12.15.09 Costs Between Proprietary And Open Source Products Narrows In The Cloud  By
Savio Rodrigues
After my previous post "Cloud to boost proprietary software use?", Tim Bray questioned whether the pricing comparison of "WebSphere/SUSE vs. JBoss/RHEL on EC2 was a transient anomaly". JBoss' Rich Sharples commented that I was comparing apples and oranges. That was not my intention. I simply picked the only two application server Amazon Machine Images (AMIs) that I could easily find pricing for. And in retrospect, my intention was not to compare proprietary versus open source pricing in the cloud. But rather to compare the price differential of proprietary versus open source products in the cloud versus on-premise. Let me try again with Windows versus Linux. Specifically, I looked at the price of Windows Server 2008 R2 versus Red Hat Enterprise Linux (RHEL) on-premise and on Amazon's Elastic Compute Cloud (EC2). I wanted to evaluate how, if at all, the Windows price premium differs on-premise versus in the Amazon cloud. One can argue that "you need 2 Windows servers to do the work of a RHEL server." Such an argument has no impact on this analysis. If you do in fact need 2, or a higher number of Windows servers per RHEL server, this ratio would hold equally well on-premise or on Amazon EC2. Here's what I found: On-premise license: Windows Server 2008 R2 Datacenter Edition: $2,999 Windows Server 2008 R2 Enterprise with 25 Client Access Licenses: $3,999 Red Hat Enterprise Linux Premium Subscription for 1 year: $1,299 Windows price premium: 130% to 208% [See UPDATE below] Amazon EC2 license on Standard-Small AMI: Windows Server 2008 R2: $0.12/hr Red Hat Enterprise Linux: $0.21/hr plus $19/month per customer Windows Price premium: -43% [See UPDATE below] If you're surprised that the Windows Server AMI is 43 percent less expensive per hour than the RHEL AMI raise you hand [See UPDATE below]. Maybe you think I've missed some important or potentially hidden costs for the Windows AMI. I may have. I'm by no means an operating systems licensing expert. However, it's difficult to accept that these costs would add up to Windows being 130% to 208% premium priced versus RHEL on EC2. Even if I've missed a pricing component that doubles the "true" price of a Windows AMI in a production setting, that would roughly put Windows and RHEL at par in terms of EC2 per hour pricing. That's a far cry from the 130 percent to 208 percent premium for Windows over RHEL in an on-premise environment. Hat tip to William Vambenepe for astutely pointing out that the license cost differential between proprietary and open source products narrows in the cloud. [UPDATE: 2009-12-11 @ 5:45p EST -- PLEASE Read] Based on public & private comments here is some new information for readers: 1] The version of RHEL on EC2 is supported by Red Hat at the Red Hat "Basic Subscription Web support" level. This includes 2 business day response, and unlimited incidents. Red Hat charges $349/year for this license. As previously mentioned the equivalent RHEL AMI (with an equivalent level of support) is $0.21/hr plus $19/month. Continue reading this article.
