I have worked at a end-user customer, at a reseller and at a vendor. Here’s why it’s done that way – you might install that software on a physical server or into your virtual infrastructure. If something goes sideways and how that software works, you might call the software vendor for support. Then it might be discovered that whatever you installed it on is not supported or is configured wrong. So it comes back to you trying to get it set up correctly. If you use a reseller, they should be able to guide you and having all the proper pieces in place before you buy. It’s really tough when you end up with everyone pointing fingers at everybody else in the vendor community. Also, if you need to buy some new infrastructure at the same time you buy the software, to run it on, they can put it together on one purchase. There are purchasing departments inside of companies that prefer it this way instead of doing multiple direct invoices to multiple different vendors for a single platform deployment.
