Question

Compare how Windows and Linux resources are managed.

Answer 1

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

When Linux servers under perform—particularly multi-purpose systems running multiple applications for multiple user groups—the root cause is frequently resource monopolization by one or more processes or users.

Control groups (cgroups) are a feature of the Linux kernel that provide mechanisms for partitioning sets of tasks into one or many hierarchical groups, and associating each group with a set of subsystem resource parameters that affect their execution performance. You might use control groups:

• To keep a Web server from using all the memory on a system that’s also running a data base
• To keep a backup system from using too much network I/O bandwidth and crashing the business apps running on the same system
• To allocate system resources among user groups of different priority (the faculty, staff and students of a university, for instance)

There are two types of control group subsystems. Isolation and special controls subsystems include five different controls: CPUset, Namespace, Freezer, Device and Checkpoint and Restart. Resource subsystems are a group of four controls: CPU, Memory, Disk and Network. Before we investigate the functions of each subsystem, it’s important to note that all are implemented in exactly the same manner, by mounting one or more subsystems as virtual file systems.

You can use Windows System Resource Manager to allocate processor and memory resources to applications, users, Remote Desktop Services sessions, and Internet Information Services (IIS) application pools.

With Windows System Resource Manager for the Windows Server® 2012 operating system, you can manage server processor and memory usage with standard or custom resource policies. Managing your resources can help ensure that all the services provided by a single server are available on an equal basis or that your resources will always be available to high-priority applications, services, or users.

Windows System Resource Manager only manages processor resources when the combined processor load is greater than 70 percent. This means that it does not actively limit the resources that can be used by each consumer when processor load is low. When there is contention for processor resources, resource allocation policies help ensure minimum resource availability based on the management profile that you define.
