So, I have a few domains currently, and I am going to start developing them, slowly. Currently, you can say each of them has 0 traffic, however, I hope in the not too distant future, turn these sites into blogs and start to monetize them. My question is, if I am going to build them on a single VPS, what type of resources should I start with (ball park). At this point lets say I have 3-5 domains. Can a 4gb 2 CPU vps handle this currently easily (3-5 wordpress instances) with little to no traffic? Do I need to go beefier or is this overkill?
Just looking for some feedback.
