And if you manage multiple WordPress websites, try something like InfiniteWP. It takes care of updating core, plugins, and themes. We use it to manage about 23 WordPress websites and being able to update all of your websites with a couple of clicks is an incredible timesaver. We still do manually review everything though (like changelogs, making sure the site still loads and isn't a WSOD, etc.)

We like InfiniteWP because it's free and we can host it ourselves (we've had no need for their paid addons), but there's also other solutions like MainWP, ManageWP, WP Remote, iControlWP, CMS Commander, etc. I think most (if not all) of those are hosted and paid / free trial.

Or let your Linux distribution handle the multi-site Wordpress hosting for you... Thank you Debian !
