Oxy: the journey of graceful restarts
Any software under continuous development and improvement will eventually need a new version deployed to the systems running it. This can happen in several ways, depending on how much you care about things like reliability, availability, and correctness. When I started out in web development, I didn’t think about any of these qualities; I simply blasted my new code over FTP directly to my /cgi-bin
Oxy: Fish/Bumblebee/Splicer subsystems to improve reliability
Oxy: Fish/Bumblebee/Splicer subsystems to improve reliability04/20/2023 At Cloudflare, we are building proxy applications on top of Oxy that must be able to handle a huge amount of traffic. Besides high performance requirements, the applications must also be resilient against crashes or reloads. As the framework evolves, the complexity also increases. While migrating WARP to support soft-unicast (

Oxy is Cloudflare's Rust-based next generation proxy framework03/02/2023 In this blog post, we are proud to introduce Oxy - our modern proxy framework, developed using the Rust programming language. Oxy is a foundation of several Cloudflare projects, including the Zero Trust Gateway, the iCloud Private Relay second hop proxy, and the internal egress routing service. Oxy leverages our years of expe
Donning a MASQUE: building a new protocol into Cloudflare WARP
Donning a MASQUE: building a new protocol into Cloudflare WARP06/22/2023 When we originally announced WARP, we knew we were launching a product that was different from other VPNs. Cloudflare has not only hundreds more data centers than your typical VPN provider, but also a unique purview into the adoption of open Internet standards. The confluence of these two factors have led us to today’s announ
Production ready eBPF, or how we fixed the BSD socket API
Production ready eBPF, or how we fixed the BSD socket API2022/02/17 As we develop new products, we often push our operating system - Linux - beyond what is commonly possible. A common theme has been relying on eBPF to build technology that would otherwise have required modifying the kernel. For example, we’ve built DDoS mitigation and a load balancer and use it to monitor our fleet of servers. Thi
Unimog - Cloudflare’s edge load balancer
As the scale of Cloudflare’s edge network has grown, we sometimes reach the limits of parts of our architecture. About two years ago we realized that our existing solution for spreading load within our data centers could no longer meet our needs. We embarked on a project to deploy a Layer 4 Load Balancer, internally called Unimog, to improve the reliability and operational efficiency of our edge n

Introducing Cache Reserve: massively extending Cloudflare’s cache05/11/2022 This post is also available in 日本語. One hundred percent. 100%. One-zero-zero. That’s the cache ratio we’re all chasing. Having a high cache ratio means that more of a website’s content is served from a Cloudflare data center close to where a visitor is requesting the website. Serving content from Cloudflare’s cache means i
Cloudflare StreamでSRT/RTMPSを使った低遅延ライブストリーミング再生のサポートが発表されました！ | DevelopersIO
はじめに 清水です。先週、CloudflareではPlatform Weekと題して様々な発表を行っていました。本エントリではこの中でもCloudflare Streamについての発表を扱います。ライブストリーミングをSRTもしくはRTMPSを使ってをより低遅延で行う再生サポートが発表されました、遅延は1秒未満とされています。現在はオープンベータ版という状況のようです。 Stream with sub-second latency is like a magical HDMI cable to the cloud 現在主流となっているストリーミングサーバからエンドユーザの視聴デバイス（ラストマイル）への配信方式は、HTTPをベースにしたHLSやMPEG-DASHなどです。これらはCDNと相性がよく（一般的なHTTPのCDNが利用可能）、またJavaScript製動画プレイヤーを利用してWe
