Summary: Cloud computing represent a fundamental change in software costs and scale. Amazon’s Web Services are a cloud-type resource available now.
As developers deep-down we have a map of our computing terrain. Our maps help us make decisions about the viability of ideas and how we implement them. Crucial elements of our map is the cost and scale of the computing resources we use.
Cloud computing is the art of delivering computer resources when they are needed usually priced per hour of use. Cloud Computing changes our computing map, not by adding new hills or rivers, but buy shifting the underlying tectonic plates of our computing terrain.
For instance Amazon’s web-services change our cost and availability constraints. Linux servers now come at, a very low-cost, 10 cents/hour and with no limit on the number of servers that can be used. Amazon’s web-servcies are an excellent example of how a factor-of-ten cost reduction produces a game-changing service.
Take a look; cost-out your latest design using Amazon’s web-services. Then compare the cost of using Amazon’s services versus your current solution. Write me a comment; did you get a factor-of-ten cost reduction?
