Cloud migration: Move data to AWS, Azure, Snowflake
System integration: Connect ERP, CRM, and other applications
Data quality: Cleanse and standardize enterprise data
Master data management: Create golden records from multiple systems
Talend vs Alternatives
vs Informatica: Informatica more mature, Talend more affordable
vs Apache NiFi: NiFi better for streaming, Talend better for batch
vs Pentaho: Similar tools, Talend stronger cloud integration
Unique Strengths
Code generation: Creates deployable applications, not just workflows
Open source core: Free powerful ETL platform
Component library: 900+ pre-built connectors
Complete platform: ETL, data quality, MDM in one solution
Bottom line: Solid enterprise ETL platform with unique open source offering. Good for organizations needing both data integration and quality features. Code generation approach is different from competitors. Open Studio is genuinely free and useful. Commercial version expensive but comprehensive. Better than building custom ETL from scratch.
