Bringing Private Cloud to Australia

OpenStack on VMware OpenStack Summit 2013

SLIDE 2

Introduction

  • Aptira
  • Leading OpenStack provider in Australia and APAC
  • Private and Hybrid IaaS Cloud Solutions
  • Technology consultancy for large providers with huge scale and load requirements
  • Customers in Finance, Retail, Utilities, Government, Rich Media Producers
  • Founder/prime motivator of the OpenStack community in Australia and India
  • Sina Sadeghi
  • Director, Cloud Operations
  • I don't only write the puppet module, also need to determine which technologies are a

commercially viable solution for customers and where they fit in our strategy

  • Aptira employee since August 2012
  • Previously: sysadmin/ops for major Australian research and commercial institutions
  • Part of team that deployed the NeCTAR Research Cloud on OpenStack – currently 30,000

cores and 3,000 users.

Perception

  • Internal use-case
  • existing successful and growing business running on vSphere
  • 1. Buy new hardware, lease new racks
  • 2. Sina deploys greenfields OpenStack
  • 3. ???
  • 4. Profit!
  • External use-case
  • Build it and they will come

Reality: Internal use-case

  • vSphere had features we relied on for our bread and

butter (HA, DRS, secure live migration, power management, etc)

  • OpenStack relatively immature at the time
  • Only a few “cattle” customers, mostly “puppies”

customers

  • Deploying OpenStack would mean duplication of all

existing features in parallel

  • We love ghettoVCB
slide-5
SLIDE 5

Reality: External use-case

  • Australia is the most virtualised country per capita in

the world

  • vSphere approaches 80% of commercial virtualisation

solutions

  • Huge investments in training, documentation, change

control, DR, everything based on vSphere

Does it do vSphere HA? How does this compare to vSphere? How much does it cost? Other

slide-6
SLIDE 6

Reality

  • OpenStack “Vanilla” only meets requirements for
  • Greenfields
  • Service Providers
  • Public Cloud (or similar)
  • Want to use OpenStack?
  • CapEx for new hardware and datacenter footprint
  • Completely re-operationalise around OpenStack
  • Can you afford developer(s) to drive source in the direction you

require?

  • End up with two silos
slide-7
SLIDE 7

Pride/Prejudice

  • I am an Open Source geek
  • So is ~99% of the OpenStack “DevOps” community
  • VMware purchased Nicira and joined OpenStack

Foundation

  • Is this VMware versus OpenStack?
  • Watched VMware CTO promise their support for

OpenStack

slide-8
SLIDE 8

OpenStack + VMware

  • Hey, actually this is a really good idea!
  • It's not VMware versus OpenStack (but maybe it is

vCloud versus OpenStack)

  • Existing driver contributed by Sean Chen
  • Didn't really seem to work at all
  • nova-compute/nova-network model doesn't really fit
  • Let's work with VMware to get this usable!
slide-9
SLIDE 9

OpenStack + VMware

  • Started working with OpenStack@VMware team (special thanks Dan

Wendlandt, Shawn Hartsock)

  • Also working closely with Nicira which became VMware Networking and

Security Business Unit (special thanks Sumner Burkart, Jacob Cherkas)

  • Major focus: Show customers and potential customers that they can expose

their existing vSphere clusters as scalable IaaS clouds on open standards without significant CapEx or silo effect.

  • It can be done!
  • Expose existing infrastructure as new technology is a massive resource efficiency
  • As it should be: ESXi or vCenter “just another hypervisor”
  • Bring Private Cloud to Australia!

SLIDE 10

We have come a long way

  • Since Dan Wendlandt live-patched our Grizzly code at the

Havana summit

  • The code works (very well)!
  • Real documentation!
  • nova core dev at AOSUG Sydney noted the contributions

as impressive

  • https://bugs.launchpad.net/nova/+bugs?field.tag=vmware
  • http://docs.openstack.org/trunk/config-reference/content/vmware.html
  • We are excited to start change control for Havana!

Today - Images

  • 1. Download fresh Precise cloud image from:

http://cloud-images.ubuntu.com/precise/current/precise-server-cloudimg-amd64-disk1.img

  • 2. Convert to VMDK using "qemu-img convert" (locally on a linux machine)
  • 3. Convert using vmware CLI:

vmkfstools.pl --server=IPADDRESSOFVMHOSTorHOSTNAME -i /vmfs/volumes/SOURCEPATH/SOURCEFILENAME.vmdk /vmfs/volumes/DESTINATIONPATH/DESTINATIONFILENAME.vmdk

  • 4. Upload the image to glance:

glance image-create --name “IMAGENAME” --disk-format vmdk --container-format bare --public --property “vmware_adaptertype=lsiLogic” --property “vmware_ostype=ubuntuGuest” --property “vmware_disktype=eagerZeroedThick”

What works

  • We are using Ubuntu 12.04 Precise (with Ubuntu Cloud

Archive) virtual machines for OpenStack Grizzly infrastructure (keystone, glance, cinder, horizon)

  • We are using

https://github.com/openstack-vmwareapi-team/nova.git for nova (all services) – Grizzly

  • Keen to go back to using UCA for everything
  • We are using Nicira provided packages for Neutron and

physical commodity servers for Nicira

  • All important features work correctly!
slide-17
SLIDE 17

What doesn't work

  • Often a disconnect between reporting a bug and having that bug

implemented in “stable” and then included in UCA

  • nova console-log
  • Image interactions between glance/nova-compute/vmware datastores

leave something to be desired (not sure if technical fix is easy)

  • Snapshot semantics
  • Virtual machines don't launch in a tenant associated folder
  • Existing machines need an on-boarding process
  • Many minor issues fixed as of Havana!

Today: Internal use-case

  • Deployed and in production use
  • Peace of mind for existing technical staff
  • Offering unique solutions to our customers based on

OpenStack

  • Big Data
  • Digital Media Platforms
  • Easy to offer PaaS on top (HEAT, scalr, Docker, OpenShift,

CloudFoundry) for web hosting

  • Exploring multi-hypervisor multi-region configurations
slide-20
SLIDE 20

Today: External use-case

  • Offer Private Cloud to potential customers with no

infrastructure CapEx required

  • Australia wants to be able to provision their virtual

machines quicker

  • Australia wants to be able to provision their virtual

networks quicker

  • Australia wants to be able to offer utility model to

internal customers

  • Give Australia a platform to build “cattle” applications on
