SUMMARY
8. SMELL :: CONFIGURATION DRIFT
• Any change outside a baseline
configuration is considered a
configuration drift.
• Could be an accidental or incidental or
intentional.
• Early identification will minimize
impact and reduce the risks around
business continuity.
10. SMELL :: SYSTEMS ENTROPY
As a system is modified, its disorder, or entropy,
always increases.
• Similar to theories in software development, a
system that is used will be modified.
• When a system is modified, its complexity will
increase, provided that one is not actively working
to reduce complexity.
11. PRESCRIPTION :: SEPARATION OF CONCERNS
How can I build my web hosting business?
How can I manage my customer relationships? Data
How can I run my company's IT department? Center
How can I collaborate across the enterprise?
How can I view my corporate sales data? Software
How do I store & retrieve my inventory data?
How do I deploy my web services? Platform
How do I get the most of my IT and Infrastructure
personnel resources?
12. SMELL :: STAFFING ATROPHY
“Atrophy is the partial or complete
wasting away of a part of the body.
Causes include lack of exercise and/or
use”
15. PRESCRIPTION :: USE CONTINUOUS PROVISIONING
Consistent, repeatable builds encourage fast
deployment and consistently identical
systems without the burden of managing
images
A repeatable build improves product
quality, reduces the mundane tasks
and minimizes dependencies on key
people.

17. PRESCRIPTION :: CONTAINER PARTITIONING
Virtualization can reduce cost while also improving flexibility…
Cluster multiple physical servers to gain failover capabilities
Share resources across physical servers
