AWS Direct Connect - Amazon Virtual Private Cloud Connectivity Options

AWS Direct Connect

AWS Direct Connect makes it easy to establish a dedicated connection from an on-premises network to one or more VPCs in the same region. Using private VIF on AWS Direct Connect, you can establish private connectivity between AWS and your data center, office, or colocation environment, as shown in the following figure.

Multiple dynamically routed AWS Direct Connect connections are necessary to support high availability, as shown in the following figure.

AWS Direct Connect can reduce network costs, increase bandwidth throughput, and provide a more consistent network experience than internet-based connections. It uses industry-standard 802.1q VLANs to connect to Amazon VPC using private IP addresses. You can choose from an ecosystem of WAN service providers for integrating your AWS Direct Connect endpoint in an AWS Direct Connect location with your remote networks. AWS Direct Connect lets you establish 1 Gbps or 10 Gbps dedicated network connections (or multiple connections) between AWS networks and one of the AWS Direct Connect locations. You can also work with your provider to create sub-1G connection or use link aggregation group (LAG) to aggregate multiple 1 gigabit or 10 gigabit connections at a single AWS Direct Connect endpoint, allowing you to treat them as a single, managed connection.

A Direct Connect gateway is a globally available resource to enable connections to multiple Amazon VPCs across different regions or AWS accounts. This feature also allows you to connect to any participating VPCs from one private VIF, reducing AWS Direct Connect management, as shown in the following figure.
