Switchover

A switchover in information technology refers to the process of transitioning from one system, component, or resource to another, often done to ensure continuity of operations, enhance performance, or address a failure. It typically involves temporarily or permanently redirecting the flow of data, services, or resources from the primary source to a secondary or backup source.

Switchover scenarios vary widely, including:

Disaster Recovery: In case of a system failure or disaster, a switchover may occur to switch operations from a primary data center to a secondary one, ensuring business continuity.-        Load Balancing: To distribute traffic evenly and optimize resource usage, a switchover might redirect incoming network requests from one server or data center to another.

Software Updates: During software upgrades or maintenance, a switchover can occur to temporarily transfer operations to a redundant system, minimizing downtime.

Failover: In high-availability systems, switchover might be triggered automatically when the primary component experiences issues, ensuring uninterrupted service delivery.

Data Migration: When moving data between storage systems or platforms, a switchover might be necessary to ensure data integrity and minimal disruption.

Successful switchover execution is critical for maintaining service availability and minimizing disruptions. It often involves thorough planning, testing, and monitoring to ensure a smooth transition from the primary to the secondary system or resource.
