One possible answer is:
A: Use cloud-native serverless services.
Cloud-native serverless services are a type of cloud computing that allows developers to build and run applications without having to manage servers, infrastructure, or scaling. Cloud-native serverless services can help the organization meet the requirements listed above, as they can:
* Minimize organizational infrastructure and comply with security standards. Cloud-native serverless services are fully managed by the cloud provider, which means the organization does not have to provision, configure, or maintain any servers or infrastructure. The cloud provider also handles the security aspects of the serverless environment, such as encryption, authentication, authorization, patching, and monitoring. The organization can focus on developing the application logic and rely on the cloud provider to meet the security standards12.
* Minimize organizational compliance efforts. Cloud-native serverless services can also help the organization reduce the compliance burden, as they can leverage the compliance certifications and attestations of the cloud provider. The cloud provider can ensure that the serverless environment complies with various regulations and standards, such as PCI DSS, HIPAA, GDPR, ISO 27001, etc. The organization can inherit the compliance posture of the cloud provider and avoid the hassle of auditing and validating their own infrastructure12.
* Focus on application development and increase speed to market. Cloud-native serverless services can also enable the organization to accelerate the development and delivery of their online product, as they can write code using their preferred programming languages and frameworks, and deploy it quickly and easily to the serverless environment. The serverless environment can automatically scale up or down based on the demand, ensuring high availability and performance. The organization can also integrate serverless services with other cloud services, such as databases, storage, analytics, etc., to create a full-stack application12.

Software as a service (SaaS) is a type of cloud service model that provides software applications over the Internet that are hosted and managed by a cloud service provider. Directory service federation is a type of authentication mechanism that allows users to access multiple systems or applications across different domains or organizations with a single login credential. Using a SaaS service with a directory service federation can help migrate an internal file server to the cloud and use a web-based interface to access and manage the files, as it can eliminate the need for maintaining an on-premises file server and enable seamless and secure access to cloud-based files using the same corporate logins.

Disk I/O limits are restrictions or controls that limit the amount of disk input/output operations per second (IOPS) that a VM can perform on a storage device or system. CPU oversubscription is a situation where more CPU resources are allocated to VMs than are physically available on the host or server. Disk I/O limits and CPU oversubscription are most likely to cause VDI performance being very slow at the start of the workday, but fine during the rest of the day, as they can create bottlenecks or contention for disk and CPU resources when multiple users log in or launch their VDI sessions at the same time, resulting in increased latency or reduced throughput for VDI operations.
