Explore how to minimize operational overhead when deploying applications to constantly changing EC2 fleets using CodeDeploy, Auto Scaling Groups, and AMI baking strategies - a critical SAP-C02 competency.
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.
When network appliances fail in auto-scaling groups, static routes become stale. This SAP-C02 scenario explores the orchestration pattern combining custom metrics, event-driven automation, and Lambda-based route reconciliation—a real-world decision between operational complexity and infrastructure reliability.
This drill dissects a multi-region high availability and DR scenario, comparing active-active vs. active-passive architectures, VPC peering misconceptions, and Route 53 routing policy selections—with quantified FinOps impact for professional-level decision-making.
Discover why choosing the right storage architecture for auto-scaling workloads isn’t just about capacity—it’s about understanding shared access patterns, operational overhead, and the hidden costs of complexity.
When migrating a multi-tier application to AWS, choosing between synchronous scaling and asynchronous decoupling determines both operational efficiency and long-term TCO. This drill explores why queue-based architectures win for resilience.
Discover why choosing the right load balancer type is critical for detecting application-layer failures and improving availability without custom scripting.
A high-level analysis of DynamoDB billing models (Provisioned vs. On-Demand) and how Reserved Capacity combined with Auto Scaling delivers optimal TCO for write-heavy workloads with predictable weekly peaks.
A simulated SAA-C03 scenario exploring how to architect high availability for a mission-critical web application using Aurora PostgreSQL and Auto Scaling groups, focusing on the balance between availability guarantees and operational simplicity.
A Professional-level analysis of migrating a traffic-surge-prone .NET application to AWS, comparing Elastic Beanstalk vs CloudFormation, Aurora vs RDS MySQL, and multi-AZ vs multi-Region strategies for 200K daily users.
