This is the purpose of this book. / When learning about infrastructure, it is best to actually touch it, but in the past, you could not learn without physical equipment. But now there is cloud. / In this book, you can learn about infrastructure using Amazon Web Services, a typical cloud service, instead of real machines. It is recommended for young engineers who want to learn about infrastructure as well as app developers who want to relearn about infrastructure. /◆ The major changes in the fourth revised edition are as follows. / 1. Update UI and operation methods / Various operation screens in the AWS Management Console are updated to the latest. / 2. Compatible with Amazon Linux 2023 / In the fourth revised edition, the distribution used is changed to the latest Amazon Linux 2023. In Amazon Linux 2023, the package has been updated and some commands have been changed, such as the installation method has been changed from yum to dnf.

However, in recent years many sites require TLS/SSL, so in the fourth revised edition, you can connect to your own Web server instead of general sites.
