Introduction
Every successful Machine Learning (ML) project starts with one critical ingredient: quality data. Yet, preparing data is often the messiest, most time-consuming, and underestimated step in the ML lifecycle. Businesses spend up to 80% of their ML project time just cleaning, transforming, and organizing datasets before they can even begin training models.
At DigitalCloudAdvisor (DCA), we’ve seen this challenge firsthand while helping SMBs and enterprises adopt AI on AWS. That’s why tools like Amazon SageMaker Data Wrangler and AWS Glue are game changers—they simplify and automate data preparation, turning a complex task into an efficient and repeatable process.
Why Data Preparation Matters
High-quality data is the foundation of accurate ML models. Without it, even the most advanced algorithms won’t deliver reliable insights. Poorly prepared data leads to:
- Biased predictions
- Inaccurate forecasts
- Wasted time and money
- Missed business opportunities
Investing in proper data preparation means cleaner features, faster development, and more trustworthy results.
Amazon SageMaker Data Wrangler: No-Code Data Prep for ML
SageMaker Data Wrangler is designed to reduce the time it takes to prepare data for ML from weeks to just minutes. With an intuitive, no-code interface, teams can:
- Connect data sources directly from S3, Athena, Redshift, or databases.
- Explore data visually to identify gaps, duplicates, and outliers.
- Clean and transform datasets with over 300 built-in transformations.
- Feature engineer quickly to extract valuable signals for ML models.
- Export pipelines directly into SageMaker for training, ensuring consistency from prep to deployment.
👉 In practice: A retail company can use Data Wrangler to merge sales data with customer demographics, quickly identify trends, and feed a clean dataset into SageMaker Forecast for accurate demand planning.
AWS Glue: Serverless Data Integration at Scale
Where SageMaker Data Wrangler shines at interactive exploration, AWS Glue excels at scalable, automated ETL (Extract, Transform, Load). It’s the backbone for enterprises managing large volumes of raw, messy data.
Key features of AWS Glue include:
- Serverless ETL – No infrastructure to manage, scale up or down on demand.
- Glue Data Catalog – A central metadata repository to keep track of all your datasets.
- Automated schema discovery – Quickly identify structure and relationships across your data.
- Job automation – Schedule recurring transformations and keep data pipelines up to date.
👉 In practice: A financial services firm can use Glue to pull data from multiple CRMs, clean it, catalog it, and make it ready for ML analysis—reducing manual work and ensuring compliance with regulations.
SageMaker Data Wrangler + AWS Glue: Better Together
When used together, these two services create a seamless data preparation pipeline:
- AWS Glue ingests, catalogs, and organizes large datasets at scale.
- SageMaker Data Wrangler provides an interactive interface for analysts and data scientists to clean, transform, and engineer features.
- The output flows directly into SageMaker Studio for ML training and deployment.
This combination empowers businesses of any size to transform messy, siloed data into a single source of truth ready for ML.
