 Understanding the Requirements:

The customer wants to modernize a legacy application into a cloud-native application.

The new application must have a web-based user interface (UI) that runs closer to end users.

Critical data must be kept on-premises for security, compliance, or performance reasons.

 Deployment Model Options:

Cloud Service On-Premises (A): This typically refers to running cloud-like services in an on-premises data center, which doesn't satisfy the requirement of running the UI closer to end users in the public cloud.

Hybrid Cloud (B): This model integrates both public cloud and on-premises resources, allowing the UI to run in the public cloud for proximity to end users, while critical data remains on-premises.

Public Cloud Only (C): This would mean hosting everything in the public cloud, which does not meet the requirement of keeping critical data on-premises.

Traditional IT On-Premises Only (D): This would keep all components on-premises, not leveraging the benefits of the public cloud for the web-based UI.

 Why Hybrid Cloud (B) is the Best Fit:

Flexibility and Proximity: A hybrid cloud allows the deployment of the web-based UI in the public cloud, ensuring low latency and high performance for end users.

Data Sovereignty and Compliance: Critical data can remain on-premises, satisfying security and compliance needs.

Best of Both Worlds: It combines the scalability and flexibility of the public cloud with the control and security of on-premises infrastructure.
