Altitude NYC 2018: Harmonizing HTTP and internet scale | Patrick McManus, Mozilla
Text to Speech
HTTP was easy in the beginning - DNS resolved a hostname, TCP connected you to the server, and then you sent a friendly GET to read some content until the connection closed and everything was settled. That remains the mental model and it worked very well except that every aspect of early HTTP fought against the way the Internet is really built. At times performance really struggled. The last 20 years have been a journey in harmonizing the HTTP model with the scale and security needs of the real Internet. We're now living in a world of binary multiplexed HTTP that may run without TCP or DNS at all. I will tell the story of how QUIC, Alternative Services, HTTP/2, Host Coalescing, Origin-Extension Routing, Secondary Certificates, and DNS over HTTP are forming the future of the world's most successful application layer protocol.
