A financial institution is planning to migrate its operations to the cloud to leverage the benefits of cloud computing. The institution handles highly sensitive customer data and must comply with strict regulatory standards such as GDPR and PCI DSS. It requires a cloud deployment model that offers robust security features, complete control over data, and the ability to dynamically scale resources to manage varying transaction volumes during peak periods. Additionally, the institution aims to optimize operational costs without sacrificing security or performance. Considering these requirements, which of the following cloud deployment models would BEST meet the institution's needs? Choose one option.
A
Public cloud, as it provides unmatched scalability and cost-efficiency, ideal for handling peak loads, though the shared security model might not fully address the concerns for sensitive data.
B
Private cloud, offering the highest level of security and data control, customized to meet strict compliance requirements, but potentially at higher costs and with limited elasticity for scaling during peak times.
C
Hybrid cloud, blending the security and control of a private cloud for sensitive data with the scalability and cost-effectiveness of a public cloud for less sensitive operations, thus addressing both security and scalability needs despite increased management complexity.
D
Community cloud, tailored for organizations with similar regulatory needs, providing a shared infrastructure that balances security, scalability, and cost, but may offer less customization and control.
