3. What is Fedora • A community • Linux distribution • What might become Red Hat Enterprise Linux
5. F19 - Schrödinger's cat From science experiment to 'making new things' • Developer's Assistant • 3D modelling and printing • OpenShift Origin • node.js • Ruby 2.0.0 • MariaDB https://fedoraproject.org/wiki/F19_release_announcement
6. F19 - Schrödinger's cat ... and so many features are related to 'Cloud' • OpenShift Origin • OpenStack Grizzly • Virt Storage Migration • systemd Lightweight Containers • QXL/Spice KMS Driver • ... http://fedoraproject.org/wiki/Releases/19/FeatureList
7. What is this ... ... and why does it all matter to Fedora ? • OpenShift Origin (PaaS) • OpenStack Grizzly (IaaS) • oVirt (IaaS)
8. What is this ... ... and why does it all matter to Fedora ? • SaaS (Software as a Service) • PaaS (Platform as a Service) • IaaS (Infrastructure as a Service)
9. What is this ... ... and why does it all matter to Fedora ? • Full virtualization (hardware) • Paravirtualization • OS level virtualization • Containers • Etc.
10. What is this ... ... and why does it all matter to Fedora ? • Hypervisor • SElinux • KVM • LXC
11. What is this Hypervisor Virtual Machine Monitor is a piece of computer software, firmware or hardware that creates and runs virtual machines.
12. What is this Hypervisor Virtual Machine Monitor Hosted (type 2); needs an OS • VirtualBox, VMware Workstation Native (type 1); bare metal • XenServer, VMware ESX(i)
13. What is this virtualization full virtualization A full machine is virtualized. Unavailable (needed) hardware is emulated. Runs unmodified OS. para-virtualization Virtualization method where parts of the OS talks to an API. Runs only modified OS.
14. What is this KVM full virtualization solution for Linux on x86 hardware containing virtualization extensions
15. What is this KVM full virtualization solution for Linux on x86 hardware containing virtualization extensions But … but... but... doesn't it also do para-virtualization?
16. What is this virtualization Hybrid ?
17. What is this OpenS[omething]
18. What is this OpenStack a cloud computing project to provide an Infrastructure-as-a-Service (IaaS).
19. What is this IaaS cloud-service model in which virtual machines and other resources are offered. A hypervisor, such as Xen or KVM, runs the virtual machines as guests.
20. OpenStack
21. OpenStack provides … a lot
22. OpenStack provides ...
23. How does this work KVM uses hardware extensions provided by your CPU. It can therefore reach near-native performance.
24. What is this ... ... and why does it all matter to Fedora ? • Hypervisor • SElinux • KVM • LXC
25. What is this OS virtualization operating system-level virtualization
26. What is this OS virtualization operating system-level virtualization provides a means to re-use system installed libraries.
27. What is this LXC operating system-level virtualization method for running multiple isolated Linux systems (containers) on a single control host.
28. What is this SELinux kernel feature that provides the mechanism for supporting access control security policies
29. What is this cgroups kernel feature to limit, account and isolate resource usage (CPU, memory, disk I/O, etc.) of process groups.
31. What is this OpenShift makes it easy for you to build your own Platform-as-a-Service (PaaS) infrastructure, allowing you to enable others to easily develop and deploy software.
32. What is this PaaS In this model cloud providers deliver a computing platform, typically including • operating system, • programming language execution environment, • database, • and web server.
33. What is this OpenShift
34. How does this work Containers Operating system-level virtualization where the kernel of the operating system is used for multiple isolated user-space instances. In addition to isolation mechanisms, the kernel can provide resource management features to limit the impact of one container's activities on the other containers.
35. How does this work Containers provide process-isolation possibility to allocate resources
36. How does this work Containers LXC / SElinux cgroups
37. How does this work Software deployment works by using git When code is pushed to the repository, hooks will perform actions on the post-update
38. We haven't even talked about ... VPS …
39. We haven't even talked about ... VPS … Can be a container or a full virtual machine.
40. We haven't even talked about ... Virtual Appliance ...
41. We haven't even talked about ... Virtual Appliance … Configured virtual machine for easy deployment.
42. We haven't even talked about ... AWS ...
43. We haven't even talked about ... Heroku Docker ...
44. We haven't even talked about ... oVirt ...
45. We haven't even talked about ... SPICE Libvirt ...
46. So, what does this mean ... Fedora is a general Linux distribution, but most of it's core technology is either aimed at a general user or running it as server on mind.
47. So, what does this mean ... • Red Hat Enterprise Linux • CentOS
48. So, what does this mean ... Voices in the community consider a 'Core' concept; a small core which can serve as a basis for Desktop or Server... … or any other purpose where you see fit.
49. So, what does this mean ... … or any other purpose where you see fit. For example, • Embedded? ARM? • Virtual Appliances? Containers? • ...
