What does application portability refer to in hybrid cloud strategies?

Application portability in hybrid cloud strategies refers specifically to the ability to easily move applications across different environments without significant rework. This characteristic is essential because hybrid cloud setups often involve a combination of on-premises infrastructure and public cloud resources. With application portability, businesses can deploy their applications where they can best leverage the infrastructure's capabilities, whether that’s on a private cloud, public cloud, or a hybrid combination of both.

This flexibility allows organizations to optimize costs, improve performance, and enhance failover and disaster recovery options. It enables them to respond quickly to changing business needs without being locked into a single environment. Significant rework would create inefficiencies and could hinder the agility that businesses aim to achieve in a hybrid cloud setup.

Understanding application portability is crucial in the context of deploying and managing applications effectively across multiple environments, ensuring that businesses can adapt to new technologies and changing demands without extensive redevelopment efforts. This is why option B is the correct answer.
