SQS Lambda Integration - The Idempotency vs. Architecture Trade-off | SAA-C03

A photo processing startup faces duplicate email notifications due to SQS standard queue behavior triggering Lambda multiple times. This drill explores visibility timeout tuning, queue type selection, and deletion timing strategies to achieve exactly-once processing with minimal operational overhead.

IoT Migration Trade-offs—Serverless vs Containers | SAP-C02

This SAP-C02 scenario explores migrating a legacy IoT telemetry platform to AWS. The decision centers on serverless-first architecture (IoT Core + Lambda + DocumentDB) versus container-based approaches, with FinOps impact quantified across data ingestion, storage, and reporting layers.

SQS Buffering for Resilient Event Ingestion | SAP-C02

When third-party dependencies fail in high-throughput IoT pipelines, the solution isn’t just adding a queue—it’s architecting for graceful degradation. This drill examines the SQS decoupling pattern, DLQ strategies, and why API Gateway direct integrations beat Lambda intermediaries for resilience.

Auto-Healing Network Inspection Route Decisions | SAP-C02

When network appliances fail in auto-scaling groups, static routes become stale. This SAP-C02 scenario explores the orchestration pattern combining custom metrics, event-driven automation, and Lambda-based route reconciliation—a real-world decision between operational complexity and infrastructure reliability.
