Each Bare Metal Solution environment resides in a secure region extension that is connected to the corresponding Google Cloud region by a Cloud Interconnect connection that is provided and managed by Google Cloud.
Google Cloud monitors round-trip latencies between VM instances in Compute Engine zones and the Bare Metal Solution environment in the same region. For Google Cloud locations in Los Angeles, Ashburn, and London, median round-trip latencies are regularly measured at 0.6 ms to 1 ms.
Cloud Interconnect for Bare Metal Solution
The connection between your Google Cloud environment and your Bare Metal Solution environment uses the Partner Interconnect framework.
For more information about the Partner Interconnect framework, see the Partner Interconnect documentation, but keep in mind the following differences applicable in the context of Bare Metal Solution:
- Because Google Cloud manages the network connection, you provide pairing keys for the VLAN attachments to Google Cloud instead of a third-party service provider.
- This connection to the Bare Metal Solution environment is not subject to the pricing model that the Partner Interconnect product uses. For more information about the pricing model, talk to your Google Cloud Sales representative.
Defining your own IP address spaces
Bare Metal Solution enables you to bring your own IP subnets for use in the bare-metal environment. This enables you to fit your Bare Metal Solution into any existing IP address schema that your enterprise might have.
When you place an order for Bare Metal Solution, you provide two internal IP address ranges: an internal IP range for communication between your Google Cloud and Bare Metal Solution environments and an internal IP range to use to configure back-end routing within the Bare Metal Solution environment.
You can also select the specific IP addresses to use with each machine.
Make sure that no existing IP addresses in your VPC network or your extended on-premises network conflict with the IP ranges that you use for Bare Metal Solution environment.
Multi-region networking considerations
For any outside communication, including communication with services or your on-premises environments, the communication from your Bare Metal Solution environment must pass through the VPC network that you are using to connect to your Bare Metal Solution environment.
Consider using a single VPC network with global_dynamic routing enabled if your Bare Metal Solution environment will require access to other Google Cloud regions to connect to any of the following resources:
- Other Bare Metal Solution environments
- VMs in other regions
- Other Google Cloud services
- Your on-premises sites in other geographical locations
Using a VPC network with global dynamic routing enabled and custom route advertisements, you can set up a routed environment to connect your Bare Metal Solution instances directly to your Google Cloud and extended on-premises environments in other regions, without any additional configuration in Google Cloud.
Our recommendation is to advertise a default route on the BGP sessions to Bare Metal Solution. This enables you to:
- Avoid having to make change to routes to the Bare Metal Solution environment even if things change in your VPC subnets or your on-premises environments.
- Keep the routing table to Bare Metal Solution small and allow it to contain only one prefix.
Network services and your Bare Metal Solution environment
As described earlier, Google Cloud recommends that you advertise a single default route to your Bare Metal Solution environment to keep the routing table simple. However, if your circumstances don't allow that, the routes that you need to expose to your Bare Metal Solution environment are determined by networks and services in your Google Cloud or on-premises environments that need access to the devices or applications in your Bare Metal Solution environment and vice-versa.
Some services that might require routes include NTP servers, DNS servers, LDAP servers, logging services, monitoring services, and so forth, as well as any other workloads and applications that need to communicate with the Bare Metal Solution environment.
Bare Metal Solution does not come with internet access. If you need to, you can setup routing to access the internet through any existing internet gateways that you have, either on Google Cloud or on premises.
Keeping routing simple
Outside of the other machines in the same Bare Metal Solution region, your machines likely need to communicate with one or more of the following:
- Your endpoints in your Google Cloud environment
- Your extended on-premises environment through your Google Cloud environment
- Your machines in Bare Metal Solution environments in other regions through your Google Cloud environment
- The internet through your Google Cloud environment
Because all of your communication from the Bare Metal Solution environment is routed through your Google Cloud environment, to keep routing simple, consider advertising either a default route or all RFC 1918 private addresses, based on your IP schemes toward your Bare Metal Solution. You can do this by using custom route advertisements at the BGP-session level to your Bare Metal Solution environment.
Firewalls and the Bare Metal Solution environment
When planning your firewall implementation for the Bare Metal Solution environment, there are a couple things to consider.
If you need to control traffic between the servers or applications within the Bare Metal Solution environment (east-west traffic), ask your Google Cloud sales representative for the available options.
In your VPC network on Google Cloud, you need to create firewall rules that allow incoming connections from the Bare Metal Solution environment.
Required networking information for your Bare Metal Solution order
When you submit a Bare Metal Solution order, include the following networking information:
- The Google Cloud project ID that you are using with your Bare Metal Solution environment.
- The IP ranges that you intend to use in your Bare Metal Solution environment. For example, an internal IP range for communication with you Google Cloud environment and an internal IP range for use only within the Bare Metal Solution environment.
- The number of VLANs you need in your Bare Metal Solution environment.
- The bandwidth, in 1 Gb increments, that you need between your Google Cloud environment and your Bare Metal Solution environment.
