It can be used in multiple scenarios. To get more details about it, refer to the Book “Virtualization Guide” and in particular, to the following sections: Book “Virtualization Guide”, Chapter 1 “Virtualization Technology”, Section 1.2 “Virtualization Capabilities” Book “Virtualization Guide”, Chapter 1 “Virtualization Technology”, Section 1.3 “Virtualization Benefits” This best practice guide will provide advice for making the right choice in your environment. It will recommend or discourage the usage of options depending on your workload. Fixing conguration issues and performing tuning tasks will increase the performance of VM Guest's near to bare metal. 2 Before You Apply Modifications 2.1 Back Up First Changing the conguration of the VM Guest or the VM Host Server can lead to data loss or an unstable state. It is really important that you do backups of les, data, images, etc. before making any changes. Without backups you cannot restore the original state after a data loss or a misconguration. Do not perform tests or experiments on production systems. -
Ubuntu Server Guide Basic Installation Preparing to Install
Ubuntu Server Guide Welcome to the Ubuntu Server Guide! This site includes information on using Ubuntu Server for the latest LTS release, Ubuntu 20.04 LTS (Focal Fossa). For an offline version as well as versions for previous releases see below. Improving the Documentation If you find any errors or have suggestions for improvements to pages, please use the link at thebottomof each topic titled: “Help improve this document in the forum.” This link will take you to the Server Discourse forum for the specific page you are viewing. There you can share your comments or let us know aboutbugs with any page. PDFs and Previous Releases Below are links to the previous Ubuntu Server release server guides as well as an offline copy of the current version of this site: Ubuntu 20.04 LTS (Focal Fossa): PDF Ubuntu 18.04 LTS (Bionic Beaver): Web and PDF Ubuntu 16.04 LTS (Xenial Xerus): Web and PDF Support There are a couple of different ways that the Ubuntu Server edition is supported: commercial support and community support. The main commercial support (and development funding) is available from Canonical, Ltd. They supply reasonably- priced support contracts on a per desktop or per-server basis. For more information see the Ubuntu Advantage page. Community support is also provided by dedicated individuals and companies that wish to make Ubuntu the best distribution possible. Support is provided through multiple mailing lists, IRC channels, forums, blogs, wikis, etc. The large amount of information available can be overwhelming, but a good search engine query can usually provide an answer to your questions. -

Open Source Software: Risks and Rewards V2.0, 03 August 2005
Open Source Software: Risks and Rewards v2.0, 03 August 2005 Author(s)Gary Hein Conclusion Open source software (OSS) brings new opportunities and risks to information technology (IT) vendors and customers. Software commoditization is being profoundly affected from the infrastructure layer and moving up to the application layer. As a result, OSS is changing the strategies and business models of hardware and software vendors and system integrators. Customers should understand the risks and rewards of OSS, and should formulate strategies that bring OSS benefits to their IT departments while mitigating the business and legal risks. Synopsis Open source software (OSS) is more than just free software. It’s a development process, a distribution model, and a set of new software licenses. And, as characterized by OSS proponents, it’s a movement. OSS projects, such as Linux and Apache HTTP server, are commoditizing enterprise and Internet infrastructure, and thus pose threats for some vendors while creating new market opportunities for others. OSS brings more to information technology (IT) than just free software. It grants freedom from vendor lock-in and application churn, freedom to inspect, modify, and improve source code, and the freedom to influence or contribute to projects key to a company’s survival. But these freedoms come at a price. Although OSS is free, it isn’t always less expensive to implement due to migration, support, training, and maintenance costs. OSS projects add new twists to business risks such as vendor viability and stability, and legal issues remain uncertain as many popular licenses have yet to be tested in a court of law. -
