AWS Adds Cloud Cost Calculator

Amazon Web Services has added a Cost Explorer toolset for managing spending on its cloud services. Cost Explorer is integrated with the new AWS Billing Console launched in November, and features reporting, analytics, and visualization tools.  The calculator shows current month’s spend and automatically pre-populates the last 4 months of AWS spend, allowing users to visualize AWS costs and start analyzing trends and spending patterns.
