One area of Change with Implementation

PlanMobile Cloud Computing Services

Cloud Computing Service providers deliver common business

applications online which are accessed through web browsers.

Why Mobile Cloud?

With the advent of 3G and LTE technology, customers using

data services are going to increase manifold.

These days high end users use smart phones having

configurations and processor speeds in GHz.

But it is virtually impossible to store huge quantities of

data/install high utility softwares on phones having memoryupto 32Gb

Cloud Services for Internet are growing daily at unprecedented

growth due to increase in data transfer rates across the globe.

Implementation Plan

Cloud Computing Service Agreements can be done with VAS

third party vendors.

Cloud service providers are increasing day by day in market so a

strong company can take advantage of its existing technology

and experience in the domain.

Mobile data backup can easily be done on any third party serverby using conventional HTTP protocol on mobile browser or any

FTP session created temporarily.

SaaS functionality can also be provided with the help of third

party vendor

Idea can hence get a early mover advantage in this multi billion

market.
