A company needs to minimize the cost of its 1 Gbps AWS Direct Connect connection. The company's average connection utilization is less than 10%. A solutions architect must recommend a solution that will reduce the cost without compromising security. Which solution will meet these requirements?

A
Set up a new 1 Gbps Direct Connect connection. Share the connection with another AWS account.
B
Set up a new 200 Mbps Direct Connect connection in the AWS Management Console.
C
Contact an AWS Direct Connect Partner to order a 1 Gbps connection. Share the connection with another AWS account.
D
Contact an AWS Direct Connect Partner to order a 200 Mbps hosted connection for an existing AWS account.
Explanation:
Explanation
Correct Answer: D
Why Option D is correct:
-
Cost Optimization: The company's current 1 Gbps Direct Connect connection has less than 10% utilization (less than 100 Mbps). A 200 Mbps hosted connection would be more appropriately sized for their actual needs, significantly reducing costs while still providing sufficient capacity.
-
Hosted Connection via Partner: AWS Direct Connect Partners offer hosted connections that can be provisioned at various speeds (50 Mbps, 100 Mbps, 200 Mbps, 300 Mbps, 400 Mbps, 500 Mbps, 1 Gbps, 2 Gbps, 5 Gbps, and 10 Gbps). This allows for right-sizing the connection based on actual usage patterns.
-
Security: Using a hosted connection for an existing AWS account maintains the same security posture without sharing the connection with other accounts.
Why other options are incorrect:
-
Option A: Setting up a new 1 Gbps connection and sharing it with another account doesn't reduce costs - it maintains the same expensive 1 Gbps capacity while adding complexity of sharing.
-
Option B: Direct Connect connections cannot be ordered directly through the AWS Management Console at 200 Mbps. Standard Direct Connect connections are available at 1 Gbps or 10 Gbps speeds only. Hosted connections (available through partners) offer more granular speed options.
-
Option C: Ordering a 1 Gbps connection through a partner and sharing it maintains the same high cost and doesn't address the underutilization issue.
Key AWS Direct Connect Concepts:
- Standard Direct Connect: Available at 1 Gbps or 10 Gbps speeds, ordered directly from AWS
- Hosted Connections: Available through AWS Direct Connect Partners at various speeds (50 Mbps to 10 Gbps)
- Connection Sharing: Allows multiple AWS accounts to use the same physical connection, but doesn't reduce the base cost of the connection itself
- Right-sizing: Critical for cost optimization - match connection capacity to actual usage patterns
Best Practice: When utilization is consistently low (less than 10% in this case), consider downsizing to a hosted connection through a partner to optimize costs while maintaining security and performance requirements.
