Q. What is AWS Direct Connect?
AWS Direct Connect is a network service that provides an alternative to using the Internet to utilize AWS cloud services.

Q. What can I do with AWS Direct Connect?
Using AWS Direct Connect, data that would have previously been transported over the Internet can now be delivered through a private network connection between AWS and your datacenter or corporate network.

Q. What are the benefits of using AWS Direct Connect and private network connections?
In many circumstances, private network connections can reduce costs, increase bandwidth, and provide a more consistent network experience than Internet-based connections.

Q. Which AWS services can be used with AWS Direct Connect?
All AWS services, including Amazon Elastic Compute Cloud (EC2), Amazon Virtual Private Cloud (VPC), Amazon Simple Storage Service (S3), and Amazon DynamoDB can be used with AWS Direct Connect.

Q. Can I use the same private network connection with Amazon Virtual Private Cloud (VPC) and other AWS services simultaneously?
Yes. Each AWS Direct Connect connection can be configured with one or more virtual interfaces. Virtual interfaces may be configured to access AWS services such as Amazon EC2 and Amazon S3 using public IP space, or resources in a VPC using private IP space.

Q. If I’m using Amazon CloudFront and my origin is in my own data center, can I use AWS Direct Connect to transfer the objects stored in my own data center?
Yes. Amazon CloudFront supports custom origins including origins you run outside of AWS. With AWS Direct Connect, you will pay AWS Direct Connect data transfer rates for origin transfer.

Q. Where is AWS Direct Connect available?
You can find the complete list of Direct Connect locations on the Product Details page.

Q. Can I use AWS Direct Connect if my network is not present at an AWS Direct Connect location?
Yes. APN Partners supporting AWS Direct Connect can help you extend your preexisting data center or office network to an AWS Direct Connect location. Please see APN Partners for more information.

Q. How can I get started with AWS Direct Connect?
Use the AWS Direct Connect tab on the AWS Management Console to create a new connection. Then you will change the region to the region you wish to use. When requesting a connection, you will be asked to select the AWS Direct Connect location you wish to use, the number of ports, and the port speed. You will also have the opportunity to request to have an APN Partner contact you if you need assistance extending your office or data center network to the AWS Direct Connect location.

Q. Can I order a port for AWS GovCloud (US) in the AWS Management Console?
If you wish to order a port to connect to AWS GovCloud (US) you will need to use the AWS GovCloud (US) management console. Details about getting started in the AWS GovCloud (US) region can be found here.


Q. Are there any setup charges or a minimum service term commitment required to use AWS Direct Connect?
There are no setup charges, and you may cancel at any time. Services provided by APN Partners may have other terms or restrictions that apply.

Q. How will I be charged and billed for my use of AWS Direct Connect?
AWS Direct Connect has two separate charges: port-hours and Data Transfer. Pricing is per port-hour consumed for each port type. Partial port-hours consumed are billed as full hours.

Data Transfer via AWS Direct Connect will be billed in the same month in which the usage occurred. If you have a hosted virtual interface, you will only be charged for the data transferred out of that virtual interface at the applicable Data Transfer rates. The account that owns the port will be charged the port-hour charges. Read more about hosted virtual interfaces here.

For AWS Direct Connect pricing information, please see AWS Direct Connect pricing. If using an APN partner to facilitate a Direct Connect connection, contact the partner regarding any fees they may charge.

Q. Will regional data transfer be billed at the AWS Direct Connect rate?
No, data transfer between Availability Zones in a region will be billed at the regular regional data transfer rate in the same month in which the usage occurred.

Q. What defines billable port-hours?
Port-hours are billed once the connection between the AWS router and your router is established, or 90 days after you ordered the port, whichever comes first. Port charges will continue to be billed anytime the AWS Direct Connect port is provisioned for your use. If you no longer wish to be charged for your port, please follow the cancellation process detailed in How do I cancel the AWS Direct Connect service?.

Q. How does AWS Direct Connect work with consolidated billing?
AWS Direct Connect data transfer usage will be aggregated to your master account.

Q. How do I cancel the AWS Direct Connect service?
You can cancel AWS Direct Connect service by deleting your ports from the AWS management console. You should also cancel any service(s) offered by a third party. For example, contact the colocation provider to disconnect any cross-connects to AWS Direct Connect, and/or a network service provider who may be providing network connectivity from your remote locations to the AWS Direct Connect location.

Q: Do your prices include taxes?
Except as otherwise noted, our prices are exclusive of applicable taxes and duties, including VAT and applicable sales tax. For customers with a Japanese billing address, use of the Asia Pacific (Tokyo) region is subject to Japanese Consumption Tax. Learn more.

Q. What connection speeds are supported by AWS Direct Connect?
1Gbps and 10Gbps ports are available.Speeds of 50Mbps, 100Mbps, 200Mbps, 300Mbps, 400Mbps, and 500Mbps can be ordered from any APN partners supporting AWS Direct Connect. Read more about APN Partners supporting AWS Direct Connect.

Q. Are there limits on the amount of data that I can transfer using AWS Direct Connect?
No. You may transfer any amount of data up to the limit of your selected port speed.

Q. What are the technical requirements for the connection?
AWS Direct Connect supports 1000BASE-LX or 10GBASE-LR connections over singlemode fiber using Ethernet transport. Your device must support 802.1Q VLANs. See the AWS Direct Connect User Guide for more detailed requirements information.

Q. What AWS region(s) can I connect to via this connection?
Each AWS Direct Connect location enables connectivity to the geographically nearest AWS region. You can access all AWS services available in that region.

Direct Connect locations in the US can also access the public endpoints of the other AWS regions using a public virtual interface.

Q. What Availability Zone(s) can I connect to via this connection?
Each AWS Direct Connect location enables connectivity to all Availability Zones within the geographically nearest AWS region.

Q. Are connections to AWS Direct Connect redundant?
Each connection consists of a single dedicated connection between ports on your router and an Amazon router. We recommend establishing a second connection if redundancy is required. When you request multiple ports at the same AWS Direct Connect location, they will be provisioned on redundant Amazon routers.

Q. Will I lose connectivity if my AWS Direct Connect link fails?
If you have established a second AWS Direct Connect connection, traffic will failover to the second link automatically. We recommend enabling Bidirectional Forwarding Detection (BFD) when configuring your connections to ensure fast detection and failover. If you have configured a back-up IPsec VPN connection instead, all VPC traffic will failover to the VPN connection automatically. Traffic to/from public resources such as Amazon S3 will be routed over the Internet. If you do not have a backup AWS Direct Connect link or a IPsec VPN link, then Amazon VPC traffic will be dropped in the event of a failure. Traffic to/from public resources will be routed over the Internet.

Q. Can I extend one of my VLANs to the AWS Cloud using AWS Direct Connect?
No, VLANs are utilized in AWS Direct Connect only to separate traffic between virtual interfaces.

Q. Does AWS Direct Connect offer a Service Level Agreement (SLA)?
Not at this time.

Q: What are the technical requirements for virtual interfaces to public AWS services such as Amazon EC2 and Amazon S3?
This connection requires the use of the Border Gateway Protocol (BGP) with an Autonomous System Number (ASN) and IP Prefixes. You will need the following information to complete the connection:

  • A public or private ASN. If you are using a public ASN, you must own it. If you are using a private ASN, it must be in the 64512 to 65535 range.
  • A new unused VLAN tag that you select
  • Public IPs (/30) allocated by you for the BGP session

Amazon will advertise public IP prefixes for the region via BGP. Direct Connect customers in the US will receive the public IP prefixes for all US regions. You must advertise public IP prefixes (/30 or smaller) that you own via BGP. For more details, consult the AWS Direct Connect User Guide.

Q: What is an Autonomous System Number (ASN) and do I need one to use AWS Direct Connect?
Autonomous System numbers are used to identify networks that present a clearly defined external routing policy to the Internet. AWS Direct Connect requires an ASN to create a public or private virtual interface. You may use a public ASN which you own, or you can pick any private ASN number between 64512 to 65535 range.

Q. What IP address will be assigned to each end of a virtual interface?
If you are configuring a virtual interface to the public AWS cloud, the IP addresses for both ends of the connection must be allocated from public IP space that you own. If the virtual interface is to a VPC and you choose to have AWS auto-generate the peer IP CIDR, the IP address space for both ends of the connection will be allocated by AWS in the 169.254.0.0/16 range.

Q: Can I connect to the Internet via this connection?
No.

Q: If I have more than one virtual interface attached, can I exchange traffic between the two ports?
Not for public Direct Connect virtual interfaces; but you can exchange traffic between the two ports in the same region if they are connecting to the same VGW.

Q: When creating a virtual interface to work with AWS services using public IP space, what IP prefixes will I receive via BGP?
You will receive all Amazon IP prefixes for the region that you are connecting to. This includes prefixes necessary to reach AWS services, and may include prefixes for other Amazon affiliates, including those of www.amazon.com. For the current list of prefixes advertised by AWS, please download the JSON of AWS IP Address Ranges. Direct Connect customers in the US will receive the public IP prefixes for all US regions. Standard AWS Direct Connect data transfer rates apply for all traffic routed through your AWS Direct Connect connection. Please see the AWS Direct Connect community forum for the additional details in the routing policy of the public virtual interface.

Q. What IP prefixes should I advertise over BGP for virtual interfaces to public AWS services?
You should advertise appropriate public IP prefixes that you own over BGP. Traffic from AWS services destined for these prefixes will be routed over your AWS Direct Connect connection.

Q. Can I locate my hardware next to the equipment that powers AWS Direct Connect?
You can procure rack space within the facility housing the AWS Direct Connect location and deploy your equipment nearby. However, AWS customer equipment cannot be placed within AWS Direct Connect racks or cage areas for security reasons. For more information, contact the APN Partner for the particular facility. Once deployed, you can connect this equipment to AWS Direct Connect using a cross-connect.

Q. How do I enable BFD on my Direct Connect connection?

Asynchronous BFD is automatically enabled for each Direct Connect virtual interface, but will not take effect until it's configured on your router. AWS has set the BFD liveness detection minimum interval to 300, and the BFD liveness detection multiplier to 3.

Q. How do I set up Direct Connect for the AWS GovCloud (US) Region?
See the AWS GovCloud (US) User Guide for detailed instructions on how to set up a Direct Connect connection for the AWS GovCloud (US) region.

Q. What are the technical requirements for virtual interfaces to VPCs?
This connection requires the use of Border Gateway Protocol (BGP). You will need the following information to complete the connection:

  • A public or private ASN. If you are using a public ASN you must own it. If you are using a private ASN, it must be in the 64512 to 65535 range.
  • A new unused VLAN tag that you select
  • The VPC Virtual Private Gateway (VGW) ID

AWS will allocate private IPs (/30) in the 169.x.x.x range for the BGP session and will advertise the VPC CIDR block over BGP. You can advertise the default route via BGP.

Q. How does AWS Direct Connect differ from an IPSec VPN Connection?
A VPC VPN Connection utilizes IPSec to establish encrypted network connectivity between your intranet and Amazon VPC over the Internet. VPN Connections can be configured in minutes and are a good solution if you have an immediate need, have low to modest bandwidth requirements, and can tolerate the inherent variability in Internet-based connectivity. AWS Direct Connect does not involve the Internet; instead, it uses dedicated, private network connections between your intranet and Amazon VPC.

Q. Can I use AWS Direct Connect and a VPN Connection to the same VPC simultaneously?
Yes. However, only in fail-over scenarios. The Direct Connect path will always be preferred, when established, regardless of AS path prepending.

Q. Can I establish a Layer 2 connection between VPC and my network?
No, Layer 2 connections are not supported.

 

Q. Can I run IPv4 and IPv6 on the same virtual interface (VIF)?

AWS Direct Connect supports both single and dual stack configurations on public and private VIFs. You will be able to add an IPv6 peering session to an existing VIF with IPv4 peering session (or vice versa). You can also create 2 separate VIFs – one for IPv4 and another one for IPv6

Q. I need a public IPv6 range, can Amazon assign me a range?

Yes. Addressing for both public and private VIFs is provided by default and with a netmask of /125.

Q. What IP address will Amazon assign my private VIF if I select “assign an IP” in the console?

For a private IPv4 VIF, Amazon will provide you a /31 CIDR. For a private IPv6 VIF, Amazon will provide you a /125 CIDR.

Q. Will I still need to run BGP on my VIFs?

Yes. Both private and public Direct Connect require a native peering from IPv4 or IPv6. Multiprotocol BGP is not supported at this time.

Q. Can I bring my own BGP ASN?
At this time, you will not be able to bring your own BGP ASN. This feature is on the Direct Connect roadmap, and once enabled, you will be able to bring your own BGP ASN for the VIFs.

Q. Are there any changes to VLAN assignment?

No. Layer 2 functionality remains the same for IPv4 and IPv6.

Q. Will I still be able to use BFD for faster BGP failover times?

Yes. BFD is supported for IPv6 BGP peerings.

Q. Are there any changes in prefix limits?

Yes, for IPv6 we will limit the peer IPv6 CIDR advertisements to /64. For IPv4, prefix limits will remain the same.

Q. What routes will AWS announce to me over a public VIF?

All public routes.

Q. Will AWS set communities on routes in BGPv6 so I can filter which routes I install?

Yes. You can filter on communities.

Q. Will you support multicast or anycast over IPv6 VIFs?

We will not support multicast or anycast on Direct Connect.

Q. What routes will I learn from AWS over a public VIF?

AWS Public Direct Connect will advertise IPv6 prefixes for all IPv6 enabled services.

Q. Can I create a hosted virtual interface for someone that is IPv6 enabled?

Yes you can.

Q. Will this impact partner policers on their NNI ports at all?

It will not.

Q. Will cloudhub still work in my VGW? (note also impacts VPN)

It will only work for like for like traffic. You can’t send v4 traffic out a v6 interface, for example. Translation between IPv4 and IPv6 is not supported.

Q. Can I have v4 and v6 BGP sessions running over a single VPN tunnel?
At this time, we will only allow v4 BGP session running single VPN tunnel with IPv4 address. In future, we will allow v6 BGP sessions running over the single VPN tunnel with IPv4 endpoint address.

Q. Is there any difference to the BGP configuration/setup details outlined for DX?
VPN BGP will work the same as DX

Q. Can I terminate my tunnel to an endpoint with an IPv6 address?
At this time, we will only support IPv4 endpoint address for VPN. In future, we will support VPN endpoint with IPv6 address.

Q. Can I terminate my tunnel to an IPv4 address and run IPv6 BGP sessions over the tunnel?
At this time, we will only allow v4 BGP session running single VPN tunnel with IPv4 address. In future, we will allow v6 BGP sessions running over the single VPN tunnel with IPv4 endpoint address.
