Building Blocks of the Private Cloud is specially brought to you by SCS Enterprise Cloud Computing & Virtualisation SIG. Speaker Mr Daniel Mar, Principal Consultant with Infront Consulting Group, is an experienced consultant with over 12 years in the IT industry. He has been specialising in server virtualization for the past 7 years where he started by deploying technologies from VMware. He also picked up Citrix virtualisation solutions and now focuses on Microsoft Virtualisation and Systems Management. He has helped many companies move from a purely physical infrastructure to a highly available virtual infrastructure and also help them deploy private cloud infrastructures.

Others – OS/2 Warp, MS DOS 6.22, Netware,
eComStation
• Support for literally every x86 based OS out there – according to
the VMware website – 390 Guest OS

13. Summary of Guest Support
• Extract from the VMware website*
• It’s not all about how many guests OS are
supported but – What Guest OS would typically
be deployed to your Private Cloud?
• Ensure VMTools, XenTools or Integration
Components are installed in the Guest OS.

14. Private Cloud platform features
• Features that you look for in a Hypervisor to enable you to create a
fully scalable, resilient and highly available private cloud.

16. Migrating Workloads into the
Cloud
• We need a method to migrate existing physical
workloads into our Private Cloud
• Two ways to migrate workloads - V2V or P2V
• A brief look at the P2V tools provided by the vendors
• If none of these tools migrate your workload – do it
manually or go for a 3rd party solution – e.g PlateSpin
Migration, Quest vConverter, Symantec System
Recovery

19. Private Cloud Hypervisor
Summary and Use Cases
XenServer, Hyper-V and vSphere will provide for most of the features and
capabilities required by Private Cloud infrastructures today. Considering the
most recent OS versions for Windows and Linux, all 3 have very good support.
XenServer Hyper-V vSphere
• Simple to • Pure Microsoft • Where cost is not
implement and shop an issue
deploy • Cost is a concern • Enterprise class
• Supports large • Comprehensive features and
number of Linux management – scalability

27. Final Words
• Vendors products are constantly improving
levelling the playing field.
• Management is more important than the
Hypervisor
“Virtualization without good management
is more dangerous than not using
virtualization in the first place.”
– TOM BITTMAN - GARTNER VP AND ANALYST, 9 MAY, 2007
• The Hypervisor is just the technology, don’t
forget about people and processes.
Virtualization Will Drive Major Change in IT Infrastructure and Operations in the Next Three Years, Tom Bittman, May 8, 2007
