我记忆还停留在 AWS 免费服务器每月 15G 流量的限制，因此还专门写了脚本监控流量，以防破产。结果今天才查到，早在 2021 年 12 月已经提高到每月 100G 流量了，四舍五入就是无限流量！
Data Transfer from AWS Regions to the Internet is now free for up to 100 GB of data per month (up from 1 GB per region). This includes Amazon EC2, Amazon S3, Elastic Load Balancing, and so forth. The expansion does not apply to the AWS GovCloud or AWS China Regions.
从 AWS 区域到互联网的数据传输现在免费提供，每月最多可传输 100 GB 的数据（之前是每个区域 1 GB）。涵盖的服务包括 Amazon EC2、Amazon S3、Elastic Load Balancing 等。此扩展不涵盖 AWS GovCloud 或 AWS 中国区域。
This change is effective December 1, 2021 and takes effect with no effort on your part. As a result of this change, millions of AWS customers worldwide will no longer see a charge for these two categories of data transfer on their monthly AWS bill. Customers who go beyond one or both of these allocations will also see a reduction in their overall data transfer charges.
此更改将于 2021 年 12 月 1 日生效，无需您执行任何操作。由于此次更改，全球数百万 AWS 客户将不会在每月的 AWS 账单中看到这两类数据传输的费用。超出其中一项或两项限额的客户也将看到其总体数据传输费的降低。
