In most cases you will need to work with an AWS Direct Connect Partner to get your connection set up.
A Hosted Virtual Interface has access to all of the available capacity on the network link between the AWS Direct Connect Partner and an AWS Direct Connect location.
The network link between the AWS Direct Connect Partner and the AWS Direct Connect location is shared by multiple customers and could possibly be oversubscribed.
These capacities will be available through a select set of AWS Direct Connect Partners who have been specifically approved by AWS.
We are also working with AWS Direct Connect Partners to implement additional monitoring of the network link between the AWS Direct Connect Partners and AWS.
