2 Before we start Get involved! Audience participation is encouraged and requested. Feel free to post updates to your social media platform of choice I encourage you to take photos or videos of today’s session and share them online This presentation will be made available online after the event

3 Architecture

4 vSphere and OpenStack have very different origins Those origins greatly influenced the resulting architectures vSphere originated as a way to provide virtualized infrastructure OpenStack originated as a way to provide consumable infrastructure services Different origins

5 (picture of hammer and nail)

6 (picture of multiple tools)

7 Loosely coupled vs. tightly coupled (more on that in a moment) API driven Multiple hypervisors (KVM, Xen, vSphere, Hyper-V) Multiple disk formats (QCOW, RAW, VMDK...) Integrated networking Key architectural attributes

8 OpenStack architecture

9 vSphere architecture

10 Architectural mapping

11 Terminology

12 Virtual machines and instances

13 Custom VMs and flavors

14 Templates and images

15 Virtual disks and volumes

16 Operations

17 Cloud instances are disposableVMs are not uniqueTune and groom apps not the cattleReplace when necessaryShoot the cattle when it is sick Cattle vs. pets Virtual Machines needs care and feeding Name the VM Tune and groom regularly Feed pets with good food and supplements Take pets to the vet when they are sick

18 No vSphere-style HA using KVM with libvirt

19 Instance evacuation Without Shared Storage The instance will be booted from a new disk, but will preserve the configuration, e.g. id, name, uid, ip...etc. With Shared Storage The instance will be booted from same disk and data will be preserved

20 vMotion and Storage vMotion

21 Instance migration

22 OpenStack storage options

23 Ephemeral storage

24 Block storage

25 Object storage

26 Differences in how networking is handled really reflect the architectural differences in OpenStack and vSphere Networking in vSphere is a bit more separate OpenStack networking is more integrated Networking
