Grow your Google Virtual Private Cloud with Subnetworks Non-disruptively

The premise of a public cloud networking is about securely meeting the demand of customers, to address this challenge, Google introducing “expandable subnetworks” capabilities.

“Subnetwork expansion” lets you “quickly and efficiently expand your subnetwork IP space without disrupting running services”—meaning more efficient control of network, as and when your network grow.

In addition, Google also allowing curtomers the extension of their Google Cloud Platform subnetwork both “geographically” and within an “existing region”. For this, you don’t have to make irreversible IP allocation planning decisions up front, the company stated.

The company explains further that previously also using “subnetwork capabilities” customer could extend their private space across additional regions as needed. But, now, with expandable subnetworks, “IP ranges of pre-configured subnetworks can be extended as well, without any impact to existing instances and workloads” —all without reconfiguring or recreating existing workloads.

For those not aware of Google Cloud Virtual Network, “It allows you to have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets and expansion of those subnets across regions and within region.”

GCP provides you with the elasticity to expand your network in the regions where your applications grow.

To illustrate the power of subnetworks, let’s consider three situations.

  • Specify deployment regions while enjoying a global private space now by customizing the IP ranges of networks with regional subnetworks.
    “Each subnetworks is configured regionally, covering between two and four different availability zones, depending on the region, allowing workload mobility across zones keeping a persistent IP address.”
  • Grow your Virtual Private Cloud with subnetworks in new regions easily by just adding new subnetworks in those regions within the same network by configuring a new IP range that’s non-contiguous with IP ranges in other regions.
  • Expand the size of your subnetworks in existing regions non-disruptively—Now, simply grow in each region as your business grows without additional planning, explained GCP team.

This network flexibility is the byproduct of Google’s SDN.
