  21. 21. Puppet Eco-system It’s all about the integrations •  Broad platform support •  Flexible •  Great support •  Ops Friendly •  Unix, Linux and Windows •  Desired State Why Puppet? Configura>on Management Enterprise
  22. 22. Configuration Management Moving up the stack! Install VM Configure Agent Set custom facts Apply base profile Apply customroles +profiles Networking Disks Services+SeOngs Backup Monitoring Hardening Compliance Time Services Etc. Platforms Windows 2008 / R2 Windows 2012/ R2 Centos 5,6,7 Red Hat 5,6,7 Solaris, AIX (Roadmap)
  23. 23. Puppet Eco-system It’s all about the integrations •  Stability •  Predictability •  Multi-platform •  High Quality •  Managed by Puppet Why? Automated Acceptance Tes>ng Enterprise
  24. 24. Puppet Eco-system Module CI/CD Pipeline syntax check Auto puppet-lint unit test acceptance test Merge to TEST Auto Auto Manual Merge to PROD Manual Change in git Periodic trigger NoLfy by mail & Hipchat Fail Fail Fail Fail
  25. 25. 1.  kpn_jenkins::pipeline::module { 'kpn-puppet-forge/puppet-kpn-hosts': 2.  test_platform => ['linux', 'windows'], 3.  pe3_syntax => false, 4.  pe4_syntax => true, 5.  pe4_unit => true, 6.  pe3_unit => false, 7.  acceptance_test => true, 8.  acceptance_platform => [ 'centos-7-x64-pe4', 9.  'windows-2008r2-x64', 10.  'windows-2012r2-x64', 11.  'windows-2008r2-x64-pe4', 12.  'windows-2012r2-x64-pe4', 13.  'windows-2016-x64-pe4', 14.  ], 15.  hipchat_notification => true, 16.  hipchat_room => 'Module team', 17.  email => ‘', 18.  } 25 Puppet Eco-system Adding a module to the pipeline Which tests do you want to run? Which opera>ng systems do you want to run the code on? How do you wish to get no>fied?
  26. 26. Puppet Eco-system It’s all about the integrations •  Familiar Developer Workflow •  Easy to manage •  Easy setup •  Security (RBAC) •  Support •  Integrations Why GitHub Enterprise Version Control Enterprise
  27. 27. Puppet Eco-system It’s all about the integrations •  Nodes •  Platforms •  Applications •  Modules •  Module versions •  Puppet run info •  Nodes in NOOP mode •  Puppet facts •  Configuration Changes •  GitHub commit details •  Capacity Management •  Patch Management •  Compliancy •  Real Time Troubleshooting About?

  28. 28. Benefits & Challenges Making progress…..but not there yet Benefits Challenges v Operational Intelligence (Troubleshooting) v Standardizing the brownfield! v Auditability v PCI DSS compliancy v Data is far more reliable v Quickly modify generic configuration changes v Growing community v Online Documentation v Etc. v Adoption is still slow v Steep learning curve v Brownfield still painful
  29. 29. What did we learn Current State Technology v ~ 4000 nodes……and counting! v 30 Puppet Masters v 129 Puppet modules 87 in-house developed 42 Puppet Forge v 22 teams on boarded People v 170 Puppet Fundamentals v 100 In-house technical training v 25 In-house non-technical training Lessons Learned v Have infrastructure capacity for testing purposes v Training is good, just doing it is better v Get the right feedback fast v Monitor the change….closely v Don’t over-centralize v Start with Greenfield first. v You cannot please everybody
  30. 30. Roadmap Strengthen and improve Roadmap Items Provisioning v Infrastructure deployment with Terraform v Image management using Packer (In progress) Configuration Management v Application Orchestration v Microsoft DSC integration v Docker integration for automated testing Analytics v Improve Splunk integration Collaboration v Extend the use of GitHub v Implement ChatOps KEEP INNOVATING!
