14. jeffhung: 㑌೥౎ཁሜҰ ౟ PaaS
15. 20 RD + 6 months to built Elaster CAP
16. 5 RD + 6 weeks to bootstrap a private PaaS for our own
17. How?
18. We have a strong OPS team
19. do more with less don’t code anything
20. Apache HTTPd ++
21. Dispatcher done in httpd.conf

27. httpd.conf programming
28. function REDIS (cmd) { ... } # Call REDIS()?
29. # function REDIS (cmd) { ... } RewriteMap REDIS "prg:redis-cli --raw" # Call REDIS()? ${REDIS:cmd}
30. if url == "/index.html" redirect "/404.html" else if proxy "/app/...", "http://app/REDIS(app)"
31. # function REDIS (cmd) { ... } RewriteMap REDIS "prg:redis-cli --raw" # if url == "/index.html" # redirect "/404.html" RewriteRule ^/index.html /404.html [L,P] # else if # proxy "/app/...", "http://app/REDIS(app)" RewriteRule ^([^\/]*)/(.*) ${REDIS:GET\ $1}/$2 [L,P]
32. Live Demo simplified https://github.com/jeffhung/osdc-2013-lightning
33. The Actual httpd.conf • Authentication & Authorization • Customer Header Injection • Dispatching & Load Balancing

35. ~200 lines of httpd.conf And several filter scripts dash2under.pl: #!/usr/bin/perl $| = 1; # Turn off I/O buffering while (<STDIN>) { s/-/_/g; # Replace dashes with underscores print $_; }
