AWS end-to-end data engineering pipeline ingests CSV and JSON data from Orders, Customers, and Products sources into S3 Raw Bucket, triggered by Lambda on file arrival. AWS Glue ETL job cleans, deduplicates, and joins data, writing Parquet files to S3 Processed Bucket while populating Glue Data Catalog with schema and partitions. Amazon Athena queries partitioned data and feeds Amazon Redshift analytics warehouse and Amazon QuickSight dashboards for real-time visualization. CloudWatch and SNS provide comprehensive logging, monitoring, and alerting across the entire pipeline. This architecture demonstrates serverless scalability, cost optimization through S3 partitioning, and separation of concerns between ingestion, transformation, and analytics layers.
