This chapter covers the main contents like the current trend, challenges and future practices of cloud
computing. By the increasing usage of handheld devices is directly proportional to its power consumption
which leads to many other factors such as memory management and less computational power. As
by the time internet and technology is increasing every person would prefer to do his work by using
fewer resources. Cloud computing meet their needs as they required because everything is on cloud
distributed and virtualized. According to some research base mobile applications are estimated to rise
88% per annum from 2009 to 2014 (J. G. Ruay-Shiung Chang et al. 2013).
MCC has made our life easier in an effective way. Handheld devices along with internet connections
made life more comfortable. With this technology we can move our more intensive tasks on cloud. To
comprehend the main challenges in Mobile Cloud Computing one should get the domain knowledge
and deep understandings of cloud computing
