BackgroundOur group has done the analysis of the IT application of Google Incorporation which is a company engaging in goods and services that are internet-related. In 1998, it was founded by Larry Page and Sergey Brin. It is one of the biggest technology company worldwide. Therefore, it has adopted various types of Information Technology applications. This paper focuses on the part of cloud computing.Cloud ComputingCloud computing is a model for enabling ubiquitous, convenient, on-demand networkaccess to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction (Mell & Grance, 2011). It can be divided generally in three types. They are platform as a service (PaaS), software as a service (SaaS) and infrastructure as a service (IaaS) (Armbrust et al., 2010). SaaS is where computer applications are accessed over theInternet rather than being installed on a local computing device or in a local data centre. (ExplainingComputer.com, 2016). PaaS is a software environment used to develop and run applications (ExplainingComputer.com, 2016). IaaS is where a cloud supplier provides online infrastructure on which their customers can store data and develop and run whatever applications they please (ExplainingComputer.com, 2016). Nowadays, there is a trend of the increase in the use of cloud computing. We also have many chances to use cloud computing technology in the real life.
