How to Set Up a Raspberry Pi VPC Network?

Step 1: Installing the Operating System

Setting up a Raspberry Pi VPC network begins with installing the appropriate operating system. For most users, Raspbian (now called Raspberry Pi OS) is the go-to choice due to its stability and ease of use. To install the OS, download the latest version from the official Raspberry Pi website and use a tool like Balena Etcher to flash it onto an SD card. Once the OS is installed, insert the SD card into the Raspberry Pi and power it on.

During the initial boot, the Raspberry Pi will prompt you to configure basic settings such as Wi-Fi, locale, and user credentials. It’s essential to enable SSH (Secure Shell) access during this step, as it allows you to remotely manage the device. You can do this by navigating to the Raspberry Pi Configuration menu or using the `raspi-config` command in the terminal. Enabling SSH is particularly important for managing the VPC network, as it allows you to execute commands and deploy services from a remote machine.
