Introduction to IoT and VPC

The Internet of Things (IoT) refers to a network of interconnected devices that communicate and exchange data over the internet. These devices can range from simple sensors to complex industrial machines. IoT has revolutionized various industries by enabling real-time data collection, analysis, and automation. However, managing IoT devices securely and efficiently requires a robust network infrastructure.

A Virtual Private Cloud (VPC) is a secure, isolated private cloud hosted within a public cloud. It allows users to run their applications and store data in a virtual network that is isolated from other users. VPCs offer several advantages, including enhanced security, scalability, and flexibility. By integrating IoT devices with a VPC, you can ensure secure communication, centralized management, and seamless integration with cloud services.

Why Use a VPC for IoT?
