed. A small delay can push users away, especially on mobile or in regions with varying network quality. CDNs address these issues by bringing content closer to readers and devices. ...

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: Speeding Up Global Access Content Delivery Networks, or CDNs, are groups of servers placed near users around the world. They copy and serve your static files from a location close to each visitor, which cuts travel time and speeds up page loads. How they work: When someone visits your site, the CDN routes the request to an edge server near that person. If the asset is cached there, it is served immediately. If not, the edge fetches it from your origin server, returns it to the user, and stores a copy for next time. ...

Video Streaming: Delivery, Quality and Monetisation Video streaming shapes how we watch movies, learn new skills, and follow live events. Behind every smooth play is a path that starts at the source and ends on a viewer’s screen. This article explains three core ideas—delivery, quality, and monetisation—and keeps the language clear for practitioners, managers, and developers. The goal is to help you plan better, compare options, and choose practical steps that fit your audience and budget. ...

Video Streaming Technology: Delivery at Scale Delivering video to millions of viewers is more about the path than the pixels. A good video may be high quality, but it must reach devices fast and reliably. This article explains the core ideas behind delivering video at scale, using simple terms and practical patterns. At scale, the goal is to keep video ready for the viewer with minimal buffering, even when traffic spikes. That means fast access to content, the right quality for each connection, and clear visibility into performance. By combining caching, adaptive bitrate, and reliable delivery paths, a stream can stay stable from the first frame to the final cue. ...

Video Streaming: Delivery, Quality, and Latency Video streaming connects viewers to moving images through origin servers, content delivery networks (CDNs), and edge caches. The goal is smooth playback with minimal delay, no matter where the user watches. Providers encode multiple bitrates and package content into chunks that players fetch using streaming protocols like HLS or DASH. A key technique is adaptive bitrate (ABR): the player switches between qualities based on current network speed and device capability. ...

Building Scalable APIs for Global Apps Global apps face unique challenges. Traffic comes from many regions, devices have different latencies, and rules for data privacy can vary by country. A scalable API returns fast responses and keeps the same behavior as you add servers. Design with statelessness, predictable latency, and clear contracts so new regions or teams can join without breaking existing clients. Start with stable endpoints and a simple auth flow that works everywhere. ...
