Mission assurance for critical cloud applications is of growing importance to governments and military organizations, yet mission-critical cloud computing may face the challenge of needing to use hybrid (public, private, and/or heterogeneous) clouds and require the realization of “end-to-end” and “cross-layered” security, dependability, and timeliness. In this book, we consider cloud applications in which assigned tasks or duties are performed in accordance with an intended purpose or plan in order to accomplish an assured mission.

1.1 Introduction

Rapid technological advancements in global networking, commercial off-the-shelf technology, security, agility, scalability, reliability, and mobility created a window of opportunity in 2009 for reducing the costs of computation and led to the development of what is now known as cloud computing [1–3]. Later, in 2010, the Obama Administration [4] announced an

“extensive adoption of cloud computing in the federal government to improve information technology (IT) efficiency, reduce costs, and provide a standard platform for delivering government services. In a cloud computing environment, IT resources—services, applications, storage devices and servers, for example—are pooled and managed centrally. These resources can be provisioned and made available on demand via the Internet. The cloud model strengthens the resiliency ...
