Today, we are going to know that How does Netflix works. You can laugh but there was not quite anything like popping over to one of the 9,000 locations. The had Globally renting a gently used copy of home alone on VHS and settling down in the glow of your CRT tube Television. Of course, once the internet came along and Netflix with it. Blockbusters stores became all but a memory as there are now only a dozen of them left in the United States mostly in Alaska do too outrageous broadband prices so intuitively.
You had thought that it would take a rather massive enterprise to pull the rug out from under literally thousands of Brick-and-mortar stores and you had to be right during periods of peak usage. Netflix accounts for over a third of all downstream Internet Traffic in the United States a third but exactly how do they fling videos to so many people at once do they just have one giant server farm that constantly pours episodes of house of cards and family guy onto the Internet backbone not exactly like many other large sites focused on media delivery.
Netflix uses a content delivery network or CDN to store and transmit movies and TV shows you see although Netflix’s entire library could certainly fit on a few servers housed in a single building. There are some problems with this approach one locations far from that facility would suffer from high latency not what you want for streaming video.
This architecture would be basically the definition of a bottleneck since a single connection that fast that doesn’t exist and if it did it would be astronomically expensive and there it would mean a single point of failure that could cause Netflix's entire service to go down. If something happened at that one location a CDN solves these problems by utilizing redundant servers in multiple locations to serve many geographic areas. More quickly to balance server load between them so they don’t get overworked and to ensure that there will be backups in case of an incident or outage at one or even several locations.
But Netflix, in particular, takes this concept a step further because they are so big they actually work directly with a number of ISP’S to install their own hardware these boxes called open connect appliances at either exchange pints or even within the ISP’S facilities of video each these come overloaded with close to the entire Netflix library so what this means for you the consumer is that instead of connecting to some super far away land server to watch a movie.
Netflix data packet doesn’t have to fight with all other internet traffic that is upstream from your ISP and when it’s time for catalog updates Netflix pushes them to these appliances during the morning when there is a typically less internet Traffic overall meaning that by the time everyone gets home from work ready for a night of binge-watching the repository of content at their ISP.
Netflix uses Amazon Web Services or AWS a massive cloud processing that Netflix can quickly buy more time on in the form of virtualized servers as their customer base and traffic volume grows and it’s also very failure tolerant due to high amounts of redundancy but wait a second. Amazon has prime video things but they are trying to get everyone to buy. Why in the world would they let Netflix a huge competitor use their servers?
Well Amazon does make quite a bit of money from their deal with Netflix possibly into the range of hundreds of millions of dollars and may not want to start pushing out certain customers just because they might compete in a different market segment, I mean think of how Samsung manufactures chips that Apple puts in their phones because if.
Amazon wants to be the go-to company for cloud processing. They can’t behave in that way it is kind of like how Comcast wouldn’t stop you from watching a Disney the movie through their internet service yet do you find yourself racing against the clock as a freelancer or small business owner do you have trouble keeping track of your accounting and expenses and your invoices Fresh books cloud accounting software is the solution for you
