That's not entirely unfair. The important thing though is that these particular "steroids" enable a new way of systems management. > This seems like it would create a lot of redundancy on a > standalone system.

For example, CoreOS uses a Fedora-based container for systems management.

This is an orthogonal issue — you can certainly do all of this in your own data center if you like. (And I expect a lot of Fedora users will be using containers in this way.) But, speaking as a former sysadmin who has Seen Things, a well-managed public cloud enviroment (e.g. Amazon, GCE, Azure, Digital Ocean, etc.) is in a practical sense much less of a data security risk than running a local server room at any scale. -- Matthew Miller <mat...@fedoraproject.org> Fedora Project Leader _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org
