AWS Direct Connect vs. VPN: Which is the best option for your business?

Network connectivity plays a crucial role in the infrastructure of any modern enterprise. With the mass adoption of hybrid and multi-cloud architectures, the need for a stable, secure and high-performance connection has never been more important. In this context, many are faced with the decision of whether to choose between AWS Direct Connect and traditional VPNs (Virtual Private Networks). Both solutions have their advantages, but when comparing their capabilities and benefits, it is clear that AWS Direct Connect is positioned as the best option for companies looking for optimized, flexible and scalable connectivity.

If you're an experienced IT professional or solutions architect, you'll know that VPNs have long been the standard solution for connecting remote networks. However, as your business needs grow and expand into multiple cloud environments, the limitations of a traditional VPN can become apparent. This is where AWS Direct Connect presents itself as a more robust and efficient alternative. Let's break down the differences between the two options so you can make an informed decision on which solution is best for your infrastructure.

AWS Direct Connect: High Performance and Secure Connectivity

It is a solution that allows you to establish a private, dedicated, high-capacity connection between your local infrastructure and AWS services. By using a connection that does not rely on the Internet, Direct Connect reduces latency and improves the stability and security of communications, making it an excellent choice for businesses with large data transfer requirements and critical applications that demand high performance.

What is a VPN?

A VPN (Virtual Private Network) creates a private, encrypted network over the Internet, allowing your local infrastructure to securely connect to remote resources in the cloud or other locations. While VPNs are relatively easy to implement and may be cheaper initially, their reliance on the public Internet can lead to performance, security and scalability issues as the volume of data and complexity of the infrastructure grows.

In terms of hybrid and multicloud connectivity, VPNs often require multiple configurations and maintenance to handle the interconnection of different clouds or local resources. In addition, connection latency and availability are dependent on the public infrastructure, which can result in performance variability and management difficulties as business needs expand.

AWS Direct Connect vs. VPN: Which is the best option?

Performance and Stability

When it comes to performance, AWS Direct Connect takes the lead. As a private, dedicated connection, it is unaffected by Internet congestion, which means you experience lower latency, greater stability and more predictable performance. VPNs, on the other hand, are subject to the variability of the public network, which can lead to inconsistent latency and slower speed, especially in high-traffic scenarios.

• AWS Direct Connect: High capacity, low latency and stability, ideal for large data volumes.
• VPN: Variable performance, with latency and congestion issues due to the public Internet network.

Security

Security is a crucial issue for companies that handle sensitive data or operate in highly regulated industries. AWS Direct Connect offers a significant advantage in terms of security by avoiding the transmission of data over the public Internet. With a dedicated connection, the risk of interception or man-in-the-middle attacks is greatly reduced.

On the other hand, VPNs encrypt the traffic flowing over the Internet, but still rely on the public network, which can expose the communication to more vulnerabilities, especially if additional protection measures are not properly implemented.

• AWS Direct Connect: Private, more secure and controlled connection with end-to-end encryption.
• VPN: Encryption over public Internet, but with higher risks due to external infrastructure.

Scalability and Flexibility

If you are running a hybrid or multi-cloud infrastructure, scalability is a key factor. AWS Direct Connect is much more flexible in adapting to the growth of your business. It allows you to increase connection capacity as needed, add dedicated links, and connect multiple cloud environments seamlessly.

• AWS Direct Connect: Nondisruptive scalability, ideal for growing businesses or those with high data volume needs.
• VPN: Limited in capacity, difficult to scale as infrastructure becomes more complex.

Costs

VPNs may seem more economical at first, especially for smaller companies or those with limited connectivity needs. However, as the volume of data traffic increases, the costs associated with transferring data and managing multiple connections can grow rapidly. VPNs also require more maintenance as the infrastructure expands.

AWS Direct Connect, although it has a higher upfront cost due to the dedicated infrastructure, is more efficient in terms of long-term operating costs. With Direct Connect, data transfer costs are more predictable and favorable for businesses with high bandwidth requirements.

• AWS Direct Connect: Lower and more predictable data transfer costs as you scale.
• VPN: Variable costs that can increase with intensive use of the public network.

Business Continuity

Availability is crucial to maintain business continuity. AWS Direct Connect allows you to set up redundant links and establish failover options, ensuring that your network is available even if one of the connections fails. VPNs can offer redundancy, but they rely on public infrastructure, which makes them more susceptible to connectivity issues and external failures.

• AWS Direct Connect: Configurable high availability and redundancy.
• VPN: Less reliability and dependence on the Internet.

Which option is best for your business?

The decision between AWS Direct Connect and VPN will depend on the specific needs of your infrastructure. If your business is growing or already runs a hybrid or multicloud infrastructure, AWS Direct Connect is the more robust and scalable option. It offers better performance, greater security and more predictable operating costs, making it the ideal solution for businesses that need high-end connectivity.

If your company has a smaller infrastructure or connectivity needs are limited, a VPN may be enough to get you started. However, if you're looking for a long-term solution that can scale as your business grows, AWS Direct Connect is the best investment.
