Failover Automation
Failover automation is a system design concept and operational practice that involves automatically switching to a redundant or standby system when the primary system fails, ensuring high availability and minimal downtime. It typically uses monitoring tools, scripts, or orchestration platforms to detect failures and trigger the transition without human intervention. This is critical in distributed systems, cloud environments, and mission-critical applications where reliability is paramount.
Developers should learn and implement failover automation to build resilient systems that can withstand hardware failures, network issues, or software crashes, especially in production environments like e-commerce, financial services, or healthcare where downtime leads to significant losses. It reduces manual recovery time, improves service-level agreements (SLAs), and is essential for disaster recovery plans in cloud-native architectures using microservices or containers.
