Is there such a thing as a private cloud? Cloudscaling's Troy Angrignon participated in a panel on private cloud at Citrix Synergy 2011 in San Francisco on May 26, 2011. The conclusions: - All three of the panelists agreed that there is such a thing as private cloud. - Carpathia specializes in building high complexity custom private clouds. - There are two types of clouds: legacy clouds for highly regulated, complex client/server type IT stacks and webscale clouds for less regulated, web/mobile, greenfield and simpler stacks that need to scale. - Panel discussed how those two models (legacy cloud and webscale cloud) could be found inside (private) or outside (public). - Key is to realize that applications should always be moved to the platform that is appropriate for the application, use case, regulatory requirement, elasticity requirement.

9. Cloud is a textbook case study in disruption

10. New competitors are emerging in this wave that
are disrupting those who came before them.

11. We could automate everything
Citrix Synergy Private Cloud Panel May 26 2011 11

12. Once it was automated, we could run at scale
Citrix Synergy Private Cloud Panel May 26 2011 12

13. Scale enables an order of magnitude change in the
economics

14. Economics will drive adoption. Public cloud economics
are overwhelmingly attractive.
Public clouds:
• have 80% lower
TCO.
• are 40x more cost-
effective for SMBs
• are 10x more cost
effective for
enterprises

15. A Tale of Two Clouds
Citrix Synergy Private Cloud Panel May 26 2011 15

16. Myth: “Enterprises don’t use public clouds for
security, compliance or performance reasons.”
Citrix Synergy Private Cloud Panel May 26 2011 16

17. Truth: Enterprises use webscale clouds for
green eld web and mobile applications
Citrix Synergy Private Cloud Panel May 26 2011 17

18. Myth: Companies need to move the legacy apps and
all of their complicated plumbing into the cloud
Citrix Synergy Private Cloud Panel May 26 2011 18

19. Truth: Green eld web and mobile apps are driving
cloud growth, not migration of legacy apps
Citrix Synergy Private Cloud Panel May 26 2011 19

20. So two classes of clouds have emerged:
“enterprise” and “public”.
We call them “legacy” and “webscale”

22. Webscale clouds work well for global, low-
regulation, web & mobile green eld applications
with low network complexity...FOR NOW.
