Which statement best describes a hybrid cloud model?

The hybrid cloud model is best described by the combination of on-premises infrastructure and public cloud services. This approach allows organizations to utilize their existing on-premises resources while also taking advantage of the scalability and flexibility offered by public cloud providers. By integrating these two environments, businesses can optimize their workload distribution, adjust to varying demand levels, and create a more resilient IT strategy.

This model provides the benefits of both worlds: sensitive data can be kept on-premises for security reasons, while less sensitive workloads can be processed in the public cloud. This flexibility enables organizations to scale resources efficiently and respond to changing business needs without being confined to a single environment.

In contrast, a purely on-premises infrastructure would lack the elasticity and cost-effectiveness of cloud computing. Using only public cloud resources wouldn’t leverage existing infrastructure investments. Similarly, a mix of on-premises and private cloud resources does not capture the essence of integrating public cloud services with on-premises assets, which is crucial to defining a hybrid cloud model.
