SDN adoption comes with challenges.
Technical:
- Controller scalability. Test at scale before production.
- Latency. Controller round-trips add delay.
- Interoperability. OpenFlow implementations vary.
Operational:
- Skills gap. Network engineers need training.
- Troubleshooting. New tools required.
- Integration with existing monitoring and security tools.
Organizational:
- Cultural resistance to losing direct device access
- Changed vendor relationships
Start small. Prove value. Expand gradually.
