Netwok - TCP/IP - DNS - TLS - URL - And a lot of RFCs Sysadmin - Unix - Webserver (Nginx, Caddy,...) - Services (Daemons) and logs Programming <Any popular language> Basically there's only three ways to have dynamic content. Either your program is an HTTP server (Java, Node.js,...), it's a script or a program that a server execute (PHP, CGI perl), or it's a program that talks to a web server using FastCGI (and variants). Databases HTTP is stateless, so anything useful should be persisted somehow. Go with SQL (MySql, Postgres,...) and then add whatever you fancy. --- So basically the same thing you needed circa 2010 and earlier. Anything new is something old with a new interface.
