Redundancy Design
Redundancy Design is a system architecture principle that involves incorporating duplicate or backup components, systems, or data paths to ensure reliability, fault tolerance, and high availability in case of failures. It is commonly applied in critical infrastructure, such as servers, networks, databases, and cloud services, to minimize downtime and data loss. This concept is fundamental in designing resilient systems that can withstand hardware malfunctions, software errors, or external disruptions.
Developers should learn and apply Redundancy Design when building systems where uptime, data integrity, and continuous operation are critical, such as in financial services, healthcare applications, e-commerce platforms, or cloud-based services. It is essential for meeting service-level agreements (SLAs), preventing single points of failure, and enhancing disaster recovery capabilities, ensuring that users experience minimal interruptions even during component failures.
