Redundancy in cloud computing can be implemented at different levels of the network depending on the cloud computing model and business requirements. Device level redundancy, for example, involves having multiple network devices of the same type and function, such as routers, switches, or firewalls. This can help you avoid single points of failure, improve load balancing, and increase fault tolerance. Link level redundancy refers to having multiple network connections between devices, such as cables, ports, or channels. This can help you increase bandwidth, reduce latency, and enhance resiliency. Finally, site level redundancy involves having multiple network locations where your resources are hosted, such as data centers, regions, or zones. This can help you improve scalability, availability, and disaster recovery. Techniques such as clustering, failover, mirroring, aggregation, bonding, multipathing, replication, synchronization or backup can be used to achieve these levels of redundancy in cloud computing.
