Study of cloudlet deployed in various environment

Cloud computing is a newly emerging technology. Cloud computing is widely in use because it provides opportunity to dynamically scale the computing resources for applications. Also the resources are efficiently shared among customers using virtualization technology. Over the past two decades, the world economy has rapidly moved from manufacturing to more service-oriented. Since cloud computing environment has large setup and cost associated with it, testing applications and resource allocation policies are highly challenging. Also in today’s generation, mobile devices are widely used like mobile phones, PDA, laptops, etc., which provides public the flexibility to access the cloud while on the move. So, it is difficult to manage the large amount of data on cloud server and allocate the resources efficiently to mobile users or mobile devices [3], [11]. Thus, a new architectural element called CLOUDLET which comes from the convergence of mobile computing technology and cloud computing technology came into existence [3]. It represents the middle tier of a 3-tier hierarchy: mobile device --- cloudlet --- cloud. A cloudlet can be viewed as a "data centre in a box" whose goal is to "bring the cloud closer".
