Scaling and efficiency

Mesos aims to provide a highly scalable and efficient mechanism to enable various frameworks to share cluster resources effectively. Distributed applications are varied, can have different priorities in different contexts, and are continuously evolving, a fact that led Mesos' design philosophy towards providing for customizable resource allocation policies that users can define and set as per their requirements.

Resource allocation

The Mesos resource allocation module contains the policy that the Mesos master uses to determine the type and quantity of resource offers that need to be made to each framework. Organizations can customize it to implement their own allocation policy, for example, fair sharing, priority, and so on, which allow for fine-grained resource sharing. Custom allocation modules can be developed to address specific needs.

The resource allocation module is responsible for making sure that the resources are shared in a fair manner among competing frameworks...
