Grid Infrastructure refers to a framework that enables the sharing of resources across multiple locations, allowing for efficient management and utilization of computing power, storage, and data. It connects various systems and devices, facilitating collaboration and resource allocation among users and organizations. This infrastructure is essential for large-scale computing tasks, such as those found in cloud computing and big data analytics. By integrating resources from different sources, Grid Infrastructure helps improve performance, reduce costs, and enhance scalability, making it a vital component in modern technology environments.
