About Client
1Place is a technology-driven organization focused on leveraging data to enhance decision-making, reporting, and operational intelligence. The company manages a growing data ecosystem comprising multiple data sources, analytics tools, and business applications. AWS offers glue as a fully managed etl service
To address scalability challenges and improve data automation, 1Place collaborated with Peritos Solutions, an AWS Advanced Consulting Partner, to design and implement a serverless data platform using AWS Glue. The goal was to replace manual data workflows with a secure, automated ETL framework that ensures accuracy, consistency, and governance.
Project Background – Data Modernization through AWS Glue ETL service
1Place data operations were previously dependent on traditional ETL tools that lacked automation and flexibility. These manual processes caused data silos, inconsistent data quality, and delayed reporting.
Peritos Solutions proposed an AWS Glue-based serverless ETL framework to transform 1Place data landscape. The solution automated schema detection, data cataloging, and transformation pipelines while ensuring end-to-end visibility through AWS CloudWatch and centralized governance.
This transformation allowed 1Place to manage large-scale data workloads with minimal operational overhead while maintaining compliance, traceability, and cost efficiency.
Objectives of the Engagement
- Establish a serverless, automated data integration framework using AWS Glue ETL service
- Replace legacy ETL pipelines with scalable and efficient Glue jobs
- Implement centralized metadata management using AWS Glue Data Catalog.
- Enable cross-service data integration with S3, RDS, and Redshift.
- Ensure security, governance, and compliance through IAM, encryption, and monitoring.

Business Problem Addressed
1Place existing ETL infrastructure was time-intensive and not scalable. Manual intervention led to delays, higher costs, and inconsistent data quality.
Proposed AWS Glue-Based Solution
Peritos Solutions implemented an end-to-end AWS Glue solution integrating multiple data sources and automating data transformation and cataloging. Using Glue Crawlers, Jobs, and Workflows, the entire ETL process became event-driven, reducing human intervention and operational latency.
Key Benefits
- Serverless data integration with zero infrastructure management.
- Automated data discovery and schema management.
- Faster and more reliable data transformation pipelines.
- Improved data governance through centralized metadata.
- Seamless analytics enablement through Athena and QuickSight integration.

Architecture Overview
The architecture consisted of:
- Data Sources: S3, RDS, and on-premises data via secure connectors.
- ETL Layer: AWS Glue Crawlers, Jobs, and Workflows.
- Data Catalog: Centralized schema and metadata management.
- Analytics Layer: Athena and QuickSight for visualization.
- Monitoring & Logging: CloudWatch for logs, metrics, and alerts.
Technology Stack
- AWS Services: Glue, S3, RDS, Redshift, CloudWatch, Lambda, Secrets Manager, IAM.
- Security: KMS encryption, MFA-enabled IAM roles, and cross-account logging.
- Automation: CI/CD pipelines with AWS CodePipeline and CodeBuild.
AWS Glue Components Implemented
- Glue Crawlers: Automated schema discovery for S3 and RDS datasets.
- Glue Jobs: ETL scripts built using PySpark to clean, normalize, and enrich data.
- Glue Workflows: Orchestration for dependency-based execution.
- Data Catalog: Managed metadata, table schemas, and data lineage.
- Triggers: Event-driven execution using CloudWatch and EventBridge.
Security and Compliance
- IAM policies applied with least privilege.
- Glue roles restricted to authorized services only.
- KMS encryption applied for data at rest and in transit.
- CloudTrail enabled for audit trails and compliance verification.
Runbook and Troubleshooting Scenarios
Routine Operational Tasks
- Daily monitoring of Glue job metrics and DPU utilization.
- Reviewing failed job logs and rerunning based on SLA thresholds.
- Verifying Data Catalog updates and schema integrity.
- Checking Glue job triggers and workflow dependencies.
Common Troubleshooting Scenarios
- Job Failures Due to Schema Drift: Re-run Glue Crawler, refresh Data Catalog, and update ETL script mapping.
- Performance Degradation: Tune Spark configurations and increase DPU allocation.
- Connection Errors: Validate IAM permissions, VPC configurations, and network paths.
- Data Quality Issues: Use Glue dynamic frames and AWS Deequ for validation.
