A financial institution is in the process of migrating its operations to the cloud to enhance its service delivery. The institution deals with highly sensitive customer data and must adhere to stringent regulatory standards, including GDPR for data protection and PCI DSS for payment security. The cloud solution must provide robust security measures, complete control over data, and the flexibility to scale resources dynamically during high transaction volumes. Furthermore, due to specific regulatory mandates, certain workloads need to remain on-premises. Given these comprehensive requirements, which cloud deployment model would MOST effectively satisfy the institution's needs? (Choose one option from A to D)
A
Public cloud, as it offers unparalleled scalability and ease of management, along with pre-configured compliance certifications that cover all regulatory requirements without the need for additional configurations.
B
Private cloud, which provides superior security and data control, making it perfectly suited for sensitive data and high-performance applications, though scaling may necessitate further investment in infrastructure.
C
Hybrid cloud, blending the security and control advantages of a private cloud with the scalability benefits of a public cloud. This model enables the institution to keep sensitive data on-premises for compliance while utilizing public cloud resources for scaling during peak demand.
D
All cloud deployment models are equally capable of meeting the institution's requirements in terms of security, scalability, and compliance, making cost the sole deciding factor.
