Topology architectures and deployment models: two-tier, three-tier, spine-leaf, WAN, SOHO, on-premises, and cloud

By the end you’ll be able to

• Compare two-tier and three-tier campus architectures, including the distribution of access, distribution, and core functions.
• Describe spine-leaf architecture and explain its use in modern data center environments for predictable east-west connectivity.
• Identify the purpose of WAN architectures in connecting geographically separated networks over service-provider infrastructure.
