Software-defined data centre definition

Software-defined data centre (SDDC) refers to a data centre where infrastructure is virtualised through abstraction, resource pooling and automation to deliver Infrastructure-as-a-service (IAAS). Software-defined infrastructure lets IT administrators easily provision and manage physical infrastructure using software-defined templates and APIs to define and automate infrastructure configuration and lifecycle operations. 

Software-defined data centres are considered by many to be the next step in the evolution of virtualisation, container and cloud services.
