Many great ideas at Netflix begin with a question, and three years ago, we asked one of our boldest yet: if we were to entertain the world through Live — a format almost as old as television itself — how would we do it?
在 Netflix，许多伟大的想法始于一个问题，三年前，我们提出了一个最大胆的问题：如果我们要通过 Live 娱乐世界——这种格式几乎与电视本身一样古老——我们将如何做到？
What began with an engineering plan to pave the path towards our first Live comedy special, Chris Rock: Selective Outrage, has since led to hundreds of Live events ranging from the biggest comedy shows and NFL Christmas Games to record-breaking boxing fights and becoming the home of WWE.
最初的工程计划旨在为我们的首个实时喜剧特别节目Chris Rock: Selective Outrage铺平道路，后来发展为数百个实时活动，从最大的喜剧节目和NFL圣诞比赛到创纪录的拳击比赛，并成为WWE的新家。
In our series Behind the Streams — where we take you through the technical journey of our biggest bets — we will do a multiple part deep-dive into the architecture of Live and what we learned while building it. Part one begins with the foundation we set for Live, and the critical decisions we made that influenced our approach.
在我们的系列文章Behind the Streams中——我们将带您了解我们最大赌注的技术旅程——我们将对实时架构进行多部分深入探讨，以及在构建过程中学到的经验。第一部分将从我们为实时设定的基础开始，以及我们所做的影响我们方法的关键决策。
