Some workloads running in Google Cloud require low latency between their VM instances in a specified region and the Dedicated Interconnect colocation facility you choose. If this is true for your workloads, you can select a low-latency (< 5 milliseconds) colocation facility location from the Locations table in this document.
The pricing for low-latency locations is the same as for all other locations.
If your workloads don't require low-latency connectivity, you can use any of our colocation facilities locations.
Requirements and recommendations
For Dedicated Interconnect your network must physically meet Google's network in a supported colocation facility, also known as an interconnect location), where a vendor, the colocation facility provider, provisions a circuit between your network and a Google Edge Point of Presence. For more information, see the Cloud Interconnect Overview.
The Region served as listed in the table below indicates the regions in which you can
create VLAN attachments,
which affects latency and egress costs.
For example, if you have VM instances in region us-east4 (Virginia), you might
create a dedicated connection in Ashburn and then create an interconnect
attachment (VLAN) in us-east4. That way, your traffic doesn't have to travel
far to move between your VM instances and the dedicated connection, resulting in
lower latency than, for example, creating a dedicated connection and an
interconnect attachment in Europe.
Also, it's more cost effective to create interconnect attachments in the same regions as your VM instances because you don't have to pay inter-region egress costs when VM instances send traffic to your on-premises network.
Other Google Cloud location options
- Network edge locations allow you to peer with Google Cloud and connect to Google Cloud services. Peering does not require Cloud Interconnect.
- Cloud CDN locations use Google's globally distributed edge points of presence to cache HTTP(S) load balanced content close to your users. Caching content at the edges of Google's network provides faster delivery of content to your users while reducing serving costs.
Locations table
The following table lists low-latency locations where you can create dedicated
connections. The locations are organized by the Google Cloud regions served, metropolitan
area, and
then by metropolitan
availability zone.
The name of each location indicates its metropolitan availability zone, such as
the zone1 in iad-zone1-1.
You can also use the console or gcloud command-line tool to list locations.
