Software Defined anything (SDx) is a movement toward promoting a greater role for software systems in
controlling different kinds of hardware - more specifically, making software
more "in command" of multi-piece hardware systems and allowing for
software control of a greater range of devices. Techopedia
With Software Defined Everything, the computing
infrastructure is virtualized and delivered as a service. In a Software-
Defined Everything environment, management and control of the networking, storage and/or data
center infrastructure is automated by intelligent software rather than by the
hardware components of the infrastructure - Webopedia

3.Software Defined Storage (SDS)4.Software Defined Data Centers
(SDDC)
Software Defined Network (SDN)
The physical separation of the network control plane from the forwarding plane, and where a control plane controls several devices.
Software-Defined Networking (SDN) is an emerging architecture that is dynamic, manageable, cost-effective, and adaptable, making it ideal for the high-bandwidth, dynamic nature of today's applications. This architecture decouples the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services.
Open Network Foundation (ONF)
Open Networking Foundation (ONF) is a user-driven organization dedicated to the promotion and adoption of SDN, and implementing SDN through open standards where such standards are necessary to move the networking industry forward.
Software Defined Network (SDN)
- Directly programmable- Agile- Centrally managed- Programmatically configured- Open standards-based and vendor-neutral
The key computing trends driving the need for a new network paradigm include:- Changing traffic patterns- The “consumerization of IT”- The rise of cloud services- Complexity that leads to stasis- Inability to scale- Vendor dependence
Software Defined Storage (SDS)
Software-defined storage (SDS) is an approach to data storage in which the programming that controls storage-related tasks is decoupled from the physical storage.

Software Defined Storage (SDS)
Software-defined storage (SDS) is an evolving concept for computer data storage software to manage policy-based provisioning and management of data storage independent of hardware. Software-defined storage definitions typically include a form of storage virtualization to separate the storage hardware from the software that manages the storage infrastructure. The software enabling a software-defined storage environment may also provide policy management for feature options such as deduplication, replication, thin provisioning, snapshots and backup. SDS definitions are sometimes compared with those of Software-based Storage.

Software Defined Data Center (SDDC)
A software-defined datacentre is an IT facility where the elements of the
infrastructure – networking, storage, CPU and security – are virtualised and
delivered as a service. The provisioning and operation of the entire infrastructure
is entirely automated by software.
Computerweekly
Software Defined Data Center (SDDC)
Software-defined data center (SDDC) is the phrase used to refer to a data center where
all infrastructure is virtualized and delivered as a service. Control of the data
center is fully automated by software, meaning hardware configuration is
maintained through intelligent software systems. This is in contrast to traditional data centers where the infrastructure is
typically defined by hardware and devices.
