I have a CentOS 7 with Apache2 and a Drupal application with a MariaDB database. The application must be available for 2000 users and sometimes about 1800 users will be using it simultaneously. I was thinking about having two VM one for the application and one for it's database. If the users will only have a very basic use of the applications only read and download very few files. How much vCPU, RAM and disk space do you think I need? Thank you very much
