SMARTDesktop - Microsoft Licensing & Total Cost of Ownership – Part 2

By -


Journey
Last article (part 1) was all about the definition of VDI, types of deployment, the flexibility that SMARTDesktop would bring on to the table thus increasing the benefits.
In this article, we shall take a customer scenario and try to explain the Microsoft Licenses to be procured by the customer.
Assumptions:
  1. Total Number of Users / end points – 200
  2. Customer's ERP runs only on Microsoft Windows Operating System both on server and client side.
  3. Customer has not implemented the Web client for the ERP, thus sticking to desktop client to be installed on every individual endpoint.
  4. Customer wants to reuse his existing PCs but need to change the operating system as Microsoft has ended the extended support and mainstream support for Windows XP and Windows 7 respectively.
  5. Customer has already started using Open Office across the organization.
  6. Customer wants to have better control over the licenses and wants to remove the overhead of maintaining each end-point across the enterprise.
  7. In case of replacing the existing desktops / laptops, customer wishes to have the flexibility in the choice of end-point client devices and also wants to enable the corporate application access over the tablets, mobile devices.
  8. Customer wish to integrate with existing Active Directory Domain for user management & authentication. Domain is installed on Windows Server 2008 R2.
  9. Customer wish to implement the solution with High Availability & Load balanced configuration.
  10. Customer does not have any virtualization platform, is open to implement an Open Source based Hypervisor.

Any CAL, must be of the same or higher edition & version. Just in case customer has license for Windows Server 2003 CALs, the same cannot be reused when the customer wants switch over to either Windows Server 2008 or 2012. 

Sicne the customer is not using any office applications from Microsoft, there is no need to procure any office license. Just in case any customers were to use Microsoft Office in VDI environment (Shared Sessions or VDI), licenses for total number of end devices used to access the office applications must be procured separately. If customer wishes to use Office 365, customer must subscribe to license for total number of users plus 1 Office 2013 standard license to install on VDI environment.

Linux Servers used in the SMARTDesktop deployment are totally free, unless customer wants to use RedHat or SuSE Enterprise Linux that is available only against support subscription. 

We shall come back here again with TCO analysis for the same customer scenario.

Sometime back the an institution promoted by Central Bank in India had conducted workshop on " Road for adoption of Open Sour ce Software in Banks", where we had presented a case study on the extent of Open Source Adaption in one of the Premier Scheduled Commercial Bank Headquartered in South India.  The bank has a staff strength of about 7500, operating about 800 branches across the country. I thought I should present this specific case study here through this article. Probably this will set the standards for adoption of Open Source technology for different critical and non-critical functions. The bank, for core banking system, has been operating the Proprietary Software for long and they continue to upgrade the same for their core operations. However the bank, during the year 2003, for many applications like HR Leave Management, Customer Grievance Portals, IT Support Management, Bills Collections, internal chat, file sharing etc., that are classified as non-critical and

SMARTDesktop - The VDI Solution

Microsoft ending its support for some of its products has actually turned into a money-saver for many organizations.  Many organizations have used this opportunity to move out of the grip of Microsoft and into the world of open source.  New VDI ( SMARTDesktop ) solutions have now stepped in to support such moves. Some time back, Microsoft ended its support for Windows XP along with Internet Explorer V8. Microsoft also ended the mainstream support to Windows 7 on January 13, 2015 and is urging its user base to adopt Windows 8.1.  As current and future versions of Windows and Office demand desktops of higher power and configuration, sustaining loyalty to Microsoft would mean buying new end-point hardware of increased configuration to support latest Microsoft Operating System & applications. Traditional VDI solutions are locked to Microsoft Operating Systems and does not allow users to deliver free & open source applications from a Linux Server. This results in si
