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.
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.
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.
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.
A financial analytics firm wastes 40% of EC2 costs on idle time. This drill analyzes four architectures—Lambda, SQS+ASG, containerized polling, and ECS Fargate—to identify the optimal event-driven solution balancing FinOps impact and operational overhead.
A mid-size enterprise plans to migrate a critical Lambda + Aurora application from an existing AWS account to a new AWS account. This drill explores options balancing downtime, security, and FinOps impact.
When Lambda’s 15-minute maximum timeout becomes a hard constraint, this drill explores the serverless-to-container migration decision framework, comparing ECS Fargate, Step Functions parallelization, and infrastructure modernization strategies through a FinOps lens.
A financial analytics startup needs to process variable file uploads from S3 with minimal operational overhead. This drill compares serverless Lambda, EC2-based processing, EMR clusters, and Kinesis streaming—revealing why event-driven architectures trump traditional compute for unpredictable workloads.
This SAP-C02 scenario examines how to generate recurring Lambda cost optimization reports with minimal development effort. The key decision: leverage managed AWS Compute Optimizer APIs versus building custom CloudWatch metric extraction logic.
An e-commerce startup must ensure customer order data is not lost during database maintenance windows. We analyze options to decouple data ingestion from the database and maintain data durability.
