What is a potential risk if cloud data interoperability is not considered?

When cloud data interoperability is not carefully considered, a significant risk is the inability to switch providers easily. This means that organizations may become locked into a particular cloud service provider due to proprietary formats or incompatibility with other systems. If organizations cannot easily transfer their data to another provider or integrate with different platforms, they may face challenges when they want to change providers for reasons such as cost, service quality, or feature availability. This situation can lead to increased costs, operational inefficiencies, and a lack of flexibility, making it difficult for the organization to adapt to changing business needs or technological advancements.

The other answer choices do not accurately address the key issue of interoperability. Decreased file sizes and faster data transfer rates may improve performance, but they do not relate to the risks of vendor lock-in or switching barriers. Increased data accessibility is a positive outcome that can result from good interoperability, but it does not capture the potential drawbacks of not prioritizing interoperability in cloud strategy.
