Rackspace has announced that they are getting into the Windows virtual machine bizness. I’ve been waiting for this market to heat up, and have competition drive down some prices.
RAM is everything, and the service providers usually make this the main spec you pay for. In virtual environments, it’s even more important since disk I/O tends to be especially slow – you want to keep as much in RAM as possible.
A quick price comparison. Let’s say you want a 4GB instance. Rackspace seems to be offering it at around $230/month (24 hours x 30 days x $0.32 per hour).
At GoGrid (my current vendor), paying by the hour would net out to around $547/month. With a pre-paid plan, for $199/month you can get the equivalent of 3.5G of RAM (they calculate in GB-hours). Extrapolating to 4G would put us at approximately $227/month – so that’s very close to Rackspace.
(To date I’ve been paying around $99/month for 1G at GoGrid).
Over at Amazon, their large Windows instance offers 7.5G for around $345/month. If we apply that pricing to 4G, it comes out to $184. Not bad! But since they don’t offer a 4G instance, you’d effectively be buying two of them to get that price. Their small instance (1.7G) would cost the equivalent of around $204 if you extrapolated out to 4G.
MaximumASP is offering a 2G plan for $198/month or the equivalent of $396 for 4G. (They don’t offer such a plan but I am using the number for apples-to-apples.) That seems uncompetitive based on the above.
SoftLayer offers a 4G plan for $219/month ($199 for the instance + $20 for Windows). That’s in line with the others.
I encourage you to check my math by visiting these sites. Another important caveat is that these plans vary in terms of included storage and bandwidth (and manageability), so it’s not always a like-for-like comparison.
Overall, it looks to be considerably cheaper than when I first started playing with virtual hosts a year ago.
Virtual servers are not for everyone – in my limited experience I find that performance can be inconsistent. And slow disk I/O will limit the applications where you’d want to go virtual.
And, in the Windows world, horizontal scaling is still not that common, so the attraction of being able to spin up a lot of servers on demand might not mean much to you.
On the upside, you really do get yourself out of the hardware business by taking a virtual approach. You can spin up new machines and kill ‘em just as quickly. And you keep capital expenses minimal.

Update 12 Nov: Kevin Babcock points out VPSLand, which offers a 3GB plan for $78, the equivalent of $104/month for 4G. Wow, that’s cheap.
SosftSys offers a 2GB plan for $125, so that’s the equivalent of $250/mo.
I’ve used VPSLand and SoftSys Hosting for my VPS needs. You can get a Windows 2008 instance with 1GB RAM from VPSLand starting at $34/mo or from SoftSys starting at $55/mo. If you prefer Windows Server 2003, the price is a bit lower. Having used VPSLand for 2 years now, I must say they provide tremendous service and support. I recently bought a second plan with SoftSys b/c at the time VPSLand was not offering Window Server 2008. They’ve been great too. After I spend a bit more time with them I’ll be making the decision to either go with them completely or stick with VPSLand.
GoGrid looks pretty nifty, with fun features like free load balancing, but I wish they offered image snapshots. (It looks like SoftSys does). Even better would be the ability to export/import Hyper-V images. Maybe that’s too much to ask for though
It’s also worth noting whether the virtualization is done via Virtuozzo or Hyper-V. I don’t know how much it matters, but there are difference between the platforms.
Looks like GoGrid has their own image format, which you can configure and save: http://www.gogrid.com/cloud-hosting/custom-cloud-server-images.php
I don’t think they are using Hyper-V, perhaps it’s Virtuozzo or Xen.
I have to express my thanks to this writer for bailing me out of such a trouble. Right after looking out through the search engines and obtaining notions which are not powerful, I believed my entire life was done. Existing without the presence of strategies to the problems you’ve sorted out by means of your guide is a crucial case, and the kind that would have in a negative way affected my career if I had not noticed your web page. Your personal talents and kindness in playing with all areas was helpful. I don’t know what I would’ve done if I had not come upon such a thing like this. I am able to at this point look ahead to my future. Thanks for your time very much for your specialized and results-oriented help. I won’t think twice to refer your web blog to any person who wants and needs support about this problem.
