Why Rackspace and Openstack may be too late

I wanted to take some time and make sure that I clarified my position on Openstack.  Rackspace and NASA announced this open source project back in July of 2010.  Openstack is a cloud manager for private or public clouds.  Openstack positions itself as an alternative to vCloud and through 3rd hosting provider party an (potentially) […]

Introduction to Cloud Computing – Cloud Manager


So, I normally teach this class as a two hour session and I had a heck of a time cutting out material and getting it down to something digestible for Internet (and slide deck) viewing. It’s a quick introduction to cloud managers and a continuation of my introductory cloud computing course.

OpenFlow and software defined networks are here. Now what?

People at the Open Networking Summit Earlier this month I spent a few days at the Open Networking Summit in Santa Clara, Calif. and walked away certain I watched history being made in the networking industry. The emergence of the OpenFlow standard and software defined networking have been on my radar…


Windows 8 running on a Samsung Series 7 Tablet

Today my employer hosted an internal conference and Microsoft just happened to be there which I wasn’t expecting.  Specifically, they were there showing off Windows 8 running on a Samsung Series 7 11.6” tablet. I had ran the Developer Preview of Windows 8 on my older HP tablet which was an OK experience but the hardware […]


My wife knows what’s wrong with Apple’s Cloud strategy

My wife asked me the other day how does she log into her iCloud and get some data?  This is the problem with Apple’s cloud strategy – My wife doesn’t understand it.  My wife is a typical user – not a geek or even a power user.  She uses her computing devices as a tool […]


“VMLimted” Microsoft taking pretty good shots at VMware

Microsoft’s VM-Limited campaign has pitted VMware’s cloud strategy as just more virtualization masked as a Cloud solution.  Microsoft hits on some of the pain points of VMware’s customers including the change in licensing model which the faux VMLimited sales person explains it as “The more you use the more you pay” model.  From the density […]

Cloud Computing

The Cloud isn’t (Just) about saving money

I’ve been in enough cloud engagements to realize that the Cloud is not (just) about saving money. Sure, you can reduce start-up costs and pay “On-Demand” for resources. If you have 1001 e-mail users you can subscribe to 1001 instances of Google Apps or Office 365 and pay for exactly what you use. Does that […]

Who do you trust with your data – Google, Microsoft or Dropbox?

For me the battle between Google Drive, Dropbox and Skydrive comes down to whom I trust with my data.  All of the solutions have very strong attributes.  Dropbox has the best and most widely adopted API’s.  Google has extremely strong integration with Google Docs and I’m sure superior search capability and Skydrive is a great […]

What are some of the considerations for Cloud based ERP?

Recently in one of my courses at DePaul we’ve talked at great length in class about the different ERP delivery models.  One model that seems pretty popular today is Cloud based ERP.  Provider’s such as Salesforce.com offers an ERP solution and before Oracle acquired PeopleSoft they actually offered a pseudo Cloud based solution for small […]

Think BYOD is an issue? Wait for Stealth IT

Originally posted on Gigaom:
The acronym BYOD, which stands for bring your own device, is taking over both corporate America and the press release filter in my inbox. But an analyst report out Monday suggests that BYOD has a flip side that no one talks about — Stealth IT, or the IT pro side of…

Is it too late for Openstack?

Originally posted on Gigaom:
There’s been a lot of news about OpenStack recently — notably a conference dedicated to the open-source cloud-computing platform this week and IBM and Red Hat (s ibm) (s rht) signing on to the effort. And yet there is a feeling in some quarters that  it may be too late for the project to take hold.…


What lessons can we learn about the cloud from Megaupload?

The Megaupload case represents one of the major challenges with the public Cloud.  The obvious issue for legal use cases for their service has been that non-infringing data is trapped in limbo along with the alleged infringing data.  One may say that a legitimate user should have seen this coming.  Megaupload’s primary use case was […]

XenDesktop 5 Provisioning Server support for vSphere 5.0

I’m a pretty big fan of XenDesktop.  It’s a slick and power VDI platform.  A while back I helped a small company deploy XenDesktop and they’ve really appreciated the migration from XenApp.  They are accessing the environment locally, remotely and via iOS devices.  It just works (for the most part). One design consideration I had […]

Review of PHD Virtual Backup 5.4

Sponsored Post What is PHD Virtual Backup? PHD Virtual Backup is a virtual server backup application that comes in two flavors – A version for Citrix XenServer and a version for VMWare ESXi.  This solution is geared toward a virtualized environment.  So, if you have a mix of physical and virtual servers you will need […]


Why do we even need VMWare’s CloudFoundry?

I live in Infrastructure as a Service (IaaS) and Software as a Service (SaaS).  Most of the projects I’ve been involved in have been around either building these services or deploying applications built on these services. It’s also easy to get customers to relate to single instances of VM’s hosted in the cloud or e-mail […]

Readers: What’s Your Cloud Strategy?

Originally posted on TechCrunch:
I get press releases every week about some new (or old!) company and their so-called cloud solution. Some folks are clearly abusing the popularity of the “cloud” buzzword, and others are actually doing interesting things with distributed computing, infrastructure- and platform-as-a-service, orchestration, and related technologies. Amazon is the prime mover on…

Microsoft, instead of turning the lights off on XP, make it open source

Network World’s Mark Gibbs wrote: “Perhaps Microsoft should turn these products loose, make them open source and leave the care and maintenance of them to people who care enough to do so. You know that instantly projects would emerge to work on core maintenance and then distros as wildly varied as those you find with […]

It’s official: IBM and Red Hat get with OpenStack

Originally posted on Gigaom:
OpenStack filled in some key checkmarks this week as it added IBM(s ibm) and Red Hat(s rhat) to its roster of corporate backers.  As GigaOM reported last week, the two tech giants will join the nascent OpenStack Foundation as Platinum members along with AT&T, Canonical, Hewlett-Packard(s hpq), Nebula, Rackspace(s rax), and Suse.

VMware isn’t going to let network virtualization pass it by

Originally posted on Gigaom:
VMware(s vmw) teamed up with Stanford and Berkeley on Tuesday to create an industry consortium around software defined networks, called the Open Networking Research Center. The company, famous for hypervisors that virtualize servers isn’t about to watch while companies attempt to build the same disruption in networking. The consortium counts CableLabs,…

Cord Cutting

Cord Cutting (Cable TV)

A little over 3 weeks ago I received my latest Comcast bill.  I was shocked that the price had gone up yet again.  This was the last straw for my wife who is a diehard cable user.  She gave me the OK to cut the cord.  I wasted no time in calling Comcast and scaling […]

Why you should have comments, even when they are bad

If you spend long enough reading blogs — or even newspapers, for that matter — you will eventually come across an essay about how a site is struggling with the question of whether to allow comments, or has decided to shut them down. The latest example of this genre comes from…

Social photo-sharing service Instagram is pretty proud of the infrastructure it built atop the Amazon Web Services (s amzn) cloud, but I have to wonder whether the startup’s acquisition by Facebook today means all that effort was for nothing. Well, it wasn’t for nothing, obviously — Instagram was able to scale…

Why Citrix Dumped OpenStack Support

I haven’t had time to review or weigh in on Citrix’s announcement on dropping support for OpenStack and embracing CloudStack.  I know since the announcement OpenStack has had a couple of major wins but I don’t think they come close to offsetting the loss of Citrix in the camp. Citrix really wants to compete in […]

BYOD is unstoppable

Originally posted on Gigaom:
The Bring Your Own Device (BYOD) movement has gained unstoppable momentum. And thanks to the burgeoning mobile app market, employees have high expectations for these tools. They want an attractive user experience tailored to their devices. In other words, companies need to invest in building apps, period. During my two decades…

Tim Armstrong may have saved AOL, but at what cost?

Google vs MS

Google Docs vs. Office 365

So MS announced a 20% reduction in the base price of Office 365.  I’m not a user of either Google Docs or Office 365.  I do use both gMail and Microsoft’s legacy hosted Exchange.  But as for office productivity I’ve stuck with my bloated desktop apps and I’m pretty happy. I received an advertisement from […]

Introduction to Cloud Computing – Virtualization vs Cloud

I’ve been wanting to start posting training video’s and this is a first for the blog.  This is an introduction to cloud computing which helps to differentiate Cloud Computing vs Virtualization.  Feedback here or on youtube is appreciated.


Hyper-V 3 vs. vSphere 5 Debate on ZDNet

Zdnet has an interesting debate about Hyper-V 3 on Windows Server 8 vs. vSphere 5.0.  Hyper-V to this point has been a great value play for organizations that didn’t have huge management requirements for their virtualized environment.  It’s support for Linux has actually improved a lot as well. But I think it’s unreasonable to think the […]


Corporate Usage Policy – End User initiated encryption and e-discovery

So, if you work for a publically traded company, health care organization, financial services company or government  you may have had to deal with some type of encryption strategy for your mobile devices or removable devices.  There are plenty of enterprise encryption products on the market that can assist with this basic security need.  Also, […]


BYOD is all about delivery

Remember the big push for BYOD laptops?  The theory was that people would get a credit for a laptop device and bring it in to work.  Now the big push is around mobile devices.  End users have voted and Blackberry is out.  iPAD’s, iPhones and Android devices are in.  This makes for a difficult set […]
