In the good old days (rose-tinted spectacles required), there was only one operating system in the stack. It took care of device drivers and file IO. There were many flavours of OS, depending on the period, from UNIX and Windows to OS/2 and MacOS, and many, many others. Over time, the selection of operating systems in the data center reduced down to Linux and Windows (there are still holdouts for others, for various specific reasons, but Linux and Windows hold about 90% of the OS market). There are many flavours of Linux, but all an app developer in the enterprise really needs to know is which OS they are targeting. More and more, even that level is too low down for the app developer who is looking more at the middleware to make the final decisions.

On 4/12/2012, EMC in conjunction with technology partners VMware, Microsoft, Cisco, Brocade, Citrix and Intel announced EMC VSPEX. EMC VSPEX is an specification framework that allows multiple vendors to participate in providing “standard” building blocks for virtualized data centers and private clouds – targeted at accounts who need less than 250 virtualized servers and/or 2000 virtualized users (VDI) and delivered exclusively through EMC/VMware/Cicso/Microsoft/Citrix partners. The goal of this initiative is to provide the mid-market with cost effective, pre-certified, pre-integrated solution sets and leverage standard building blocks from leading vendors. In other words this is VCE/vBlock for smaller companies delivered through the distributor and VAR channels of the respective vendors.
