AWS Certified Advanced Networking Specialty Practice Exam

Why is AWS Direct Connect preferred for hybrid cloud architectures?

1. It allows access to all services in AWS without restrictions

2. It offers guaranteed network performance with low latency

3. It removes upstream bottlenecks in public internet

4. It offers free data transfer between locations

The correct answer is: It offers guaranteed network performance with low latency

AWS Direct Connect is preferred for hybrid cloud architectures primarily because it offers guaranteed network performance with low latency. This service provides a dedicated network connection from your premises directly to AWS, bypassing the public internet. As a result, you can achieve more consistent bandwidth and lower latency compared to typical internet connections, which can be affected by various factors such as congestion and routing issues. In hybrid cloud environments, where workloads might span both on-premises infrastructure and AWS resources, having a reliable network connection is crucial. By using AWS Direct Connect, organizations can ensure that their applications perform optimally, which is especially important for latency-sensitive applications or those requiring large data transfers between on-premises environments and AWS. This dedicated connection not only enhances performance but also improves security, as data travels through a private connection rather than over the public internet, reducing the exposure to potential vulnerabilities. Such capabilities make Direct Connect appealing for businesses that need to maintain strong performance and reliability while integrating on-premises and cloud resources.
