What is the primary advantage of a spine-leaf architecture over a traditional three-tier architecture in a modern data center network?

The primary advantage of a spine-leaf architecture over a traditional three-tier architecture in a modern data center network is improved scalability and reduced latency due to its flatter, more predictable network topology. In a traditional three-tier architecture, network traffic often traverses multiple layers (access, aggregation, core) to reach its destination, leading to increased latency and potential bottlenecks. Spine-leaf architecture, on the other hand, eliminates thes....
