Storage Virtualization:

Storage virtualization in Cloud Computing is nothing yet the sharing of physical storage into various storage devices which further has all the earmarks of being a single storage gadget. It very well may be additionally called collectively of an accessible storage gadget which just oversees from a central console.

This virtualization provides numerous benefits such as easy backup, achieving, and recovery of the data.

This entire cycle requires exceptionally less time and works in a proficient way. Storage virtualization in Cloud Computing doesn’t show the genuine intricacy of the Storage Area Network (SAN). This virtualization is material to all degrees of SAN.

How it works:

To give admittance to the information put away on the physical storage devices, the virtualization programming needs to either make a guide using metadata or, now and again, utilize a calculation to progressively find the information on the fly. The virtualization programming then, at that point, intercepts read and compose demands from applications and using the guide it has made it can find or save the information to the proper physical gadget. This interaction is like the strategy utilized by PC operating frameworks while retrieving or saving application information.

Storage virtualization disguises the actual complexity of a storage system, such as a SAN, which helps a storage administrator perform the tasks of backup, archiving and recovery more easily and in less time.

Network Virtualization:

The ability to run multiple virtual networks with each has a separate control and data plan. It co-exists together on top of one physical network. It can be managed by individual parties that potentially confidential to each other. Network virtualization provides a facility to create and provision virtual networks — logical switches, routers, firewalls, load balancer, Virtual Private Network (VPN), and workload security within days or even in weeks.

How it works:

Network virtualization decouples network services from the underlying hardware and allows virtual provisioning of an entire network. It makes it possible to programmatically create, provision, and manage networks all in software, while continuing to leverage the underlying physical network as the packet-forwarding backplane. Physical network resources, such as switching, routing, firewalling, load balancing, virtual private networks (VPNs), and more, are pooled, delivered in software, and require only Internet Protocol (IP) packet forwarding from the underlying physical network.

Network and security services in software are distributed to a virtual layer (hypervisors, in the data center) and “attached” to individual workloads, such as your virtual machines (VMs) or containers, in accordance with networking and security policies defined for each connected application. When a workload is moved to another host, network services and security policies move with it. And when new workloads are created to scale an application, necessary policies are dynamically applied to these new workloads, providing greater policy consistency and network agility.
