Platform as a Service & Cloud Computing

In the last year, I've heard a lot of opinions and noise around SaaS, PaaS, and Cloud Computing. And the marketing is not helping.
The original intention of my previous post "A Bird's Eye View of Cloud Computing, SaaS and PaaS" was to visualize THE categories. However, I think there's a general need of simple high-level criteria.
What
We know "Now everything is on line"......Let's be naive:
- SaaS = Software
- Cloud Computing = Hardware
- PaaS = Software for Developers / Operations
We can refer to "cloud computing" as running on line as a general concept. But, talking about hard stuff, a company is providing a software service or a hardware service, so it's SaaS or Cloud Computing. Examples: SuccessFactors vs Amazon EC2.
Who
Based on these simple concepts, you can know if you need Software or Hardware. If you are looking for a SaaS, you have to find the right package for your needs (features vs monthly pricing). From SMB packages to full enterprise services.
If you are looking for hardware (and the associated network connectivity and human resources to keep the service running), you have to choose between the minimum hosting package to world-wide load balanced servers. Cloud Computing "by nature" is a very high load service. For any regular (small and medium) website, you can easily use a simple hosting or collocated server.
PaaS is a tough call for developers, it changes the standard development model to easy the process to publish and operate a software service.
