can i use aws or cloud computing to build a website building platform like webs.com or blogspot.com?

I have a web app running on php and mysql.

i have tested on my localhost and i know it works.

if my platform has a url like myplatform.com, and users sign up, they automatically get a website like user1.myplatform.com or user2.myplatform.com, etc.

Akin to blogger, wordpress or webs.com

now if user1 decides to purchase a url from a domain registrar and gets a myurl.com, there is no problem to do that.

now i am using a webhosting dedicated server solution. apparently there is a problem to use shared hosting. Don't quite get why. If an explanation is given, i will be glad to hear it.

now the key question is I am unsure if开发者_StackOverflow i can do the same thing on cloud computing platforms like amazon aws. I posted my question on their forum and customer support.

ZERO reply. Disappointing.

Please advise. Thank you.

Yes. For AWS, you need to use a wildcard A record to point all traffic to *.myplatform.com to your S3 instance's static IP address. Users with their own domain names would need to point something like yourservice.theirdomain.com to the same IP (or a CNAME pointing to www.myplatform.com).

Then, have your application code serve the appropriate content based on the requested hostname.

Yes you can Do the same thing using Amazon AWS. You can have people point to different instances of EC2 or you can point your subdomains to the different homepages/locations on a single EC2 instance. AWS has no such restrictions as mentioned by you.
