Segmented Network
A segmented network is a network architecture where a larger network is divided into smaller, isolated subnetworks (segments) to improve security, performance, and manageability. This is typically achieved using devices like routers, firewalls, or VLANs to control traffic flow between segments. It helps contain potential security breaches, reduce broadcast traffic, and organize network resources logically.
Developers should learn about segmented networks when designing or securing applications in enterprise or cloud environments to ensure compliance, enhance security, and optimize performance. Use cases include isolating sensitive data (e.g., financial or healthcare systems), separating development and production environments, and managing large-scale networks in data centers or IoT deployments.
