For applications with significant disk I/O requirements, deploying directly on bare metal (physical servers) can provide the best performance and meet specific platform requirements. Disk I/O Performance: Bare metal servers offer direct access to hardware resources, ensuring maximum disk I/O performance. Automation: Modern infrastructure automation tools can fully automate the deployment, configuration, and management of bare metal servers. Option C meets the requirements of significant disk I/O performance and full automation. Reference: Cisco DevNet Documentation: Bare Metal Automation
