Description: # Terracotta: A Framework for Dynamic Consolidation of Resources in Openstack Clouds
        
        
        Terracotta is an extension to OpenStack implementing dynamic consolidation
        of resources, e.g. Virtual Machines (VMs) using live migration.
        
        Currently, the major objective is dynamic VM consolidation to improve the utilization
        of physical resources and reduce energy consumption by re-allocating resources using
        live migration according to their real-time resource demand and switching idle hosts to
        the sleep mode.
        
        For example, assume that two VMs are placed on two different hosts, but the
        combined resource capacity required by the VMs to serve the current load can be
        provided by just one of the hosts. Then, one of the VMs can be migrated to the
        host serving the other VM, and the idle host can be switched to a low power mode
        to save energy. When the resource demand of either of the VMs increases, they
        get deconsolidated to avoid performance degradation. This process is dynamically
        managed by Terracotta.
        
        In general, the problem of dynamic VM consolidation can be split into 4
        sub-problems:
        
        - Deciding when a host is considered to be underloaded, so that all the VMs
          should be migrated from it, and the host should be switched to a low power
          mode, such as the sleep mode.
        - Deciding when a host is considered to be overloaded, so that some VMs should
          be migrated from the host to other hosts to avoid performance degradation.
        - Selecting VMs to migrate from an overloaded host out of the full set of the
          VMs currently served by the host.
        - Placing VMs selected for migration to other active or re-activated hosts.
        
        The aim of the Terracotta project is to provide an extensible framework for
        dynamic consolidation of resources based on the OpenStack platform. The framework
        provides an infrastructure enabling the interaction of components implementing
        the 4 decision-making algorithms listed above. The framework allows
        configuration-driven switching of different implementations of the
        decision-making algorithms.
        
        
        ## More details
        
        The Terracotta project idea originally comes from the
        [paper](http://beloglazov.info/papers/2014-ccpe-openstack-neat.pdf) describing
        the architecture and implementation of OpenStack Neat and Chapter 6 of Anton
        Beloglazov's PhD thesis: http://beloglazov.info/thesis.pdf. After discussion with
        the author, we are authorized to use Neat as the Terracotta code base at the very
        early stage. However, a lot of work need to be done according to OpenStack project's
        requirement.
