32nd rule to measure complexity + 6 hyperscale network design rules

If you’ve studied computer science then you know there are algorithms that calculate “complexity.” Unfortunately, these have little practical use for data center operators.  My complexity rule does not require a PhD:

The 32nd rule: If it takes more than 30 seconds to pick out what would be impacted by a device failure then your design is too complex.

6 Hyperscale Network Design Rules

  1. Cost Matters
  2. Keep Networks Flat
  3. Filter at the Edge
  4. Design Fault Zones
  5. Plan for Local Traffic
  6. Offer load balancers (to your users)

Sorry for the teaser… I’ll be able to release more substance behind this list soon.   Until then comments are (as always) welcome!
