Thanks a lot for your consideration, but i am updating/creating configurable products programatically so what should be my area code ??

I recommend to use \Magento\Framework\App\Area::AREA_ADMINHTML for all the product updating tasks.
It was defenitely important in Magento 1.x, and could be important in Magento 2 too.
