Overview
Event producers publish ordered records to Amazon Kinesis. Lambda validates and enriches those records before Data Firehose batches them into a partitioned S3 analytics lake. Athena provides serverless SQL access, and QuickSight turns query results into dashboards and scheduled reports.
Components
- Kinesis and Lambda: Kinesis buffers ordered events while Lambda validates and enriches records.
- Data Firehose and S3: Firehose batches data into a partitioned analytics lake with durable retention.
- Athena and QuickSight: Athena exposes serverless SQL results that QuickSight turns into dashboards.
Streaming Data Flow
- Producers publish events to Kinesis using workload-appropriate partition keys.
- Lambda transforms records and forwards clean events to Data Firehose.
- Firehose stores batches in S3, where Athena and QuickSight serve analytical views.
Customize First
- Set shard capacity and backpressure alarms from measured event volume.
- Add a dead-letter destination for records that cannot be transformed.
- Define partition projection and data-retention policies before dashboard adoption grows.
Design rationale
Decisions that shape this architecture
Absorb bursts before processing
Kinesis gives producers a durable buffer and lets processing capacity recover from temporary spikes without dropping accepted records.
Batch writes into the analytics lake
Data Firehose combines small streaming records into more query-efficient S3 objects and can organize delivery by time or dynamic partition keys.
Keep historical data independently queryable
S3 remains the long-term record, so dashboard changes do not require the ingestion stream to replay every event through a permanent database.
Before production
Operational checks
Alarm on iterator age, throttling, transformation errors, and failed Firehose delivery.
Validate partition keys against hot-shard and ordering requirements.
Track schema versions and quarantine records that cannot be parsed safely.
Review S3 object size, partition count, Athena scan volume, and dashboard freshness.
Scope and tradeoffs
What this diagram does not solve
Athena is not a sub-second streaming database
Use a purpose-built operational analytics store when applications need continuously updated low-latency queries rather than lake-oriented analysis.
Exactly-once business effects require application design
Retries can deliver a record more than once. Consumers and downstream aggregations should use stable event IDs and idempotent writes.
Common questions
Frequently asked questions
Why place Lambda before Data Firehose?
Lambda can validate and enrich records before Firehose batches them for storage, keeping malformed or incomplete events out of trusted analytical partitions.
How quickly can dashboards update?
Freshness depends on stream processing, Firehose buffering, S3 partition discovery, Athena queries, and QuickSight refresh settings. Define the required delay before tuning each stage.
Can this architecture support replay?
Kinesis retains a bounded stream history, while S3 provides durable long-term records. Reprocessing jobs should read the appropriate source based on the replay window.
