Infrastructure Size Planning

What you do is going to depend on your budget. If you’ve got that many people workiung on the site, then I’m going to assume that your hosting budget isn’t the standard “$5 a month is just way to much” argument that comes around on here often. I’d recommend starting off with a mid-level VPS and just monitoring the resources that are being used. Unless you’re re-devloping an existing site, it will take a little bit of itme to get your traffic up to where you want it to be, so server loads can be monitored easily to find out how the server is handleing the load that it’s under. When the load gets to much, move up to a VPS with more resources available. When VPS’s are starting to max out, move to a dedicated server. When that max’s out, move to a cluster. There’s no point starting off huge when you don’t know exact needs. Start reasonable and you will always have the option ov upgrading when you need to.
