It adopts the common “hub and spoke” reference design, which is well suited for multiple scenarios, and it offers several advantages versus other designs:
|
||||
|
||||
- the "trusted hub" VPC centralizes the external connectivity towards trusted network resources (e.g. on-prem, other cloud environments and the spokes), and it is ready to host cross-environment services like CI/CD, code repositories, and monitoring probes
|
||||
- the "landing hub" VPC centralizes the external connectivity towards landing network resources (e.g. on-prem, other cloud environments and the spokes), and it is ready to host cross-environment services like CI/CD, code repositories, and monitoring probes
|
||||
- the "spoke" VPCs allow partitioning workloads (e.g. by environment like in this setup), while still retaining controlled access to central connectivity and services
|
||||
- Shared VPCs -both in hub and spokes- split the management of the network resources into specific (host) projects, while still allowing them to be consumed from the workload (service) projects

- the design facilitates DNS centralization

The "landing zone" is divided into two VPC networks:
|
||||
|
||||
- the trusted VPC: the connectivity hub towards other trusted networks
|
||||
- the untrusted VPC: the connectivity hub towards any other untrusted network
|
||||
- the landing VPC: the connectivity hub towards other landing networks
|
||||
- the dmz VPC: the connectivity hub towards any other dmz network
|

The VPCs are connected with two sets of sample NVA machines, grouped in regional (multi-zone) [Managed Instance Groups (MIGs)](https://cloud.google.com/compute/docs/instance-groups). The appliances are plain Linux machines, performing simple routing/natting, leveraging some standard Linux features, such as *ip route* or *iptables*. The appliances are suited for demo purposes only and they should be replaced with enterprise-grade solutions before moving to production.
|

The traffic destined to the VMs in each MIG is mediated through regional internal load balancers, both in the trusted and in the untrusted networks.

By default, the design assumes the following:

||||
|
||||
- on-premise networks (and related resources) are considered trusted. As such, the VPNs connecting with on-premises are terminated in GCP, in the trusted VPC
|
||||
- the public Internet is considered untrusted. As such [Cloud NAT](https://cloud.google.com/nat/docs/overview) is deployed in the untrusted landing VPC only
|
||||
- cross-environment traffic and traffic from any untrusted network to any trusted network (and vice versa) pass through the NVAs. For demo purposes, the current NVA performs simple routing/natting only
|
||||
- any traffic from a trusted network to an untrusted network (e.g. Internet) is natted by the NVAs. Users can configure further exclusions

- on-premise networks (and related resources) are considered landing. As such, the VPNs connecting with on-premises are terminated in GCP, in the landing VPC

External connectivity to on-prem is implemented leveraging [Cloud HA VPN](https://cloud.google.com/network-connectivity/docs/vpn/concepts/topologies) (two tunnels per region). This is what users normally deploy as a final solution, or to validate routing and to transfer data, while waiting for [interconnects](https://cloud.google.com/network-connectivity/docs/interconnect) to be provisioned.

Connectivity to additional on-prem sites or to other cloud providers should be implemented in a similar fashion, via VPN tunnels or interconnects, in the landing VPC (either trusted or untrusted, depending by the nature of the peers), sharing the same regional routers.

Internal connectivity (e.g. between the trusted landing VPC and the spokes) is realized with VPC network peerings. As mentioned, there are other ways to implement connectivity. These can be easily retrofitted with minimal code changes, although they introduce additional considerations on service interoperability, quotas and management.

|
||||
- Pros: no additional costs, full bandwidth with no configurations, no extra latency
|
||||
- Cons: no transitivity (e.g. to GKE masters, Cloud SQL, etc.), no selective exchange of routes, several quotas and limits shared between VPCs in a peering group
|
||||
- [Multi-NIC appliances](https://cloud.google.com/architecture/best-practices-vpc-design#multi-nic) (used here to connect the trusted landing and untrusted VPCs) and multi-NIC appliances with NCC/BGP support implemented [here](../2-networking-e-nva-bgp/)

|
||||
- Pros: provides additional security features (e.g. IPS), potentially better integration with on-prem systems by using the same vendor
|
||||
- Cons: complex HA/failover setup, limited by VM bandwidth and scale, additional costs for VMs and licenses, out of band management of a critical cloud component

The Cloud Routers (connected to the VPN gateways in the trusted VPC) are configured to exclude the default advertisement of VPC ranges and they only advertise their respective aggregate ranges, via custom advertisements. This greatly simplifies the routing configuration and avoids quota or limit issues, by keeping the number of routes small, instead of making it proportional to the subnets and to the secondary ranges in the VPCs.

VPCs are defined in separate files, one for `landing` (landing and dmz), one for `prod` and one for `dev`.
|
||||
|
||||
These files contain different resources:
|
||||
|
||||
- **project** ([`projects`](../../../modules/project)): the "[host projects](https://cloud.google.com/vpc/docs/shared-vpc)" containing the VPCs and enabling the required APIs.
|
||||
- **VPCs** ([`net-vpc`](../../../modules/net-vpc)): manages the subnets, the explicit routes for `{private,restricted}.googleapis.com` and the DNS inbound policy for the trusted landing VPC. Non-infrastructural subnets are created leveraging resource factories. Sample subnets are shipped in [data/subnets](./data/subnets) and can be easily customized to fit users' needs. [PSA](https://cloud.google.com/vpc/docs/configure-private-services-access#allocating-range) are configured by the variable `psa_ranges` if managed services are needed.

The connectivity between on-premises and GCP (the trusted landing VPC) is implemented with Cloud HA VPN ([`net-vpn`](../../../modules/net-vpn-ha)) and defined in [`vpn-onprem.tf`](./vpn-onprem.tf). The file implements a single logical connection between on-premises and the trusted landing VPC, both in `europe-west1` and `europe-west4`. The relevant parameters for its configuration are found in the variables `vpn_onprem_primary_config` and `vpn_onprem_secondary_config`.

|
||||
|

BGP sessions for trusted landing to on-premises are configured through the variable `vpn_onprem_configs`.

### Firewall
|
||||
|
||||
**VPC firewall rules** ([`net-vpc-firewall`](../../../modules/net-vpc-firewall)) are defined per-vpc on each `vpc-*.tf` file and leverage a resource factory to massively create rules.
|
||||
To add a new firewall rule, create a new file or edit an existing one in the `data_folder` directory defined in the module `net-vpc-firewall`, following the examples of the "[Rules factory](../../../modules/net-vpc-firewall#rules-factory)" section of the module documentation. Sample firewall rules are shipped in [data/firewall-rules/landing-untrusted](./data/firewall-rules/landing-untrusted) and in [data/firewall-rules/landing-trusted](./data/firewall-rules/landing-trusted), and can be easily customized.

||||
|
||||
**Hierarchical firewall policies** ([`folder`](../../../modules/folder)) are defined in `main.tf` and managed through a policy factory implemented by the `net-firewall-policy` module, which is then applied to the `Networking` folder containing all the core networking infrastructure. Policies are defined in the `rules_file` file, to define a new one simply use the [firewall policy module documentation](../../../modules/net-firewall-policy/README.md#factory)".

The "landing zone" is divided into two VPC networks:

- the trusted VPC: the connectivity hub towards other trusted networks
|

- the untrusted VPC: the connectivity hub towards any other untrusted network

### NCC, NVAs and BGP sessions
|
||||
|
||||
The VPCs connect through two sets of sample NVA machines: one per region, each containing two instances. The appliances run [Container-Optimized OS](https://cloud.google.com/container-optimized-os/docs) and a container with [FRRouting](https://frrouting.org/).
|
||||
|
||||
We levarage NCC-RA to allow the NVAs to establish BGP sessions with Cloud Routers in the untrusted and in the trusted VPCs. This allows Cloud Routers to advertise routes to the NVAs, and the NVAs to announce routes to the Cloud Router, so it can program them in the VPC.
|
||||
We leverage NCC-RA to allow the NVAs to establish BGP sessions with Cloud Routers in the untrusted and in the trusted VPCs. This allows Cloud Routers to advertise routes to the NVAs, and the NVAs to announce routes to the Cloud Router, so it can program them in the VPC.
|
||||
|
||||
Specifically, each NVA establishes two BGP sessions (for redundancy) with the the Cloud Router deployed in the VPC and in the subnet where the interface of that VM is attached to.
|
||||
|
||||
**Cloud Routers in the untrusted VPC advertise the default route (0.0.0.0/0) to the NVAs**. The NVAs advertise the route to the Cloud Routers in the trusted VPC. These dynamic routes are then imported through VPC peerings in the spokes.
|
||||
**Cloud Routers in the DMZ VPC advertise the default route (0.0.0.0/0) to the NVAs**. The NVAs advertise the route to the Cloud Routers in the landing. These dynamic routes are then imported through VPC peerings in the spokes.
|
||||
|
||||
**Cloud Routers in the trusted hub adverts to the NVAs** all the subnets of the trusted VPCs. This includes the regional subnets and the cross-regional subnets. The NVAs manipulate the route costs (MED) before advertising them to the Cloud Routers in the untrusted VPC. This is done to guarantee symmetric traffic paths (more [here](https://medium.com/google-cloud/gcp-routing-adventures-vol-2-enterprise-multi-regional-deployments-in-google-cloud-3968e9591d59)).

|

|
||||
NVAs establish **extra BGP sessions with both cross-regional NVAs**. In this case, the NVAs advertise the regional trusted routes only. This allows cross-spoke (environment) traffic to remain also symmetric (more [here](https://medium.com/google-cloud/gcp-routing-adventures-vol-2-enterprise-multi-regional-deployments-in-google-cloud-3968e9591d59)). We set these routes to be exchanged at a lower cost than the one set for the other routes.

|

- the NVAs exchange dynamic routes using BGP with Cloud Routers in the untrusted VPC, Cloud Routers in the trusted VPC and cross-regional NVAs. This allows VMs in different environments and different regions to communicate.

The Cloud Routers (connected to the VPN gateways in the trusted VPC) are configured to exclude the default advertisement of VPC ranges and they only advertise their respective aggregate ranges, via custom advertisements. This greatly simplifies the routing configuration and avoids quota or limit issues, by keeping the number of routes small, instead of making it proportional to the subnets and to the secondary ranges in the VPCs.

### Firewall
|

|
||||
**VPC firewall rules** ([`net-vpc-firewall`](../../../modules/net-vpc-firewall)) are defined per-vpc on each `vpc-*.tf` file and leverage a resource factory to massively create rules.
|
||||
To add a new firewall rule, create a new file or edit an existing one in the `data_folder` directory defined in the module `net-vpc-firewall`, following the examples of the "[Rules factory](../../../modules/net-vpc-firewall#rules-factory)" section of the module documentation. Sample firewall rules are shipped in [data/firewall-rules/landing-untrusted](./data/firewall-rules/landing-untrusted) and in [data/firewall-rules/landing-trusted](./data/firewall-rules/landing-trusted), and can be easily customized.

|

|
||||
**Hierarchical firewall policies** ([`folder`](../../../modules/folder)) are defined in `main.tf` and managed through a policy factory implemented by the `net-firewall-policy` module, which is then applied to the `Networking` folder containing all the core networking infrastructure. Policies are defined in the `rules_file` file, to define a new one simply use the [firewall policy module documentation](../../../modules/net-firewall-policy/README.md#factory)". Sample hierarchical firewall rules are shipped in [data/hierarchical-ingress-rules.yaml](./data/hierarchical-ingress-rules.yaml) and can be easily customised.
