TL;DR

This can be done by building a data pipeline manually, usually a Python script (you can leverage a tool as Apache Airflow for this). This process can take more than a full week of development. Or it can be done in minutes on Airbyte in three easy steps:

1. set up IBM Db2 as a source connector (using Auth, or usually an API key)
2. set up AWS Datalake as a destination connector
3. define which data you want to transfer and how frequently

You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.

This tutorial’s purpose is to show you how.

What is IBM Db2

Specializing in the development and maintenance of Android, iOS, and Web applications, DB2’s AI technology offers fast insights, flexible data management, and secure data movement to businesses globally through its IBM Cloud Pak for Data platform. Companies rely on DB2’s AI-powered insights and secure platform and save money with its multimodal capability, which eliminates the need for unnecessary replication and migration of data. Additionally, DB2 is convenient and will run on any cloud vendor.

What is AWS Datalake

An AWS Data Lake is a centralized repository that allows you to store all your structured and unstructured data at any scale. It is designed to handle massive amounts of data from various sources, such as databases, applications, IoT devices, and more. With AWS Data Lake, you can easily ingest, store, catalog, process, and analyze data using a wide range of AWS services like Amazon S3, Amazon Athena, AWS Glue, and Amazon EMR. This allows you to build data lakes for machine learning, big data analytics, and data warehousing workloads. AWS Data Lake provides a secure, scalable, and cost-effective solution for managing your organization's data.

Prerequisites

1. A IBM Db2 account to transfer your customer data automatically from.
2. A AWS Datalake account.
3. An active Airbyte Cloud account, or you can also choose to use Airbyte Open Source locally. You can follow the instructions to set up Airbyte on your system using docker-compose.

Airbyte is an open-source data integration platform that consolidates and streamlines the process of extracting and loading data from multiple data sources to data warehouses. It offers pre-built connectors, including IBM Db2 and AWS Datalake, for seamless data migration.

When using Airbyte to move data from IBM Db2 to AWS Datalake, it extracts data from IBM Db2 using the source connector, converts it into a format AWS Datalake can ingest using the provided schema, and then loads it into AWS Datalake via the destination connector. This allows businesses to leverage their IBM Db2 data for advanced analytics and insights within AWS Datalake, simplifying the ETL process and saving significant time and resources.

Methods to Move Data From ibm db2 to aws datalake

• Method 1: Connecting ibm db2 to aws datalake using Airbyte.

Method 2: Connecting ibm db2 to aws datalake manually

Moving data from IBM DB2 to an AWS Data Lake without using third-party connectors or integrations involves several steps. Below is a detailed step-by-step guide to accomplish this. Before you begin, ensure you have the necessary permissions and access to both IBM DB2 and AWS services.

Step 1: Export Data from IBM DB2

1. Access DB2 Command Line: Log in to the IBM DB2 database server and open the DB2 command line tool.

2. Connect to the Database: Use the `db2 connect to <DB_NAME>` command to connect to the database from which you want to export data.

3. Export Data:

Determine the tables or data you want to export.

Use the `db2 export to <FILENAME> of del` command to export the data to a delimited file. Example:

     ```

     db2 export to mytable.del of del select * from MYSCHEMA.MYTABLE

     ```

If you have multiple tables, repeat the export command for each table.

4. Compress Exported Data (optional): To reduce the size of the data for transfer, compress the exported files using a tool like `gzip` or `zip`.

Step 2: Transfer Data to Amazon S3

1. Install AWS CLI: If you don't already have the AWS Command Line Interface (CLI) installed, download and install it from the AWS website.

2. Configure AWS CLI:

Run `aws configure` to set up your AWS credentials (Access Key ID, Secret Access Key) and default region.

3. Create an S3 Bucket:

If you haven't already created an S3 bucket for your data lake, use the AWS Management Console or the AWS CLI to create one:

     ```

     aws s3 mb s3://your-datalake-bucket-name

     ```

4. Transfer Files to S3

Use the `aws s3 cp` command to copy the exported data files to the S3 bucket. 

Example:

     ```

     aws s3 cp mytable.del.gz s3://your-datalake-bucket-name/db2-export/

     ```

Repeat for all exported data files.

Step 3: Prepare AWS Data Lake

1. Set Up AWS Glue Catalog:

Create a database in AWS Glue Data Catalog to organize your data. This can be done through the AWS Glue Console or using the AWS CLI.

2. Define Data Schema:

Define the table schema in Glue Data Catalog that matches the structure of the data you exported from DB2.

3. Create IAM Roles:

Create the necessary IAM roles with permissions to access S3 and AWS Glue services.

Step 4: Load Data into AWS Data Lake

1. Use AWS Glue

• Create an ETL job in AWS Glue to load data from the S3 bucket into your data lake.
• Choose the previously created IAM role for the job.
• Define the source as your S3 bucket and the target as the AWS Glue Data Catalog database.
• Map the source columns to the target columns as per the schema defined.

2. Run the ETL Job:

Execute the AWS Glue job to transform and load the data into the AWS Data Lake.

Step 5: Verify Data Integrity

1. Check the Data:

• Once the ETL job is complete, verify that the data has been correctly loaded into the AWS Data Lake.
• Use services like Amazon Athena to query the data and ensure its integrity.

2. Clean Up

 If necessary, remove any temporary files from S3 to avoid incurring unnecessary costs.

Step 6: Set Up Data Lake Security

1. Configure Access Control:

Use AWS Identity and Access Management (IAM) to set up the appropriate permissions for users and applications to access the data lake.

2. Enable Encryption:

Enable encryption on your S3 bucket to protect your data at rest.

3. Monitor Access

Set up logging and monitoring through AWS CloudTrail and Amazon CloudWatch to keep an eye on access and usage of your data lake.

Use Cases to transfer your IBM Db2 data to AWS Datalake

Integrating data from IBM Db2 to AWS Datalake provides several benefits. Here are a few use cases:

1. Advanced Analytics: AWS Datalake’s powerful data processing capabilities enable you to perform complex queries and data analysis on your IBM Db2 data, extracting insights that wouldn't be possible within IBM Db2 alone.
2. Data Consolidation: If you're using multiple other sources along with IBM Db2, syncing to AWS Datalake allows you to centralize your data for a holistic view of your operations, and to set up a change data capture process so you never have any discrepancies in your data again.
3. Historical Data Analysis: IBM Db2 has limits on historical data. Syncing data to AWS Datalake allows for long-term data retention and analysis of historical trends over time.
4. Data Security and Compliance: AWS Datalake provides robust data security features. Syncing IBM Db2 data to AWS Datalake ensures your data is secured and allows for advanced data governance and compliance management.
