After building out our first cloud/LAMP based server and application in early June, we now have “sprawled” to about a dozen servers out there. Just like onsite, it’s just easier to do one app/one server. It’s a natural boundary, even though we logically know we have wasted utilization. In this case though, it is much more palatable. $125 or $250/month is a big improvement over $3000 in hardware and licensing costs.
If your application fits this architecture, it’s hard to beat the economics.
