AWS messaging — SQS queues, SNS topics, EventBridge event bus, Kinesis data streams.
Stub — full skill pending. Core patterns documented below.
| Service | Pattern | Use case |
|---|---|---|
| SQS | Queue (pull) | Decoupled async processing; Lambda trigger; dead-letter queue |
| SNS | Topic (push/fan-out) | Broadcast to multiple subscribers; email, SMS, SQS, Lambda |
| EventBridge | Event bus | AWS service events + custom events; rules → targets |
| Kinesis | Stream | High-throughput real-time data; analytics pipelines; ordered records |
# Create standard queue
aws sqs create-queue --queue-name my-queue --region af-south-1
# Create DLQ
aws sqs create-queue --queue-name my-queue-dlq --region af-south-1
# Wire Lambda trigger (from Lambda console or CDK)
aws lambda create-event-source-mapping \
--function-name my-function \
--event-source-arn arn:aws:sqs:af-south-1:123456789012:my-queue \
--batch-size 10 \
--maximum-batching-window-in-seconds 5# Route GuardDuty finding to Lambda
aws events put-rule \
--name guardduty-to-lambda \
--event-pattern '{"source":["aws.guardduty"]}' \
--region af-south-1
