Despite the early warnings Citrix has made a direct hit at VMWorld 2009, announcing enterprise-proven XenServer will now be free. The news seems to have been well received by IT shops looking for ways to save in the tough economic climate as well as by virtualization consultants expanding the options they can offer customers. Michael Goldstein, VP at LAN Associates, a VMware, Microsoft and Citrix Reseller that specializes in IT solutions for the legal industry said “ This move by Citrix is going to really shake things up. Unless the client is totally committed to VMware, we can now also offer credible virtualization options based on XenServer that make the ROI really compelling and probably get projects approved faster “ VMware as well as some skeptics in the industry immediately speculated about a shell game of features that were shuffled around and whether the off...

Amazon Virtual Private Cloud Opens Doors for Citrix Customers

The Amazon Web Services (AWS) announcement of the Virtual Private Cloud (VPC) offering has just made Cloud Computing more attractive to the enterprise. Most companies I talk with are interested in the “Cloud”, but beyond a few SaaS apps and perhaps some dev/test they are not ready for any big change to their corporate IT infrastructure. On the other hand many of those same companies are currently or projected to be capacity limited in their own data center based on space or power limitations. Many companies will opt to move or expand into a Co-lo (Co-location) facility which prov... (more)

Cloud Computing Economics, Part Two

Chris Fleck's Blog As described in part 1 of this blog series, the cloud is not the answer for every enterprise or every workload. This is true based on the current economics even without considering additional factors like security, control and SLA's. On the other hand the economics do point out a major cloud advantage when it comes to short term or variable workloads. (Pointed out by Michael Keen and Billy Marshall as well). Perhaps this is not very surprising to many, but it does help to look at the numbers to put it in perspective. The largest Intrinsic cost advantage of the ... (more)

Amazon EC2 Reserved Pricing Changes the Equation

Ulitzer Cloud Computing Blog Things are changing fast in the world of Cloud Computing, however one question remains the same. Will it save me money and how much? To follow up on a previous post on Cloud Economics Part One, I looked at a fairly simple example of 5 Servers for a dev/test environment and identified the incremental costs of buying 5 servers and running them on premise or a Colo and then compared that to Amazon EC2. The analysis did not include many variables such as real estate costs and labor savings which may or may not apply to the particular situation. The result... (more)

Cloud Computing Economics - Amazon EC2 vs Terremark v Cloud Express

The recent announcement of the Terremark Cloud offering has raised significant attention especially because of the competitive pricing and EC2 like features of elastic capacity and hourly charges with no commitment. On the surface the Terremark entry price of $0.036 per hour seems very low compared to Amazon EC2 at $0.10 but it's worth picking a few examples to provide a more apples to apples comparison. Not included in the comparison is the difference in storage costs which can be small or very significant depending on the circumstance. Amazon provides up to 160 GB of instance... (more)
