Three-Tier Cloud Architecture to Enhance Resource Efficiency for Cloud-Based Applications

Recent years have witnessed a new era of computing where smart mobile devices with sophisticated operating systems are seamlessly being used for performing day to day activities. Compared with their tethered counterparts, these devices provide a computing tool to the user to seamlessly continue the work irrespective of movement [1]. Now the mobile devices are no longer considered as just the voice communication devices, instead these devices have changed the computing world. Recent years have also witnessed a subsequent growth in applications targeted to run on mobile devices [2]. Despite the advancements in hardware technology of mobile devices, these devices are still not able to fulfill all the computational requirements of the users [3], [4]. Some of the compute intensive applications like natural language processing, real time speech recognition, augmented reality etc. still prove to be too expensive for mobile devices in terms of computational resources and battery life [2]. Various limitations that motivated the introduction of Mobile Cloud Computing (MCC) services for mobile devices are: limited processing capabilities, limited storage, limited battery, and limited visualization capabilities
