Master AWS analytics! Kinesis, Athena, Glue, EMR, Redshift, OpenSearch & QuickSight - the whole data pipeline. Punchy 35-min format!
🆕 INTERACTIVE FORMAT
🎯 PULSE CHECKS - Real pauses to test yourself
⚠️ TRAP SPOTLIGHTS - Exam traps highlighted live
💡 MEMORY HOOKS - Vivid analogies that stick
🔄 THE PIPELINE MODEL
Collect → Store → Catalog/Transform → Query/Process → Warehouse → Search → Visualize
🌊 KINESIS (real-time streaming)
DATA STREAMS:
• Custom real-time processing (your own consumer code)
• Retention up to 365 days + REPLAY capability
• Provisioned (shards) or On-Demand mode
• Data ordering by partition ID
DATA FIREHOSE:
• Fully managed delivery to S3/Redshift/OpenSearch
• Near real-time (buffered)
• NO storage, NO replay
• Lambda transformations, Parquet conversion
Hook: Data Streams = conveyor belt with your workers. Firehose = fire hose into a tank.
🔍 AMAZON ATHENA
• Serverless SQL queries on S3 data
• Built on Presto, standard SQL
• $5 per TB SCANNED (not stored!)
• Cost savings: Parquet/ORC, compression, partitioning
• Federated Query across other sources
• EXAM TIP: "serverless SQL on S3" = Athena
Hook: Librarian who reads books in place.
🧴 AWS GLUE
• Serverless ETL (extract, transform, load)
• Convert CSV → Parquet for Athena
• Glue Data Catalog = central metadata store
• Data Crawler auto-discovers schema
• Athena/Redshift Spectrum/EMR read from catalog
Hook: Sticky layer that connects & indexes everything.
🏭 AMAZON EMR (Elastic MapReduce)
• Managed Hadoop/Spark clusters
• Hundreds of EC2 instances
• Bundled: Spark, HBase, Presto, Flink
• Nodes: Master, Core, Task (Spot!)
• Use for: LARGE-SCALE processing
Hook: Renting an industrial factory floor.
🏢 AMAZON REDSHIFT
• OLAP data warehouse (not OLTP!)
• Based on PostgreSQL, columnar storage
• 10x performance, scales to PBs
• Leader node + compute nodes
• Snapshots + cross-region copy for DR
• Redshift Spectrum queries S3 directly
vs Athena: Redshift = heavy/constant queries. Athena = ad-hoc on S3.
Hook: Purpose-built analytics warehouse.
🔎 AMAZON OPENSEARCH
• Search ANY field (even partial matches)
• Successor to Elasticsearch
• Complements another database
• Ingests from Firehose, IoT, CloudWatch Logs
• Classic pattern: DynamoDB + Streams + Lambda + OpenSearch
Hook: Smart search box on your filing cabinet.
📈 AMAZON QUICKSIGHT
• Serverless business intelligence
• Interactive dashboards
• SPICE in-memory engine
• Integrates: Athena, Redshift, S3, RDS, OpenSearch
• Per-session pricing
Hook: The presentation room at the end.
⚠️ TOP EXAM TRAPS
1. Data Streams (replay/custom) vs Firehose (managed delivery)
2. "Serverless SQL on S3" = Athena
3. Athena (ad-hoc S3) vs Redshift (heavy warehouse)
4. EMR only for Hadoop/Spark/large-scale
5. Glue = ETL; Glue Data Catalog = metadata
6. OpenSearch = search any field
7. QuickSight = dashboards/BI
8. OLTP (RDS/DynamoDB) vs OLAP (Redshift)
9. Athena cost = Parquet + compress + partition
10. Firehose delivers to S3/Redshift/OpenSearch
📊 DECISION FRAMEWORK
• Streaming + replay? → Data Streams
• Managed streaming delivery? → Firehose
• Serverless SQL on S3? → Athena
• ETL + cataloging? → Glue
• Hadoop/Spark? → EMR
• Data warehouse? → Redshift
• Search any field? → OpenSearch
• Dashboards? → QuickSight
