20 Evolution of web development infrastructures

21 Assumptions Version control Issue tracking Deploy scripts Project not yet 'live' Internal and external clients

22 When you assume... $u = $me = Photo by Gabor Karpati

23 Single server

24 This project doesn't have the budget for more than one server. Screen capture from The IT Crowd, Channel 4

25 I hope you didn't just save foobar.php because I haven't checked in my changes all day. Screen capture from The IT Crowd, Channel 4

26 Did I just find a bug, or did you expect that bit to be broken? Screen capture from The IT Crowd, Channel 4

27 The client is reviewing the site. Can you not break anything for the next week, while you add these features? Screen capture from The IT Crowd, Channel 4

28 Single server

29 Single server (realistic)

49 How can I reduce hardware costs?

50 But, you already HAVE a server. Screen capture from The IT Crowd, Channel 4

56 Copying servers

57 Run identical web dev setup on Linux... on Windows (... on OS X, too, but not for free.)

58 Eases transition to Linux

59 A few notes on hardware Get lots of RAM Get lots of disk space For servers, get SCSI

60 How can I reduce setup time?

61 Configuration management tools:

62 AutomateIt overview The big picture Package management Config file munging Services Easy to extend Etc, etc, etc

70 Benefit: documents your config

71 A system that works

72 Our web development infrastructure

73 VMware Server

74 Production virtual server

75 Staging virtual server

76 Development sandboxes

77 Version control

78 AutomateIt

82 Sandboxes = stability Photo by Giedrius M

83 Servers have consistent software

84 Develop on platform of choice

85 Reliable staging servers

86 Happy clients

87 Areas for improvement Issue 1: requires sysadmin skills Issue 2: consumes lots of disk Issue 3: exposes weaknesses in deploy systems
