The document discusses virtual appliances and provides guidance on how to build them. It defines a virtual appliance as software pre-installed on a virtual machine that can run on any hypervisor. It recommends building appliances using version control, continuous integration, and automated testing/deployment in virtual machines. It also covers packaging, security considerations, updating, and configuration management when building virtual appliances.

- 3. Then Became an Op
- 4. Senior Linux and Open Source Consultant @inuits.be
- 6. Building Virtual Appliances/Clouds since 2004
- 7. Surviving the 10 th floor test
- 9. Guest Editor at Virtualization.com
- 10. But mostly, a DevOp
- 11. Agenda What Is A Virtual Appliance ?
- 12. Build once, Run Everywhere
- 13. Why people don't like Virtual Appliances
- 14. Why Build Virtual Appliances
- 15. So you are building a Virtual Appliance ?
- 16. What Is A Virtual Appliance ?
- 17. Examples:
- 18. Where to get them ? TurnKey Linux: http://www.turnkeylinux.org/
- 20. Rpath :
- 21. LMGTFY
- 22. the software vendor himselve
- 25. Build once, Run Everywhere Remember a fellow called Duke in 1996 ?
- 26. His “VM” just got bigger
- 30. Support Multiple VM's in 1 package
- 31. Defines : CPU, Memory, Network, Storage
- 32. NOT OVF File Format
- 33. Conversion between fileformats still needed e.g VMDK to VHD (Xen)
- 34. But there are some availble
- 35. OVF in products VirtualBox
- 36. RHEV as of v2.2 import and export available
- 37. Citrix Labs : Project Kensho
- 39. Why people don't like Virtual Appliances Doesn't fit with their deployment tools
- 40. Doesn't fit with their authentication infrastructure
- 41. Doesn't fit with their standard database
- 42. Doesn't fit with their backup infrastructure
- 43. Doesn't fit with their operating system of choice
- 44. Why people don't like Virtual Appliances Security Who did build this device ? What about updates ?
- 45. Did we mention authentication ?
- 46. How secure is the application
- 47. The application servers ?
- 48. The Firewall ?
- 49. Image Sprawl, your update nightmare Image sprawl Copy VM, Deploy VM, Modify VM, Copy VM How do you patch 1 VM ?
- 50. Did you patch before or after that one was copied ?
- 51. How do you patch 100 VM's ?
- 52. What about machines that are offline ?
- 53. Image Sprawl, your update nightmare The biggest challenges we have in virtualization cloud are operational and organizational rather than technical. Christofer Hoff
- 54. Why Build Virtual Appliances Give customers a no fuzz working platform
- 55. Save potential customers time by giving them a working demo No wasted time trying to satisfy dependencies Technology Previews
- 56. Deploy your application on a virtual platform
- 57. A tool dedicated for virtual platforms (virtual networking, virtual security)
- 58. So you are building a Virtual Appliance ? What to firewall ? Subnet ?
- 59. Localhost ? Are you going to build LDAP/??? libraries in ?
- 60. How secure is the The Firewall ?
- 61. What about updates ?
- 62. How to build virtual appliances Rpath (Conary)
- 63. Suse Studio (Suse)
- 66. But , how do you build your own software / infrastructure ?
- 67. Your Software should be managed using version control
- 68. should build using a CI setup
- 69. should be tested in a test environment
- 70. Your Build environment should be managed using version control
- 73. Think deploy a VM , build software, transfer build results, destroy VM
- 74. Your Test Environment should reproducible
- 76. should automated
- 77. Think deploy a VM , test software, destroy VM
- 79. If my computer can't install it , the installer is borken
- 80. Reproducable
- 81. Think: Kickstart, FAI, Preseeding, SystemImager Suite Also in a VM
- 82. How to Upgrade ? Provide Public Repository Feature upgrades
- 83. Security upgrades Provide Fresh Images
- 84. Config Propagation Is this your config or Customer config ?
- 86. Hosted Cfg Mgmt tools
- 87. Config Propagation Is this your config or Customer config ?
- 89. Hosted Cfg Mgmt tools
- 90. Package & Ship Clocks HW vs Internal
- 91. Filesystems
- 92. Firewalls
- 93. Webmin
- 94. Vlan support
- 96. Automate
- 97. Situation normal, nothing must change
- 98. Devops
