SAA-C03 - Design High-Performing Architectures - Section 3.8
Determine high-performing and scalable network architectures using VPC design, AWS Direct Connect and AWS Transit Gateway.
Compare VPC peering, AWS Transit Gateway, and AWS Direct Connect as network connectivity options, and explain when each is appropriate based on scale, latency, bandwidth, and management overhead. Recognise that Transit Gateway acts as a hub simplifying many-to-many VPC and on-premises connections, while Direct Connect provides dedicated private bandwidth and consistent latency over a connection that bypasses the public internet.
