A company is setting up a hybrid network to replicate database transactions from an on-premises data center to an AWS VPC. The replication process requires a consistent network throughput of $2\text{ Gbps}$ and must use a private, dedicated physical connection to minimize latency. Which network architecture solution should the systems architect implement to meet these requirements?

AWS Direct Connect with a dedicated $10\text{ Gbps}$ connection.Answer
B
A single AWS Site-to-Site VPN connection to encrypt and route the replication traffic over the public internet.
C
A VPC peering connection configured with default Network ACLs to automatically track and statefully allow the high-throughput replication return traffic.
D
Amazon Route 53 latency-based routing to dynamically establish the hybrid connection and route traffic to the database endpoint without health checks.

Answer

AWS Direct Connect with a dedicated

10\text{ Gbps}

connection.

AWS Direct Connect establishes a private, physical network connection from an on-premises data center to AWS. A dedicated

10\text{ Gbps}

connection satisfies the requirements of bypassing the public internet and easily sustaining the

2\text{ Gbps}

traffic with low latency.

Step-by-Step Solution

Analyze the requirements for hybrid connectivity.

The requirements dictate a minimum throughput of

2\text{ Gbps}

and a private, dedicated physical network connection.

To filter out internet-based solutions or services with throughput limits below

2\text{ Gbps}

Evaluate the capabilities of the proposed network solutions.

AWS Direct Connect offers dedicated connections of

1\text{ Gbps}

10\text{ Gbps}

over a private link, meeting all requirements. AWS Site-to-Site VPN runs over the internet and is limited to

1.25\text{ Gbps}

per tunnel.

Determining the correct service that matches the physical connection and throughput constraints.

Key Concept

AWS Direct Connect provides dedicated, private physical network connections to AWS that deliver consistent performance, high throughput, and low latency by bypassing the public internet.
