39. OPERATING SYSTEMS ARE ASSHOLES @gmiranda23 @cfgmgmtcamp
40. The good @gmiranda23 @cfgmgmtcamp • MACHINE ABSTRACTION LAYER • MACHINE PORTABILITY • APPLICATION PORTABILITY
41. The BAD @gmiranda23 @cfgmgmtcamp • IDIOSYNCRASIES • AMBIGUOUS CONFIG MGMT • BLINDSPOTS • SUPPORT
42. The BAD @gmiranda23 @cfgmgmtcamp • IDIOSYNCRASIES • AMBIGUOUS CONFIG MGMT • BLINDSPOTS • SUPPORT
43. The BAD @gmiranda23 @cfgmgmtcamp • IDIOSYNCRASIES • AMBIGUOUS CONFIG MGMT • BLINDSPOTS • SUPPORT
44. The UGLY @gmiranda23 @cfgmgmtcamp
45. The UGLY @gmiranda23 @cfgmgmtcamp
46. The UGLY @gmiranda23 @cfgmgmtcamp • CONTAINERS • INSERTING A FULL OS • AUDITABILITY
47. what we learned along the way @gmiranda23 @cfgmgmtcamp
48. @gmiranda23 @cfgmgmtcamp • OS IS GREAT FOR MACHINE MANAGEMENT • UI IS FOR HUMANS • STRIPPED DOWN PACKAGING
49. A NEW HOPE @gmiranda23 @cfgmgmtcamp
50. • OS ABSTRACTION LAYER • STRIP OUT USER SPACE • APP RUNTIME LAYER • APP ARTIFACT WITH NO OS @gmiranda23 @cfgmgmtcamp
51. WHERE WE GO FROM HERE @gmiranda23 @cfgmgmtcamp
52. @gmiranda23 @cfgmgmtcamp • JUST ENOUGH OS • BUT WITH DEEPER CONFIG MGMT INTEGRATION * LOOK TO COREOS (CONTAINER LINUX)
53. @gmiranda23 @cfgmgmtcamp • ABSTRACTED RUNTIME FOR APPLICATIONS • PROBABLY NOT JUST LIMITED TO CONTAINERS LOOK TO CONTAINER MGMT PLATFORMS OR HABITAT RUNTIME
54. @gmiranda23 @cfgmgmtcamp • REMOVE THE IDIOSYNCRASIES • DO THIS AT THE APPLICATION PACKAGING LEVEL LOOK TO HABITAT PACKAGING FEATURES
55. @gmiranda23 @cfgmgmtcamp RECAP • JUST ENOUGH OS • UBIQUITOUS APPLICATION RUNTIME LAYER • ULTRA-THIN APP PACKAGING (NO OS!) ITERATE AND COMPARE NEXT YEAR
56. @gmiranda23 @cfgmgmtcamp THANK YOU!
