hi Tauf You make a very good and critical point: that you are sharing the DB with other companies. This is very critical. You would users from some companies doing "bad queries", or running exhaustive reports, that perform multiple full table scans. In a shared DB environment, and in the specific case of Remedy, a shared DB instance, this impacts all the users and therefore all the companies/customers. Very bad situation. From a DB administration and performance tuning perspective, it becomes harder to analyze and troubleshoot performance, and to pinpoint what queries are responsible for the degraded performance and by what users.
It seems to me a "fair" approach would be to segregate/dedicate the database instances per customer, which means that each customer would need to have its own Remedy application server, since only one application server can connect to one database instance. However, you still have the issue of shared storage to deal with, that also would need to be configured to equally provide storage resources equally among all the databases, and therefore among all the customers. Sharing infrastructure is already complex and wrought with issues within a single customer (for instance sharing your SAN and database server between let's say Remedy, Finantial, HR apps) now sharing infrastructure between different customers is even worse. the more we analyze this topic,the more we see that SaaS (whether BMC or Service-Now or Micky Mouse Inc) has many problems.

However, I do see an opportunity for companies that cannot afford or maintain multiple environments to use the SaaS platform to host a “Training” environment. If there weren’t so many restrictions you could possibly do Dev as well but since it is locked down and you share your DB with other companies, this could be an impossibility. Maybe BMC has answers to this and maybe they don’t but the presentation didn’t give me the “warm and fuzzies” about it. Tauf Chowdhury | Forest Laboratories, Inc.

So I think it's more like what kind of applications are appropriate for SaaS. I don't think a full-blown BSM/ITSM implementation with all the modules, all the integrations, all the reports, etc, etc can work as SaaS. But I can very well envision small, targeted and generic applications built on Remedy and provided as a software subscription service.

I was at the Column Roadshow in NYC where the BMC rep presenting Remedy OnDemand got hammered on issues with the SaaS platform. Mainly, it was around the “loss” of control and limited support of customizations. There were also issues around upgrades. Have any of you given this a thought? It provided for some entertaining dialogue last night so it should be even more so here on the list! Tauf Chowdhury | Forest Laboratories, Inc.
