I am totally new to AWS. There was a posting here ~ a year ago making claims about setting up a CentOS image on AWS. I have created a free AWS account and am looking at the available images. None are named CentOS. There is a Redhat Enterprise Linux 8 and Amazon's own Linux and SUSE, Ubuntu, but I don't find CentOS. This is a learning endeavor. I was thinking to first set up a BIND slave for my domain. Then move on to a http image, then work with MariaDB. All to see what I can do with AWS that is familiar to what I do on my own servers. Any pointers greatly appreciated.
