Which AWS service or feature requires an internet service provider (ISP) and a colocation facility to be implemented?

AWS VPN (Virtual Private Network) establishes an encrypted tunnel over the public internet and does not require a colocation facility or specific ISP engagement beyond standard internet access.

Amazon Connect is a cloud-based contact center service that only requires internet access for agents and customers, not physical colocation.

AWS Direct Connect requires physical infrastructure, specifically a connection to an AWS Direct Connect location, which is often found within a colocation facility where customers can cross-connect their network equipment. This setup also typically involves working with an ISP or a Direct Connect partner to extend the connection from the customer's data center to the colocation facility.

An Internet Gateway is a logical component in a VPC that allows communication between instances in the VPC and the internet and does not require physical colocation or specific ISP engagement beyond AWS's own infrastructure.
