Final thoughts!

One thing you can say about containers is that they are a major change in how we view network components. When servers started as bare-metal entities in the data-center it was a physical box with a cable attached to it that had a specific IP address and it pretty much never moved!

Then Virtualization kicked into full gear and now those big metal boxes became virtualized machines that sat on those same big metal boxes but now there where many of them, and then they moved around the network like crazy. To adapt that world network equipment makersmade faster switches, provided the ability to be able to observe the virtual devices from the network perspective. Orchestrators kicked into action also helping both the network administrator and then the application teams manage the explosion of virtualized resources that made consumption of expensive compute hardware more efficient.

Then came cloud. And with cloud we learned that velocity of deploying resources was a critical factor. Developer teams in companies wanted to be able to use compute resources faster than what data-center teams could deliver. In that mix containers and orchestration provided a way to quickly develop micro-services on-premise. This makes it possible to develop quicker, repeatable without errors and in a way that makes it possible to use the same deployment provisioning code in different platforms, like googles own cloud.

The hard part comes how do you manage policy in a network that has entities that are stateless and are created or deleted in seconds. You can adopt a policy of laissez-faire but that can lead to dangerous consequences in the security space.

We in Cisco believe in the following:

ACI provides you with the right tooling and visibility to give your kubernetes cluster an edge in operational control, visibility and security. The combination of both platforms provides you the ability to create a private cloud for micro-services that uses the same technology as google uses to run the biggest cloud in the world.
