Cfengine presentation at the RMLL 2010 in Bordeaux. This presentation focuses on the reasons for configuration management, and how Cfengine addresses this need.

1. Cfengine presentation - Configuration management - Promise technology - Cfengine architecture - Cfengine syntax - Examples

3. 2009, cofounded Normation

5. Consulting on Identity and Service Management

6. Why should I manage configurations?

8. Automated operations on each servers,

10. Rollback on configuration files in case of error,

11. Self healing configuration from a defined reference.

16. Convergence is built in Cfengine Cfengine way Traditional scripts

17. Cfengine features

20. Use policy servers to distribute promises files to agents.

21. Cfengine architecture

24. Package management integration

25. LDAP and Database integration*

27. cf-agent : the cfengine agent,

28. cf-served : server for file sharing and external request,

29. cf-execd : scheduling daemon,

30. cf-runagent : helper program that talks to cf-served,

31. cf-report : generate reports on executions,

32. cf-know : generate topic map.

35. Cross platform (Linux, Unixes, *BSD, Windows, MacOS)

36. Few external dependencies (OpenSSL, [PCRE])

37. Very small memory footprint (between 2 and 30 MB)

39. Autonomous

40. Automated

41. Continuous operation

42. Reliable : only one vulnerability in 17 years
