1. MONGREL 2 Will Speak

2. A STORY or how Mongrel 2 came to be

3. RAGEL in the beginning there was the state machine compiler

4. RAGEL STATE MACHINE COMPILER ⇒ Compiles state machines into code

5. tokenising, regex & parser combines

6. fast and efficient parsing

7. MONGREL then came a

8. Ruby webserver Rock solid HTTP parser Easily scalable

9. ØMQ along came a whole lot of nothing

10. Provides a brokerless messaging architecture where clients and servers communicate

    via a Berkeley Sockets style interface “

11. a standard socket looks just like

12. a standard socket far more than

13. MONGREL 2 Add them all together and you get

17. synchronous http requests offloads

18. persistent state async protocols &

19. A PROTOCOL or what Mongrel 2 can do for us

20. REQUEST/RESPONSE a millisecond in the life of a mongre2 request

21. None

22. Request 1 Server IIS-01 Headers { “method”: “post”, … }

    Path /LockedQueueNoSql Body { “name”: “willspeak”, “affiliates”: [ …. ]}

23. Request 1 Server IIS-01 Headers { “method”: “post”, … }

    Path /LockedQueueNoSql Body { “name”: “willspeak”, “affiliates”: [ …. ]}

24. Request 1 Server IIS-01 Response [ { … }, {

    … }, …. ]

31. NETSTRINGS simple data serialisation

32. 12:hello world!, prefixed by length data encoded as UTF-8 assemble

    the delimiter committee

33. PACKETS inside the envelope

34. 12:hello world!, prefixed by length data encoded as UTF-8 assemble

    the delimiter committee

35. REQUEST PACKET FORMAT IIS-01 1 hello/world 2:{},4:body, webserver id requested

    path numeric request id netstring encoded json request headers netstring encoded request body

36. RESPONSE PACKET FORMAT IIS-01 1:1, hello Mongrel2 webserver id response

    data space-separated netstring of response ids
