What is IoT?
IoT, or the Internet of Things, refers to the network of physical objects embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet. These objects range from household appliances to industrial machines, all designed to collect and share data to improve efficiency and decision-making.
Key characteristics of IoT include:
- Interconnectivity: Devices communicate with each other and the cloud.
- Data Collection: Sensors gather data from the environment or user interactions.
- Automation: Devices can perform tasks without human intervention.
- Scalability: IoT systems can expand to accommodate more devices and users.
IoT has transformed industries such as healthcare, agriculture, and manufacturing by enabling real-time monitoring, predictive maintenance, and enhanced user experiences. However, the increasing number of connected devices also raises concerns about security and privacy, making secure connections essential.
Understanding VPC
A Virtual Private Cloud (VPC) is a secure, isolated private cloud hosted within a public cloud environment. It allows users to run their applications and store data in a virtual network that is logically isolated from other networks. VPCs are widely used in IoT projects to ensure secure communication between devices and services.
Key features of VPCs include:
