What is a VPC?
A Virtual Private Cloud (VPC) is a private, isolated section of the AWS cloud where you can launch your AWS resources. It acts as a secure environment for your IoT devices, ensuring that all communications remain within a controlled network. By leveraging VPCs, you can:
- Define your own IP address range
- Create subnets for organizing resources
- Configure route tables and network gateways
- Implement security groups and access control lists
Why Use VPC for IoT?
VPCs are particularly beneficial for IoT because they provide:
- Enhanced security through isolation
- Scalability to accommodate growing IoT ecosystems
- Flexibility in managing network configurations
Raspberry Pi Overview
The Raspberry Pi is a low-cost, credit-card-sized computer that can be used for a variety of projects, including securely connecting remote IoT devices. Its versatility and ease of use make it an excellent choice for hobbyists and professionals alike. Key features of the Raspberry Pi include:
- Multiple GPIO pins for connecting sensors and actuators
- Support for various operating systems, including Linux
- Built-in Wi-Fi and Bluetooth capabilities
Choosing the Right Raspberry Pi Model
When selecting a Raspberry Pi for your IoT project, consider the following factors:
