barriers first:
– Engage cross-functional teams in
the evaluation of alternatives
2. Don't assume that SDN is the only
way forward

Recommendations
No blanket solution to app performance issues:
– Tackle by environment and use case.
Never assume your job is complete:
– Application environments are constantly changing.
Network agility is a must:
– However, you can start small and expand and replicate success.
Follow the application flows!
