How much need resources to do so in the context of "processes/RAM/disk"
Only the test - set, launch monitor load and choose to add or not resources.
Because the sites are different, as stuffing, and in attendance, and VDS are the same is not the case, and given the fact that in many cases VDS resources are provided dynamically and are not guaranteed at all fun.
What about security? Firewall enough or some AntiVir better?
Need a normal iron firewall that enables access only to the necessary ports WinServer, regular firewall also configure. Any online software - web server antivirus is something unimaginable. On the other hand if you have a bulk load of files - well it would be nice for any antivirus scanner to check them, but this is obviously not to server security concerns, and the quality of services to users.
As easier to manage? Maybe some webpanel free for Windows is
Lebanese should not be used on Linux machines and on windows. It is not clear what is not satisfied with the standard GUI?
If you have a server without a GUI - is there a power shell, and the snap connection to the remote server.
