Further Readings 1.1 Introduction Cloud Computing can be defined as delivering computing power( CPU, RAM, Network Speeds, Storage OS software) a service over a network (usually on the internet) rather than physically having the computing resources at the customer location. Cloud Computing providers offer their services according to different models, sometimes called layers. The 3 standard models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). As Cloud Computing is growing, the role of IT staff is consistently changing. The new roles of IT specialists are those of coordinator and broker. Cloud Computing allows companies to avoid or minimize fixed, IT infrastructure costs. Moreover, third-party clouds enable organizations to focus on their core businesses. Flexibility and scalability are other often-cited benefits of cloud computing. 1.2 Objectives This chapter gives introduction to: Fundamentals of Cloud Computing History Advantages and disadvantages of Cloud Computing Working with Cloud Computing Benefits over Cloud Computing 1.3 History In a world that sees new technological trends bloom and fade on almost a daily basis, one new trend promises more longevity. This trend is called cloud computing, and it will change the way you use your computer and the Internet. Cloud computing portends a major change in how we store information and run applications. Instead of running programs and data on an individual desktop computer, everything is hosted in the “cloud”—a nebulous assemblage of computers and servers accessed via the Internet. Cloud computing lets you access all your applications and documents from anywhere in the world, freeing you from the confines of the desktop and making it easier for group members in different locations to collaborate. Cloud computing has as its antecedents both client/server computing and peer-to-peer distributed computing. It’s all a matter of how centralized storage facilitates collaboration and how multiple computers work together to Self-Instructional Material increase computing power. 1 Client/Server Computing: Centralized Applications and Storage In the antediluvian days of computing (pre-1980 or so), everything operated Cloud Computing Basics on the client/server model.

  • The Server Virtualization Landscape, Circa 2007
    ghaff@ illuminata.com Copyright © 2007 Illuminata, Inc. single user license Gordon R Haff Illuminata, Inc. TM The Server Virtualization Bazaar, Circa 2007 Inspired by both industry hype and legitimate customer excitement, many Research Note companies seem to have taken to using the “virtualization” moniker more as the hip phrase of the moment than as something that’s supposed to convey actual meaning. Think of it as “eCommerce” or “Internet-enabled” for the Noughts. The din is loud. It doesn’t help matters that virtualization, in the broad sense of “remapping physical resources to more useful logical ones,” spans a huge swath of Gordon Haff technologies—including some that are so baked-in that most people don’t even 27 July 2007 think of them as virtualization any longer. Personally licensed to Gordon R Haff of Illuminata, Inc. for your personal education and individual work functions. Providing its contents to external parties, including by quotation, violates our copyright and is expressly forbidden. However, one particular group of approaches is capturing an outsized share of the limelight today. That would, of course, be what’s commonly referred to as “server virtualization.” Although server virtualization is in the minds of many inextricably tied to the name of one company—VMware—there are many companies in this space. Their offerings include not only products that let multiple virtual machines (VMs) coexist on a single physical server, but also related approaches such as operating system (OS) virtualization or containers. In the pages that follow, I offer a guide to today’s server virtualization bazaar— which at first glance can perhaps seem just a dreadfully confusing jumble.

Virtualization is one of the key enablers of the cloud infrastructure. Availability of the virtual machines along with the availability of the hosted software components are the fundamental ingredients for achieving highly available services in the cloud. There are some availability solutions developed by virtualization vendors like VMware HA and VMware FT. At the same time the SAForum specifications and OpenSAF as a compliant implementation offer a standard based open solution for service high availability.

Instead, each OS running on a physical consumption, better management through central server becomes converted to a distinct OS running inside environment control, more availability, reduced project a virtual machine.
