AWS Entity Resolution review
A flexible AWS service for rule-based, ML-powered, and fuzzy record matching.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AWS Entity Resolution is a cloud service for matching, linking, deduplicating, and enhancing related customer, product, business, or healthcare records. It is aimed at developers, analysts, and organizations working with distributed structured data across applications, channels, and data stores. Workflows can be managed through the AWS Management Console, CLI, or API, with results sent to Amazon S3 or Amazon Connect Customer Profiles. The service is available through web and API access.
Matching depth is a central strength. Teams can configure rule-based workflows or use preconfigured machine-learning matching with confidence scores. Advanced fuzzy matching supports Levenshtein Distance, Cosine Similarity, and Soundex, while automatic incremental processing supports rule-based workflows. Near real-time matching and match-ID generation are available, along with near real-time lookup through the Get Match ID API. Data-provider matching and record enhancement add another route for organizations that need external data workflows.
The published usage plans charge per 1,000 records processed. The Rule-based or ML-powered plan costs $0.25 per 1,000 records processed, while the Data service provider plan costs $0.10 per 1,000 records processed. Data-provider matching also requires a provider subscription or license, and the AWS Free Tier is not available. AWS Entity Resolution is a strong fit for teams already working with Amazon S3, AWS Glue, AWS Clean Rooms, Amazon Connect Customer Profiles, Amazon Ads, CloudTrail, or CloudFormation. Organizations seeking a non-AWS-centered workflow or predictable flat-rate pricing may prefer an alternative.
