A Note on Classic Application Architecture

Classic Applications are usually comprised of three core components. The Web Application, a Document Storage System, and a Database System. In the Classic Application Architecture model these components are distributed across one or more servers.

When resources become maxed out on these servers new hardware must be added to meet the demand. This is called Scaling up because you scale up your hardware’s specification to meet the demands of your application’s requirements and will probably lead to big servers, slow servers, or high maintenance costs, so it’s not very flexible or efficient from a resource management perspective.

But this is fine actually because this resource management model is perfectly well suited to clients who can accurately predict their usage of an application and have adequate resources to hand.
