It seems that almost everywhere the rush to “Cloud” and programmable infrastructure has generated a number of conversations around Software Defined ... Software Defined Datacetners (SDDC), Software Defined Compute (SDC), Software Defined Storage (SDS), Software Defined Networking (SDN), Software Defined Infrastructure (SDI) to name the predominant references. So many companies, consultants, etc. have started using the terminology but actually mean different things. So, what does IBM mean when we talk about Software Defined?
At IBM we see a bigger picture than just the Datacenter elements, we see a Software Defined Environment (SDE). Let's first talk about the progression of "Software Defined" and how we got here. Consider it a progression of Software Defined Environments 1.0, 2.0 and 3.0.
The progression as visualized above is something that has been happening for several years. Currently the industry is largely in the 2.0 phase and moving toward 3.0. Here is a brief description of the stages.
Software Defined Environments 1.0
To put this in perspective, consider that the IT industry is continuously on a transformational journey. The most recent transformation has been virtualization across all infrastructure platforms and elements. Virtualization started with Compute to better utilize compute resources which generated better ROI on compute and software investments.... [Continue Reading]
