For the past few years I've been a Bluehost / LAMP site developer, but now i intend to switch to Digital Ocean to get a competitively-priced VPS i can use to pursue other technologies (nginx, Scheme & Clojure development).
I've a couple of laptops i'm using to test my current LAMP / Joomla! / JQuery -based domain & subdomains on to make sure I can get them to work on Digital Ocean.
QUESTION: how would i setup DNS / IP resolution on the test / development environment?
Would I create a "closed" environment using my real domain name and local DNS to "mimic" the Digital Ocean VPS?
Would i create a "ficitious" domain on the test laptop(s), get my current site up and running then "translate" the working config to the real domain?
What caveats do i need to pay attention to (DNS, nginx, CGI)?
