Deployment Options for Multiple WordPress Sites on a Single Server

1. Install single WordPress instance and turn on the multisite feature

- Easiest way to add multiple sites to existing single WordPress installation
- Built-in feature after WordPress >= v3 - just need to manually edit the wp-config.php file to turn it on
- Subsites or subfolder options provided by default; Ideal for big organizations with many department sites (e.g. department1.myorgonization.org, department2.myorgonization.org)
- If need independent domains (e.g. domain1.com, domain2.com) - WordPress >= v4.5 introduced domain mapping as a native feature. https://wpmudev.com/blog/domain-mapping-wordpress-multisite/
