Here's a brief explanation of each of the service items you mentioned:

RDS - Transfer:
This refers to the data transfer between your Amazon RDS instance and other AWS services or the internet.

RDS - Compute:
This is the cost associated with the compute resources (CPU and memory) allocated to your Amazon RDS instance.

RDS - Charged Backup Usage:
This includes the charges for storing automated or manual backups of your RDS instances.

RDS - I/O:
This covers the input/output operations performed by your RDS instances. It includes both read and write operations to your database.

RDS - Storage:
This represents the cost of storing your database files on Amazon RDS.

RDS - GP2 Storage:
This is specifically related to the cost of using General Purpose (GP2) storage for your RDS instances. GP2 is a type of Amazon EBS storage.

RDS - Data Transfer:
Similar to "RDS - Transfer," this involves the cost of data transfer associated with your RDS instances.

RDS - Other:
This category may include additional miscellaneous costs related to your RDS instances that don't fall into the other specified categories.

  • Can you please share reference documentation for the information shared?

  • Also, in the cost report, for RDS-Compute, I do not get all the RDS Clusters and instance details present in the account, it only lists Operation specific to CreateDBInstance, the instances created on that specific period. Can you explain the service items based on how AWS uses it to calculate cost?

Hi, While there may not be specific documentation that explains each of these service items in your AWS billing breakdown, I can provide you with general explanations for each of them based on common AWS billing components related to Aurora RDS and PL/SQL instances:

RDS - Transfer:
    This could refer to the data transfer between different AWS regions or availability zones.

RDS - Compute:
    This likely represents the cost associated with the computational resources (CPU, memory) utilized by your Aurora RDS instances.

RDS - Charged Backup Usage:
    This refers to the cost incurred for storing automated backups and manual snapshots of your Aurora RDS cluster.

RDS - I/O:
    This might represent the Input/Output operations performed by your Aurora RDS instances. It includes the cost associated with read and write operations.

RDS - Storage:
    This covers the cost of storing the data in your Aurora RDS instances.

RDS - GP2 Storage:
    This specifically refers to the cost of General Purpose (GP2) storage, which is the default storage type for Amazon RDS.

RDS - Data Transfer:
    This could represent the cost of data transferred out of your Aurora RDS instances to the internet or other AWS services.

RDS - Other:
    This is a generic category that may include miscellaneous costs related to your Aurora RDS instances that don't fall into the more specific categories listed.

RDS - Charged Backup Usage (duplicated):
    The duplication of this item might be an error or it could represent a more granular breakdown of backup-related charges.

  • Thank you. However, the answer is similar to what @holem mentioned.

    This does not answer my follow up question - "Also, in the cost report, for RDS-Compute, I do not get all the RDS Clusters and instance details present in the account, it only lists Operation specific to CreateDBInstance, the instances created on that specific period. Can you explain the service items based on how AWS uses it to calculate cost?"
