I looked at that Rightscale link and I think it shows that comparing a very fast moving area like cloud services is very difficult and results in incomplete features matrix. For the unsophisticated buyer, this can lead to misleading comparisons.
For example, Rightscale has "Event-Driven Compute" (sometimes aka as "serverless computation") in the AWS column (AWS Lambda) but that entry is blank in Google Cloud column. However in February 2016, Google announced Google Cloud Functions which is the equivalent to AWS Lambda.
I'd expect a cloud comparison website to update the features matrix within 1 week of the AWS re:invent conferences, the Google I/O conferences, and any press releases.
As for the other comparison Cloudorado mentioned by another poster, that comparison matrix is missing database services like mapreduce, business intelligence analytics, etc.
Thanks for the feedback. We haven't included Google Cloud Functions yet in the Cloud Comparison tool because it's still in Alpha. We update the information in the Cloud Comparison site quarterly and allow each cloud provider the opportunity to review the material and send us any corrections.
That's is very helpful, although a little outdated (bookmarked nonetheless). AWS now has x1 instances with 128 vCPU's and 1952 GB of ram: https://aws.amazon.com/ec2/instance-types/x1/
On a totally different note, Softlayer has a 100% uptime guarantee! That is surreal if it's actually true.
Yes, tough to cover it all. I believe Azure has a similar "Azure to AWS" comparison. The GCP one is built by folks expertly familiar with AWS and tried to be as factual as possible.
I've previously collected a bunch of Google Cloud customer stories here (not Google PR - customers):
