Abstract—Cloud computing is a rising technology which enables convenient, on-demand network access to a shared pool of configurable computing resources. Mobile cloud computing is the availability of cloud computing services in a mobile ecosystem. Mobile cloud computing shares with cloud computing the notion that services is provided by a cloud and accessed through mobile platforms. The paper aims to describe an online mobile cloud based compiler which helps to reduce the problems of portability and storage space and resource constraints by making use of the concept of mobile cloud computing. The ability to use compiler application on mobile devices allows a programmer to get easy access of the code and provides most convenient tool to compile the code and remove the errors. Moreover, a mobile cloud based compiler can be used remotely throughout any network connection (WI-FI/ GPRS) on any Smartphone. Thus, avoiding installation of compilers on computers and reducing the dependency on computers to write and execute programs.
