Hosting in the cloud(s)

As of today my websites are hosted fromout a cloud environment at OVH. I was interested in what way cloud computing could offer me cost savings and flexibility. I will test the current environment for a few weeks to see if it can offer the same performance- and uptime characteristics as my local VMWare ESXi 3.5 environment.

As a pay for every hour i will play around with  amount of internal memory. Please notify me if my site gets too slow 🙂
