How can you limit resource usage of processes on Stallion Server?

• A. By utilizing virtual machines
• B. By using monitoring tools
• C. By using control groups (cgroups)
• D. By increasing server memory

Answer: (C)

Using control groups, or cgroups, is an effective way to limit the resource usage of processes on Stallion Server. Cgroups enable the allocation and management of system resources such as CPU, memory, and I/O bandwidth among different processes or groups of processes. This means you can set limits on how much CPU time a process can use or how much memory it can consume, ensuring that no single process can overwhelm the system resources. This method is particularly advantageous for managing multiple applications running concurrently on the server, ensuring each application functions smoothly without interfering with the others. By establishing these limits, administrators can maintain the overall health and performance of the server, preventing any resource-heavy processes from degrading overall system performance. In contrast, while utilizing virtual machines might provide some degree of resource isolation, it typically involves more overhead and is not as granular or efficient as using cgroups for resource limitation. Monitoring tools provide insights into resource usage but do not actively limit it. Increasing server memory will help handle higher loads but does not directly control or limit existing processes’ usage. Therefore, cgroups stand out as the most effective method for directly managing and limiting the resources utilized by processes.
