Hints
- 💡Think 5G, CDNs, IoT hubs.
Common Pitfalls to Avoid
- ⚠️Underestimating the complexity of managing a large, distributed fleet of edge devices.
- ⚠️Neglecting robust security protocols for edge nodes, leading to vulnerabilities.
- ⚠️Failing to account for intermittent or lost network connectivity in application design.
- ⚠️Overlooking power constraints and computational limitations of edge hardware.
- ⚠️Assuming that edge processing can entirely replace cloud computing, rather than complementing it.
Potential Follow-up Questions
- ❓How do you update edge nodes at scale?
- ❓What about intermittent connectivity?
