The German 'iX magazine fuer professionelle IT' is pretty good, but it also has devops, the whole stack from networking, data storage, compute, cloud, development en ops. I bought one on holiday. It's nice to browse through pages for a change. A fixed A4 keeping your attention on 1 page. https://www.heise.de/select/ix

I think it's only in German, but perhaps the AI can auto-translate the pdf's.
