I think myself is very outdated, now a lot of things I didn’t understand, that day in the office I heard colleagues say this AWS, I did not know what is the AWS, I also feel shy to ask, I’m afraid of people joke me later and friends together. They also said the AWS, I asked them what is the AWS, friends know me, for himself without knowledge is never to learn, so they gave me some knowledge about the AWS, then I think, this AWS knowledge really is a very good use and even if I don’t work, then maybe in a way to be able to use it, so I think of it, I still have time to learn about the AWS knowledge, learn some of their own or have anyway. Good.
