Problem
Partner ingestion systems need a boundary that accepts data safely, absorbs bursts, rejects malformed payloads, and preserves enough raw input to replay downstream failures.
Design
- PrivateLink keeps producer traffic off the public internet.
- A private API endpoint or Network Load Balancer receives partner submissions.
- Lambda validates schema, identity, size, and idempotency keys.
- Kinesis buffers accepted events and allows multiple consumers.
- S3 stores immutable raw payloads with KMS encryption and lifecycle rules.
- DLQs capture failures with enough metadata for replay.
Well-Architected lens
- Reliability: backpressure through streams, replay from S3, and isolated failure queues.
- Security: private connectivity, KMS encryption, least-privilege producers, and input validation.
- Performance efficiency: stream shard sizing follows ingestion volume rather than guesswork.
- Cost optimization: retention windows, lifecycle rules, and right-sized shard counts.
Why it is not live here
This pattern is valuable when external producers and private connectivity exist. Running it without real partner traffic would mostly create idle infrastructure and synthetic complexity.
