Redundancy refers to the concept of having duplicate or multiple components that can take over each other's functions if one device fails. This improves the reliability and availability of systems by eliminating potential single points of failure.
In the server environment, redundancy can mean that there are several physical servers connected to the same network. If one server goes down, the others will be able to take over its workload without interruption in service. In addition, the disks can be duplicated so that data is replicated in multiple locations simultaneously, protecting against possible data damage or loss.
Within the network infrastructure, redundancy is often implemented through the use of switches and routers that have dual power supplies and multiple connection ports. Through this design, traffic can be rerouted automatically should a failure occur in any part of the network, minimizing downtime and ensuring continuous communication.
There are different types of redundant architectures depending on the needs and budget of the organization. Examples include active/active redundant configuration where all components are active during normal operation or active/passive where only one component is working while the other is on stand-by for backup purposes.
In summary, the redundancy within servers and networks provides a robust and reliable infrastructure by preventing system interruptions and reducing the risk of data loss. This is particularly important in mission-critical environments where continuity and availability are decisive factors.
