Physical Infrastructure
Physical infrastructure refers to the tangible hardware components and facilities that form the foundation of computing and networking systems. This includes servers, data centers, networking equipment (routers, switches), storage devices, power supplies, cooling systems, and physical security measures. It provides the essential physical layer upon which software, applications, and services operate.
Developers should understand physical infrastructure when designing systems that require high availability, scalability, or specific performance characteristics, such as in on-premises deployments, hybrid cloud environments, or edge computing scenarios. Knowledge of physical components helps in capacity planning, disaster recovery, and optimizing hardware-software interactions for cost-efficiency and reliability.
