AWS Certified Solutions Architect – Associate (SAA-C03)Design High-Performing ArchitecturesMedium
A data analytics company processes large datasets daily, requiring high-bandwidth, low-latency network connectivity between their on-premises data center and AWS VPC. The existing internet VPN connection is insufficient for the volume of data transferred and introduces unacceptable latency. They need a dedicated, private connection that ensures consistent network performance and enhanced security.
- AImplement a public internet gateway on the VPC to maximize throughput.
- BEstablish an AWS Direct Connect connection between the data center and AWS.
- CUpgrade the internet VPN connection to a higher bandwidth.
- DUse AWS Site-to-Site VPN with accelerated VPN.
Show answer & explanationAnswer & explanation
Correct answer: B. Establish an AWS Direct Connect connection between the data center and AWS.
AWS Direct Connect provides a dedicated, private network connection from your on-premises data center to AWS. This bypasses the public internet, offering consistent network performance, reduced latency, and increased bandwidth, which is ideal for transferring large datasets and building hybrid cloud environments with enhanced security.
Why the other options are wrong
- A. A public internet gateway is for outbound internet access from a VPC; it does not provide a private, high-bandwidth connection from on-premises to AWS.
- C. Upgrading VPN bandwidth might help with volume but won't solve the latency issue inherent to public internet routes or provide dedicated, consistent performance.
- D. Accelerated VPN uses AWS Global Accelerator to route VPN traffic over the AWS global network, which improves performance over the public internet, but it's still a VPN over the internet, not a dedicated private line like Direct Connect.
AWS Direct Connect
AWS Direct Connect is a cloud service solution that links your internal network to an AWS Direct Connect location over a standard Ethernet fiber-optic cable.
- Dedicated network connection from on-premises to AWS.
- Bypasses the public internet.
- Reduces network costs, increases bandwidth throughput, and provides a more consistent network experience.
- Supports various connection speeds from 50 Mbps to 100 Gbps.
Memory trick: Direct Connect: Dedicated, Data-Driven, Dependable.
