Очистка S3 multipart uploads:

If the complete multipart upload request isn’t sent successfully, Amazon S3 will not assemble the parts and will not create any object. The parts remain in your Amazon S3 account until the multipart upload completes or is aborted, and you pay for the parts that are stored in Amazon S3.

​​Если настраиваете S3 Lifecycle configuration rules для того, чтобы объекты переезжали в Glacier и Glacier Deep Archive, то стоит учесть допиздержки:

▪️ For each object archived to S3 Glacier or S3 Glacier Deep Archive, Amazon S3 uses 8 KB of storage for the name of the object and other metadata. Amazon S3 stores this metadata so that you can get a real-time list of your archived objects by using the Amazon S3 API. For more information, see Get Bucket (List Objects). You are charged Amazon S3 Standard rates for this additional storage.
▪️ For each object that is archived to S3 Glacier or S3 Glacier Deep Archive, Amazon S3 adds 32 KB of storage for index and related metadata. This extra data is necessary to identify and restore your object. You are charged S3 Glacier or S3 Glacier Deep Archive rates for this additional storage.

Это значит, что для мелких файлов - (меньше 10KB для Glacier Deep Archive и 16 для Glacier Deep Archive) стоимость файла на "обычном" S3 получается дешевле (и это не считая ещё траты за Lifecycle Transition requests).

В том числе поэтому S3 Intelligent-Tiering не работает с объектами меньше 128 KB:

The S3 Intelligent-Tiering storage class is suitable for objects larger than 128 KB that you plan to store for at least 30 days. If the size of an object is less than 128 KB, it is not eligible for auto-tiering.

Всегда актуальные пояснения, как формируется (почему так много !?!😀) стоимость трафика в AWS:

▪️ Avoid routing traffic over the internet when connecting to AWS services from within AWS by using VPC endpoints:
▫️ VPC gateway endpoints allow communication to Amazon S3 and Amazon DynamoDB without incurring data transfer charges.
▫️ VPC interface endpoints are available for some AWS services. This type of endpoint incurs hourly service charges and data transfer charges.
▪️ Use Direct Connect instead of the internet for sending data to on-premises networks.
▪️ Traffic that crosses an Availability Zone boundary typically incurs a data transfer charge. Use resources from the local Availability Zone whenever possible.
▪️ Traffic that crosses a Regional boundary will typically incur a data transfer charge. Avoid cross-Region data transfer unless your business case requires it.

In conclusion, we can see the benefit of AWS Graviton2 for both price and performance.
