I'm developing a SaaS service and will be managing payments as a merchant for customers, and since we'll be using multipe payment processors depending on users location, amount and other factors so its important to store card details.

I did some research and from what I understood all you need is a PCI compliant host (VPS, Dedicated or Private Cloud) and get it validated and certified through some provider like TrustWave etc... Is that correct or am I missing something?

Also, would be great if you could suggest a few (not necessasrily cheap, but affordable) PCI compliant hosts.

Many thanks
