12:00 - Cost Optimization: DPUs, Bookmarks & Best Practices
15:00 - Real Case Studies: Retail & Migration Success Stories
17:00 - Best Practices & Future Trends
💰 Cost Insights:

Glue's pay-per-second pricing vs EMR's 24/7 cluster costs
Hidden cost traps: Over-provisioning DPUs, inefficient crawling
8 weeks → 2 weeks: Glue vs Informatica implementation time
Right-sizing strategy: Start small, monitor, optimize

🛠️ AWS Tools Breakdown:
AWS Glue: Serverless ETL with crawlers, auto-schema detection
EMR: Managed big data platform for massive workloads (100+ DPUs)
Data Pipeline: Workflow orchestration across multiple services
DMS: Database migration with minimal downtime
Batch: Custom containerized processing jobs
🎯 Decision Framework:
Choose Glue if: Python/Spark team, AWS-native, intermittent jobs
Choose EMR if: Massive scale (100 DPUs), ML workloads, dedicated team
Choose Data Pipeline if: Complex orchestration, multiple AWS services
Choose DMS if: Database migration, one-time or continuous replication
🚨 Common Mistakes to Avoid:

Over-provisioning DPUs (right-size based on actual usage)
Running crawlers too frequently
Inefficient ETL scripts that run longer than needed
Not using job bookmarks (reprocessing same data)
Leaving EMR clusters running 24/7 when not needed

💡 Pro Tips:

Use S3 for staging - it's cheaper than compute
Partition your data lake for faster scans
Monitor with CloudWatch & Cost Explorer
Consolidate small jobs to reduce startup overhead
Clean up old metadata from data catalog

🎯 Perfect For:

Data Engineers choosing AWS ETL tools
Cloud Architects designing data pipelines
DevOps teams optimizing data infrastructure costs
Companies evaluating AWS vs traditional ETL tools
Teams migrating from on-premise to cloud

🔗 The Evolution:
ETL is evolving from batch processing to:

Real-time streaming (Kinesis, MSK)
ML model feeding (SageMaker integration)
Data lake management (S3, Athena, Glue Catalog)
