    Ok its not completly designed to be run locally but the only parts which are designed to be web-based are extra add-ons (such as SLG).

    The only parts of the Sims.net client (as it stands) which can put put through a browser are reports which you can pull out as HTML.

    Unless you put a lot of time and money into a self hosted SLG which a school local to me has but they have 2 full time web developers and have pretty much designed all there internal web applications around the Sims Learning Gateway webparts.

    Just to confirm a few things, Norfolk is hosted by Capita, not the LA. Like Phil said, it was a problem with the "indentity management". This would happen in a any "cloud" environment, even if SIMS was truely Web\Cloud-y. It's the problem with centrally hosted, I guess you could say it's also happen to centrally managed (ie push out and update and it kills everything)

    One thing to remember is the end-user, ie SMT, teachers and office users choice the MIS system, not techies, if we did, do you think FMS would still be going (at least as it is now)? If the best way to work is a Windows Application, a Windows Application it shall be and a expensive Terminal server job it shall be if it needs to be in a "cloud" environment. I agree the cloud will be the future, but it isn't there, it was Capita would swap overnight, they have the money. The proof is that Microsoft still sells Office 2010, they still have a huge roadmap for Azure and other cloud bits and they even still have articles stating cloud still isn't the answer for all applications. Come on Bromcom, we know Windows Apps in terminal isn't true cloud, we've heard it all from Microsoft and Google.

    Not "run locally" does not mean "web based" (browser based). Most web based applications that exist beyond the very simplest, use Javascript or other client side scripting to achieve an 'acceptable' user experience. A significant amount of the processing in SIMS is done at the database by stored procedures which control access to the underlying database schema (witness the number of posts on MsSQL databases chewing up processor time). You could theoretically abstract that processing to an intermediate server and have a dedicated server running the stored procs while a separate server deals with the pure SQL. Hence the term N-Teir.

    The difference between the client side footprint of a .net application and a browser, both of which are primarily concerned with rendering the interface and performing client side validation, is somewhat moot when you consider the rich use of AJAX (and the likes) which a most 'web based' applications make significant use of for client side processing.

    Meanwhile unless Bromcompublicrelations has detailed knowledge of exactly what issue has caused problems, there is nothing to say that the issue -whatever it is - wouldn't result in a failure of a centrally hosted web application. In terms of describing SIMS .net as "designed to run locally", as Wolfgang Pauli once said - "it's not even wrong".

    (something like £20000 to £30000 saving when going hosted, if memory serves)
    How can it be. All my primary schools have a single server running everything, AD, SQL, Sims, FMS, Printers, Apps.

    So no extra cost for hardware or backups and the rest as it's already in place. Just have to pay for support and licence which should be way way cheaper than 30K.

    Have I missed something or not understood.

    I would image they would be doing like-for-like, so Central hosted would have "a" server with a SLA - ie 4 hr response etc, therefore local would need "a" server with a SLA. Support costs for a cluster of servers in one place would be better that a number of servers over a spread area. Equally the number of servers would less.

    I doubt it would take into account existing servers, auditing costs would push costs up dramatically.
