What is the main purpose of monitoring CPU utilization in a cloud environment?

Monitoring CPU utilization in a cloud environment primarily serves to improve overall system performance and ensure efficient resource allocation. By keeping an eye on CPU usage, administrators can identify performance bottlenecks and optimize the application and service configurations, thereby enhancing user experience. When CPU resources are over-utilized, users might face delays or slow responses from applications, adversely affecting productivity and satisfaction.

While the other options touch on important aspects of cloud management, they don't directly relate to the central focus of CPU monitoring. For instance, optimizing network speed is primarily associated with bandwidth management and network latency rather than CPU performance. Detecting unauthorized crypto activities relates more to security and monitoring unconventional computing patterns, rather than performance optimization. Lastly, while CPU resources do influence database operations, they are just one aspect of a multifaceted database management system that also includes storage and I/O considerations. Therefore, the main purpose of monitoring CPU utilization is closely linked to enhancing the performance and responsiveness of applications, ultimately leading to a better user experience.
