Networking

• VPCs:

  • A Virtual Private Cloud (VPC) network is a virtual version of a physical network that provides connectivity for your Compute Engine virtual machine (VM) instances, including Google Kubernetes Engine (GKE) clusters, App Engine flexible environment instances, and other Google Cloud products built on Compute Engine VMs.
  • You can configure native Internal TCP/UDP Load Balancing and proxy systems for Internal HTTP(S) Load Balancing with your VPC network.

  
• A VPC network connects to on-premises networks by using Cloud VPN tunnels and Cloud Interconnect attachments and distributes traffic from Google Cloud external load balancers to backends.

  • By default, every network has routes that let instances in a network send traffic directly to each other, even across subnets. In addition, every network has a default route that directs packets to destinations that are outside the network. Although these routes cover most of your normal routing needs, you can also create special routes that override these routes.
