Talking of deletion...I mistakenly deleted production server, yesterday! I was trying to create some AWS micro instance in Mumbai region which were for some reasons were not accessible. Eventually I had to create a mini instance. So I was terminating all those micro instances and some where by mistake one of my important prod instances got selected and boom.

Though I had an AMI created few months back and it took around 15 mins to get latest code working but yeah I learnt my lesson.

But again I think this is a bad ux from AWS where you can directly terminate any instance without any prompt or warning. I hope they change it some day!
