    1. I think you have a mistake in the definition of blue/green deployment. In blue/green deployment you don't take any hosts from production, In blue/green deployment you provision a whole new set of hosts and shift the production traffic from the old (blue) environment to the new (green). This way you don't lose capacity and can rollback easily if needed.

    2. How likely a tester can jump into DevOps or how easy or difficult to grasp this a tester. I saw a question here, are you from Dev side or Ops side. I am from neither. I am into testing.. But would like to change my career into something promising for future. Would any of you please reply?
