Cloud Computing Iaas Infrastructure As A Service Specialist Level Complete Certification Kit - Infrastructure As A Service Study Guide Book And Online

RRP $492.99

Cloud computing has dramatically changed how business applications are built and run. At its core, cloud computing eliminates the costs and complexity of evaluating, buying, configuring, and managing all the hardware and software needed for enterprise applications. Instead, these applications are delivered as a service over the Internet. Whenever the term infrastructure is used, the resulting images will involve some set of physical devices. In IT, the infrastructure comprises all the physical computing devices required to enable an enterprise or individual to produce some result supporting the goals of the business. The role of the infrastructure is to make the achievement of the result easier and to increase its value to the business. Infrastructure as a Service is another method for managing and delivering the framework required to operate the business. At its core, Infrastructure as a Service (IaaS) must be discussed on two fronts: its construction and its presentation. The construction of an IaaS comprises the physical hardware and software used to provide the foundation for supporting the business. In a traditional IT solution, this foundation included servers, routers and bridges, and, in many cases, the technologies and solutions used to create the infrastructure were highly standardized. For IaaS, the physical infrastructure still remains, but how it is presented to the customer is radically different. The presentation of IaaS is an abstraction of the physical infrastructure. One might think of this abstraction as a software-based representation of the physical infrastructure and that perspective would not be without merit. For a business, an IaaS has a radical impact on how IT is delivered and managed because it is possible to purchase the right to use the abstraction of an infrastructure without purchasing and managing the physical infrastructure. New to IaaS? Welcome! If you're just starting to explore the concept of IaaS, this is the place to find out what IaaS can do for you, understand different types of IaaS solutions, and learn more about developing IaaS. The Infrastructure as a Service Specialist level certification kit explores the concepts of Infrastructure as a Service (IaaS) and where they apply in the current technological world. Using this book and the accompanying elearning materials, you will gain an understanding of the goals, objectives, benefits and challenges of the different types of IaaS and how they support the relevant IT Service Management processes. This certification kit will prepare you for the Infrastructure as a Service (IaaS) Specialist Level Exam. The pre-requisite for this program is the completion of the Cloud Computing Foundation Program. This Kit contains the book and online course access that provides everything you need to prepare for the IaaS Specialist Certification Exam, including in-depth coverage of all exam objectives, scenarios to easily demonstrate the processes in action, and practice exam questions for that last minute test preparation.

Nonlinear Diffusion Equations And Their Equilibrium States: 3

RRP $117.95

Nonlinear diffusion equations have held a prominent place in the theory of partial differential equations, both for the challenging and deep math­ ematical questions posed by such equations and the important role they play in many areas of science and technology. Examples of current inter­ est are biological and chemical pattern formation, semiconductor design, environmental problems such as solute transport in groundwater flow, phase transitions and combustion theory. Central to the theory is the equation Ut = ~cp(U) + f(u). Here ~ denotes the n-dimensional Laplacian, cp and f are given functions and the solution is defined on some domain n x [0, T] in space-time. FUn­ damental questions concern the existence, uniqueness and regularity of so­ lutions, the existence of interfaces or free boundaries, the question as to whether or not the solution can be continued for all time, the asymptotic behavior, both in time and space, and the development of singularities, for instance when the solution ceases to exist after finite time, either through extinction or through blow up.
