Cloud computing is available through various deployment models (public, private, hybrid) and service layers (IaaS, PaaS, SaaS), providing users with remote, on-demand access to computing resources and data storage over the Internet. According to a Dell report, companies that invest in big data,...
Figure 1.5 provides a useful abstraction of cloud computing by dividing it into four layers: application software, development platforms, resource sharing, and infrastructure. The infrastructure layer includes the physical resources in a data center. The resource-sharing layer uses a combination of hardw...
Cloud computing has data leakage from all parties, security protection of private data, and existing solutions do not provide a trade-off between security and overhead. With distributed data communication due to data barriers, information interaction security and data computation security have become ch...
With the advent of cloud computing, it becomes critical for datacenter designers to address the cloud's current and evolving needs. In this paradigm, datacenters physically host all the cloud services that are delivered to users. In turn, the cloud services are abstracted from the underlying phys...

(e.g., two-tier, three-tier, N-tier client–server computing). Considering the potential complexity of business logic in enterprise applications (e.g., asynchronous messaging services, e-mail services, etc.) different layers can also be assumed constructing thus N-layer, N-tier client–server...
Role of Cloud Infrastructure in Cloud Computing Cloud computing refers to renting versus buying compute resources, storage, or other services. It’s an incredibly broad category, applied to nearly anything accessed over the web—for example, photos stored in a backup service, an enterprise CRM or...
systems can result in significant monetary losses to all parties concerned. The very nature of cloud computing systems is that they have a layered architecture. Thus, a fault in one layer of the cloud resources can trigger a failure in other layers above, or hide access to the layers below....
Figure 1.4: The enabling technologies in cloud computing. The emergence of high-speed and ubiquitous networking technologies has greatly contributed to cloud computing as a viable paradigm. Modern networks make it possible for computers to communicate in a fast and reliable manner, which is important...
