The document discusses the benefits of using C++ for web servers and APIs, highlighting frameworks such as Crow and Docker for deployment. It emphasizes faster startup times and efficiency in handling sessions, while detailing Docker's utility for solving development and deployment issues. Additionally, it covers deploying containers to Heroku and mentions future steps for improvement and integration.
Fast C++ Web Servers
- 1. Fast and Easy Web Servers and APIs in C++ SoCal Code Camp 10/11 November 2018

- 4. Agenda • Why C++ and Docker? • Crow Web Server • Creating a build container • Running locally • Create a deploy container & Heroku • Future Steps
- 6. Why C++? • Faster startup time • Handle more sessions simultaneously • Need less servers, spend less money • Modern C++ is awesome

- 14. Docker • Operating system level virtualization • Also know as containerization • Initial release Mar 13, 2013 • Apache License 2.0
- 15. What Docker Brings? • Solves development problems • Solves deployment problems
- 16. Development Problems • Polluting you dev box • Installing the right libraries
- 17. Deployment Problems • It doesn’t work in production • Deploying too much stuff • Knowing if it is safe to upgrade
- 18. Creating a volume • docker run -v <host>:<container> -ti <image> bash • -v: the volume option • host:container • -ti: terminal interactive mode • image: the name of the docker image to launch • bash: the name of the app to run
- 19. Opening a Port • docker run -v <host>:<container> -p <host port>:<container port> -e PORT=8081 <image> <app to run> • -e opens a port • -e creates an environment variable
- 20. Viewing the examples • docker build -t beastbox . • docker run -v /beast:/usr/beast beatbox:latest bash • docker ps • docker cp <id>:/usr/src/beast_http_server ~/ Desktop/beast
- 21. Building the examples • cd /usr/beast/beast_http_server • mkdir build && cd build • cmake .. • make
- 22. Running an example • examples/ex1_server/ex1_server • ctrl-C to exit out of the server
- 23. Fixing the example • Address must be 0.0.0.0 • Port should be read from an environment variable • To rebuild, run make again
- 24. Exposing a Port • -p 8080:80 • Translates the host port 8080 to the container port 80 • -e PORT:8080 • Creates an environment variable named PORT with the value “8080” (a string)
- 26. Heroku • Cloud Platform as a Service • One of the first cloud platforms • Available since June 2007 • Supports Ruby, Java, Node, Scala, Clojure, Python, PHP, and Go • Applications run in Dynos
- 27. Containerize It • docker ps • docker cp . <id>:/usr/beastweb
- 28. Deploy It • heroku login • heroku container:login • heroku create • docker build -t hello_beast . • heroku container:push web -a floating-headland-31085 • heroku container:release web -a floating-headland-31085 • heroku open -a floating-headland-31085
- 29. Seeing the Logs • heroku logs -a floating-headland-31085
- 30. Next Steps • Better integration between my IDE and Docker (Especially debugging) • Adding HTML pages • Adding WebSocket
- 31. Is Crow Dead? • Last commit Dec. 27, 2017 • List of issues growing • List of pull request growing too
- 33. Boost Beast • Added to Boost in 2016 • Created by Vinnie Falco • Header-only • But low-level, not a server or a client • https://www.youtube.com/watch?v=uJZgRcvPFwI
- 34. Beast HTTP Server • Uses C++14 and Boost Beast • Header-only • Begun Jul 24, 2018 • Last commit Oct 8, 2018 • https://github.com/0xdead4ead/beast_http_server
- 35. Useful Links • https://www.docker.com/ • https://www.heroku.com/home • https://www.linkedin.com/learning • https://github.com/0xdead4ead/beast_http_server • https://github.com/ipkn/crow • https://github.com/boostorg/beast
- 37. Summary • There are C++ web servers • The payoff is fast initial response and more bang for the buck • Docker makes things easier, but debugging is challenging • You can deploy your containers to Heroku for free
