7 Cloud Networking: Limitations 7

8 What can you control? Limitations Layer 7 App 1 App 1 Layer 6 Layer 5 Cloud Customer Layer 4 Layer 3 Limit of user access, control and visibility Layer 3 Cloud Service Provider Application Policies You MUST Control Cloud Layer 3 Network (minimal tenant features) Layer 2 Layer1 Hypervisor You Don t Control Hardware You Can t Get To Layer 0 8

9 Limitations Most companies are NOT Google Google Inc., taking a new approach to enterprise security, is moving its corporate applications to the Internet. In doing so, the Internet giant is fipping common corporate security practice on its head, shifting away from the idea of a trusted internal corporate network secured by perimeter devices such as frewalls, in favor of a model where corporate data can be accessed from anywhere with the right device and user credentials. The new model called the BeyondCorp initiative assumes that the internal network is as dangerous as the Internet.

21 Future thinking: Cloud networks for all 21

22 Future Thinking Overlays and NFV - everywhere IoT will not be the Internet of things - it will be the Internets of things. Organizations may run an entire IPv4 Internet overlay which trunks out on to the real Internet. The things will be very wary of the trunk. Its called the cloud because it is so far away. Today s construction allows yielding to the temptation that the hypervisor network will be able to do it all. Not a chance! Your overlay is my underlay! Intertwining overlays will be projected ever farther out to the edge as all IoT devices live in a fully virtualized world of (choose your metaphor) Cat in the Hat computing, or Turtles All the Way Down. 22

23 Conclusions With the advent of server virtualization, the OS became part of the application stack; hypervisor becomes new infra decision. Container mania sweeping the industry is another manifestation of customers wanting over the top infrastructure they control more completely than their public or private cloud vendor. With the ability to do network virtualization, A network, not THE network becomes part of the application stack - a network dedicated to the needs of the application. Network overlays and NFV within them are part of the over the top movement, allowing customers enhanced control and security. 23
