Skype for Business - On-Premise vs Online / Hybrid Setup RRS feed

  • Question

  • Dear All,

    We are a campus that is part of a transnational university but with entirely separate infrastructure from the rest of the University.  

    We are currently in the process of exploring the option of going with Skype for Business and wondering which option to go with, On-Premise or Online or Hybrid.

    Current Infrastructure:

    • Fully On-Premise including Exchange / AD / other Applications.
    • Exchange is being migrated from 2007 to 2013/2016 On-Premise for staff mailboxes only.
    • Hardware ready for Skype for Business to be hosted On-Premise.
    • Email Integration with Office 365 and almost 1900 student's mailboxes migrated to Exchange Online, staff and faculty will be migrated later based on the decision (On-Premise vs Online)

    On the other hand, as a member of a transnational University, we are under another process of starting a project (Unified Infrastructure) for all our sites. Instead of individual AD / Exchange / Identical Applications across all sites, instead it will be a Single AD forest / Single Exchange (On-Premise) or Online, Single Enterprise Applications / CRM with multiple instances that suite each site. This will be the ultimate goal.

    We are based in EMEA (Gulf) and as far as my understanding there are some limitations when it comes to Cloud PBX functionality and as our goal is to rip out our legacy PBX system, provided all the current features and functionality can be carried over to Skype for Business.

    Its a dilemma of where to start and which option to choose and what are the limitations of each option....

    Everything Online... What are the limitations...?

    • Migrate all Mailboxes to Office 365 with E5 plan for staff...
    • Subscribe with Skype for Business Online (keep in mind that Microsoft PSTN calling service is not available in the Gulf but Cloud PBX is)

    Everything On-Premise... What are the limitations going forward and starting with having single AD forest / and migrate from On-Premise to Online at a future date.

    • Migrate to Exchange 2013/2016
    • Install On-Premise Skype for Business

    Highly appreciate your recommendation.

    Regards,

    Hussain

  • Hi,

    For the issue that the way to move SFB Server to another forest, there is no way to achieve. Only to deploy a new SFB environment and then export and import user data to the new SFB Server environment.

    Best Regards

  • Hi,

    You can refer to following article to know the comparison between online and on-premise. 

    http://www.rtcpedia.com/Blogs/Action?blogId=10049&blogURL=MicrosoftSkypeforBusinessOnlineVsOnPremise

    You can refer following article to know about the features not supported if Skype For Business (SFB) online integrated with Microsoft Exchange on-premise

    http://www.rtcpedia.com/Blogs/Action?blogId=24&blogURL=SFBIntegratedMicrosoftExchange

    All limitations and benefits of online service would be applicable whenever you plan to migrate on-premise service to online!

  • Thank you very much Ram for your reply, that's answering the bits about
    on-Premise vs Online,  I think there is another comparison list which is
    uncovered in here... Exchange Online with Skype For Business on-Premise or Skype
    Online and Exchange Online/On-Premise.

    This brings up the conversation of Skype for Business as an
    mid-urgent requirements in conjunction with Single Global Tenants either
    on-Premise or Online..  which is better build the new AD forests architecture,
    move current services and later on think of Skype for Business deployment vs Go
    ahead with Skype for Business and later on migrate the Skype including other
    services to the new AD Forests.. ?
    Will Skype be easy enough to be moved to
    another domain AD forests without reinventing the wheel.. ?

    Regards

  • Hi, these are the limits:

    Exchange Online: https://technet.microsoft.com/en-us/library/exchange-online-limits.aspx?f=255&MSPPError=-2147217396

    Skype for business online: https://technet.microsoft.com/nb-no/library/skype-for-business-online-limits.aspx

    In short, go exchange online for everyone, then you avoid cross forest permission issue (calendar permission,send as permission)

    when it comes to SFB Online, advanced pstn is not supported. In other words those in Exchange online cannot be added to response groups.

    Here you can migrated those who wont be using enterprise voice to SFB online. Don't think delegate in mixed mode is supported either. They have to be both on prem or online.

    For users who will use enterprise voice, but not be added to response groups, they can be migrated to SFB online.

    I would recommend to merge everything on-prem before going hybrid.

  • There is a nice TechNet article to discuss supported features under following scenarios

    Exchange 2013/2010 (on premise) + Skype for Business Server 2015 (on premises)
    Exchange Online + Skype for Business Server 2015 (on premises)
    Exchange 2010 (on premises) + Skype for Business Online
    Exchange 2013 (on premises) + Skype for Business Online
