I only send this AWS to use such a convenient, always listen to my friends said, but I have never used, and now use a bit, this is really very good use. For the AWS I really is not very understanding, before always listen to friends talking about knowledge relating to the AWS, but at that time, I always feel I to the AWS, so I never thought to learn, but some time ago, our company. It is used in some of the knowledge, and I was really is do not know how to do, had to learning about, then I use the AWS, I think the AWS really is quite good, I think I should learn some more of this knowledge, so, use can also be convenient.
