# Subnets

> Use subnets to separate workload tiers and reduce accidental exposure inside a Nubis VPC.

## Subnets turn network intent into layout

Subnets help you divide a VPC into workload zones such as public entry, application runtime, and data services. This makes access control and operations easier to manage later.

## Common subnet patterns

* Public-facing services in one subnet
* Internal application services in another
* Data services kept in restricted private ranges

## Good subnet habits

* Keep public and private workloads separated.
* Leave room for future growth in your address plan.
* Align subnets with how your firewalls and load balancers will behave.
* Avoid rebuilding the subnet plan every time a new app arrives.
