Currently i am trying to achive that a user sign up on my website after that Enter their AWS Access Key and Secret key.
After AWS Key verification, there is a form for asking the user Select Region > Select Number of Visitors, Enter Domain Name, SSL Checkbox & done.
After this i am trying to Launch EC2 Instance on selected region, and instance family is depend on the Number of visitors.

and for myself, i am using BOTO3 to automate this.
How can we do this for user because we need to change AWS Access & Secret keys
Do we need to save keys with different profile name?

One more thing, How can i add Domain name because currently my bash script is installing wordpress on the public IP, Can we also change Domain name?
