Amazon WorkSpaces Cost Optimizer v2.3 adds support for existing VPCs and improves billing accuracy and reporting

We recently updated Amazon WorkSpaces Cost Optimizer, a reference implementation that monitors Amazon WorkSpaces usage patterns and automatically updates the billing mode to the most cost-efficient option (hourly or monthly) depending on usage. The Amazon WorkSpaces Cost Optimizer solution saves customers time and money by autonomously managing Amazon WorkSpaces billing so customers can focus on their core business.
