Presentation Methods for Task Migration in Cloud Computing by Combination of Yu Router and Post-Copy

One of the techniques for increasing flexibility and scalability of cloud data centers is Task Migration. The act of migration is performed for different goals like balancing and load sharing, energy management and reducing response time and improvement of Quality of Service. In this paper, different kinds of migrations like Pre-Copy, Post-Copy, TPM triple migration, and related issues are studied. A new approach is being proposed by the combination of post-copy and Yu. First in proposed approach, sub activities have been sent according to Yu routing from source machine to the destination machine and all tasks in source machine are getting stopped and destination machine will continue those tasks. Results of simulation done by MATLAB software shows that proposed approach leads to overload reduction of server system. Finally, to demonstrate the performance of the proposed approach in terms of transforming time and overload will be assessed and compared with methods of Post-Copy and Yu.
