Documentation

Note: This article covers AWS S3 Destination setup process. This guide doesn’t cover the DataPrep setup for AWS S3.

You can learn how to extract data from AWS S3 Data source here.

Description

‍AWS S3 is an object storage service that offers companies industry-leading scalability, data availability, security, and performance. This means that companies of all sizes can use it to store and protect data for a range of use cases, no matter the amount of data available.

Setup guide

Follow our setup guide to connect AWS S3 to Improvado.

Choose an encryption option

Choose a server-side encryption option:

• SSE-S3 (recommended) - server-side encryption with AWS S3 managed keys. Learn more.
• SSE-KMS - server-side encryption with AWS KMS keys. Learn more.
  Make sure to give the required permissions for the AWS-managed key.
• SSE-KMS with customer-managed key - server-side encryption with customer-managed AWS KMS keys. Learn more.
  Make sure to give the required permissions for an encryption key.
• No storage encryption - not recommended unless the AWS S3 bucket has default encryption.

Important: Make sure to provide your AWS S3 bucket information by following our guide.

‍

8. Provide your AWS S3 bucket information to Improvado (Option #3)

Provide your AWS S3 bucket information to Improvado (Option #3)

Provide our Support Team or your CSM with the following information:

• Bucket Name
• AWS Region

Our team will create specific users to load data and provide support.

Option #4 (Provide access via Cross-Account AWS IAM Role Chaining)

This option uses the chain of AWS IAM roles: Improvado role assumes the customer’s role, which has access to S3 and (optionally) to KMS.

Supported encryption types:

• SSE-S3 - server-side encryption with AWS S3 managed keys.
• SSE-KMS - server-side encryption with AWS-managed KMS keys.
• SSE-KMS with customer-managed key - server-side encryption with customer-managed AWS KMS keys.
• No storage encryption - not recommended unless the AWS S3 bucket has default encryption.

Implementation steps:

1. You notify our Support or your CSM.
2. ~Improvado creates a specific AWS IAM role for you and sends you the role ARN.
3. ~The Improvado role ARN will have such format: ```arn:aws:iam::<Improvado AWS account id>:role/uls_managed/file_sender_<some string>_<some number>```.
4. You create an AWS S3 bucket and KMS Key (if needed).
5. You create a role in the AWS IAM and set its Trust policy and Permissions.
6. ~The role should have such a Trust policy (Assume role policy):

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "Improvado role ARN"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}

7. ~~replace the ```Improvado role ARN``` with the value provided by Improvado.
8. ~The role should have read and write permissions on the S3 bucket and (optionally if you use KMS encryption) usage permissions on the KMS key:

{
    "Statement": [
        {
            "Sid": "RWPolicy",
            "Action": [
                "s3:GetObject*",
                "s3:DeleteObject",
                "s3:PutObject*"
            ],
            "Effect": "Allow",
            "Resource": "arn:aws:s3:::your-bucket-name/*"
        },
        {
            "Sid": "ListPolicy",
            "Action": [
                "s3:ListBucket"
            ],
            "Effect": "Allow",
            "Resource": "arn:aws:s3:::your-bucket-name"
        },
        {
            "Sid": "OptionalKMSUsagePolicy",
            "Action": [
                "kms:Encrypt",
                "kms:Decrypt",
                "kms:ReEncrypt*",
                "kms:GenerateDataKey*",
                "kms:DescribeKey"
            ],
            "Effect": "Allow",
            "Resource": "arn:aws:kms:region:123456789:key/111aa2bb-2c33dd"
        }
    ],
    "Version": "2012-10-17"
}

9. ~~replace ```your-bucket-name``` with your S3 bucket name.
10. ~~you can allow to put/get/delete objects in some prefix (path or directory) of the S3 bucket instead of the whole S3 bucket. In this case the Resource format in the ```"RWPolicy"``` will be ```"arn:aws:s3:::your-bucket-name/path_prefix/*"```.
11. ~~replace the ```region``` with your KMS key Region (i.e. ```us-east-1```).
12. ~~replace the 123456789 with your AWS Account ID.
13. ~~replace the 111aa2bb-2c33dd with your KMS Key ID.
14. You notify Improvado with your role ARN. Improvado makes configuration adjustments.
15. You create a new connection on the Destinations page, and set up data loads.
16. ~choose the Connection Option “Provide access via Cross-Account AWS IAM Role Chaining”.
17. ~provide your role ARN in the “Assume Role ARN” field.

Additional information

Folder

Possible parameters:

```/{{workspace_id}}/{{workspace_title}}/{{data_source}}/{{data_table_title}}/{{report_type}}/{{filename}}/{{account}}/{{YYYY}}/{{MM}}/{{DD}}```

• ```{{workspace_id}}``` and ```{{workspace_title}}``` are optional parameters that provide additional information about the workspace used for a destination connection
• ```{{data_source}}``` is a data provider, integration, connector.
• ```{{data_table_title}}``` is an object that contains all extraction orders with the same granularity (dimensional schema).
• ```{{report_type}}``` is a set of such fields as metrics, properties, dimensions, etc.
• ```{{account}}``` - is an optional parameter that allows you to to add specific account for the data load.
• ~ You must enable Use load by account field to add this parameter to the File name.
• If you use ```/{{YYYY}}/{{MM}}/{{DD}}``` settings, the data will be added to folders daily. Each new record will not delete the previous one, even for data that contains no date.
  • You can use ```DD_today``` instead of ```DD``` to use today’s date in the folder name. E.g., ```/{{workspace_id}}/{{workspace_title}}/{{data_source}}/{{report_type}}/{{YYYY}}/{{MM}}/{{DD_today}}``` will be resolved to ```/ws1/main_group/ds1/rt1/2024/06/18```

‍Data structure of S3 storage by Improvado. You can create a request to the Support Team to add support for different folder structures in a bucket.

File format

Possible formats:

• csv
• csv+gzip
• json
• json+gzip
• parquet
• avro

File name

Possible parameters:

```{{filename}}-{{account}}-{{YYYY}}-{{MM}}-{{DD}}```

• ```{{filename}}``` - is the same as destination table name
• ```{{account}}``` - is an optional parameter that allows you to to add specific account for the data load.
• ~You must enable Use load by account field to add this parameter to the File name

IMPORTANT: you cannot use ```{{DD}}``` for partition by month

• ```{{filename}}-{{YYYY}}-{{MM}}-{{DD}}``` – for partition by day
  • You can use ```DD_today``` instead of ```DD```, to use today’s date in the final file name. E.g., ```{{ filename }}-{{ YYYY }}{{ MM }}{{ DD_today }}T{{ H }}{{ M }}{{ S }}``` will be resolved to ```some_name-2024-06-20T121517```
• ```{{filename}}-{{YYYY}}-{{MM}}``` – for partition by month

Also, you can use “_” instead of “-” or do not use any symbols at all, for example:

• ```{{filename}}_{{YYYY}}-{{MM}}-{{DD}}```
• ```{{filename}}{{YYYY}}{{MM}}{{DD}}```

Separator

Possible delimiters that can separate data in your file:

• comma
• semicolon
• tab

Partition by

Possible ways of splitting data:

• Day
• Month
