Enjoy Netflix? 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. What do you think?

享受 Netflix 么？你应该感谢 FreeBSD
|
||||
======
|
||||
|
||||
Netflix 是世界上最受欢迎的流媒体服务之一。
|
||||
|
||||
但你已经知道了。不是吗？
|
||||
|
||||
你可能不知道的是 Netflix 使用 [FreeBSD][1] 向你提供内容。
|
||||
|
||||
是的。Netflix 依靠 FreeBSD 来构建其内部内容交付网络 （CDN）。
|
||||
|
||||
[CDN][2] 是一组位于世界各地的服务器。它主要用于向终端用户分发像图像和视频这样的“大文件”。
|
||||
|
||||
Netflix 没有选择商业 CDN 服务，而是建立了自己的内部 CDN，名为 [Open Connect][3]。
|
||||
|
||||
Open Connect 使用[自定义硬件][4]，Open Connect Appliance。你可以在下面的图片中看到它。它可以处理 40Gb/s 的数据，存储容量为 248 TB。
|
||||
|
||||
![Netflix’s Open Connect Appliance runs FreeBSD][5]
|
||||
|
||||
Netflix 免费为合格的互联网服务提供商 （ISP） 提供 Open Connect Appliance。通过这种方式，大量的 Netflix 流量得到了本地化，ISP 可以更高效地提供 Netflix 内容。
|
||||
|
||||
Open Connect Appliance 运行在 FreeBSD 操作系统上，并且[几乎完全运行开源软件][6]。
|
||||
|
||||
### Open Connect 使用 FreeBSD “头”
|
||||
|
||||
![][7]
|
||||
|
||||
你或许会期望 Netflix 在这样一个关键基础设施上使用 FreeBSD 的稳定版本，但 Netflix 会跟踪 [FreeBSD 头/当前版本][8]。Netflix 表示，跟踪“头”让他们“保持前瞻性，专注于创新”。
|
||||
|
||||
以下是 Netflix 跟踪 FreeBSD 的好处：
|
||||
|
||||
* 更快的功能迭代
|
||||
* 更快地使用 FreeBSD 的新功能
|
||||
* 更快的 bug 修复
|
||||
* 实现协作
|
||||
* 尽量减少合并冲突
|
||||
* 摊销合并“成本”
|
||||
|
||||
|
||||
|
||||
> 运行 FreeBSD “head” 可以让我们非常高效地向用户分发大量数据，同时保持高速的功能开发。
|
||||
>
|
||||
> Netflix
|
||||
|
||||
请记得，甚至[谷歌也使用 Debian][9] 测试版而不是 Debian 稳定版。也许这些企业更喜欢最先进的功能。
|
||||
|
||||
与谷歌一样，Netflix 也计划向上游提供代码。这应该有助于 FreeBSD 和其他基于 FreeBSD 的 BSD 发行版。
|
||||
|
||||
那么 Netflix 用 FreeBSD 实现了什么？以下是一些统计数据：
|
||||
|
||||
> 使用 FreeBSD 和商业硬件，我们在 16 核 2.6GHz CPU 上使用约 55％ 的 CPU，实现了 90 Gb/s 的 TLS 加密连接，。
|
||||
>
|
||||
> Netflix
|
||||
|
||||
如果你想了解更多关于 Netflix 和 FreeBSD 的信息，可以参考 [FOSDEM 的这个演示文稿][10]。你还可以在[这里][11]观看演示文稿的视频。
|
||||
|
||||
目前，大型企业主要依靠 Linux 来实现其服务器基础架构，但 Netflix 已经信任了 BSD。这对 BSD 社区来说是一件好事，因为如果像 Netflix 这样的行业领导者重视 BSD，那么其他人也可以跟上。你怎么看？
