Features	Benefits
Reports	Directly compare and contrast the pricing outcomes of competing public cloud providers based on your specific needs.
Server-to-Cloud Mapping	Easily bridge the gap between a physical server and the cloud world. CloudSizer is powered by RPE2, the industry-leading server performance estimate from IDEAS. CloudSizer can match physical servers with cloud instances quickly and easily.
Variable Workload Modeling	A key feature of public cloud services is the variability in pricing based on usage, whereby you only pay for what you use, in contrast to the fixed costs of a physical server. The CloudSizer algorithm takes the utilization and duty cycles of physical servers into account when analyzing the costs of various cloud solutions, giving you a more accurate assessment of your potential cloud costs.
Instance Profiling	By normalizing the often disparate per-instance pricing models, CloudSizer ensures you are making like-for-like pricing comparisons.
Currency Conversions	CloudSizer normalizes all costs to a target currency, making apples-to-apples pricing comparisons quick and easy.
