Which type of cloud model typically presents the most challenges to a cloud customer during the "destroy" phase of the cloud data lifecycle?

C.

With many SaaS implementations, data is not isolated to a particular customer but rather is part of the overall application.

When it comes to data destruction, a particular challenge is ensuring that all of a customer's data is completely destroyed while not impacting the data of other customers.

The "destroy" phase of the cloud data lifecycle refers to the process of securely and permanently removing data from cloud systems at the end of its useful life or when it is no longer needed. This phase is critical for maintaining data privacy, security, and compliance.

Out of the four types of cloud models mentioned in the question (IaaS, DaaS, SaaS, and PaaS), the one that typically presents the most challenges to a cloud customer during the "destroy" phase is IaaS (Infrastructure as a Service).

IaaS is a cloud computing model that provides customers with virtualized computing resources over the internet. This includes servers, storage, and networking components that customers can use to build their own cloud infrastructure. IaaS customers are responsible for managing and securing their own applications, data, and operating systems.

The "destroy" phase in IaaS can be challenging for customers because they are responsible for managing the entire infrastructure stack, including the underlying hardware and virtualization layers. This means that customers must ensure that all data is securely deleted from every component of the infrastructure, including virtual machines, storage devices, and network devices.

Furthermore, IaaS customers may need to comply with various regulations that require them to securely delete data at the end of its lifecycle. Failure to do so can result in legal and financial penalties.

In contrast, DaaS (Desktop as a Service), SaaS (Software as a Service), and PaaS (Platform as a Service) are cloud models where the cloud service provider is responsible for managing and securing the infrastructure, including data deletion. As a result, customers of these cloud models typically have less responsibility for the "destroy" phase and may face fewer challenges.
