This is the era of Cloud Computing. A gradual change from centralized to distributed execution is taking place, but not without some practical issues related to process migrations (transparent middleware, efficient and secure data transmissions, \u2026). Extending Amdahl\u2019s law to Cloud Computing will provide a better understanding of the involved factors related to the offloading process such as the time and energy speedups, together with some hints about the future of this era.<\/p>\n<p><a href=\"http:\/\/www.rtc.us.es\/wp-content\/uploads\/2016\/07\/Extending-Amdahls-Law-ForFig1.png\"><img loading=\"lazy\" class=\"size-full wp-image-1315 aligncenter\" src=\"http:\/\/www.rtc.us.es\/wp-content\/uploads\/2016\/07\/Extending-Amdahls-Law-ForFig1.png\" alt=\"Extending Amdahl's Law ForFig1\" width=\"591\" height=\"306\" \/><\/a><\/p>\n<p style=\"text-align: center;\">Figure 1.
