This chapter is focused on the network and security components of a cloud model. Network virtualization makes it possible to programmatically create, provision, and manage networks in a software-defined way, using the underlying physical network as a simple packet‐forwarding backplane. Network and security services in a software stage are distributed to hypervisors and attached to individual virtual machines (VMs) in accordance with networking and security policies defined for each connected application. In this chapter, we are going to cover how to migrate from legacy network architectures to a new network virtualization technique, network virtualization versus software-defined networking, and securing the data center by limiting lateral movement within the data center:
- Network virtualization and highlighting the benefits of...
