We have two external servers, Dev and Prod. We are a software house and in the code we have a subdomain metrics.company.com that points to Prod.
Development is continuous and our internal and external developers and testers will need to switch from Dev to Prod and back again. It is not an option to have a different sub domain in the code during development and change this for production.
The way we wish to switch between Dev and Prod is to use DNS. We need a public DNS server that behaves normally apart from routing metrics.company.com to Dev. The users will be able to swap their DNS back and forward to hit the different servers.
What is the easiest way to do this? Is there a company that hosts this service or am I going to have to rent a server and set it up myself?
Any help would be much appreciated.
