This pillar teaches the decision logic behind AWS hybrid connectivity options. Learn when to choose Direct Connect versus VPN, understand bandwidth and latency requirements, and master the multi-site connectivity patterns that appear throughout SAP-C02.
Learn why NAT Gateway placement in public subnets across all AZs is the AWS-recommended pattern for private subnet internet access, and understand the hidden cost implications of high availability decisions.
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.
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 manufacturing company needs high-availability hybrid connectivity to AWS with stable latency, minimal cost, and tolerance for slower backup. Learn why Direct Connect + VPN backup is the optimal solution over dual Direct Connect or dual VPN approaches.
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.
Migrating a mission-critical analytics platform with mixed workload profiles (SLA-bound scheduled jobs + best-effort user tasks) requires a strategic balance between On-Demand capacity reservations and Spot instance cost savings across multi-AZ deployment.
This SAP-C02 scenario explores how to architect a multi-AZ, internet-facing TCP service with fixed IP addresses for client whitelisting. The challenge lies in balancing NLB capabilities, Elastic IP allocation strategies, and DNS configuration while maintaining cost efficiency and operational simplicity.
When a product catalog lives on volatile instance store, choosing the right persistent storage requires balancing durability, availability, access patterns, and cost—this drill dissects the SAA-C03 logic.
When an e-commerce database can’t keep up with unpredictable read traffic, the solution isn’t just about adding capacity—it’s about choosing the right scaling model that balances performance, availability, and operational simplicity.
