Data centre infrastructure course description
This course provides a foundation in data centre
infrastructure technologies. It begins with a tour of
virtualisation and the impact of this on the network
before moving on to the spine and leaf design, how it
works and how to scale. Layer 2 technologies enabling
this architecture are studied in terms of the impact on
the data centre. The course then progresses onto how
Layer 3 technologies such as BGP, EVPN and VXLAN
are used in data centre networks. The course then
studies interconnecting data centres finishing with a
section on automation and orchestration of both
underlay and overlay networks.
