Companies of all sizes and industries have access to an ever-increasing amount of data that is too large for anyone. If you cannot effectively process and analyze all this information, and reveal valuable information based on the data hidden in the noise, then all this information is actually useless. The ETL process extracts information from sources such as Databases, converts files or tables according to Data Warehouse standards, and loads them into the data warehouse.

Are you confused about which tool to use for ETL from your AWS account? Don’t worry this blog will discuss the Amazon ETL process in detail and also tell you about some of the best AWS ETL tools that make the entire process easy and efficient.

What is AWS ETL?

AWS provides a Glue for performing extract, transform, and load (ETL). The product consists of a serverless platform and necessary tools for carrying out data integration. It also helps to modify your data based on your use case.

AWS Glue provides the flexibility to build pipelines either through custom coding or their intuitive UI. You can store data flows and resulting datasets using their data catalog. Administrators can leverage Glue Studio to run and monitor ETL data flows.

Glue Studio also provides a visual job editor and a data flow-style UI. It enables high-level graphical definitions of flows, but the supported transformations are limited. You will need to write code or use SQL for complex modifications like filters, and joins. However, the limitation is that you can use the connectors only for data sources and destinations hosted on AWS. 

You can prepare your data using DataBrew, a very similar but different product from AWS Glue. It offers a bigger library of modifications than Glue. Again, DataBrew connectors are limited, but they can also support conventional databases like Oracle or MySQL that operate on AWS.

To benefit from the combination of both, you should first carry out extraction and loading using Glue must perform to a destination like Redshift. After that,  you can transform your data using DataBrew.

Let’s sum up the limitations of AWS ETL now.

  • The sources supported are only AWS-owned sources, databases operating on AWS, and files from S3 buckets. 
  • Connecting to on-premises data sources is not secure.
  • The tool is not effective when you need to carry out complex transformations that include logic and job execution separated between the two tools. 
  • As both are separate tools, inconsistencies in security policies and vulnerabilities between them could arise.
  • The available features for data governance are limited.

Now, let’s dive deep into the top AWS ETL tools.

Use Cases of AWS ETL Tools

The following are the 5 major uses of AWS ETL Tools:

1) Build Event-driven ETL Pipelines

AWS Glue enables you to prevent any processing delays. It allows you to start your ETL tasks as soon as any new data arrives. So, while you will load new data in your Amazon S3 account, the ETL process will start working in the background.

2) Create a Unified Catalog

The AWS Glue provides a Data Catalog using which you can discover multiple AWS datasets quickly without even shifting any data. Furthermore, Once you successfully catalog the data, you can access it for searching and querying using Amazon Athena, Redshift Spectrum, etc.

3) Create and Monitor ETL Jobs Without Coding

You can seamlessly create and track ETL jobs using AWS Glue Studio. These ETL jobs use a drag-and-drop editor to perform data transformations, while AWS Glue automatically builds a code for the same. Moreover, you can monitor the progress of the ETL jobs with the AWS Glue Studio Task Execution Dashboard.

4) Explore Data with Self-Service Visual Data Preparation

Using the AWS Glue DataBrew, you can experiment with data by directly accessing it from Data Warehouses or Databases, such as Amazon S3, Amazon Redshift, Amazon Aurora, Amazon RDS, etc. It also allows you to choose from 250+ in-built transformations in AWS Glue DataBrew. This way, you can automate various data preparation processes such as anomaly filtering, building formats, and invalid value correction. Once prepared, the data can be used for analytics and machine learning purposes.

5) Build Materialized Views to Combine and Replicate Data

You can create Views using SQL in AWS Glue Elastic Views. These views are beneficial if you wish to combine data stored in multiple data sources and update it regularly. AWS Glue Elastic Views currently supports Amazon DynamoDB as a primary data source but can also integrate with other Amazon products.

Before wrapping up, let’s look into the significance of the tools.

Significance of AWS ETL Tools

AWS ETL Tools refer to the ETL Tools offered by AWS. The following reasons signify the importance of AWS ETL Tools in data migration:

  • When you manually migrate your data, the chances of committing an error due to the dynamism of human nature increase. With the usage of AWS ETL Tools, you will migrate your data with zero data loss.
  • Manually loading your data can be time-consuming, especially when you are dealing with petabytes of data and want to have real-time analysis. AWS ETL Tools help load data in real-time within minutes.
  • The manual data migration process involves a high cost of training personnel to meet the basic standard requirements. AWS ETL Tools provide data migration at a low cost without any help from an expert.
  • AWS ETL Tools ensure data consistency whereas manual methods may lead to inconsistency which can’t be avoided.
  • AWS data integration tools are designed to handle large volumes of data. This makes them efficient for organizations with big data requirements.
  • It is possible to integrate these tools with a wide range of data sources and destinations. Data integration across different environments becomes easier with this. 
  • There are many ETL tools in AWS for data transformation. They contain pre-built transformations and you can also write custom scripts.
