When would you consider edge deployment, and what are its typical challenges?

• A. To centralize latency within a single data center; no challenges.
• B. To reduce latency by deploying to edge locations; challenges include management, security, and consistency across nodes.
• C. To increase latency for testing.
• D. It eliminates security concerns.

Answer: (B)

Edge deployment is considered when you want to reduce latency by bringing compute and services closer to where users or devices are located, placing workloads at edge locations rather than in a central data center. This proximity cuts the round-trip time, improving responsiveness for latency-sensitive workloads like real-time analytics, interactive apps, or IoT gateways. But distributing compute across many edge nodes introduces several common challenges: you must manage and orchestrate a large, diverse set of sites; security becomes more complex due to a larger attack surface and varied physical environments; and keeping data consistent and synchronized across all edge nodes can be difficult, leading to potential stale results or conflicts. Additional considerations include deploying updates across heterogeneous hardware, monitoring and troubleshooting at scale, ensuring reliable connectivity, and addressing data governance or residency requirements.
