What is a Software Defined Data Centre (SDDC)?

  If “Cloud” is internet based computing, in which large groups of remote servers are networked to allow the centralisation of data storage and online access to computer services or resources, then “SDDC” is the method through which cloud services get delivered most efficiently. The foundation of the cloud is based on the concept of converged infrastructure and shared services.  Cloud resources are dynamically reallocated per demand. Cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance. “Moving to the cloud” refers to moving from the traditional CAPEX (capital expenditure) model where dedicated hardware is procured and depreciated over a period of time to the OPEX (operating expenditure) model where cloud infrastructure is used and paid for as it is consumed. Availability of high capacity networks, low cost computers and storage devices and the widespread adoption of hardware virtualisation, service-orientated architecture, automatic and utility computing has led to a growth in cloud computing. Physical servers were under-utilised and often undertook one task.  Virtualisation has allowed numerous virtual machines to be hosted on one physical server with the consequent reduction of costs.  Virtualisation is basically the masking of server resources, including the number and identity of individual physical servers, processors and operating systems from the server users.  Software allows one physical server to be divided into multiple isolated virtual environments. SDDC extends virtualisation concepts to all the data centre’s resources through process automation and the pooling of resources on-demand as-a-service.  Infrastructure is virtualised as a service ensuring that applications and services meet capacity, availability and response time.
