Introduction to Enterprise Services and Cloud Resources1
Cloud Computing is the latest revolution in the Information Technology (IT) industry, following the personal computer revolution and the Internet revolution. This new technology not only matters to the IT industry, but also to technology consumers because its services will soon be directly accessible to consumers’ daily appliance-level devices. Cloud Computing is named after the Cloud representation of the Internet commonly depicted on a network diagram. Its concept broadly implies using the Internet to allow people to have access to virtualized resources, whereby users can manage and control their purchased services. This technology, sometimes also associated with Grid Computing, can be seen as a reincarnation of centralized data processing and storage, as paralleled by the mainframe. It is a resource delivery and usage model, meaning it gets resources via the network on-demand and at scale in a multi-tenant environment. The prime revolutionary aspect of Cloud Computing is its ability to deploy location-independent services. Although the model is similar to a large network of computers that is managed by large organizations that provide services to smaller organizations or individual clients, service consumers (SCs) are no longer locked-in with their providers. This revolutionary technology enables users to switch providers easily and quickly due to its open nature. Although from a user’s or application developer’s perspective only the Cloud is referenced, the managing service providers (SPs) who provide software, hardware, Operating Systems (OS), and networking services now face new process and technology challenges that never existed before. The main challenge includes managing various infrastructures across multiple organizations consisting of frameworks that now include self-healing, self-monitoring, and automatic reconfiguring missioncritical applications. In this chapter, the authors intend to draw a foundation for the Cloud service environment from an enterprise perspective to illustrate the business, technical, process, and organizational challenges of this new revolution. This chapter will serve as the foundation for the solution discussions in the following chapters.

1 Introduction to Enterprise Services and Cloud Resources
1.1 Introduction to Enterprises “Enterprise” in the context of this book is defined as an organization or cross-organizational entity performing within a specific business scope and mission. Business operations in an enterprise environment are heavily influenced by dynamic patterns of collaboration and are associated with different levels of accountability. This requires information integration across the management processes, operational processes, and supporting processes that are scattered across many functional areas as different services.
