"environment requiring an on-premises and cloud-based storage solution"

o A. Hybrid cloud deployment model combines on-premises infrastructure with a public cloud. This allows the company to store sensitive and proprietary data on its own servers within Iceland while leveraging the scalability and cost benefits of the public cloud for less critical data. Since the data never leaves Icelandic borders in this scenario, it complies with the company's data residency requirements. o D. Private cloud: A private cloud is dedicated to a single organization. While it offers the highest level of security and control, it can be expensive to set up and maintain. If the company also needs to leverage the scalability of the public cloud for less sensitive data, a private cloud alone would not be the optimal solution.

The company has its headquarters in Iceland, and the data must always reside in that country.

D. Private cloud Here’s why: A private cloud is dedicated to a single organization and can be either on-premises or hosted by a third-party provider but within the organization’s control. It allows for customized security and compliance measures tailored to the organization's specific needs, which is crucial for handling sensitive and proprietary data. In this case, a private cloud can be set up to ensure that all data remains within Iceland, meeting the requirement for data residency. It also allows for integrating on-premises infrastructure with the cloud environment, providing the flexibility needed for a hybrid storage solution.

From Microsoft Azure website: “A hybrid cloud is a type of cloud computing that combines on-premises infrastructure—or a private cloud—with a public cloud. Hybrid clouds allow data and apps to move between the two environments… When computing and processing demand fluctuates, hybrid cloud computing gives businesses the ability to seamlessly scale up their on-premises infrastructure to the public cloud to handle any overflow—without giving third-party datacenters access to the entirety of their data.” The question does not state that the company needs rapid elasticity offered by hybrid cloud, only that the data is sensitive, proprietary, and must remain in-country. Private cloud meets all those needs.

Read the first sentence of the question. "requiring an on-premises and cloud-based storage solution". A hybrid model can also meet all these requirements

Private cloud include- Hybrid Cloud Integration: Some organizations opt for a hybrid cloud approach, which combines elements of both private and public clouds. This allows them to leverage the benefits of each model based on the specific requirements of their workloads. Private clouds can be deployed on-premises, where the infrastructure is owned and managed by the organization, or they can be hosted by a third-party provider, offering a dedicated cloud environment in an off-site data center.

Don't let the sensitive information statement fool you. A hybrid cloud is a cloud computing environment that uses a mix of on-premises, private cloud and third-party public cloud services with orchestration between these platforms.

Private cloud (given its dedicated nature for the specific needs of one organization and ability to ensure data stays in Iceland)

should be D

A private cloud allows the organization to have dedicated control over the infrastructure, ensuring that sensitive and proprietary data remains within the organization's own data center or a cloud provider's infrastructure dedicated solely to that organization. In this case, since the data must always reside in Iceland, a private cloud deployment would offer the necessary control and compliance with data location requirements.

Should be D

DDDDDD

Chat GPT Answer D: In this scenario, considering the company's requirement to keep sensitive and proprietary data within Iceland while utilizing both on-premises and cloud-based storage solutions, the most suitable cloud deployment model would be a "Private cloud." A Private cloud allows the organization to have dedicated control over its cloud infrastructure, ensuring data residency within Iceland and maintaining the highest level of security and privacy, which aligns with the company's sensitive and proprietary data requirements. It also provides the flexibility to integrate with on-premises resources as needed. The other options like Hybrid, Community, or Public clouds may not provide the same level of control and data residency guarantees as a Private cloud in this specific context.
