Overview of IoT and AWS VPC

IoT, or the Internet of Things, refers to the network of physical devices embedded with sensors, software, and connectivity that allow them to exchange data. AWS VPC (Virtual Private Cloud) is a service provided by Amazon Web Services that allows users to create an isolated virtual network in the cloud. By leveraging AWS VPC, you can securely connect remote IoT devices to your cloud infrastructure.

Why Use AWS VPC for IoT?

AWS VPC offers several advantages for IoT deployments:

Enhanced security through network isolation.
Controlled access to IoT devices via private subnets.
Scalability to accommodate growing numbers of IoT devices.

Setting Up Raspberry Pi

Raspberry Pi serves as a versatile platform for IoT projects, offering a cost-effective solution for running applications and connecting to cloud services.

Steps to Set Up Raspberry Pi

To set up Raspberry Pi for IoT, follow these steps:

Download the Raspberry Pi OS from the official website.
Flash the OS onto an SD card using software like Balena Etcher.
Insert the SD card into the Raspberry Pi and power it on.
Connect to the Raspberry Pi via SSH or directly using a monitor and keyboard.

Configuring AWS VPC

Configuring AWS VPC involves setting up a virtual network where your IoT devices can securely communicate.

Key Components of AWS VPC

VPC CIDR Block: Defines the IP address range for your network.
Subnets: Divides the VPC into smaller segments for better management.
Security Groups: Acts as a virtual firewall to control inbound and outbound traffic.

Establishing Secure Connections

Securing the connection between Raspberry Pi and AWS VPC is crucial to protect sensitive data.
