Shortly after VMworld  I posted about my experience using vCloud Express. One of the things that I expected to see but found missing from the solution was the ability to perform virtual machine (VM) uploads and downloads between my own vSphere infrastructure and the hosted VMware environment. To be able to move my workloads (running on VMware VMs) from my private data center to the cloud or visa versa was an expectation I had based on the federated and private cloud discussions I’ve listened to over the past year. I expected to be able to at least manually export or import an OVF, but unfortunately did not find that capability while testing.

Before continuing allow me the liberty to reference a common expression - Can’t see the forest for the trees:

“An expression used of someone who is too involved in the details of a problem to look at the situation as a whole”

VMware has created the opposite scenario described in this expression with their concept of the Cloud. That is, VMware has allowed us to visualize what the forest will be before we have the trees. Of course, they had to. Was anyone besides Amazon talking Cloud before that, and if they were, was anyone even considering allowing companies to create their own internal clouds? I’d have to say VMware put the concept in my head. All I can say for sure is that I know I wasn’t listening to Cloud discussions before VMworld 2008.

Getting back to my vCloud Express testing and expectations, I was finally looking at the trees instead of the forest. I have since found some interesting information about how these trees are growing (if you will). To complete my reference, some of the details about VM transfer between private and public clouds are revealed by a VMware project has been privately referred to as Project Redwood.

So, we should all know what VCE stands for by now, right? Let’s say it together: “VMware, Cisco, EMC.” Using a bad analogy of Adam Lambert, a contestant on American Idol last season, the three companies “came out of the data center” today and publicly announced what we already knew; they’ve been working together to build the most integrated cross technology cloud infrastructure solution known to mankind. They are so integrated they’ve cross trained each other’s support staff so that anyone of the three partners can be a single “choke point” for those customers that implement vBlock Architecture. They call their union a “Computing Environment Coalition.” At the same time, EMC is promising that VMware can continue to “play the field” with technology partners that want to hook up. Hey, if you love somebody let them go. if they come back then it was meant to be!

Confused? Me too. Time will clear the fog and, as promised, reveal the vBlock based Cloud.

VCE vBlock is big, bad, and designed for scale like VMworld 2009 Infrastructure (without being told as much, my bet is that what we saw at the bottom of the stairs in the Moscone Center was a vBlock test drive). Apparently, VMworld’s spotlight on vCloud Express provider Terremark was another hidden VCE vBlock showcase from Vmworld. It all was happening in plain sight. If we only knew then what we know now. 

My thoughts (or this rant) can best be described as “now what!?”. I’ve spent the last 5 years figuring out how to design customized, application specific, performance optimized, and product feature specific virtual infrastructure designs for the enterprise data center. This is because I’ve listened to everybody explain that a “cookie cutter” infrastructure is not adequate for their solutions. Change this setting for feature A, provision these LUNs for feature B, add these VLANs for feature C, etc., etc. Now, VMware, Cisco, and EMC have figured out all the tough stuff and come up with a “connect the dots” data center reference architecture to make it easy to move to the Cloud? Really? I mean, I know we’ve been told this had to happen in order for the Cloud to work, but REALLY?!! Oh well, the only constant is change.

Ok, I feel a little better. Anybody else care to vent?

Here’s some more random links and quoted information to help others with similar change anxiety issues as me. Read the rest of this entry »

When vCloud Express was announced along with the vCloud API at VMworld 2009 in September I decided to sign up and try building VMware virtual machines (VMs) in the Cloud for myself. Being able to provision infrastructure as a service (Iaas) virtually with only a credit card has a certain useful appeal to me, and I wanted to see firsthand exactly what can be done and how much it costs.

This post summarizes my experience and touches on Terremark’s various options for building VMware Cloud VMs. I also quickly describe/illustrate the difference in charges for Linux versus Windows Cloud servers. This post contains a lot of screen shots, and at the end I’ll offer some opinions on the usefulness of vCloud Express and where this service might make sense for IT shops.

SQL Server 2008 R2: Virtualization for Databases is a post by Brent Ozar that I had to read slowly and multiple times. Not because it was hard to understand or read, but because the idea it provoked for me gave me the sensation of riding “The Merry Mixer” at the annual traveling amusement park. Ozar’s post explains that SQL Server 2008 R2 introduces the concept of a SQL Server Utility which groups multiple SQL servers as a pool of resources. Ozar explains:

“Looking ahead, Microsoft wants us to start thinking of databases as being less connected to physical servers, and to think of our physical servers as a resource pool.  Imagine if databases were self-contained packages that could be moved from server to server – just like virtual servers can be moved from host to host today.”

The SQL Utility will be managed by a Control Point Server that will collect and monitor configuration and performance data. This server will also facilitate moving SQL databases between Utility members. Apparently this migration of SQL databases will be able to happen live.

SQL 2008 R2 is planned to be released in the first half of 2010.

When I considered how virtual infrastructure (VI) could be impacted by this new technology is when I got a little motion sickness. What if Read the rest of this entry »

The fact that Microsoft has embraced virtualization is an understatement. The fact that Microsoft has been slow to embrace other virtualization vendor’s capabilities to run Windows operating systems as guests is equally an understatement, but what if this wasn’t the case? That is, what if Microsoft abandoned the licensing strategy of anchoring Windows to physical hardware? What if the folks at Redmond recognized virtual hardware and virtual machines (VMs) as equals to physical devices when assigning licenses? Taking it a step forward, what if specialized versions of the various Windows operating systems and applications were specifically developed for VMs along with special licensing? Maybe it will never happen, but there have been a few signs recently that give one hope for the possibility.

Like crop circles, the following are some posts that caused me to wonder “what if?”. Read the rest of this entry »

Just like with VMworld Europe 2009, I am again having to try to figure out the best ways to keep up with a virtualization event I can not attend in person.  Even though the simulcast will be live the chances of me getting to sit and watch it look slim. So, here are my ideas on how I plan to to follow the April 21 VMware Launch Event from afar while I work my way through the day.

A couple of weekends ago an email discussion started among the authors at GestaltIT.com about cloud computing. As I remember it (yes, I am too lazy to check for the actual first email) we started on Friday and replied back and forth until Sunday night. The results of those replies are slowly forming as posts about real world, enterprise infrastructure concerns and opinions about implementing and migrating to Infrastructure As A Service (Iaas). Governance And Peaks In The Cloud written by Joerg, Martin, and Stephen is the first post to be published from this dialogue.

“As large organizations begin to look towards cloud computing, many find themselves questioning the suitability of the infrastructure for their business needs. As consumer-focused services like Carbonite lose data and startup-focused systems like Amazon EC2 and Microsoft Azure suffer outages, the image of the cloud has darkened. How are providers protecting the data? What RTO and RPO is offered? Are these sufficient for the types of applications being considered for the cloud?”
