1. Brisbane 2014 DevOps Days - Ignite Session Is the age of virtualisation already over? Sean Wilbur! @sgwilbur! about.me/sgwilbur 1
2. –Pythia “This has all happened before, and it will all happen again.” 2
3. So do we really care how it runs? ❖ Hardware! ❖ Virtualised! ❖ Container! ❖ PaaS! ❖ SaaS! ❖ Dude, it’s in the Cloud 3
4. As development, we are asked to deliver ❖ Business Value! ❖ Security! ❖ Availability! ❖ Performance! ❖ Repeatability! ❖ Isolation! ❖ Uniformity! ❖ Transportability! ❖ Separation of Concerns 4 Reference: #1
5. Development requires some design ❖ Need an architectural roadmap (JIT)! ❖ How to effectively do full stack DevOps! ❖ Virtual appliances! ❖ Chef, Puppet, Ansible, Salt …! ❖ Pattern based deployments! ❖ Too many options to leave this to development or operations or architecture to make these decisions in isolation 5
6. Full stack DevOps means we need to have meaningful things to say in the design meetings for that stack ❖ Infrastructure! ❖ Hardware! ❖ Local / DataCenter/ Cloud! ❖ Virtual ( on above )! ❖ Containers ( on above )! ❖ Software! ❖ App Stack! ❖ Persistence! ❖ Enterprise Bus! ❖ Continuous Delivery Pipeline! ❖ Tools/Technologies! ❖ Process One does not simply deploy like it runs on your laptop 6
7. Virtualisation vs ParaVirtualisation ❖ OS is ignorant! ❖ Support any OS we can virtualise HW for 7 ❖ OS is modified to support this! ❖ Support only OSes where we can modify the core OS Reference: #2
8. ParaVirtualisation and HyperVisors 8 Reference: #3 Hybrid model un-modified Operating System with option to improve performance via guest add-on drivers
9. HyperVisors vs Containers 9
10. Application isolation spectrum 10
11. Virtualisation is Over!
12. –James Turnbull! VP of Services at Docker, author of The Docker Book “Containerization is the new virtualization” 12
13. Container Options, Options, Options ❖ LPARs! ❖ Container Groups (cgroups) / chroot / FreeBSD jails! ❖ Solaris Global Zones / AIX WPARs / LXC! ❖ Docker / lmctfy /OpenVZ /Warden ! ❖ CoreOS / Deis / Flynn /Mesos / CloudFoundry / OpenStack 13
14. Linux natively supports containers 14 LXC
15. Docker 15
16. Containers are shallow and cheap, in a good way ❖ Containers are able to get near/host speed! ❖ Resources overhead is lower 16
17. Back to Full Stack Dev 17 ❖ Infrastructure as code! ❖ runtimes as cattle not pets! ❖ Operations Owned! ❖ Development Owned! ❖ ephemeral environments
18. Docker containers build once, run anywhere? 18
19. Containers everywhere ❖ LXC (OpenVZ, Virtuozzo, many shared hosting and vps providers )! ❖ CoreOS ( minimal OS for running Docker containers)! ❖ Kubernetes ( built on-top of Docker to manage containers at scale )! ❖ OpenStack ( Docker via Glance) 19
20. Containerize all the things! 20
