SDDC systems might include one or more layers of compute, an overlay network, and multiple storage types. The physical network must be able to interact with all three components. In addition, SDDC systems deploy visibility and troubleshooting tools for the VMware administrator. Thus, visibility of the physical network must extend into the SDDC tools for consistent operations and troubleshooting across both virtualization and network domains.
Networks must provide visibility into VMs and east-west traffic across VMs. They must also deliver network service connectivity easily. Emerging cloud-native applications require rapid application and services deployment, which requires network operations to be more automated and less dependent on manual CLI and limited UI workflows. Thus, automation across physical and virtual networks becomes a critical aspect of the SDDC automated infrastructure. In addition, gaining visibility across physical and virtual networks is becoming paramount for network and VMware administrators because traditional network troubleshooting is challenging.
