+title: 分析 AWS 账单
+---
+
+在本教程中，我们将引导您完成导入 AWS 账单数据并使用 SQL 进行成本分析的过程。您将学习如何将 AWS 账单数据加载到 Databend Cloud 中，查询以找出关键成本驱动因素，并深入了解您的 AWS 使用情况。
+
+AWS 账单数据提供了您的云服务使用情况和相关成本的全面细分，可以直接从 AWS 账单控制台中的 AWS 成本和使用情况报告 (CUR) 服务以 Parquet 格式导出。在本教程中，我们将使用一个 Parquet 格式的示例数据集，可从 [https://datasets.databend.com/aws-billing.parquet](https://datasets.databend.com/aws-billing.parquet) 获取。该数据集遵循 CUR 标准，包括服务名称、使用类型和定价详情等字段。有关完整的架构参考，您可以参考 [AWS 成本和使用情况报告数据字典](https://docs.aws.amazon.com/cur/latest/userguide/data-dictionary.html)。
+
+## 步骤 1：创建目标表
+
+打开一个工作表，创建一个名为 `doc` 的数据库，然后创建一个名为 `aws_billing` 的表：
+
+```sql

+## 步骤 2：加载 AWS 账单数据集
+
+在这一步中，您只需点击几下即可将 AWS 账单数据集加载到 Databend Cloud 中。
+
+1. 在 Databend Cloud 中，选择 **概览** > **加载数据** 以启动数据加载向导。
+
+2. 选择加载数据到 **现有表**，然后选择 **从 URL 加载** 并输入数据集 URL：`https://datasets.databend.com/aws-billing.parquet`。
+
+![alt text](../../../../static/img/documents/tutorials/aws-billing-1.png)
+
+3. 选择您创建的数据库和表，然后选择一个计算集群。
+
+![alt text](../../../../static/img/documents/tutorials/aws-billing-2.png)
+
+4. 点击 **确认** 开始数据加载。
+
+## 步骤 3：使用 SQL 分析成本
+
+现在您的账单数据已经就位，您可以使用 SQL 查询来分析 AWS 账单信息。这一步提供了一些示例，以揭示您的支出并帮助您发现关键见解。
+
+以下查询识别您使用过的最昂贵的服务：
+
+```sql
+SELECT
+    product_servicename AS Service,
+    SUM(line_item_blended_cost) AS Total_Cost
+FROM aws_billing
+WHERE
+    line_item_blended_cost IS NOT NULL
+    AND product_servicename != ''
+GROUP BY product_servicename
+ORDER BY Total_Cost DESC
+LIMIT 25;
+```
+
+以下查询识别最昂贵的 AWS EC2 资源：
+
+```sql
+SELECT
+    line_item_line_item_description,
+    SUM(line_item_blended_cost) AS Total_Cost
+FROM aws_billing
+WHERE
+    product_servicename = 'Amazon Elastic Compute Cloud'
+    AND line_item_blended_cost IS NOT NULL
+    AND identity_line_item_id != ''
+GROUP BY line_item_line_item_description
+ORDER BY Total_Cost DESC
+LIMIT 25;
+```
+
+以下查询识别最昂贵的 S3 存储桶：
+
+```sql
+SELECT
+    line_item_line_item_description,
+    SUM(line_item_blended_cost) AS Cost    
+FROM aws_billing
+WHERE
+    line_item_product_code = 'AmazonS3'
+    AND line_item_line_item_description != ''
+GROUP BY line_item_line_item_description
+ORDER BY Cost DESC
+LIMIT 25;
+```
+
+以下查询识别按混合成本计算的前 25 个最昂贵的区域：
+
+```sql
+SELECT
+    product_region AS Region,
+    SUM(line_item_blended_cost) AS Total_Cost
+FROM aws_billing
+WHERE
+    line_item_blended_cost IS NOT NULL
+    AND product_region IS NOT NULL
+GROUP BY product_region
+ORDER BY Total_Cost DESC
+LIMIT 25;
+```
+
+以下查询将您的成本分类为预留实例和按需实例，以帮助您了解每种类型对您的总支出的贡献：
+
+```sql
+SELECT
+    CASE
+        WHEN reservation_amortized_upfront_cost_for_usage IS NOT NULL THEN 'Reserved Instances'
+        ELSE 'On-Demand'
+    END AS Instance_Type,
+    SUM(line_item_blended_cost) AS Total_Cost
+FROM aws_billing
+WHERE
+    line_item_blended_cost IS NOT NULL
+GROUP BY Instance_Type
+ORDER BY Total_Cost DESC;
+```
