I am a moderator on Web Applications, and I would like to address the points of this Web Apps Meta question to a wider audience, because we get more than a handful of questions on these topics that have been originally posted on SU and which are either migrated or re-asked on our site.
I'd like to open a discussion as to how EC2 and AWS questions should be treated in the future.
From the tag wiki for amazon-ec2 (On SU)
Amazon EC2 (Elastic Compute Cloud) is a web service that allows users to rent virtual computing capacity on which they can run their applications. Because EC2 is a web service, questions should be asked at http://webapps.stackexchange.com/https://webapps.stackexchange.com/ as they are off-topic here.
From the tag wiki for amazon-web-services (On SU)
off topic. Questions regarding this should be asked at [webapps.se].
Around probably four years ago, our focus began to shift away from any software that was hosted "in the cloud" to those that specifically behaved like applications. From our help center:
Using Gmail, Facebook, Twitter, Google, or any other website which behaves like an application
While I am not an expert in EC2/AWS, it seems to me that these questions fall under the hosting umbrella rather than something that pertains to (as I tend to emphasize when interpreting our close reasons) end-users of applications such as Facebook and Gmail. We certainly would welcome questions about the UI of any front end that Amazon would provide, but I think that it's time to decide where the vast majority of the hosting-related questions belong.
These questions are certainly IT related, but they don't always have a ready home, and I think we should definitely determine how to divvy them up or distribute them in the first place.
At a bare minimum, I think this slightly misleading information should probably be removed from the Tag Wikis for the time being.
