Download the bill analysis results

The TCO estimation feature analyzes your service bills within the specified time period based on billable items to obtain the specifications, average monthly usage, and average monthly resource consumption for each service. After the analysis is complete, you can download the analysis results in an Excel file to your on-premises device for further analysis.

View the service mapping list

Based on the service specifications and usage, the TCO estimation feature maps the purchased AWS services to Alibaba Cloud services. The TCO estimation feature provides the most cost-effective configurations that can cover your current service usage without compromising the service specifications. You can click View Configurations to view the service mapping list. In the list, you can add, modify, or remove mapping relationships and adjust the resource mapping logic that is predefined in the TCO estimation feature. This allows you to determine Alibaba Cloud service specifications that can meet your business requirements.

Compare services

In terms of cost estimation, the TCO estimation feature calculates the monthly costs of Alibaba Cloud services that are of the same specifications as your purchased AWS services. The TCO estimation feature also provides a comparison between your average monthly costs of using AWS services and the estimated average monthly costs of using Alibaba Cloud services during a specific period. In addition, you can contact your Alibaba Cloud sales manager who can help adjust the price calculation ratio of services in each service category. This further optimizes your costs of using Alibaba Cloud services.
