Modernizing a legacy master-worker application requires eliminating single points of failure. This drill explores why queue-based decoupling with demand-driven autoscaling beats scheduled scaling and monolithic coordination patterns.
When faced with extreme message volume spikes (100K msg/sec) and dozens of independent consumers, choosing between SNS+SQS fan-out, Kinesis streams, and autoscaling patterns determines both scalability and cost efficiency.
A professional-level analysis of implementing secure cross-account S3 access patterns, examining the dual-permission model and common security pitfalls that cost enterprises millions in data breach remediation.
A 70TB NFS migration scenario that tests your understanding of AWS data transfer services, bandwidth constraints, and the critical trade-off between migration speed and network utilization. Learn why physical data transfer devices trump internet-based solutions at scale.
How to architect serverless metadata delivery for legacy IoT devices: CloudFront Functions vs Lambda@Edge vs API Gateway - a FinOps and performance trade-off analysis for AWS SAP-C02.
When scaling a stateful web application across multiple Availability Zones, local EBS storage creates data silos. This drill explores the architectural decision between EBS replication, session affinity, and shared file systems like Amazon EFS.
This SAP-C02 drill examines how to architect for both database read scalability (Aurora Replicas) and application session consistency (ALB sticky sessions) when migrating stateful workloads—a common pitfall that distinguishes professional-level thinking from associate-level shortcuts.
A professional-level analysis of AWS Organizations SCP architecture during M&A integration - balancing temporary flexibility with long-term governance stability.
Designing multi-region API resilience requires balancing DNS routing strategies, regional Lambda deployments, and DynamoDB replication. This drill exposes the critical difference between edge-optimized endpoints and regional API Gateway deployments for disaster recovery.
