👉 Replica computing is a distributed computing paradigm where multiple identical copies of data or services are maintained across different physical locations to enhance reliability and fault tolerance. When a computation fails in one replica, the system can automatically switch to another replica with the same data or service, ensuring continuous operation without significant downtime. This approach is particularly useful in critical applications where data integrity and availability are paramount, such as financial transactions, healthcare systems, and cloud services. By leveraging the redundancy of multiple replicas, replica computing minimizes the risk of data loss and service disruption, providing a robust solution for maintaining system availability and reliability.
