Netflix relies on FreeBSD to build its in-house content delivery network (CDN). A CDN 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.
How long does it take to deploy Netflix on FreeBSD?

What kind of OS does Netflix use?
The content caches in the Netflix CDN, also known as Open Connect Appliances (or, simply, OCAs), run a lightly customized version of FreeBSD. In some ways, this is nothing special: many products are based on an open-source operating system.
What is Netflix’s CDN?
Netflix has built a CDN, called Open Connect, to distribute streaming media through most of the world. According to Sandvine, Netflix accounts for approximately 15% of all downstream traffic volume across the entire internet.
Why did Netflix choose FreeBSD?
In fact, Netflix serves 90 Gbps of TLS traffic on a single server with just 55% CPU usage. Netflix is a major FreeBSD contributor, and the CDN runs FreeBSD CURRENT (the development branch) since it gives features and bugfixes faster vs. RELEASE/STABLE versions.
Does Netflix still use FreeBSD?
According to developer Drew Gallatin, the popular streaming service is powered by AMD Epyc-7502P servers with 32 cores and 256 GB DDR4-3200 RAM. Four 100GbE connections are provided by two Mellanox ConnectX-6 Dx switches. They are running FreeBSD.

Is macOS based on FreeBSD?
FreeBSD is Just macOS Without the Good Bits This is as much a myth about macOS as about FreeBSD; that macOS is just FreeBSD with a pretty GUI. The two operating systems do share a lot of code, for example most userland utilities and the C library on macOS are derived from FreeBSD versions.

Is FreeBSD easier than Linux?
FreeBSD is a free and open-source Unix-like OS that powers desktops, servers, and embedded platforms. … However, the general consensus is that nearly all applications run faster on Linux than FreeBSD, but FreeBSD’s TCP/IP stack has way less latency (faster response time) than Linux.
Why is FreeBSD faster than Linux?
So it depends on what you’re talking about. The TL;DR version is: FreeBSD has lower latency, and Linux has faster application speeds. Yes, the TCP/IP stack of FreeBSD has far less latency than Linux. That’s why Netflix chooses to stream its movies and shows to you on FreeBSD and never Linux.
Why FreeBSD is more secure than Linux?
Vulnerability Statistics. This is a list of vulnerability statistics for FreeBSD and Linux.
