An SDDC (software-defined data center) is a data storage facility in which all infrastructure elements — networking, storage, CPU and security — are\u00a0virtualized\u00a0and delivered\u00a0as a service. Deployment, operation,\u00a0provisioning\u00a0and\u00a0configuration\u00a0are abstracted from hardware. Those tasks are implemented through software intelligence. Former VMware CTO Steve Herrod is widely credited with coining the term around 2012.<\/p>\n\n\n\n

An SDDC is currently more of a concept than a commonly implemented practice, but it has seen incremental adoption by\u00a0cloud service providers\u00a0and\u00a0data-center-as-a-service\u00a0providers. The list includes Amazon, Google and the Open Compute Project.<\/p>\n\n\n\n

Components of an SDDC<\/strong><\/h1>\n\n\n\n

Virtualization is central to the software-defined data center. There are three major SDDC building blocks:<\/p>\n\n\n\n

  • Network virtualization<\/strong>\u00a0combines network resources by splitting the available bandwidth into independent channels that can each be assigned — or reassigned — to a particular server or device in real time.<\/li>
  • Storage virtualization\u00a0pools<\/strong>\u00a0physical storage from multiple network storage devices into what appears to be a single storage device managed from a central console.<\/li>
  • Server virtualization<\/strong>\u00a0masks server resources, including the number and identity of individual physical servers, processors and operating systems (OSes), from server users. The intention is to spare users from managing complicated server-resource details. It also increases resource sharing and utilization, while maintaining the ability to expand capacity at a later date.<\/li><\/ul>\n\n\n\n

    A business-logic layer is needed to translate application requests, policies and\u00a0service-level agreements.<\/p>\n\n\n\n

    SDDC benefits and challenges<\/h3>\n\n\n\n

    A software-defined data center is a way to dynamically configure and provision applications, infrastructure and IT resources. The design allows the data center to be managed as a unified system or aggregate set of domains. A key factor is the separation of\u00a0control planes\u00a0and\u00a0data planes.<\/p>\n\n\n\n

    An SDDC provides an organization with its own\u00a0private cloud\u00a0for better control of hosted data.<\/p>\n\n\n\n

    Software-defined data centers capitalize on the\u00a0agility<\/strong>,\u00a0elasticity<\/strong>\u00a0and\u00a0scalability<\/strong>\u00a0of\u00a0cloud computing. The chief advantage is automating all functions through intelligent software, especially manually intensive tasks related to provisioning and operational management.<\/p>\n\n\n\n
