      Answer :

      85,000 desktops. La Gendarmerie National, part of the French police force, faced growing IT infrastructure costs and decided to review its existing Microsoft-based environment. After switching from Microsoft Office to OpenOffice.org and from Internet Explorer to Firefox, the police force decided to upgrade 85,000 desktop PCs to Ubuntu, removing its reliance on the Microsoft operating system almost completely. As well as simplifying maintenance and improving ease of use, Ubuntu is saving the police force €2 million a year in licence fees alone. By repurposing 4,500 machines to act as local servers, it has also dramatically reduced its hardware expenditure. The police force’s IT team tested a number of operating systems but found Ubuntu to be the best fit for the organisation.

    9. Question 9. How Can I Create Launchers On My Desktop?

      Answer :

      The old GUI dialog is still available if you still want to use this:

      Using ALT+F2 type gnome-desktop-item-edit –create-new ~/Desktop

      This will launch the old GUI Dialog and create a launcher on your Desktop:

      Take the image from   http://askubuntu.com/questions/64222/how-can-i-create-launchers-on-my-desktop.

      Gnome-desktop-item-edit is installed automatically if you have installed gnome-shell/gnome-fallback. It is also installed automatically if you have previously installed gnome-tweak-tool.

      Alternatively, you can install the old gnome-panel without much of the bulk:

      Sudo apt-get install –no-install-recommends gnome-panel.

    10. Question 10. How Can I Run Unity In A Virtual Machine?

      Answer :

      Install the virtual box and In Virtual Box >= 4.0 Unity is supported and runs nice when Guest Additions are installed.

    11. Question 11. How Do We Do Compliance For Ubuntu?

      Answer :

      As any IT manager knows, compliance is about more than reporting. It starts with the implementation of compliance policies and processes.

      The latest version of Landscape, Canonicals’ systems management tool, introduces extensive access-control extensions, enabling you to implement the access policies you need.

      Roles such as ‘Auditor’ (with read access to everything but write access to nothing) or ‘Security Analyst’ (with authentication to execute scripts but not modify them or create new ones) can be defined, right up to the restriction-free ’Full Administrator’ level. Fine-grained control over these credentials is provided, with a default configuration included to ensure that these features can be used without customization. Meanwhile, CIOs will appreciate the ability to define independent security administrator roles when needed.

    12. Question 12. What’s Canonicals’ Role In Open Stack?

      Answer :

      Ubuntu is the reference operating system for Open Stack, the world’s number one open source cloud infrastructure platform.

      The relationship between Ubuntu and Open Stack is a deep one. The release schedules of the two projects are synchronized, ensuring that Open Stack updates and releases are immediately available on widely deployed releases of Ubuntu. But most important is Ubuntu’s status as the reference OS. This means Ubuntu is the preferred base operating system, the one that most developers of Open Stack use every day. No other operating system is as therefore as tightly integrated with Open Stack – or as stringent tested with the cloud software. In short, if you want to run Open Stack (and if you’re interested in open cloud infrastructure, you definitely should be) then the best advice is to do so on Ubuntu.

    13. Question 13. Why Is Ubuntu The Most Popular Operating System For Cloud?

      Answer :

      Large enterprises such as HP, Microsoft, Rackspace, IBM and Dream Host provide Ubuntu images in their public cloud infrastructure, or run it for their own private and public clouds.

      Ubuntu is the number one operating system on Amazon Web Services and has been closely involved with Open Stack since the very beginning of the project. We can therefore provide engineering, consultancy and support expertise to help with any cloud project, whether you want to run your services on a major public cloud (Open Stack-based or otherwise) or build private cloud infrastructure on your own hardware.

    14. Question 14. Can Ubuntu Be Integrated With Microsoft Infrastructure?

      Answer :

      Yes it can. You can do the work yourself, or you can work with Canonical consultants. Another solution would be to use a third-party technology designed to do just this: you can either migrate your MS servers to Ubuntu-based products such as Zentyal Enterprise Edition or connect your Ubuntu environment to your legacy Microsoft infrastructure using products like Centrify.

    15. Question 15. What Does Ubuntu Mean?

      Answer :

      Ubuntu is an ancient African word meaning ‘humanity to others’. It can also be interpreted as ‘I am what I am because of who we all are’. The Ubuntu operating system brings the spirit of Ubuntu to the world of computing. And one last extra question for the road…
