The document discusses virtualization as a method for consolidating server resources, improving efficiency, and reducing costs within organizations. It highlights the advantages of virtualization, including increased server utilization and simplified disaster recovery, while also noting potential disadvantages such as licensing costs and reliance on hardware. Case studies of 7-Eleven and Costco illustrate the successful implementation of VMware and Microsoft Hyper-V solutions, detailing hardware requirements and the expected impact on operational efficiency.

2. Growing requirements of processing: proliferation of servers, demanding
more energy, cooling, space

3.  WHAT IS IT ?
Virtualization is a software abstraction
of computer (hardware) resources.

4.  Virtualization products partition
physical servers in multiple virtual
machines. Each virtual machine
represents a complete system, with
processors, memory, networking, storage
and BIOS.
 Multiple virtual machines can share
physical resources and run side by side
on the same server.
 Operating systems and applications can
run unmodified in virtual machines.

5. HOW CAN IT BE USED
WITHIN AN ORGANIZATION
FOR ITS BUSINESS
PROCESSES ?
 By consolidation of servers,
isolation of processes, disaster
recovery, new software testing.
 Savings in costs, increased
reliability and availability, more
efficient usage of hardware
resources.

6. WHAT WOULD BE THE ADVANTAGES AND DISADVANTAGES OF
VIRTUALIZATION ?
Advantages:
#1 Decreases power, cooling, floor space and infrastructure.
#2 Simplifies disaster recovery and business continuity requirements.
#3 Increases server utilization from the typical averages of 5-15% to 60-80%.
#4 Faster deployment of information technology resources reduces time to market.
#5 Lower operational costs associated with reduced resource management and
administration.
#6 Improves application performance by dynamically adapting storage and server resources
to meet peek usage cycles.
#7 Aligns application data with the storage infrastructure to match application quality of
service requirements and lower cost per gigabyte.
#8 Improves protection and recovery of critical business data.
#9 Easier to secure and comply with regulatory requirements such as SOX, HIPPA and
eDiscovery.
#10 Nearly 60 percent of Fortune 500 companies are implementing virtualization in their
data centers, and another 30 percent are developing plans to do so. This means a growing
available pool of qualified professionals.

7. Disadvantages
#1 Licensing costs.
#2 Vulnerable to server failure.
#3 Compromise of virtualized hosts will affect guest machines.
#4 Additional guest servers will require their own administration measures.
#5 Initial cost can be high – renewal of associated infrastructure must be added
(newest processors, storage).
Personal Note : the Cons part wont
have to be presented in such a way,
it is only used as a way to anticipate
potential aversions coming from
some local IT specialists

8. Once an organization realizes the advantages
of going into virtualization, several
considerations are to be taken:
 Strategy (replace, expand)
 What systems to virtualize.
 Operating systems involved.
 Hardware platforms.
 Administrative Issues.

9.  Hardware reuse, replacement.
 Licensing issues.
 Legacy software considerations.
 Additional infrastructure expenses must
be considered (e.g. Energy efficient
cabinets, new network cabling....)
 Prototype testing
 Migration

28.  Mostly a Microsoft shop (1200 servers, 95% of them
on Windows products)
 Started virtualization efforts in 2006 (using MS
Virtual Server 2005, a previous, limited
virtualization product).
 As soon as hearing about Hyper-V, enrolled in MS
Virtualization Rapid Deployment Program.
 Using MAP tool (Microsoft Assessment and
Planning) server loads were evaluated, discovering
underutilized servers, good candidates for
consolidation.

29.  Initial phase: 50+ servers consolidated on 5 HP servers with Quad-
Core Intel Xeon processors.
 The server cluster has a core infrastructure that mimics the
production Costco environment
 Quality Assurance staff verifying reliability and stability before
rolling out new systems to internal customers and member
warehouses.
 By virtualizing existing servers instead of purchasing new physical
machines, Costco limited the proliferation of servers in its data
center.
 IT staff at Costco expects to achieve 40-45% virtualization by August
2009.
 Expected savings in energy costs, currently $75,000/mo (yet to
quantify).
 ROI not yet published (estimated?)

30.  Hyper-V lacks some advanced features of
VMware's ESX server and virtualization
platform, but its relatively low cost,
integrated physical and virtual management,
and ease of implementation might be good
enough for many organizations today.
 Microsoft-based shops will eventually
migrate to Windows 2008 and have access to
Hyper-V (Netscape history repeating ?)

31.  One important disadvantage of Hyper-V is its
requirement for 64-bit hardware. This excludes
many 32-bit based infrastructures that may
benefit greatly from virtualization, leaving
them to the competition.

32.  VMWARE claims to be less expensive
than MS-Hyper-V, mainly due to
Microsoft’s pricing model regarding
licenses of guest OSs, despite a higher
license cost per installation.
 VMWARE footprint: 32 MB vs HYPER-V
2 GB : bigger attack surface.
 VMWARE ESX server provides
sophisticated features not yet available in
MS-Hyper-V that can be very valuable in
high production environments.

34.  As newer operating systems and hardware
supporting virtualization appear, it will become
mainstream in every aspect of IT.
 Already prime consideration in the Data Center.
 Already an option in Storage.
 Strong consideration at the desktop level.
 Active development in the mobile
arena (e.g. Android Hypervisor
already in 1st phone)
 new approaches for enterprise
application development,access,
distribution.
