What term refers to a network fault tolerance technique within a cloud environment?

Redundancy is a key network fault tolerance technique used within a cloud environment to ensure high availability and reliability. By implementing redundancy, critical components within a network are duplicated so that if one component fails, another can take its place without disrupting services. This capability is crucial in cloud computing, where downtime can lead to significant losses in productivity and revenue.

In cloud environments, redundancy can be applied to various elements, such as servers, network connections, and storage systems. For example, having multiple servers hosting the same application ensures that if one server goes down, the application remains accessible through another server. This not only enhances uptime but also contributes to a seamless user experience.

In contrast, while replication involves creating copies of data to safeguard against loss, it doesn't directly address the network structures themselves. Load balancing distributes workloads across multiple resources to optimize resource use and enhance responsiveness but does not inherently include redundancy mechanisms. Failover refers to the process of switching to a standby component when a failure is detected, which is an aspect of redundancy but not the broader term that encompasses the entire strategy.
