I have 3 ASP.NET web sites and 3 Ruby on Rails ones. I'm planning them to be hosted on a VPS hosting. Suppouse each of them would have the attendance of 1 thousand people per day.
Now I'm hesitating about the VPS hosting. Can I host them (ASP.NET web sites and 3 Ruby on Rails ones) side by side? Or should I use and buy 2 different hosting: first one is for ASP.NET web sites and second one for RoR web sites?
How much power of VPS do I choose to host them? And how much does it cost approximately?
I'm planning to pay not more than 25$ per month. If I use heroku and appharbor would they host all of them (3 and 3) and how much would it cost?
