Software Defined World
Software defined is an umbrella term describing how virtualization and abstracting workloads from the hardware it sits on top of can be used to make IT infrastructures more flexible.
Software defined data centres make digital all elements of the data centre infrastructure including networking, storage and security are delivered as a service. A data centre admin can deploy, provision and manage its infrastructure through software and automate as much of the processing as possible.
There are three main terminologies used under the SDN trend:
Software defined networking – network architecture to make network devices programmable, allowing the admin to adapt to business requirements.
Software defined storage – separates tasks from physical hardware, allowing the admin to pool and manage storage resources through policies and carry out configurations.
Software defined data centre – analytics driven approach to balancing the resources that application programs require in virtual and cloud environments.
