Types of Enterprises
6/9/2015 14

15. 15
What is an Enterprise?
Using myself as an example…
• Online Bond Trading Firm (Privately held, then publicly held)
• Pharmaceutical Company (Publicly held)
• Tech Company (Publicly held)
• Each enterprise had its own unique business
requirements, constraints, and risks

16. 16
Evolution of Enterprises
 Organizations are constantly growing and changing
 Many companies started small, but grew over time
 Pace of growth will often help define IT practices
 All enterprises are not created equal

17. 17
For Our Purposes…
 Two types of Enterprises
 Super Enterprise
 Everyday Enterprise

18. 18
OpenStack and the Super Enterprise

19. 19
What is a Super Enterprise?
 Companies with a great deal of IT engineering power
 Many times have a “we can build it better!” mentality
 Drive the direction of technology
 IT is seen as a business advantage

20. 20
OpenStack in the Super Enterprise
 Great Examples at OpenStack Summit 2015 Vancouver!

21. 21

~Walmart Labs Blog
• Scalability, as eCommerce is fueling the company’s growth
• Complete overhaul of technology stack
• Wanted the platform to best support application delvelopers
• No vendor lock in, they have the scale and the power to do it themselves
• Tweak OpenStack to fit their needs
• Community!

27. 27
OpenStack and the Everyday Enterprise

28. 28
What is the Everyday Enterprise?
 Mostly insourced IT
 IT may or may be seen as a business partner
• Often is seen as a cost center
 Cross functional people/teams
• Dabblers across the organization
 May have some silos

29. 29
OpenStack Challenges for the Everyday Enterprise
 Doesn’t have the engineering skill or time for tweaking OpenStack
to get it up and running
 Often needs to lean on vendors for support or services beyond
initial deployment
 Don’t have the credibility/leeway in the organization to try
something “open source”
 OpenStack is still seen as a relatively new technology at 5 years
old
• 5 year old VMware released ESX 2.5 for comparison

30. 30
More OpenStack Challenges for the Everyday Enterprise
 Organizational and Process challenges
• How can you automate the deployment of Application X when Bob is the only
one who knows how to do it and doesn’t document anything?
• Would you even allow your application teams to deploy an environment on
their own?
• OpenStack crosses lines between many teams, do they play nice?

31. 31
OpenStack for the Everyday Enterprise
 Distributions and
integrators are key
for the Everyday
Enterprise!

32. 32
Why Pay Someone for OpenStack?
 There’s no such thing as a free kitten!
 Distributions are easier to install and update
 Can call someone for support when it breaks
 Can also call someone to show up and build it and maintain it for
you
 Features enterprises need, such as HA for components, can be a
pain to set up unaided, and often require lots of Linux skill

33. 33
VMware Integrated OpenStack
 The VMware OpenStack Easy Button

34. 34
So Where is the Enterprise?
 VMTurbo conducted a survey with 1,284 respondents
• Results available on GitHub https://github.com/vmturbo/VMTurboSurvey
 Here’s what enterprises said:
• 28.4% see technical challenges around installation that result in
operational costs as the #1 challenge to OpenStack adoption
• 20.8% say their organizations aren’t ready for private cloud
• Adoption by Super Enterprises has made 43% of of those not running
OpenStack more interested in OpenStack
• 41.5% of respondents are investigating OpenStack for future deployment,
3.6% are already running it!
• 39.1% of those examining OpenStack are most excited about getting rid of
vendor lock in

35. 35
Introducing OpenStack to the Enterprise

36. 36
About:You
 You’ve had OpenStack running on your laptop or in the lab
for a while
 You’re comfortable sitting down with someone and giving
them a tour of OpenStack
 You’re comfortable talking about the different OpenStack
programs
 You think OpenStack would be a good fit for your
organization, and you want to go further
 You have an understanding of your organization’s business
requirements and how they relate to IT

37. 37
Getting Ready for “The Talk”
 Focus on a business problem
• What are you trying to solve?
• What benefit will it bring to the organization?
 Talk to other groups who will ultimately be involved
• Know your developers
• Know your ops teams
• Know your infrastructure teams
• Know your business stakeholders

38. 38
Having “The Talk”
 Start Small
• Don’t try to boil the ocean
 Anticipate objections
• What would your issues be if you were in your boss’ shoes
 Don’t get discouraged
• This project may not be the one

39. 39
Example: Alice the Infrastructure Architect
 XYZ Corp is looking to deploy a new internal web application for
time tracking, which will be constantly updated with new features
based on employee feedback
 Alice thinks this is a great application to pilot OpenStack with
• Internal, and low risk
• Alice used to work on the development team, and knows them very
well
• Alice believes OpenStack will allow the development team to spin up
their environments much quicker, and the QA team can also benefit
from this

40. 40
Example: Alice Talks to Her Boss, Bob
 Bob objects because he believes “OpenStack will be
too difficult to install and update”
• Alice proposes using an OpenStack distribution to streamline both the
deployment and update processes
 Bob is worried this will impact the multi-hypervisor
strategy XYZ corp has been looking to implement
• Alice assures Bob OpenStack can work with either of the
organization’s hypervisors and may even help them further enable this
strategy
 Bob is still weary
• Alice proposes deploying the application in parallel on OpenStack as
well as using their existing process.

41. 41
Dealing with a StackBlocker
 No one uses OpenStack
• Plenty of big organizations do (think keynote)
• Lots of “everyday enterprises do too” (think Superuser awards)
• Over 50% of OpenStack workloads are production (Superuser survery)
 Don’t touch my infrastructure!
• OpenStack can operate side by side with your existing infrastructure
• No rip and replace needed
 We don’t do science experiments here!
• NASA used to be a science experiment, now SpaceX
• Innovation is NOT a bad thing, tie it to business requirements

42. 42
Alice’s Next Steps
 Alice holds meetings with the dev, ops, and business
teams before bringing them all together before kickoff
• Alice converses with each team, and provides information in order to
address any fears and concerns, Ops has the most concerns
 Alice works with the Ops team to pick an OpenStack
distribution that fits their organization, in order to
further ease concerns
 In the end, OpenStack is preferred to the organization's
traditional methods!

43. 43
Key Takeaways
 Have a problem to solve with OpenStack
• Technology is cool, but we aren’t likely to get budget to deploy new
technology for the sake of deploying new technology
 Be ready to have many discussions throughout the
organization
• Things are most successful when everyone is onboard
• Chances are there will be many who don’t understand what
OpenStack is
 Seek continuous feedback throughout the process
• If someone isn’t happy, no one will be happy

44. 44
Community
 Don’t forget the OpenStack community! We’re here to help!

45. 45
To Sum Up The State of The Stack…
 OpenStack is ready
• Look at the super enterprises!
• Multiple distributions and services are available for deployment and operations
to aid Everyday Enterprises
 OpenStack is Coming
• The topic is hot. Make sure to arm yourself with knowledge about it, and how
it pertains to your organization
• “It doesn’t” is valid, as long as you know why!

46. 46
History Repeating
 Remember when virtualization wasn’t ready?
• Maybe you would use it for dev or test…maybe
 “This virtualization thing is never going to catch on”
 OpenStack is the next generation of technology
• Abstracting all the things, not just compute!
