Perfect choice!
The tariff is suitable for web studios and SEO companies serving many projects created in PHP (WordPress, OpenCart, Zen Cart, Magento, PrestaShop, Ubercart, etc.).
An interactive news portal, a frequently updated or constantly growing e-commerce site that does not yet require a dedicated server - these are the sites that will feel easy with the PHP-SENIOR tariff.
The creation of 30 MySQL databases, the ability to use 150 mailboxes, and 50 GB of disk space will make it easy to manage data and place projects on the network.
Enjoy your time on RealHOST hosting :)
