Private Networking and VPCs
A Virtual Private Cloud, or VPC, is your own private, isolated section of a public cloud. It lets your servers and services communicate securely with each other while keeping them shielded from the open internet.
This article explains why private networking matters for security and how it is arranged.
Your Own Walled Garden
Within a VPC you control the network layout, deciding which parts are reachable from the internet and which are strictly internal. A database, for example, can be placed so that only your application can reach it and nothing outside can.
Public and Private Subnets
- Public subnet: for resources that must face the internet, such as a web server.
- Private subnet: for resources that should never be directly reachable, such as databases.
Why This Matters
Keeping sensitive systems off the public internet dramatically reduces your attack surface. It is a foundational security measure that we build into every cloud environment by default.
Frequently Asked Questions
Does a VPC slow anything down?
No. Private networking is about isolation and security, not speed, and it has no meaningful impact on performance.
