6. Monoculture paper summary
Environment
Can be global
e.g. all MS Windows everywhere
Can be local
e.g. a business using Linux for all desktops
Can be software or hardware
MS Office
Cisco network equipment
Intel processors
Gaming systems: PS4s or Xbox One

7. Monoculture vs. Standards vs. Protocols
Standards and Protocols are not monocultures
Example:
TCP is a protocol:
Describes how to send packets
Different systems use different software to implement the protocol
An error in one implementation would not be seen in a different system
SSH is a protocol that is an internet standard
OpenSSH is one implementation of that standard
There are others
Intel could be a monoculture
Error in the design of a processor would be seen in all systems using that processor

8. Monoculture Pluses Negatives Uniformity  ease of use Transferability
Lower training costs
Transferability
Easy of interoperability between programs and data
Economy of scale
Negatives

9. Monoculture Monoculture is not an MS problem only
Can be any exclusive system
Game platforms
Network infrastructure
Best?
No best solution
Choose for the conditions
Business is "uniform"
Monoculture may be the best solution
Ensure to address potential problems  $$$
Business has various needs

Spend the $$$ to support the more complex environment
Still need to worry about security
