You Should Thank FreeBSD -====== - -Netflix is one of the most popular streaming services in the world. - -But you already know that. Don’t you? - -What you probably did not know is that Netflix uses [FreeBSD][1] to deliver its content to you. - -Yes, that’s right. Netflix relies on FreeBSD to build its in-house content delivery network (CDN). - -A [CDN][2] is a group of servers located in various part of the world. It is mainly used to deliver ‘heavy content’ like images and videos to the end-user faster than a centralized server. - -Instead of opting for a commercial CDN service, Netflix has built its own in-house CDN called [Open Connect][3]. - -Open Connect utilizes [custom hardware][4], Open Connect Appliance. You can see it in the image below. It can handle 40Gb/s data and has a storage capacity of 248TB. - -![Netflix’s Open Connect Appliance runs FreeBSD][5] - -Netflix provides Open Connect Appliance to qualifying Internet Service Providers (ISP) for free. This way, substantial Netflix traffic gets localized and the ISPs deliver the Netflix content more efficiently. - -This Open Connect Appliance runs on FreeBSD operating system and [almost exclusively runs open source software][6]. - -### Open Connect uses FreeBSD “Head” - -![][7] - -You would expect Netflix to use a stable release of FreeBSD for such a critical infrastructure but Netflix tracks the [FreeBSD head/current version][8]. Netflix says that tracking “head” lets them “stay forward-looking and focused on innovation”. - -Here are the benefits Netflix sees of tracking FreeBSD: - - * Quicker feature iteration - * Quicker access to new FreeBSD features - * Quicker bug fixes - * Enables collaboration - * Minimizes merge conflicts - * Amortizes merge “cost” - - - -> Running FreeBSD “head” lets us deliver large amounts of data to our users very efficiently, while maintaining a high velocity of feature development. -> -> Netflix - -Remember, even [Google uses Debian][9] testing instead of Debian stable. Perhaps these enterprises prefer the cutting edge features more than anything else. - -Like Google, Netflix also plans to upstream any code they can. This should help FreeBSD and other BSD distributions based on FreeBSD. - -So what does Netflix achieves with FreeBSD? Here are some quick stats: - -> Using FreeBSD and commodity parts, we achieve 90 Gb/s serving TLS-encrypted connections with ~55% CPU on a 16-core 2.6-GHz CPU. -> -> Netflix - -If you want to know more about Netflix and FreeBSD, you can refer to [this presentation from FOSDEM][10]. You can also watch the video of the presentation [here][11]. - -These days big enterprises rely mostly on Linux for their server infrastructure but Netflix has put their trust in BSD. This is a good thing for BSD community because if an industry leader like Netflix throws its weight behind BSD, others could follow the lead.
