High-Availability Network What is a High-Availability Network? A high-availability network is designed to ensure continuous uptime and reliability by minimising the risk of downtime through redundancy, failover mechanisms, and robust infrastructure. Explanation These networks use multiple layers of redundancy, such as backup servers and diverse routing paths, to maintain performance even during failures. They are essential for mission-critical applications. Practical Example of a High-Availability Network An online retailer employs a high-availability network to ensure uninterrupted access to its e-commerce platform, even during peak shopping events.
