There is a virtual server at Scaleway (4 x86 64bit Cores, 4GB Memory, 100GB SSD Disk), where on Ubuntu 14.04 there is an Apache + PHP + MySQL bundle, which has about a dozen sites with a total attendance of about 1000 hosts per day (MaxSite CMS and WordPress engines ).
Recently I started learning Ruby on Rails and it became necessary to switch from a local machine to a server in order to post something online. Attendance, of course, will be almost zero - I and a few others.
However, I am not sure that RoR and Apache + PHP + MySQL can be installed in parallel, both in terms of performance and in terms of security.
Is it possible to install all this on one virtual server, or is it better to take a new one under RoR?
