Software-Defined Infrastructure

Software-Defined Infrastructure (SDI) refers to the abstraction of physical infrastructure into a software-based environment that can be programmatically managed and controlled. With SDI, infrastructure like servers, storage, and networking are virtualized and delivered as a service.

SDI allows infrastructure to be dynamically provisioned and managed through software APIs and automation tools. For example, with SDI a developer can request new virtual servers or storage capacity on-demand through a self-service portal. The SDI software layer handles provisioning the required physical resources automatically without manual intervention. Key benefits of SDI include increased agility, flexibility, automation, and efficiency in infrastructure management. Popular SDI technologies include software-defined networking (SDN), software-defined storage (SDS), and infrastructure-as-code (IaC) tools like Terraform that enable programmable infrastructure through code. Overall, SDI provides a modern, flexible abstraction layer above physical hardware that allows dynamic and automated infrastructure management.
