title: Opening multiple appium server Instances on same machine
body: <p>Can I start 2 appium server instances on my machine at the same time so that I can execute my test script simultaneously on 2 different devices connected to the machine? 
  Actually what I'm trying is to run my test script on 2 devices connected to same windows machine. For this I am using TestNG to pass the Android Driver url to start session. This url will be dynamic as 2 devices will be using 2 Appium server instances. Can I create 2 instances of Appium server at same time? If so then can I use code to create those instances as I don't want to use GUI to start it.</p>
