“Cloud Computing. As enterprises seek to consume their IT services in the most cost-effective way, interest is growing in drawing a broad range of services (for example, computational power, storage and business applications) from the "cloud," rather than from on-premises equipment. The levels of hype around cloud computing in the IT industry are deafening, with every vendor expounding its cloud strategy and variations, such as private cloud computing and hybrid approaches, compounding the hype.”
“Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS). The datacenter hardware and software is what we will call a Cloud. When a Cloud is made available in a pay-as-you-go manner to the general public, we call it a Public Cloud; the service being sold is Utility Computing. We use the term Private Cloud to refer to internal datacenters of a business or other organization, not made available to the general public. Thus, Cloud Computing is the sum of SaaS and Utility Computing, but does not include Private Clouds.” (pg. 1)
“Bubble memory is a type of non-volatile computer memory that uses a thin film of a magnetic material to hold small magnetized areas, known as bubbles or domains, each of which stores one bit of data. Bubble memory started out as a promising technology in the 1970s, but failed commercially as hard disk prices fell rapidly in the 1980s.”

The path to secure cloud computing is surely a long one, requiring the participation of a broad set of stakeholders on a global basis.” (page 4)
