What Is Network Virtualization?

Network Virtualization will help enterprises of all sizes make the most of their current infrastructure

Network Virtualization represents the most significant innovation in networking since the inventions of Ethernet and the multi-protocol router, two technologies pioneered to level the playing field for  device connectivity. Network Virtualization is an emerging technology that will prove to be incredibly virtuous to enterprise IT. It will be foundational in enabling IT spend to shift more to the cloud.

While the benefits of cloud are widely understood and easily articulated in terms of agility, operational efficiency, better capital utilization, new consumption models, the benefits are hard to realize due to networking barriers. The networking barriers inhibiting multi-tenant cloud deployment are high. Inadequacies of earlier attempts to bring together networking and server hypervisor technologies have further exacerbated these issues, causing many enterprises either to enact fragile, static deployments models – or, worse, bypass the benefits of cloud entirely. We believe the cloud model should extend beyond simple virtualization to include all of infrastructure. Virtualizing the network is key to making this happen.

But more importantly, Network Virtualization will help enterprises of all sizes make the most of their current infrastructure, and will deliver a significant return on investment for internal organizational use. See, this could be very virtuous.

Network Virtualization starts with an architecture that decouples the physical from the virtual aspects of networks. The physical network of an organization continues doing the work it was designed to do. It forwards packets, using trusted and well understood routing protocols. The virtual network, however, manages and orchestrates. It maintains operational policies, including access control lists, configuration policies, and network services.

Network virtualization enables the creation of multiple virtual networks on top of network hardware. These virtual networks are topologically independent and have the same operational model of virtual machines found in server virtualization. They can be easily set up and torn down with no changes to the physical network substrate. Network virtualization, if done correctly, should be able to run any workload that is compatible with existing networks, over any type of hardware at any location.

Managed service providers offer a unique opportunity to fill those gaps and get organizations of all sizes on a hybrid cloud that meets their comfort level, while delivering enhanced benefits for cost, efficiency, agility, mobility, and elasticity.
DevOps has long focused on reinventing the SDLC (e.g. with CI/CD, ARA, pipeline automation etc.), while reinvention of IT Ops has lagged. However, new approaches like Site Reliability Engineering, Observability, Containerization, Operations Analytics, and ML/AI are driving a resurgence of IT Ops. In this session our expert panel will focus on how these new ideas are [putting the Ops back in DevOps orbringing modern IT Ops to DevOps].

Enterprises are striving to become digital businesses for differentiated innovation and customer-centricity. Traditionally, they focused on digitizing processes and paper workflow. To be a disruptor and compete against new players, they need to gain insight into business data and innovate at scale. Cloud and cognitive technologies can help them leverage hidden data in SAP/ERP systems to fuel their businesses to accelerate digital transformation success.
Most organizations are awash today in data and IT systems, yet they're still struggling mightily to use these invaluable assets to meet the rising demand for new digital solutions and customer experiences that drive innovation and growth. What's lacking are potent and effective ways to rapidly combine together on-premises IT and the numerous commercial clouds that the average organization has in place today into effective new business solutions.
Concerns about security, downtime and latency, budgets, and general unfamiliarity with cloud technologies continue to create hesitation for many organizations that truly need to be developing a cloud strategy. Hybrid cloud solutions are helping to elevate those concerns by enabling the combination or orchestration of two or more platforms, including on-premise infrastructure, private clouds and/or third-party, public cloud services. This gives organizations more comfort to begin their digital tr...
Keeping an application running at scale can be a daunting task. When do you need to add more capacity? Larger databases? Additional servers?
