Cloud Computing offers such smartphones that have rich Internet media experience and require less processing, less power.

In term of Mobile Cloud Computing, processing is done in the cloud, data is stored in the cloud. And the mobile devices serve as a media for display.

Today smartphones are employed with rich cloud services by integrating applications that consume web services. These web services are deployed in the cloud.

There are several Smartphone operating systems available such as Google's Android, Apple's iOS, RIM BlackBerry, Symbian, and Windows Mobile Phone. Each of these platforms supports third-party applications that are deployed in the cloud.

Mobile Architecture

Mobile Cloud Computing (MCC) includes four types of cloud resources:

1.       Distant mobile cloud

2.       Distant immobile cloud

3.       Proximate mobile computing entities

4.       Proximate immobile computing entries

5.       Hybrid

Challenges and Issues

Emergency efficient transmission

There should be a frequent transmission of information between cloud and the mobile devices.

Architectural issues

Mobile cloud computing is required to make architectural neutral because of a heterogeneous environment.

Live VM Migration

It is challenging to migrate an application, which is resource-intensive to cloud and to execute it via Virtual Machine.

Mobile communication congestion

Due to continuous increasing demand for mobile cloud services, the workload to enable smooth communication between cloud and mobile devices has been increased.

Security and privacy

This is one of the major issues because mobile users share their personal information over the cloud.
