Demystifying the Software-Defined Data Center (SDDC), the HP Point of View

In our globalized and highly changing business world, IT organizations need to align as fast as possible with business requirements. This demands a lot of innovations be put in place around data center technologies and the Software Defined Data Center (SDDC) is a reasonably new concept in line with this demand. The SDDC promises to align business and IT like never before by providing open choices regarding the optimization of IT consumption models to deliver maximum agility, security, and business value.

 

Let’s begin by defining what SDDC is. In my opinion SDDC is the evolution of datacenter in line with IT organizations vision to align with the business. The software defined approach in the data center enables IT to optimize the rapid creation and delivery of business services, reliably, through programmable infrastructure. This is implemented, with a reference architecture that uses policy-based automation. This automation is available from the infrastructure up to the application level, using a unified view of physical and virtual resources.

 

The SDDC reference architecture is defined in three layers: an infrastructure layer, a control layer and an application layer. The bottom layer is the infrastructure layer which includes cross-domain infrastructure components. This layer is divided into two with an underlying physical Infrastructure (which mainly consists of a commodity hardware) and an overlaying virtual infrastructure (which consists of an abstracted pool of infrastructure resources). The virtualization technology plays a pivotal role to abstract the different domains into a horizontal layer and offer a unified physical and virtual view. This unified view provides an open standard-based programmatic access to disparate physical and virtual infrastructure resources and platforms.

 

The middle layer is the control layer or management layer, which is the core of the SDDC reference architecture.  This layer creates abstractions (SW defined constructs) of infrastructure resources to support application or business service requests. The control layer enables IT admins and Line of Business (LOB) folks with application level controls. This is achieved through set of activities including policy orchestration, change automation and infrastructure monitoring.

The third layer is the application layer, which consists of business applications and their related infrastructure applications. This layer consumes infrastructure resources as a service and enables a better business alignment.

Among these three layers, the middle layer controls the infrastructure and ensures adequate resources for the application layer. Because of this it is very important to focus on the middle control layer to have a successful SDDC implementation. This is why we here at HP Software are innovating around SDDC management and specifically the control layer.   For more information,  visit the HP vPV website for more details about our SDDC management continuum.
