A hybrid enterprise needs to connect hundreds of VPCs across AWS accounts to on-premises infrastructure while maintaining granular routing control. This drill examines Transit Gateway architecture, cross-account sharing via AWS RAM, and the FinOps implications of centralized vs. distributed network topologies.
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.
Enable bucket default encryption for future writes, then use S3 Inventory + S3 Batch Operations to re-encrypt millions of existing objects in-place with minimal effort.
When an app runs behind ALBs in multiple AWS Regions and you want the best user performance, Route 53 latency-based routing (A/alias) is the default decision.
How do you balance infrastructure isolation, automation efficiency, and FinOps discipline when provisioning ephemeral test environments that require on-premises connectivity? This SAP-C02 drill explores Transit Gateway attachment strategies and Infrastructure-as-Code patterns.
When workload grows on RDS for PostgreSQL but you can’t add new infrastructure, the most cost-effective path is typically vertical scaling plus committing with Reserved Instances.
Exploring how to extend an existing two-AZ VPC architecture to incorporate a new AZ without expanding IPv4 CIDR range or downtime, with a focus on subnet resizing trade-offs.
