Episode notes
Programmability Defines Modern Networking
- The modern networking stack is defined by programmability, software-defined management, and flexibility.
- This shift enables developers to build and modify network services quickly, enhancing innovation and service delivery.
Overlay Networks Add Complexity
- Overlay networks are pervasive today due to their role in security and segmentation.
- However, they add complexity by encapsulating packets, which was uncommon in older networks.
Use Centralized Tools for Complex Devices
- Use centralized management platforms to view and troubleshoot complex firewall and security device configurations.
- Command line remains effective for simpler devices like switches, but GUIs help with multi-device visibility.
