Now have the AWS also do what server, and a waste of equipment and a waste of money, we now the system is often the server also online over a hundred people, want to bring up is particularly good, but the equipment price is super expensive, but also daily maintenance, tired to death. So it is better to AWS some, as long as the network can be used, and can be online at the same time one hundred or two hundred people are not a problem. We have asked some partners, they are basically using AWS, because this is also in order to protect the security of data, so this is really very important, and now our company is ready to use aws.
