A mobile API running on 5 EC2 instances with Route 53 multi-value routing can’t handle traffic spikes. Should you refactor to serverless, containerize with EKS, add Auto Scaling with Lambda orchestration, or simply front with an ALB? This drill dissects the modernization spectrum for SAP-C02.
When migrating file-heavy applications to AWS, the choice between EFS, EBS, and S3 isn’t just about storage—it’s about understanding shared access patterns, scalability models, and operational overhead. This drill dissects the critical trade-offs.
A high-traffic video platform faces buffering issues during peak hours. This drill analyzes four architectural approaches through FinOps lens, revealing why CDN + object storage beats performance-tuning a shared file system.
A real-world scenario analyzing how to prevent log data loss during EC2 instance termination in Auto Scaling groups. Explores lifecycle hooks, Systems Manager automation, and the critical difference between ABANDON and CONTINUE signals.
Analyze the trade-offs between serverless, container-based, and traditional EC2 architectures for handling millions of hourly requests in a daily flash sale scenario, focusing on latency, scalability, and operational simplicity.
This SAP-C02 scenario explores converting a brittle single-instance application stack into a resilient architecture using Multi-AZ RDS, ElastiCache replication, and Auto Scaling—analyzing the FinOps impact and decision logic behind each component choice.
A professional-level analysis of automated failover strategies for multi-region applications, comparing Route 53 failover policies, Lambda-driven orchestration, and Global Accelerator approaches while balancing RTO requirements against budget constraints.
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.
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.
