With further development and wide acceptance of cloud computing, lots of companies and colleges decide to take advantage of it in their own data centers, which is known as private clouds. Since private clouds have some unique characteristics and special requirements, it is still a challenging problem to effectively schedule virtual machine requests onto compute nodes, especially with multiple objectives to meet. In this paper, the authors explore couples of characteristics related to workflow scheduling in the scenario of private clouds and propose a hybrid energy-efficient scheduling approach. The experiments show that it can save more time for users, conserve more energy and achieve higher level of load balancing.
