• With CloudWatch, you can create billing alerts that notify you when your usage of your services exceeds thresholds that you define.

AWS Free Tier

• When you create an AWS account, you’re automatically signed up for the free tier for 12 months.

• To help you stay within the limits, you can track your free tier usage and set a billing alarm with AWS Budgets to notify you if you start incurring charges.

AWS Cost and Usage Reports

• The AWS Cost and Usage report provides information about your use of AWS resources and estimated costs for that usage.
• The AWS Cost and Usage report is a .csv file or a collection of .csv files that is stored in an S3 bucket. Anyone who has permissions to access the specified S3 bucket can see your billing report files.
• You can use the Cost and Usage report to track your Reserved Instance Utilization, charges, and allocations.

  • Hourly if you want your items in the report to be aggregated by the hour.
  • Daily if you want your items in the report to be aggregated by the day.
  • Monthly if you want your items in the report to be aggregated by month.
• Report can be automatically uploaded into AWS Redshift and/or AWS QuickSight for analysis.

AWS Cost Explorer

• Cost Explorer includes a default report that helps you visualize the costs and usage associated with your TOP FIVE cost-accruing AWS services, and gives you a detailed breakdown on all services in the table view.
• You can view data for up to the last 12 months, forecast how much you’re likely to spend for the next three months, and get recommendations on what Reserved Instances to purchase.
• Cost Explorer must be enabled before it can be used. You can enable it only if you’re the owner of the AWS account and you signed in to the account with your root credentials.

• If you’re the owner of a management account in an organization, enabling Cost Explorer enables Cost Explorer for all of the organization accounts. You can’t grant or deny access individually.
