CA Service Catalog - max amount of Business Units

  • 1.  CA Service Catalog - max amount of Business Units

    Posted 05-21-2019 03:45 AM

    Dear friends

    We have a customer who supports more than 11000 organizations. The need is to set up SC security in a way that every user is able to access any request from his/her organization. This means that every organization should represent a BU.

     

    Are there any performance issues for such a large number of business units?

    Is there another way how to meet customer needs? Some form level checks?

     

    Thank you,

    Jakub

    Hi Jakub.

     

    There's no hardcoded limit, and I've seen a few sites running with thousands of defined units, yes. But more than the performance hit I'd be concerned about how you set these units up to be manageable going forward - is this to be a very flat structure with only a few providers, or are units several layers deep?

     

    thanks

    Iain

    Hi Jakub.

    Some 'things' to consider:
    - Wow, that's a lot of business units. I've seen thousands from a few sites, but it is indeed a performance hit.
    - And a **** of a job to maintain so many BUs holding so many offerings probably/accordingly and so many users then too(even more users I guess).

     

    Also to be considered:

    - How can this amount be handled through teh Catalog UI? Or even (in bulk) with SOAP webservices programs?
    - How do you keep an overview of BU>SUB-BU-Catalog content (allowed for each BU)
    - How do you keep an overview of BU>SUB-BU-User (allowed for each BU)
    - Physically, there is no limit, but for your organization.......

    Thanks and kind regards, Louis.

    Louis_van_Amelsfort, IainLambert

    thank you for your suggestions!

     

    All users and organizations are maintained in a separate system which updates users and organization in CA SDM. All users are then imported/updated in the AD LDS for authentication and authorization purposes. Users have the same set of services (only about 7 services at all) so the original idea was to have only one BU for all the users, but there is this need that every user should access all tickets from his organization...

     

    So I guess the correct setup is to have a completely flat structure managed by an external script (web services). Is this a correct thought? I'm an SDM guy and don't have many experiences in CA Catalog... 

     

    At first glance at CA SC web services, I don't see anything regarding business units management. Is there a possibility to maintain BU and SC users via WS? Or some bulk uploads/updates?

     

    Maybe this can be solved on the form level - considering there are only 7 services I can manage some test during form onLoad - something like:

    • run a query for the current user to get his organization
    • compare the organization with the end user organization
    • if the organization is different stop loading the form

    This is not a very nice solution but should be easy to develop and maintain

     

    Thank you for your time,

    Jakub

    Hi IainLambert,

    We don't (and can't) use multitenancy for this implementation - we implement catalog widgets as a front-end for already existing SDM implementation which has many integrations so multitenancy is not an option for us.

     

    Thank you,

    Jakub

    Hi Jakub.

    In the above example, running the SOAPUI utility, the "http://HOST:PORT/usm/services/BusinessUnitService?wsdl"

    can be used to manipulate BUs in bulk/batch.

     

    Kind regards, Louis.

     

    Still I would like to advise that managing 10.000 BUs is almost impossible to do.

    Technically, probably. Human-wise, not to do. :-)

    Great, thanks for the WS example!  I'll give it a try...

     

    I completely agree that managing such a huge number of business units is not very comfortable, but I have to deal with the business requirement which is clear and (in this case) also reasonable... And I don't see other options

     

    Thank you again,

    Jakub
