  • Introduced the compartment isolation technique to achieve the security aware VM consolidation.
  • Different types of simulation setup and the subsequent result confirms that there are no abrupt

changes in power consumption to achieve security aware VM consolidation.

  • The solution presents an added protection measure with the minimal impact on energy efficient

algorithm.

  • This work could be extended to improve the VM reliability as well as security and energy
