More customers are moving workload to Public Cloud infrastructure and expect to extend SD-WAN from remote sites to public cloud to guarantee SLA. There are multiple options offered by VMware, leveraging distributed VMware SD-WAN Gateways to establish IPSec towards public cloud private network or deploy virtual edge directly on Google Cloud Platform (GCP).
For small branch deployment that demand throughput less than 1G, single virtual edge can be deployed in the Private GCP network. For larger data center deployments that demand multi-gig throughput, hub clustering can be deployed.
This document illustrates a basic topology and a high-level workflow to deploy a virtual SD-WAN Edge (vVCE) on GCP. See Virtual Edge Deployment on GCP.
Prerequisites
- GCP account and login information.
- Familiarity with GCP networking concepts. For more information, see https://cloud.google.com/vpc/docs/overview.
- SD-WAN Orchestrator target and admin account to login.
GCP Machine Types
Bandwidth throughput and the number of network interfaces need to be considered when sizing the VMware SD-WAN Virtual Edge. The minimum number of network interfaces required is three (GE1, GE2, GE3).
