When developers can’t perform basic operations despite having IAM permissions, understanding the SCP hierarchy model becomes critical. This drill analyzes the fundamental principle of AWS Organizations permission boundaries.
A high-level summary: When migrating a web application to AWS that depends on a third-party API with strict IP whitelisting (single CIDR block), the correct solution is to use BYOIP (Bring Your Own IP) with NAT Gateway, not ALB or Global Accelerator. This drill deconstructs why outbound traffic routing—not inbound traffic acceleration—is the critical constraint.
A manufacturing IoT platform needs granular cost attribution across three engineering teams sharing a single VPC. This drill explores the strategic differences between user-defined tags, AWS-generated tags, Cost Categories, and Cost Explorer for achieving enterprise-grade FinOps visibility and accountability.
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.
A financial services firm needs to centrally manage global office IP ranges across 50+ AWS accounts. This drill dissects why VPC Prefix Lists with AWS RAM outperform S3-based automation and AWS Config remediation in scalability, cost, and operational simplicity.
When designing multi-region failover for a CloudFront distribution with dynamic content, should you replicate CloudFront, use origin groups, or deploy Global Accelerator? This drill dissects the FinOps and architectural implications.
This drill explores updating an existing S3 bucket from SSE-S3 to customer-managed encryption keys, balancing security requirements with cost and operational complexity.
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.
Explore how to architect serverless applications requiring static egress IPs through NAT Gateway versus Internet Gateway alternatives, with FinOps impact analysis for professional-level decision-making.
A professional-level analysis of migrating on-premises Git webhook integrations to serverless AWS architectures, comparing Lambda Function URLs, API Gateway, App Runner, and ECS Fargate through FinOps and decision trade-off lenses.
