What is a resource manager?

A resource manager is a software system that is designed to manage and optimize the allocation of computer resources to various applications and programs. These resources can include CPU cycles, memory, disk space, network bandwidth, and more. A resource manager can prioritize resources for different applications based on predefined rules, user priorities, or other criteria. It can also monitor resource usage and adjust allocation as needed to ensure that all applications have the resources they need to function properly. Resource managers can be used in a variety of settings, including enterprise IT environments, cloud computing services, and high-performance computing clusters. They can help organizations optimize their use of resources, improve performance, and reduce costs by minimizing waste and unnecessary use of resources.
