Hi,
First of all thank you for answer.
The link I've shown is just a example of how an user "try" or "buy" a product of those companies. What I wanna you observe, based on simple form, they start a new instance of their solution automatically. There's no one coping an war to a
wildfly or such kind of thing. More then that, their web site already do a desired subdomain for the customer. Basically, What I wanna know is what are the technologies or infrastructure behind of it?
Thanks.
