Concerns with Multicloud Strategy and Cloud Provider Migration

C.

When a company develops a product using a cloud provider's PaaS platform and many of the platform-based components within the application environment, they are essentially building their product on top of that cloud provider's infrastructure. This can lead to a concern known as vendor lock-in.

Vendor lock-in occurs when a company becomes too dependent on a specific vendor's services or products, making it difficult or expensive to switch to another vendor. In this scenario, the company would be concerned about the potential cost and effort of migrating to another cloud provider or adopting a multicloud strategy while also maintaining the functionality of their product.

In a multicloud strategy, a company utilizes multiple cloud providers to distribute their workloads, providing more flexibility and redundancy. However, if the company has developed their product using a specific cloud provider's PaaS platform and components, they may face challenges with compatibility, integration, and management when utilizing a multicloud strategy or migrating to another cloud provider.

Therefore, the answer to this question is D. Vendor lock-in. While licensing, authentication providers, and service-level agreements are all important considerations when working with cloud providers, they are not the primary concerns in this scenario.
