In this episode Malcolm and Daren discuss the concept of Security as a principle of network design.  The original idea for this discussion came from a series of blog posts, and now we give them the Network Freestyle treatment!  As you put together a design for a network, what do you need to ensure that you address to provide an appropriate degree of security of the environment? How do you ensure you keep the bad guys away from your network crown jewels?

In this episode Malcolm and Daren discuss data centre design, covering the key building blocks required to deliver a modular and scalable solution.

The design topics covered throughout the discussion include the trusted, semi-trusted and untrusted zones of the data centre, design drivers and some scenarios relating to traffic flows to / from applications and services from the WAN and internet.  

Consequences of stateful devices in the failover path are also covered with some suggestions on how issues can be alleviated to avoid application outages.
