• Set custom time intervals and granularities (daily, monthly) for detailed analysis.
  
• Filter and group data by various dimensions such as service, region, or tag.
  
• Build custom applications using the Cost Explorer API for advanced analytics.
  

Recent updates include the ability to create custom billing views using Cost Allocation Tags and accounts, allowing stakeholders to focus on relevant cost and usage information. 

AWS Budgets

AWS Budgets allows you to set custom budgets and receive alerts when your costs or usage exceed defined thresholds. Key features include:

• Creating and managing budgets for cost, usage, RI utilization, and coverage.
