Which of the following is a common cloud challenge?

• A. Unpredictable cost
• B. Vendor lock-in
• C. Security concerns
• D. Policy concerns

Answer: (B)

Vendor lock-in is a common cloud challenge. When you build and run workloads using a provider’s managed services, APIs, and data formats, moving to another provider—or bringing services in-house—can become costly and complex. Proprietary interfaces and tools may not translate cleanly to a different platform, data may need transformation to export, and egress or re-architecting fees can add up. Contract terms and feature gaps can also make switching feel risky or disadvantageous, which reduces flexibility and bargaining power over the long term. Because these factors directly affect portability and overall cost of ownership across cloud environments, this issue stands out as a frequent and significant concern.

Unpredictable costs can arise, but they’re often manageable with governance, visibility, and budget controls. Security concerns are important, yet cloud environments share responsibility with users and security practices can be strengthened across any platform. Policy concerns involve governance and compliance, which are essential but don’t inherently drive the same level of dependency on a single cloud ecosystem as lock-in does.
