Atomic is intended to be used as a host OS and uses RHEL, CentOS, or Fedora as a base typically. And the installer ISO is that large precisely because it bundles hardware, language, and all kinds of other support.
However, if you'd like to craft your own minimal Atomic host, you can.
Making minimal containers is pretty easy, though, since yum/dnf lets you create execution trees that contain only what's needed for an application to run (as others have mentioned).
So, really, doing micro-services on RHEL/CentOS/Fedora hosts is pretty easy.
