Learning Objectives Know what virtualization programming is and its effect on distributed computing Be ready to list the advantages to a firm from utilizing virtualization Know the choices chiefs have while deciding how to fulfill the product needs of their organizations Know the components that must be considered when making the make, purchase, or lease choice

Slide 11

Introduction Software is the two-hundred-billion-dollar-per-year juggernaut Once a fruitful programming item has been composed, the financial aspects for a classification driving offering are among the best you'll discover in any industry Unlike physical items collected from crude materials, the minimal cost to deliver an extra duplicate of a product item is adequately zero This quality prompts to organizations that can spout money

Slide 12

Introduction Network impacts and exchanging expense can offer a main programming firm a level of client inclination and secure. As a rule makes victor take-all business sectors However, the principal show fueling the business is under attack from Open source programming (OSS) offerings Open source programming offerings: Software that is free and where anybody can take a gander at and possibly adjust the code

Slide 13

Introduction Questions confronting enormous programming firms How would we be able to rival free? How might we profit and fuel development on free? Distributed computing is making it more regular for a firm to move programming out of its own IS shop so it is keep running on another person's equipment Cloud figuring : Replacing processing assets (either an association's or individual's equipment or programming) with administrations gave over the Internet Software as an administration (SaaS) : A type of distributed computing where a firm subscribes to an outsider programming and gets an administration that is conveyed on the web

Slide 14

Introduction Hardware mists can give firms a chance to take their product and run it on another person's equipment Virtualization : An innovation that can make a solitary PC carry on like many separate PCs The capacity merges registering assets. It likewise makes extra funds and efficiencies Smaller firms have admittance to the sorts of refined processing power than just goliaths had entry to in the past Startups can scale rapidly and get up and running with less venture capital Existing firms can use these advancements to lessen costs

Slide 15

Open Source Open source programming (OSS) is depicted as free While most OSS can be downloaded for nothing over the Internet, it's additionally "free" as in freed The source code for OSS items is straightforwardly shared Anyone can take a gander at the source code, transform it, and even redistribute it - gave the altered programming keeps on staying open and free

Slide 16

Open Source Open source openness distinct difference an unmistakable difference to the act of customary programming firms: Who regard their licensed innovation as firmly monitored insider facts Who never give the source code to their business items Some organizations consider OSS to be a risk undermining their monetary model Some other huge name innovation organizations are currently unequivocally behind the open source development

Slide 17

Open Source Linux : An open source programming working framework Linux powers everything from phones to stock trades, set top boxes to supercomputers Found on 30 percent of the servers in corporate America

Slide 18

Turn on the LAMP—It's Free! Light : An acronym remaining for L inux, the A pache Web server programming, the M ySQL database, and any of a few programming dialects that begin with P (Example: Perl, Python, or PHP) LAMP programming powers a significant number of the destinations you visit every day, from Facebook to YouTube

Slide 19

Why Open Source? Reasons why firms pick open source items over business options: Cost Reliability Security Scalability Agility and time to advertise

Slide 20

Examples of Open Source Software Firefox OpenOffice Gimp Alfresco Marketcetera Zimbra MySQL, Ingres, and EnterpriseDB SugarCRM Asterix Free BSD and Sun's OpenSolaris

Slide 21

Why Give it Away? The Business of Open Source Open source is a sixty-billion-dollar industry, yet it disproportionaty affects the trillion-dollar IT showcase: By bringing down the cost of registering, open source endeavors make all the more figuring alternatives available to littler firms More dependable, secure processing brings down expenses for all clients OSS occupies reserves that organizations would somehow or another spend on settled costs so that these assets can be spent on development or other more aggressive activities

Slide 22

Why Give it Away? The Business of Open Source Commercial enthusiasm for OSS has started a procurement orgy Red Hat purchased open source application server firm, JBoss, for three hundred fifty million dollars Novell gobbled up SUSE Linux for two hundred ten million dollars Sun plunked down more than one billion dollars for MySOL, an open source database supplier With Oracle's offered for Sun, one of the world's biggest business programming firms, they focused in on one of the most profound arrangement of open source items

Slide 23

Why Give it Away? The Business of Open Source Vendors profit on OSS by offering support and counseling administrations The business' advancement (guidelines rivalry) In the pre-Linux days, about each significant equipment maker made its own particular inconsistent form of the Unix working framework These broke, incongruent markets were small to the point that they experienced issues drawing in outsider sellers to compose application programming Now all real equipment firms run Linux There's an expansive bound together market that pulls in programming designers, who may some way or another compose for Windows

Slide 24

Why Give it Away? The Business of Open Source To keep benchmarks brought together, a few Linux-supporting equipment and programming firms back the Linux Foundation Hardware firms locate their specialized ability can be conveyed in other esteem included administrations like: Developing business programming additional items Offering counseling administrations Enhancing equipment offerings

Slide 25

Why Give it Away? The Business of Open Source Linux has been fruitful on cell phones and purchaser hardware, notwithstanding top of the line server class or more PCs It has not been as effective on the desktop The little client base for desktop Linux makes the stage less alluring for desktop programming designers In industrialized countries, the additional many-sided quality and constrained desktop application accessibility of desktop Linux, isn't justified regardless of the one to two hundred dollars spared by surrendering Windows
