Which factors should be considered when deciding to move to cloud services?

• A. Cost, security, compliance, data residency, performance, vendor lock-in, availability, migration effort, and exit strategy.
• B. Only cost.
• C. Only performance.
• D. Only vendor reputation.

Answer: (A)

Deciding to move to cloud services requires weighing a broad set of considerations, not just price. Cost isn’t only the sticker price; you need to look at total cost of ownership, including migration, integration, ongoing operations, data transfer, and potential downtime. Security and compliance matter because the cloud shifts responsibilities and you must ensure appropriate data protection, access controls, encryption, and alignment with regulations. Data residency is important since laws and sovereignty rules can require where data is stored or processed, which affects where you deploy services and how you architect your solution. Performance matters too, looking at latency, throughput, and how well the cloud setup scales for your workloads across regions and times of day. Vendor lock-in is a real consideration because different providers use different APIs and services; plan for portability if you might switch providers later. Availability encompasses reliability, disaster recovery, and the guarantees in SLAs, which influence how you design for continuity. Migration effort captures the complexity, timelines, and change management needed to move and rehost or redesign applications. Exit strategy ensures you can terminate the relationship smoothly, with data portability and clear terms for data return or destruction. Together, these factors ensure you balance cost with risk, compliance, and business continuity rather than focusing on a single aspect.
