NFV: What You Should Consider in Your ADCs

March 12, 2015 — by Jim Frey0

Network functions virtualization (NFV) is one of the best-accepted and most-understood spinoffs of the SDN craze that has taken root over the past few years. The concept is straightforward: take features and capabilities that are typically implemented in the network and repackage them in forms that can be invoked automatically, without requiring the deployment of new hardware.

SDN Use Cases: Myths and Realities

There were a lot of promises made when software-defined networking (SDN) first came onto the scene, and while some real benefits have been experienced, not all promises have been realized, or were even realistic. Such is commonly the case with new technologies: the initial hype exceeds the reality of the situation, but usually there are reasons to hold firm to the trend and take advantage of what the technology does deliver successfully.

LBaaS: Load Balancing for the Age of Cloud

As organizations embrace the cloud, whether as enterprises looking to transform IT or providers expanding and enriching service offerings, traditional IT/networking technologies must be adapted to fit the form of the new reality. This is certainly true of load balancing (LB) as well as application delivery control (ADC), which has undergone virtualization and software programmability/orchestration evolutions.

Transformation of the Data Center & Building the Private Cloud, Part 2

In Part 1 of this blog, we looked at the growing adoption of cloud and Software-Defined Datacenter (SDDC), but also the fact that network virtualization choices are many and varied, creating some uncertainty regarding how to proceed.  In part 2, we will look at network virtualization options and how to align for best success.

Transformation of the Data Center & Building the Private Cloud (Part 1)

In order to remain engaged and relevant in the long run, a growing percentage of enterprise IT organizations are seriously considering transforming themselves into internal private cloud service providers. The requisite enabling technology is virtualization across all three primary technology domains – compute, storage, and network – combined with a healthy dose of automation and orchestration. Server virtualization is the most mature, and has taught us much with regard to automation and improving IT agility, fueling a desire to extend the model and achieve fluid architectures such as the Software Defined Data Center (SDDC).

The Year of the (SDN) App

While there is still work to be done, Software-Defined Networking (SDN) is making steady strides towards achieving the viability and maturity needed to become a foundational element of networking in both enterprise and service provider settings.  One of the key indicators of progress has little to do with the basics of SDN technology itself, but with the growing number of applications designed to leverage and interact with SDNs.  This is creating a “pull” that is every bit as important as the “push” of revolutionary infrastructure technology.

Coping with the New Era of Application SLAs

The steady moves toward internal/external cloud computing, virtualization, more complex web applications, BYOD, the App economy and new strategies for dealing with cyber attacks are bringing disruptive change to IT.  These changes are mostly for the good, but along the way that have created a litany of new pain points and challenges.

Application Delivery in the Age of SDN

As the dust begins to settle from the hype storms around Software Defined Networking (SDN), one result is clear – we will never look at IT infrastructure, and networking in particular, in quite the same way again.  And while much of the sniping and scrapping has been aimed at those seeking to commoditize the lowest layers of the network thus far, the long range objective of SDN is to bind network function more directly to the needs of the application layer in a secure, policy-oriented manner.  While the essential enabling technologies have been proven out in a few high profile large-scale deployments, mainstream adoption will be gated by the maturity at the touch points between network consumers (a.k.a. applications and services) and the new network control architecture.
