Separate hosting for WordPress admin, is that possible?

Hi all,

I’ve been working on a new amazon environment for one of my project, and the traffic to it is been growing and growing, and more people is accessing and I’m trying to prevent this using an auto-scaled, self healing environment. For this purpose I’m using the beanstalk service to be able to create the environment once, and deploy the code through a GIT repository. Also, I want to implement the CDN Cloudfront to serve all static files images, js, css, etc…

Everything was going fine, but I got the brilliant idea to try to separate the admin side to a different host, let’s say admin.mysite.com

My problem is that I don’t know if that is possible, I have read several forums and no one has achieved such configuration.

Do anyone know if that’s possible? I mean not to have the admin side public and respond only to admin.mysite.com host? this way we can centralize all admin operation on a single instance and let the auto scaling work on the other(s) server(s) as the traffic comes in.

Please let me know your suggestions.

Thanks in advance!
