Cousin AWS in a company work, I also don’t understand how to AWS, I asked him what the AWS is doing what, he gave me an example is the image, so I immediately understand what their company is doing things, sometimes we will don’t know how to some very professional thing, I think it would take some examples, so we will be very intuitive to know exactly what is going on, give me all my friends say, now you really want to have a good harvest, if you want to go do these things, in fact, I think I have felt that way, because I know I have a lot of things to learn.
