Here's a more detailed breakdown of the VPC Setup and Configuration:

Choose a Cloud Provider: Select a provider like AWS, Google Cloud, or Azure that offers VPC services. Each provider has its own console and interface.
Create a VPC:
- Log into your cloud provider's console.
- Navigate to the VPC section (usually found under networking).
- Create a new VPC. Give it a name and specify an IP address range (CIDR block). This range defines the IP addresses used within your VPC (e.g., 10.0.0.0/16).
Configure Subnets:
- Within your VPC, create subnets. Subnets divide the VPC's IP address range into smaller networks.
- Specify the subnet's IP address range and choose an availability zone (if applicable). Availability zones are isolated locations within a region.
Configure Route Tables:
- Route tables determine how network traffic is routed within your VPC.
- Create a route table and associate it with your subnets.
- Add routes to allow traffic to the internet (if needed) and between your subnets.
Configure Security Groups:
- Security groups act as virtual firewalls, controlling inbound and outbound traffic to your Raspberry Pi.
- Create a security group and associate it with your Raspberry Pi's network interface.
- Configure inbound rules:
  - Allow SSH (port 22) traffic from your remote device's IP address or a specific CIDR block.
  - This is crucial for secure access. If you allow SSH from the entire internet (0.0.0.0/0), your Raspberry Pi will be vulnerable to attacks.
- Configure outbound rules:
  - Allow all outbound traffic from your Raspberry Pi (default setting).
Install and Configure SSH on the Raspberry Pi:
- Ensure SSH is enabled on your Raspberry Pi. You can usually enable it via the Raspberry Pi configuration tool or by editing the `/etc/ssh/sshd_config` file.
- Configure the SSH server to use a strong password or, preferably, SSH keys for authentication.
