How NFV (Network Function Virtualization) Empowers Hybrid Cloud?

No other technology endeavor is fraught with as many complexities and challenges as hybrid cloud, especially when it comes to creating an effective interconnecting layer that allows the diverse platforms to work cohesively. Thus, it becomes imperative for CIOs to ensure their cloud service providers have built the right virtualized backbone to offer true hybrid offerings.

Hybrid cloud is indeed fast gaining significant grounds as the solution for enterprises to better manage scalability and flexibility of an IT ecosystem that is able to address dynamic business needs. CIOs are increasingly looking to move onto hybrid environments coupling the integrity and personalization of private clouds with agility and scale of public clouds.

So far so good, but there’s a problem: no other technology endeavor is fraught with as many complexities and challenges as hybrid cloud, especially when it comes to creating an effective interconnecting layer that allows the diverse platforms to work cohesively. It becomes imperative for CIOs to ensure their cloud service providers have built the right backbone to offer true hybrid offerings.

The fundamental complexity of connecting diverse cloud computing environments is that the various networks across private clouds, virtual private clouds, on-premise or hosted datacenters, and public clouds are disparate. Varying architecture and processes add on to the operational burden and inhibit interoperability.

By definition, a cloud depends on a very high degree of automation of the underpinned resources. While compute and storage have been easier to virtualize and automate, the network didn’t match the pace, hindering hybrid cloud being enabled in its truest sense.

This is where Network Functions Virtualization (NFV) greases the wheels. Simply put, it helps enterprises building their own ecosystems or cloud service providers to seamlessly deploy, manage and scale their networking interconnects by decoupling specialised hardware from network services and running them on software-driven, standardized, commodity hardware.

How NFV Helps
CIOs looking to approach hybrid clouds, need to ensure they select the right cloud partners that have been transforming their networks to software-defined models and liberate themselves from the static and inefficient operating paradigms. Such cloud players must offer new service offerings that offer seamless extensibility of networks across diverse computing platforms and help derive the best value.

By decoupling network functions from dedicated hardware, NFV allows VMs to take over the network services and build a dynamic service chain as required. This capability not only cuts down the time to provision but also significantly reduces costs. With NFV, the cloud applications become truly mobile. This adds phenomenal agility to the computing environment to effectively address changing business needs and network demands. NFV also helps accentuate operational automation further and simplify processes and planning. Perfectly complementing a Software Defined Network (SDN), NFV allows cloud players and/or enterprise IT teams to deploy, allocate, monitor, recover and upgrade underlying resources and services across the hybrid environment, programmatically and without human intervention.

The potent combination of NFV and SDN helps cloud players, like Netmagic, to build effective cloud management system that offers a greater degree of openness, interoperability, and agility for diverse enterprise workloads and applications to leverage seamlessly integrated hybrid cloud services.

NFV is all about moving at the pace of software. CIOs need to select the right hybrid cloud service partner that leverages such new-age technologies to provide unrestrained and boundary-less networks that seamlessly enable growth and respond to dynamic needs at an almost real-time.
