What is the term for a situation where a customer is unable to migrate to another provider due to constraints?

The correct term for the situation where a customer is unable to migrate to another provider due to various constraints is known as Vendor Lock-In. This concept encapsulates the challenges faced by customers who have become heavily dependent on a specific vendor’s services, tools, or technologies.

Vendor Lock-In typically occurs when a customer has made significant investments in a specific cloud service provider’s infrastructure, applications, and solutions, making it difficult to switch to another provider without incurring substantial costs or encountering technical challenges. These constraints may include proprietary technologies, unique data formats, or the complexity involved in transferring data and applications to a different platform.

In contrast to the other terms mentioned, Vendor Lock-In specifically addresses the dependency that arises from the customer-vendor relationship, emphasizing the impact of such a dependency on the customer's ability to change providers. Other options, while related to cloud computing, do not effectively capture the specific nature of constraints that limit a customer's migration choices.
