It became very familiar due to its various applications and services. This technology plays a vital role in several aspects in all organizations in the world. Moreover, Cloud is used in several areas of information technology everyday by the people. Some of the areas are discussed in this script; they are image processing, security, data placement, resource allocation and data mining. This writing presents the various ideologies used in the significant areas in the Cloud. Keywords: Cloud computing, Image processing, Security, Data placement, Resource allocation. INTRODUCTION Information Technology changes the style of the people every day in the organizations. The increasing use of information technology has brought with it overheads in the implementation and maintenance of in-house computer systems. The amount of time and finances spent in managing it has increased exponentially; each decade since the 1970s has seen the evolution of it into new phenomenon. In the early 1990s, the Internet transformed the way businesses communicate. By the mid- 90s, e-commerce virtualized purchasing for customers and business partners. Today, the cloud computing plays a vital role and undertaking broad changes in the way IT services are designed, delivered, consumed, and managed. The boom in cloud computing over the past few years has led to a situation that is common to many innovations and new technologies: “Cloud computing” was coined for what happens when applications and facilities are moved into the “cloud” World. The cloud computing allows users, wherever they are, to obtain computing capabilities through the Internet from a remote network of servers. Cloud computing is not something that suddenly appeared overnight; in some form it may trace back to a time when computer systems remotely time-shared computing resources and applications. More currently though, cloud computing refers to the many different types of services and applications
