Assessment and dynamic provisioning of computing resources for multi-tiered application

A computer-implemented method comprising:

• determining, by a computing device, a topology of a multi-tiered application;
• determining, by the computing device, a modeled setting for nodes of the multi-tiered application based on the topology of the multi-tiered application to determine an amount of memory needed by the multi-tiered application at the nodes;
• adjusting, by the computing device, an allocation of the memory to the multi-tiered application based on an actual usage of the memory by the multi-tiered application and the modeled setting;
• and
• proactively monitoring and assessing, by the computing device, the multi-tiered application against a real-time load and a demand within the multi-tiered application using the modeled setting by performing data collection on the actual memory usage and comparing the actual memory usage against historical data and projected demands.
