Achieving true end-to-end encryption requires certificates on both the load balancer AND backend instances. This drill explores why ACM alone isn’t enough and how to balance security requirements with operational complexity.
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.
A foundational analysis of ALB redirect rules vs. alternative approaches to enforce HTTPS traffic, examining why native load balancer features trump complex network-layer solutions for this common security requirement.
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.
