I pulled this chapter together from dozens of sources that were at times somewhat contradictory. Facts on the ground change over time and depend who is telling the story and what audience they're addressing. I tried to create as coherent a narrative as I could. If there are any errors I'd be more than happy to fix them. Keep in mind this article is not a technical deep dive. It's a big picture type article. For example, I don't mention the word microservice even once :-)
Given our discussion in the What is Cloud Computing? chapter, you might expect Netflix to serve video using AWS. Press play in a Netflix application and video stored in S3 would be streamed from S3, over the internet, directly to your device.
Another relevant factoid is Netflix is subscription based. Members pay Netflix monthly and can cancel at any time. When you press play to chill on Netflix, it had better work. Unhappy members unsubscribe.
The client is the user interface on any device used to browse and play Netflix videos. It could be an app on your iPhone, a website on your desktop computer, or even an app on your Smart TV. Netflix controls each and every client for each and every device.
Everything that happens before you hit play happens in the backend, which runs in AWS. That includes things like preparing all new incoming video and handling requests from all apps, websites, TVs, and other devices.
In 2007 Netflix introduced their streaming video-on-demand service that allowed subscribers to stream television series and films via the Netflix website on personal computers, or the Netflix software on a variety of supported platforms, including smartphones and tablets, digital media players, video game consoles, and smart TVs.
Netflix succeeded. Netflix certainly executed well, but they were late to the game, and that helped them. By 2007 the internet was fast enough and cheap enough to support streaming video services. That was never the case before. The addition of fast, low-cost mobile bandwidth and the introduction of powerful mobile devices like smart phones and tablets, has made it easier and cheaper for anyone to stream video at any time from anywhere. Timing is everything.
Building out a datacenter is a lot of work. Ordering equipment takes a long time. Installing and getting all the equipment working takes a long time. And as soon they got everything working they would run out of capacity, and the whole process had to start over again.
The long lead times for equipment forced Netflix to adopt what is known as a vertical scaling strategy. Netflix made big programs that ran on big computers. This approach is called building a monolith. One program did everything.
What Netflix was good at was delivering video to their members. Netflix would rather concentrate on getting better at delivering video rather than getting better at building datacenters. Building datacenters was not a competitive advantage for Netflix, delivering video is.
It took more than eight years for Netflix to complete the process of moving from their own datacenters to AWS. During that period Netflix grew its number of streaming customers eightfold. Netflix now runs on several hundred thousand EC2 instances.
The advantage of having three regions is that any one region can fail, and the other regions will step in handle all the members in the failed region. When a region fails, Netflix calls this evacuating a region.
The header image is meant to intrigue you, to draw you into selecting a video. The idea is the more compelling the header image, the more likely you are to watch a video. And the more videos you watch, the less likely you are to unsubscribe from Netflix.
The first thing Netflix does is spend a lot of time validating the video. It looks for digital artifacts, color changes, or missing frames that may have been caused by previous transcoding attempts or data transmission problems.
A pipeline is simply a series of steps data is put through to make it ready for use, much like an assembly line in a factory. More than 70 different pieces of software have a hand in creating every video.
The idea behind a CDN is simple: put video as close as possible to users by spreading computers throughout the world. When a user wants to watch a video, find the nearest computer with the video on it and stream to the device from there.
In 2007, when Netflix debuted its new streaming service, it had 36 million members in 50 countries, watching more than a billion hours of video each month, streaming multiple terabits of content per second.
At the same time, Netflix was also devoting a lot of effort into all the AWS services we talked about earlier. Netflix calls the services in AWS its control plane. Control plane is a telecommunications term identifying the part of the system that controls everything else. In your body, your brain is the control plane; it controls everything else.
In 2011, Netflix realized at its scale it needed a dedicated CDN solution to maximize network efficiency. Video distribution is a core competency for Netflix and could be a huge competitive advantage.
The number of OCAs on a site depends on how reliable Netflix wants the site to be, the amount of Netflix traffic (bandwidth) that is delivered from that site, and the percentage of traffic a site allows to be streamed.
Within a location, a popular video like House of Cards is copied to many different OCAs. The more popular a video, the more servers it will be copied to. Why? If there was only one copy of a very popular video, streaming the video to members would overwhelm the server. As they say, many hands make light work.
Right now, up to 100% of Netflix content is being served from within ISP networks. This reduces costs by relieving internet congestion for ISPs. At the same time, Netflix members experience a high-quality viewing experience. And network performance improves for everyone.
What may not be immediately obvious is that the OCAs are independent of each other. OCAs act as self-sufficient video-serving archipelagos. Members streaming from one OCA are not affected when other OCAs fail.
How do I sign into netflix on a computer with my Xfinity account? I want to browse and view programs and mark things to view later, but I can't sign directly into Netflix. I found an older post, but the link it references no longer works and just goes back to the Forums Home Page.
That sort of worked, thanks. I didn't exactly find settings with my User Name & Password but I did find what email address was registered under Help. So I was then able to do a password reset with Netflix. using that email address.
if you subscribe through your Xfinity subscription, go to the x1 Netflix app, and go into settings and account. you will find a menu item where you can get a username/password to access on other devices from that menu.
A year later I upgraded my computer and was going to sell the one I got last year, I went to do a full wipe of the drive and install Ventura OS. Upon setting it up and connecting to the internet I was presented with a message stating my device can be configured my Netflix remotely.
Of course I have no way of contacting Netflix IT to resolve this as I feel this is some mistake. Is there any way to get this unmanaged or removed? When I continue with the setup it takes to a screen where at the bottom I can see different servers like jamfcloud as if its trying to connect and then it brings me to a screen to sign in to google, if I do that it just errors out. My only way to bypass is to not connect to the internet but I had to downgrade back to Monetary in order to do so.
Hi. Unfortunately there is nothing anyone here on this forum can do to help with this (unless they happen to work in Netflix IT). What you're seeing is the device is enrolled in Apple Business Manager, and is trying to redirect the device to enroll in Netflix's MDM, which it sounds like is a Jamf cloud server. There's no way for an end user to bypass this. Only the company that the device is registered to can assist you.
If I may ask, where did you buy the Mac from? Was it someone selling it personally or a reseller of some kind? I'm sorry to say it, but there's as much a possibility that this Mac was stolen property and sold to you as it is that it's just a mistake on Netflix's part. The latter can and does happen of course. Sometimes devices are sold from a company and they forget to remove the device from Apple Business Manager.
If you're wondering why you didn't see the enrollment message back when you got it, but are seeing it now, well, a Mac can be enrolled in Apple Business Manager, but not actually be assigned to do remote enrollment on the Jamf server, and then later can be put into the queue for remote enrollment. So it's possible it wasn't set for enrollment at first, but somewhere along the line, got assigned to do the remote enrollment by someone at Netflix.
Sorry, I wish I could offer something more, but the only way to resolve this will be to somehow get in touch with Netflix corporate office and see if they can direct you to someone in their IT division. A quick Google search pulls this up for the numbers - (408) 540-3700 or (408) 540-3737. I would not try their regular customer service number as this is just for helping people with their Netflix accounts. I'm not surprised they have no idea where to direct you when you speak to them.

I hate to say it, but it's just as possible this is a stolen Mac sold to you as it is that Netflix made a mistake. Especially if you bought it from a person on the internet. Mistakes can and do sometimes happen. Occasionally companies sell older devices and forget to release them from Apple Business Manager, but they should be able to help you figure out the deal with it.
