A rural manufacturing company wants to move all IT services, including the industrial control systems, to the cloud. Given this scenario, which of the following cloud services elements would be a…

Computing capacity flexibility is a primary benefit of cloud adoption, not a challenge, since cloud platforms provide dynamic scaling on demand.

Industrial control systems (ICS/SCADA) are engineered for isolated OT networks using proprietary protocols such as Modbus and DNP3, which were never designed for internet-facing cloud environments. Migrating them to the cloud exposes them to cyber threats, creates compliance challenges under frameworks like IEC 62443 and NERC CIP, and introduces latency risks that can affect real-time industrial operations. The fundamental mismatch between ICS security requirements and cloud architecture makes this the primary deployment challenge.

Integrated Services Digital Network (ISDN) is a legacy circuit-switched telephony standard that has no direct relevance to cloud service deployment challenges.

While rural broadband availability is a valid concern, it is a general network infrastructure limitation rather than a cloud services element specific to this deployment scenario.
