Connecting to AWS

Connecting your network to Amazon Web Services (AWS) is a common scenario for organizations looking to extend their infrastructure to the cloud. AWS offers several ways to establish a reliable, secure, and high-performance connection. In this article, we discuss the main options and practical considerations, including the possibility of connecting via a partner using Cloud Connect.

1. Direct Connection via AWS Direct Connect

AWS Direct Connect is a service that provides a dedicated network connection between your data center or office and the AWS cloud. The main advantage of Direct Connect is a stable, low-latency connection, often with higher bandwidth and predictable performance compared to standard internet connections.

Key points:

• Direct Connect requires physical connections at an AWS location (AWS Direct Connect Location).
• It provides private VLANs (Virtual LANs) to create multiple virtual interfaces.
• Bandwidth options range from 50 Mbps to 100 Gbps, depending on location and provider.
• Redundancy can be achieved by using multiple Direct Connect lines, allowing traffic to automatically fail over in case one line goes down.

2. VPN Connections over the Internet

Another way to reach AWS is through a Virtual Private Network (VPN). AWS supports site-to-site VPN, which securely connects your existing network to AWS over the internet.

Advantages:

• Quick to deploy: only requires internet access and a suitable VPN router.
• Secured with encryption (IPSec).
• Suitable for hybrid cloud environments or as a temporary solution.

Limitations:

• Latency and throughput depend on the quality of the internet connection.
• Less suitable for very high-volume or performance-critical applications.

3. AWS Transit Gateway for Complex Networks

If you manage multiple AWS accounts or regions, an AWS Transit Gateway can help centralize your networks. It enables you to connect multiple Virtual Private Clouds (VPCs) and on-premises networks through a single central gateway.

Advantages:

• Simplifies network architecture when managing multiple VPCs.
• Scalable and manageable from a single point.
• Allows efficient routing, security, and network segmentation.

4. Connecting via Cloud Connect through a Partner

A growing option is using Cloud Connect through a certified partner. In this setup, the partner handles the physical connection and management of the AWS connection.

Advantages:

• No need to invest in expensive network equipment or physical lines.
• Technical expertise to establish and manage the connection is not required.
• Often includes monitoring and management, ensuring continuity.
• Ideal for organizations that want a fast, reliable connection without dedicating internal resources.

5. Key Considerations

When designing a connection to AWS, it’s important to consider:

1. Security: Use encrypted connections and restrict network access to only necessary resources.
2. Redundancy and failover: Plan for potential outages, for example by deploying multiple lines or connections.
3. Bandwidth and performance: Assess your data traffic to determine which option is best.
4. Cost: Direct Connect has fixed costs plus per-GB fees; VPN over the internet is flexible but may incur variable internet costs; Cloud Connect via a partner can be cost-effective since investments and management are outsourced.

6. Conclusion

Connecting your network to AWS can be done in multiple ways, depending on your needs for speed, reliability, scalability, and available resources. Whether you choose direct connections via Direct Connect, an internet VPN, a Transit Gateway for complex networks, or Cloud Connect through a partner, a well-planned design ensures security, redundancy, and performance.
