I need to decide between two servers, one with 2 GB memory and the other with 4 GB. My question is do you think that 2 GB would be enough for a Debian 8 headless server running a Tomcat server with shared process engine taking care of only 2 simple processes and communicating with an external database?
Maybe someone can tell me the expected memory usage for this kind of setup using the linux command “free -m” or something similar.
