The least costing server is the application server because it has the lowest used space and allocated space. The file server should have storage increased due to over 70% utilization because it has the highest used space and allocated space. To calculate the cost of each server, we can use the following formula:

Cost = ($1.50 x Used space) + ($0.75 x Allocated space)

Using this formula, we can find the cost of each server as follows:

• Application server: Cost = ($1.50 x 186 GB) + ($0.75 x 250 GB) = $279 + $187.50 = $466.50
• Mail server: Cost = ($1.50 x 250 GB) + ($0.75 x 300 GB) = $375 + $225 = $600
• File server: Cost = ($1.50 x 450 GB) + ($0.75 x 500 GB) = $675 + $375 = $1050

The application server has the lowest cost of $466.50, while the file server has the highest cost of $1050. To find the utilization percentage of each server, we can use the following formula:

Utilization = (Used space / Allocated space) x 100%

Using this formula, we can find the utilization percentage of each server as follows:

• Application server: Utilization = (186 GB / 250 GB) x 100% = 74.4%
• Mail server: Utilization = (250 GB / 300 GB) x 100% = 83.3%
• File server: Utilization = (450 GB / 500 GB) x 100% = 90%

The file server has the highest utilization percentage of 90%, which means that it is running out of storage space and may affect its performance and availability. The application server has the lowest utilization percentage of 74.4%, which means that it has some unused storage space and may be overprovisioned. Therefore, the file server should have storage increased to reduce its utilization and improve its efficiency, while the application server is costing the firm the least and does not need any changes in its storage allocation. References: CompTIA Cloud Essentials+ CLO-002 Study Guide, Chapter 3: Cloud Business Principles, Section 3.4: Cloud Billing and Cost Management, Page 87 and [Cloud Storage Utilization and Optimization | CloudHealth by VMware]

The best solution for this scenario is Virtual Desktop Infrastructure (VDI). VDI is a cloud service model that provides users with virtual desktops that run on a centralized server. Users can access their virtual desktops remotely from any device, such as a laptop, tablet, or smartphone, using a thin client or a web browser. VDI enables users to access business applications without installing them on their own devices, which ensures that these applications are only installed on company-controlled equipment. VDI also allows users to modify their personal working environments, such as desktop settings, wallpapers, or preferences, which are saved on the server and persist across sessions. VDI can offer benefits such as improved security, reduced hardware costs, centralized management, and enhanced user experience. The other options are not the best solutions for this scenario. Single Sign-On (SSO) is a cloud service that enables users to log in to multiple applications or systems with one set of credentials, which simplifies authentication and improves security. However, SSO does not provide users with remote access to business applications or personal working environments. Secure Shell (SSH) is a network protocol that allows secure remote access to a server or a device using encryption and authentication. SSH can be used to execute commands, transfer files, or tunnel network traffic. However, SSH does not provide users with virtual desktops or business applications. Virtual Private Network (VPN) is a network technology that creates a secure connection between a remote device and a private network over a public network, such as the Internet. VPN can be used to access network resources, such as files, printers, or applications, that are not available otherwise. However, VPN does not provide users with virtual desktops or personal working environments. References: CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002), Chapter 2: Cloud Concepts, Section 2.3: Cloud Service Models, p. 64-65

Infrastructure as code (IaC) is a DevOps practice that uses code to define and deploy infrastructure, such as networks, virtual machines, load balancers, and connection topologies1. IaC ensures consistency, repeatability, and scalability of the infrastructure, as well as enables automation and orchestration of the provisioning process2. IaC is different from infrastructure templates, which are predefined configurations that can be reused for multiple deployments3. Infrastructure orchestration is the process of coordinating multiple automation tasks to achieve a desired state of the infrastructure4. Infrastructure automation is the broader term for any technique that uses technology to perform infrastructure tasks without human intervention5.
