Question

A company needs a secure connection between its on-premises environment and AWS. This connection does not need high bandwidth and will handle a small amount of traffic. The connection should be set up quickly. What is the MOST cost-effective method to establish this type of connection?

Accepted Answer

Let's map each requirement to the answer:

1. **Secure connection between on-premises and AWS**: Site-to-Site VPN creates an IPsec encrypted tunnel between your on-premises network and your AWS VPC. This satisfies the security requirement.

2. **Low bandwidth / small amount of traffic**: Site-to-Site VPN supports up to 1.25 Gbps per tunnel, which is more than sufficient for small traffic volumes. You don't need the dedicated bandwidth of Direct Connect.

3. **Set up quickly**: This is a critical differentiator. Site-to-Site VPN can be provisioned in **minutes** — you create a Virtual Private Gateway (or Transit Gateway), a Customer Gateway, and configure the VPN connection. Your on-premises router just needs to support IPsec.

4. **Most cost-effective**: You pay only for the VPN connection
