About this book
Cloud Computing: Implementation, Management, and Security provides an understanding of what cloud computing really means, explores how disruptive it may become in the future, and examines its advantages and disadvantages. It gives business executives the knowledge necessary to make informed, educated decisions regarding cloud initiatives.The authors first discuss the evolution of computing from a historical perspective, focusing primarily on advances that led to the development of cloud computing. They then survey some of the critical components that are necessary to make the cloud computing paradigm feasible. They also present various standards based on the use and implementation issues surrounding cloud computing and describe the infrastructure management that is maintained by cloud computing service providers. After addressing significant legal and philosophical issues, the book concludes with a hard look at successful cloud computing vendors.Helping to overcome the lack of understanding currently preventing even faster adoption of cloud computing, this book arms readers with guidance essential to make smart, strategic decisions on cloud initiatives.

Foreword
While there is no arguing about the staying power of the cloud model and the benefits it can bring to any organization or government, mainstream adoption depends on several key variables falling into alignment that will provide users the reliability, desired outcomes, and levels of trust necessary to truly usher in a “cloud revolution.” Until recently, early adopters of cloud computing in the public and private sectors were the catalyst for helping drive technological innovation and increased adoption of cloud-based strategies, moving us closer to this inevitable reality. Today, driven in large part by the financial crisis gripping the global economy, more and more organizations are turning toward cloud computing as a low-cost means of delivering quick-time-to-market solutions for mission-critical operations and services. The benefits of cloud computing are hard to dispute:
- Reduced implementation and maintenance costs
- Increased mobility for a global workforce
- Flexible and scalable infrastructures
- Quick time to market
- IT department transformation (focus on innovation vs. maintenance and implementation)
- “Greening” of the data center
- Increased availability of high-performance applications to small/ medium-sized businesses
Gartner, in a February 2, 2009, press release, posed the question of why, when “the cloud computing market is in a period of excitement, growth and high potential. . . [we] will still require several years and many changes in the market before cloud computing is a mainstream IT effort”?1 In talking with government and industry leaders about this, it became clear that the individual concerns and variables that were negatively impacting business leaders’ thought processes regarding cloud computing (and therefore preventing what could be even more growth in this market) could be boiled down to one addressable need: a lack of understanding. Let’s take this case in point: GTRA research showed that the most common concern about implementing cloud programs was security and privacy, a finding supported by an IDC study of 244 CIOs on cloud computing, in which 75% of respondents listed security as their number-one concern.2 It is true that moving from architectures that were built for on-premises services and secured by firewalls and threat-detection systems to mobile environments with SaaS applications makes previous architectures unsuitable to secure data effectively. In addition, at a March 2009 FTC meeting discussing cloud computing security and related privacy issues, it was agreed that data management services might experience failure similar to the current financial meltdown if further regulation was not implemented. In short, some executives are simply too scared to move forward with cloud initiatives.
However, this concern, while valid, is not insurmountable. Already there are countless examples of successful cloud computing implementations, from small organizations up to large enterprises that have low risk tolerance, such as the U.S. Department of the Navy. The security community is also coming together through various initiatives aimed at education and guidance creation. The National Institute of Standards and Technologies (NIST) is releasing its first guidelines for agencies that want to use cloud computing in the second half of 2009, and groups such as the Jericho forum are bringing security executives together to collaborate and deliver solutions. As with any em...
