Power management of multi-tier virtualized web services

Virtualized web server's performance and power are vital challenges at the present time. A solitary machine consists of many virtualized web servers. The cluster of web servers pooled to form different tier is consigned as multi-tier web servers. The performance of the weighty work loaded virtualized tier may plunge below the permissible limit and also the power consumption will increase. Performance of all virtual machines has to be uplifted simultaneously using intellectual power saving mechanisms. The reprehensible maintenance of the performance and power of one virtual machine may impinge on the others to breach their performance specifications. Here, we propose a power reduction technique using dynamic controller and dynamic modulator to clasp multi-tier web services by modelling the correlations between the virtual machines that run different tiers. Results showing the correlation between virtual machines that run at different tiers give enhanced level in power reduction where virtualized web servers are successively exploited.
