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 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.
