如何在AWS Cost Explorer中单独监控EC2的EBS存储成本？

Hey there! Glad to hear you're finding the EC2 daily cost view in Cost Explorer useful—totally agree that's a smooth experience. Let's walk through exactly how you can pull out EBS storage costs to compare your different allocation strategies.

Step 1: Navigate to the Flexible Cost and Usage View #

• Log into your AWS Management Console, head to the Billing & Cost Management section, and open Cost Explorer.
• Skip the default EC2-focused dashboard and go to Cost and Usage from the left sidebar—this view gives you the flexibility to drill into specific service costs like EBS.

Step 2: Filter to EBS-Only Costs #

• At the top of the page, use the Filter dropdown:
  1. Select Service from the filter options.
  2. Choose Elastic Block Store (EBS) from the list of services. This will immediately narrow down all costs to just EBS-related charges.
• For even more detail (like separating general-purpose vs provisioned IOPS volumes), add a second filter: select Usage Type and pick the specific EBS usage categories you want to compare (e.g., EBS:VolumeUsage.gp2, EBS:VolumeUsage.gp3, EBS:VolumeUsage.io1).

Step 3: Group Costs to Compare Your Storage Strategies #

• Use the Group by dropdown to segment costs in a way that aligns with your comparison goals:
  • If you want to compare costs by volume type, group by Usage Type.
  • If you’ve tagged your EBS volumes with labels for different allocation strategies (e.g., StorageStrategy:PerformanceFirst, StorageStrategy:CostOptimized), group by Tag and select your custom tag key.
  • To match the daily granularity you get with EC2, set the Time range to your desired period and set the granularity to Daily (you’ll find this in the time range dropdown’s advanced options).

Step 4: Save Your Custom Report #

• Once you’ve got the view configured perfectly, click Save report at the top right corner. Name it something descriptive like "EBS Storage Cost by Allocation Strategy" so you can pull it up instantly later without redoing all the filters.

Bonus: Set Up Ongoing Monitoring with Budgets #

• If you want to track these costs over time and get alerts when spending deviates from your expected strategy, head to Budgets (also under Billing & Cost Management). Create a budget focused on EBS costs, set threshold alerts, and you’ll get notified via email or SNS if costs go over (or under) your targets.
