38. The only way you can truly leverage NSX is if you’re running the VMware hypervisor. From there,
you can control East-West routing, the automation of virtual networks, routing/bridging services
for VMs, and other core networking functions. If you’re a VMware shop hosting a large number of
VMs and are caught up in the complexities of virtual network management, you absolutely need to
look at NSX. However, there are some limitations. First of all, your levels of automation are limited
to virtual networks and virtual machines. There’s no automation for physical switches.
Furthermore, some of the L4-L7 advanced network services are delivered through a closed API, and
might require additional licensing. Ultimately, if you’re focused on virtualization and your
infrastructure of choice revolves around VMware, NSX may be a great option. With that in mind,
here are two more points to be aware of: If you have a super simple VMware deployment with
little complexity, you’ll probably have little need for NSX. However, if you have a sizeable VM
architecture with a lot of VMware networking management points, NSX can make your life a lot
easier.

39. This is a truly powerful model capable of abstracting the networking layer and integrating core
services with your important applications and resources. With this kind of architecture, you can
create full automation of all virtual and physical network parameters through a single API.
Furthermore, you can integrate with legacy workloads and networks to control that traffic as well.
And yes, you can even connect non-Cisco physical switches to get information, on the actual device
and what it’s working with. Furthermore, partnerships with other vendors allow for complete
integrations. That said, there are some limitations. Obviously, the only way to get the full benefits
from Cisco’s SDN solution is by working with the (sometimes not entirely inexpensive) Nexus line of
switches. Furthermore, more functionality is enabled if you’re running the entire Cisco fabric in
your data center. For some organizations, this can get expensive. However, if you’re leveraging
Cisco technologies already and haven’t looked into ACI and the APIC architecture, you should.

Points to highlight :
Often policies are created and defined in isolation (different sources) with different languages, tooling and required intent
These policy points will still exist however when we define in advance of the enforcement – working across teams in a highly collaborative way
We can now insatiate that policy as required without having to invoke the ‘human chain’, in a quick and agile manner
This is what ACI delivers..
