D.

The customers of the Multitenant IaaS cloud solution should be the most concerned about the vulnerability announced, which allows a malicious user to gain root privileges on other virtual machines running within the same hardware cluster.

Explanation:

  • Single-tenant private cloud: A private cloud is owned and operated by a single organization, which has full control over the cloud infrastructure. As a result, the organization is responsible for implementing its own security measures and managing its own vulnerabilities. Therefore, the customers of a single-tenant private cloud should not be as concerned about the vulnerability announced as customers of other cloud solutions.

  • Multitenant SaaS cloud: In a SaaS (Software as a Service) cloud, the service provider is responsible for the security of the cloud infrastructure and the applications hosted within it. The customers of a SaaS cloud do not have direct access to the underlying infrastructure, so they should not be affected by the vulnerability announced.

  • Single-tenant hybrid cloud: A hybrid cloud is a combination of a private cloud and a public cloud, which allows organizations to use the public cloud for non-sensitive workloads while keeping sensitive data and applications in their private cloud. Customers of a single-tenant hybrid cloud should have control over their own private cloud infrastructure and be responsible for implementing their own security measures.

  • Multitenant IaaS cloud: In an IaaS (Infrastructure as a Service) cloud, the cloud provider is responsible for the security of the cloud infrastructure, while the customers are responsible for securing their own virtual machines and applications. Therefore, customers of a Multitenant IaaS cloud should be the most concerned about the vulnerability announced, as it can potentially allow an attacker to gain root privileges on other virtual machines running on the same hardware cluster.

  • Multitenant PaaS cloud: In a PaaS (Platform as a Service) cloud, the cloud provider is responsible for the security of the cloud infrastructure and the platform services provided. The customers are responsible for securing their own applications and data. Similar to SaaS, customers of a PaaS cloud do not have direct access to the underlying infrastructure, so they should not be affected by the vulnerability announced.

  • Single-tenant public cloud: In a public cloud, the cloud provider is responsible for the security of the cloud infrastructure, while the customers are responsible for securing their own virtual machines and applications. Customers of a single-tenant public cloud should have control over their own virtual machines and be responsible for implementing their own security measures.

In summary, the Multitenant IaaS cloud customers should be the most concerned about the vulnerability announced as they are responsible for securing their own virtual machines and applications running on the cloud infrastructure.
