Cloud Computing could be the next big leap in enterprises across all industries. In generic terms, cloud computing involves delivering hosted services over the internet. The concept is similar to an electricity grid where one only pays to the extent of your utilization. A cloud could be public or private. A public cloud sells services to anyone on the internet whereas a private cloud is a proprietary network that supplies services to limited people. These services are divided into three categories--Infrastructure-as-a-Services (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). It is also relevant in today's context as all industries across the globe face recessions at different times due to various reasons, one of the primary ones being fluctuations in the world economy. With the industry being in dire need for resources at minimal cost, it only makes sense to look at cloud sourcing for their internet, software and infrastructure requirements. The paper not only explains and gives a synopsis of cloud computing, but also highlights the advantages of cloud sourcing across different industries. Amazon, Microsoft, Google, IBM, Salesforce are some of the major players in cloud computing. Although cloud computing may be beneficial to enterprises, it is accompanied with its limitations and challenges which still need to be addressed. The main advantage is improved speed and flexibility at lower cost. The paper is well illustrated to give a basic overview of cloud computing.
