VMWare 5.x Vs Hyper-V TCO

Beware of this whitepaper!


VMWare compares Hyper-V 2008 R2 and System Center 2008 R2 versus vSphere 5.x.

The last Microsoft virtualization suite is the 2012 R2 (Hyper-V 2012 R2 and System Center 2012 R2)

It’s like comparing a brand new Yamaha R1 with a 5 years old Honda CBR 1000…

It’s not fair!




Changing in VMware HA with vSphere 5.x

VMware is a great virtualization solution but since the first version the High Availability feature had a weakness that I never liked.

A vSphere 4.x cluster for example use a primary/secondary node architecture: the first 5 hosts that join the VMware HA cluster are automatically selected as primary nodes.  All the others are automatically selected as secondary nodes.

That means that no matter how many nodes your cluster has, if all the 5 primary nodes are down, your entire virtualization environment is unusable.

Microsoft Hyper-V doesn’t have this limitation because uses a classic Windows Clustering feature that uses node and disk majority.

Now with vSphere 5.x the HA feature has changed to avoid this behaviour.

The concept of master and slave still exist but it’s dynamically assigned so if the master fall down, a new master role will be assigned to a slave.

This great article can explain in depth the changes made to the vShpere 5.x architecture.


Let’s start to know Microsoft and Amazon Public Cloud solutions

Since the beginning of my career I used virtualization. As a Microsoft employee I used for my projects Virtual Server 2005, 2005 R2, Hyper-V 2008,

2008 R2, 2012 and now 2012 R2. I also know and respect very much the VMware products/solutions.

Now that the next “big thing” seems to be the cloud computing, I found that I’m a Private

Cloud expert! (thanks to my knowledge of System Center suite that completes the

Microsoft/VMware virtualization platform and achieve the Private Cloud solution) and I also

found that I was not aware about “the other side”: the Public Cloud.

So I started to learn the Microsoft Azure offering that is very interesting due to the tight

integration with the Microsoft On Premise/Private Cloud solution (aka Hyper-V + System Center

+ Azure Pack)

Now it’s turn to take a look to the competitors and due the fact that VMware is still

considering how to enter in the Public Cloud market, the best choice is to learn what Amazon

is doing with Amazon Web Services (that it’s the actual leader for Public Cloud solutions).

I recommend to start reading this short PDF (14 pages) published in 2008.

http://media.amazonwebservices.com/AWS_Cloud_Architectures.pdf The value of this doc is that shows in a really clear manner an example of how to use cloud

computing to create a reliable, scalable and efficient solution.

I love the fact that this document presents a real example and uses it to talk about every

single component of this solution and leads the reader to think about the technology used and

the best practices taken.

I think that the “GrapTheWeb” solution can also be created with Microsoft Azure with the

following architecture:


Microsoft offers an Hadoop clustered distribution service called Windows Azure HDInsight:


The AWS Hadoop offering is named Amazon Elastic MapReduce:
