1. Unikernels! … on behalf of a merry crew: Anil Madhavapeddy, Thomas Gazagnaire, David Scott, Thomas Leonard, Richard Mortier, Magnus Skjegstad, David Sheets, Balraj Singh, Jon Crowcroft, Mindy Preston, and many others! PolyConf July 2015 @amirmc Amir Chaudhry
2. Overview Unikernels Intro Why I care Deployments / Other work • What they are • Why they matter • Example scenario
 (static websites) Unikernels @amirmc
3. Overview PM in OCaml Labs (I herd cats) Community for MirageOS (moar cats) I like systems stuff! Background: Physicist, Neuroscientist, CompSci (ish), Startups, BigCo. @amirmc
4. Software today… …is an application … @amirmc
5. Software today… …is an application … … on top of an Operating System. @amirmc
6. Software today… … is built locally… @amirmc
7. Software today… … is built locally… … but deployed remotely. @amirmc
8. Software today… … needing more tools. @amirmc
9. Software today… …is complex! Even though most apps are single-purpose @amirmc
10. Complexity is the enemy… More layers -> tricky config Duplication -> inefficiency Large sizes -> long boot times More stuff -> larger attack surface @amirmc
11. Why build for clouds as we do for desktops? Can we do better?
12. Can we do better? Disentangle applications from the OS Break up OS functionality into modular libraries Link only the system functionality your app needs Target alternative platforms from a single codebase @amirmc
13. The Rise of the Unikernel Unikernels are specialised virtual machine images built from a modular stack adding system libraries and configuration to application code Every application is compiled into its own specialised OS that runs on the cloud or embedded devices MirageOS @amirmc
14. MirageOS @amirmc
15. MirageOS unikernel } @amirmc
16. MirageOS unikernel } Familiar development cycle Broad deployment scenarios @amirmc
17. MirageOS Unix Develop logic MirageOS System Libs @amirmc
18. MirageOS Xen Specialise for deploy… … to multiple environments @amirmc
19. So what?
20. Example: Static websites (though applicable to any application)
22. @amirmc
23. SMALL! @amirmc 8.2MB 102 kloc 2560 kloc ~200MB No extra stuff!
24. @amirmc
25. @amirmc Pluto just considering areas of the circles :)
26. Easy deployment
27. Develop Deploy Test Heroku for Unikernels Walkthrough @amirmc …in ~100 lines of code
28. Walkthrough
29. Heroku for Unikernels General workflow @amirmc …in ~100 lines of code Develop Deploy Test
30. Deployments @amirmc
31. Trade-off (for now) @amirmc
32. Why I care @amirmc Empower individuals Distributed personal clouds Resilient, scalable systems
34. Cloud Feudal Computing
35. @amirmc MirageOS (OS/application) Irmin (Storage/Sync) Signpost (Identity/Connectivity) OCaml (Safety/Modularity) Mail Contacts Calendar
