  4. Why make this? • DOMjudge seems to be the most popular self-hosted CCS • Used by many regions(NWERC, SER USA, SOCAL, etc) • DOMjudge can be somewhat tricky to install if you aren’t a Linux person • Documentation is very good though • Overall Goal • Make the technical side of running a contest as easy as possible

  5. Why is this great? • Create contest in just a few clicks • Your own dedicated cluster of machines • Automatic scaling and redundancy • Custom subdomain • http://<your_contest_name>.cloudcontest.org • Permanent static scoreboard • Full database dump for download after the contest

  6. How is this different?
