What is a Virtual Private Cloud?

A VPC (Virtual Private Cloud) is basically a logically isolated segment in the public cloud and offers users their own private, secure network environment. While shared infrastructure is there between other tenants, VPC’s utilize mechanisms of network isolation generated by private IP addresses, subnets, and virtual firewalls for the creation of a separate and secure slot.  

VPCs enable running applications and data storage over one entity with higher security and flexibility. Subnetting is an important aspect of a VPC, dividing it into small network areas.  

Also, route tables control incoming and outgoing traffic between such subnets and other networks. In addition, security groups and NACLs are used for virtual firewalls controlling incoming as well as outgoing traffic.

VPC can be tailored to network-specific requirements using IP address ranges, VPN setting, and integration of on-prem data centers. VPC peering also supports connectivity among multiple VPCs, enabling secure cross-VPC communications without utilizing the public domain.  

VPCs form the heart of most hybrid and multi-cloud strategies, providing managed private networks with scalability and pricing advantages of the cloud.
