Introduction
A sizing is an approximation of the hardware resources required to support a specific software implementation, in this case SmartHCM. This document sets main foundations towards sizing the hardware required to run SmartHCM. SmartHCM has experience managing internal product installations on the basic instance types provided by Amazon EC2: m1.small, c1.medium and m1.large. We know the results that these instances can provide us, both in terms of performance and scalability. At the same time SmartHCM embraces experience of our customers running product on physical hardware and also using virtualization. In addition to this SmartHCM does performance tests for particular product usage scenarios. These three inputs has allowed us to write a table comparing the hardware resources needed to support particular number of concurrent users.
