Cost Archiver
Updated over a week ago

Finout provides you with a simple way to manage long-term storage of cost data.

You can configure Finout to archive data in an AWS S3 bucket that you own — allowing you to store cloud spending data from your company’s various cost centers in one structured, easily accessible format.

Setting Up Cost Archiver

In order to output the cost data, Finout requires write permissions to an S3 bucket. For this purpose, please either create a new bucket or a new folder within the existing S3 bucket that’s used for your AWS CUR files.

Bucket Permissions

Note: If there are currently no policies applied on the bucket, please use the following policy:

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "AWS": "{FinoutRole}" }, "Action": [ "s3:GetObject", "s3:PutObject", "s3:PutObjectAcl", "s3:ListMultipartUploadParts" ], "Resource": "arn:aws:s3:::{DestinationBucketName}/*" } ] }

Note: If there are already statements in the bucket’s policy, please add the following to the statements array:

{ "Effect": "Allow", "Principal": { "AWS": "{FinoutRole}" }, "Action": [ "s3:GetObject", "s3:PutObject", "s3:PutObjectAcl", "s3:ListMultipartUploadParts" ], "Resource": "arn:aws:s3:::{DestinationBucketName}/*" }

Note: If you wish to limit the write permissions to a specific folder within the bucket, please update the resource portion as follows:

"Resource": "arn:aws:s3:::{DestinationBucketName}/{SomeFolder}/*"

Archived Cost Data

Cost data will be updated once a day in the following structure: bucket/archiver_name/v1/yyyymmdd.json.gz

Cost data can be added retroactively by request, and there is no limitation in terms of the archived data size.
