Running R in the Cloud with Amazon EC2

Robert Grossman of the Open Data Group has posted a useful set of tips for running R under Amazon's EC2 service. This is a quick and cost-effective way of creating instances of a large number of machines running R. You might want to do this for parallel computing in R when you don't have access to your own cluster, or when using R as the back-end for a web-based application and you're not sure how many servers you'll need (EC2 allows you to dynamically scale the hardware to the demand). 

The Open Data Group has helpfully provided a virtual machine image (called an "AMI") including R (and I believe some of the default AMIs provided by Amazon include R, too). You can also create custom AMIs with REvolution R Enterprise installed, which allows you to take advantage of ParallelR on large EC2 clusters. Creating custom AMI's is pretty easy (especially if you use a provided image as a starting point), and you're probably going to need to create one in any case if you want to use your own packages. (If you do need to create a custom AMI, REvolution's services group can help.)

For those reading this fantastic post but not interested in setting up / maintaining their own EC2 instances, Monkey Analytics (http://www.monkeyanalytics.com) recently added support for R in our cloud based math / science computation web app. We're pretty excited about this (it was the #1 requested user feature post-launch).

Stop by and check us out!

I obtained an academic license from you recently. If I create an AMI for personal use, could I install Revolutions R Enterprise in it? It would be very useful. Being able to run jobs in Amazon EC2, frees us from the limits of our own machines. I have a pretty good desktop, but it doesn't compare with the type of machines you can create in EC2.

Hi Carlos,

If you're using it under the terms of the academic license (i.e. for educational or research use) then you can install it on EC2. Let us know how it goes!

how can we install revolution analytics into amazon ec2 (i know this question is very lame)
