Summary Software-defined networking (SDN) and network functions virtualization (NFV) are the technologies driving next generation network transformation; but the factors impacting faster SDN/NFV adoption are the same ones slowing the road to 5G. While there are many technical challenges, it comes down to the fact that this is a paradigm shift. Running a hybrid networking environment can be challenging; communications service providers (CSPs) simply can’t afford to interrupt mission critical services inadvertently while upgrading their networks. Also, investing in network transformation takes buy-in internally and…
Why should we care about monitoring and visibility into Software Defined Wide Area Networks (SD-WAN) in the first place? Well, for one thing, analysts’ consensus estimates that the SD-WAN market will grow from roughly $90M in 2017 to over $4B in 2020. Digital economy demands agility in responding to user requirements and delivering superb user experience. The former is achieved via agile development and various software defined technologies. The latter has to be managed. SD-WAN is the software defined networking solution for the edge and…
I remember leaving camp with my parents on visiting day, late 70s, New Hampshire. It was hot and sticky and bright green out as we drove to from Lake Arlington to Hanover, to the Dartmouth campus and the Kiewit Computation Center. Inside was cool and crisp. White and sterile, with the hint of a hum among the rows of machines. On display was connectivity, and it was mesmerizing. A few years later, in 1982, I leveraged this family memory and asked my father for an…
The global digital transformation market is expected to continue to grow. At the forefront of that transformation are Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies, which are creating new opportunities to redefine the customer experience by delivering agile and on-demand services. While there’s a lot of industry buzz about these services as we approach ONUG Spring 2018 in San Francisco, and many people generally understand SDN and NFV technologies, there seems to be a gap when it comes to the practical application…
The world of networking is undergoing a major shift over the past few years. Micro services and containers in application stack has put new challenges to networking engineers across enterprises to build a faster and leaner network stack. Greater visibility into end-to-end network flow and granular control is another big requirement. It means that organizations need to keep up with the agility of ever-changing application landscape. In fast-paced environment, network agility can be achieved through Software Defined Networking (SDN), Network Function Virtualization (NFV) and Programmable…
The more networks have evolved and the more complex data center architectures have become, organizations are realizing they’ve got time bombs latent in their network, just waiting for the right set of circumstances to take down critical portions of their infrastructure. In the past, a configuration error might cause a blip in the network that went unnoticed. With today’s networks so intimately tied to business, each error can cost many millions of dollars and become front-page news. A surprisingly simple way out of this dilemma…
If software is indeed moving to the cloud, new tools will be required for debugging when errors culminate into outages. This is due to the reliance on higher level abstractions through monitoring now that there is no physical access to the servers running the applications. Lately, I’ve been thinking a lot about the types of assurances (and startup solutions) enterprises will need in a cloud native world to guarantee uptime. Site Reliability Engineering is a functional role in most businesses today, but has seen a…
Public clouds can be a blessing and a curse. They’re easy to use in limited ways, but hard to turn into a strategic resource. To make them an effective part of an enterprise infrastructure, there’s work that has to be done and it’s not insubstantial. Most enterprises are using multiple cloud providers through relationships that look more like accidents than careful planning. A development team started using one provider, while a partner had resources in another. A mobile app had its back end in a…
SDxCentral Research is pleased to announce the availability of our 2018 edition of our Next Gen Data Center Networking Report. After the enormous success of last year’s inaugural edition, we’ve been hard at work updating the report for this year. Cloud computing, software-defined networking (SDN), and network virtualization have radically changed the way data centers are being networked. Networking platforms need to be designed and built to handle the massive scale of today’s web and cloud applications – with flexible software control that can dynamically react to changing…
How many networks are you running today? And how many vendors are involved in your network infrastructure? Today’s IT teams are using whatever networks are the fastest and most cost-efficient to deliver applications. This includes public internet, MPLS, WAN, LAN, WiFi and more, all depending on business needs and locations. Public internet use has grown in enterprises because of its lower cost. There are tradeoffs, of course, like the lack of performance guarantees or much in the way of provider promises. As public internet use…
