Container Network Interface

The Container Network Interface (CNI) is a set of standards and tools that enable containers—small, isolated software units—to connect securely and efficiently to a computer network. It ensures that each container has its own network identity, like an IP address, allowing them to communicate with other containers, servers, or the internet. Think of it as a bridge that seamlessly links individual containers to the overall network infrastructure, managing their network connections dynamically and automatically, which is essential for scaling, security, and management in modern cloud environments.
