What is SDD?

SDD can refer to several technologies. Without more context, it's ambiguous. Here are a few possibilities: * **SDD as in Software Defined Datacenter:** A software-defined data center (SDDC) is a data center where all infrastructure is virtualized and delivered as a service. All hardware infrastructure is abstracted through software. * **SDD as in Software Defined Disk:** This could refer to storage virtualization or software-defined storage (SDS), where storage resources are managed and abstracted through software, independent of the underlying hardware. * **SDD as in Structured Systems Analysis and Design (SSAD):** This is a traditional software development methodology. It uses structured techniques to analyze and design systems. SSAD methodologies involve data flow diagrams (DFDs), entity-relationship diagrams (ERDs), and structure charts. It's not a technology per se, but a framework. * **SDD as in Solid-State Drive:** While more commonly abbreviated as SSD, SDD can sometimes refer to Solid-State Drives. These are storage devices that use flash memory to store data.
