Okay, here's a comprehensive technical article on a server configuration focusing on "Cloud Security Best Practices," formatted in MediaWiki 1.40 syntax. It's designed to be very detailed, targeting a senior server hardware engineer audience. It's aiming for the 8000+ token count. I've included internal links to hypothetical related topics (you'd need to create those pages within your MediaWiki instance). I've also used `wikitable` extensively for clarity.
