In the Site Software section of each hosting Control Panel (cPanel) applications such as WordPress, Joomla etc. can be installed in seconds with a few clicks of the mouse.
The installations also include the setup of the MySQL database. Not only that but when newer versions of your installations become available you can be automatically reminded via email to upgrade them. Upgrading an installation can also be done with a few clicks of a mouse.
You will never have to worry again about your applications being up to date the latest security patches, bug fixes and features!
