Network World Networking
CIOs, network administrators and data-center managers who see a need to run full-fledged, unmodified enterprise software at the edge of their networks, on factory floors and oil rigs, now have an opportunity to do so.
HPE is certifying complete enterprise software stacks for its EdgeLine converged infrastructure devices, allowing enterprises to run the exact same applications in the data center, in the cloud or at the network edge.
The certifications will cover software from vendors including Microsoft, SAP, PTC, SparkCognition and Citrix to run on its EdgeLine EL 1000 and EdgeLine EL4000 systems, the company said Wednesday at its Discover conference in Las Vegas.
When I began my journey in 2015 with SD-WAN, the implementation requirements were different to what they are today. Initially, I deployed pilot sites for internal reachability. This was not a design flaw, but a solution requirement set by the options available to SD-WAN at that time. The initial requirement when designing SD-WAN was to replace multiprotocol label switching (MPLS) and connect the internal resources together.
Our projects gained the benefits of SD-WAN deployments. It certainly added value, but there were compelling constraints. In particular we were limited to internal resources and users, yet our architecture consisted of remote partners and mobile workers. The real challenge for SD-WAN vendors is not solely to satisfy internal reachability. The wide area network (WAN) must support a range of different entities that require network access from multiple locations.
HPE's pledge to pump billions of dollars into developing edge systems shines a light on the company's ambition to be the leading end-to-end computing infrastructure provider.
CEO Antonio Neri made the investment announcement at the company's Discover conference Tuesday in Las Vegas, in his first appearance at the company's annual event as chief executive. He took over the CEO role from Meg Whitman in February.
Agility and speed are of paramount importance for most organizations as they try to innovate and differentiate themselves from the competition. The need for flexibility and rapid scalability is driving more and more companies into the cloud, as traditional data centers are no longer proving to be competitive, agile or robust enough.
It should come as no surprise that Cisco predicts 94 percent of workloads and compute instances will be processed by cloud data centers by 2021. But deciding when to take the leap, weighing the costs and risks, and developing a successful strategy is easier said than done. Let’s take a closer look at why companies are ditching those data centers and how they can make the transition as smooth as possible.
As the world has become more cloud- and IoT-centric, the network has increased in value. That is why there has been so much focus on network evolution, particularly in the data center and the wide area network.
One part of the network that has lagged in innovation, however, is the network edge. Over the years, the edge of the network has been considered by many to be a commodity. And for many businesses, it is in dire need of a refresh. I’ve talked to some organizations that are running network edge infrastructure that’s approaching 10 years old and haven’t even had a software upgrade in years.
The network edge needs to evolve
However, in the words of the esteemed song writer Bob Dylan, “The times, they are a changing” — and so is the role of the network edge.
Net neutrality officially ended on June 11, 2018, and many people are concerned that this is the end of an open internet. Many supporters of it believe the internet should be regulated no different than the phone system or power utility and that this change will decrease the performance of it. Opponents of net neutrality, argue that the end of it will now increase competition among the various internet service providers (ISPs) and increase coverage, improve performance, and lower costs.
What is net neutrality?
Net neutrality became effective by the Federal Communication Commission (FCC) under President Barack Obama in 2015. It is a set of rules that ensured ISPs treated all data transmissions, irrespective to content, that flowed through their infrastructure equally. Net neutrality protections prevented ISPs from slowing web services, blocking access to sites, or charging content organizations for faster delivery of streaming movies or videos. It is believed that antitrust laws did not go far enough in ensuring that all content received equal treatment.
David Goeckeler doesn’t wear all of the hats at Cisco but he certainly wears one of the biggest.
Responsible for 20,000 engineers and $32 billion worth of the networking giant’s business, Goeckeler, executive vice president and general manager, masterminds Cisco's network and security strategy which now features ever more emphasis on software. In fact, at the recent Cisco Live, Goeckeler emphasized that notion saying, “all the routers and switches and wireless access points (and in big networks there are going to be tens of thousands of those in a single enterprise network) we're thinking about that as one large software system.”
A new global backbone provider emerged from stealth last week, giving organizations even more choice in how they build their Internet-based SD-WANs. Mode introduced what it calls a “software-defined core” (SD-CORE) network that offers IT “affordable private-network reliability and quality of service” across the globe.
The company joins Aryaka and Cato Networks as one of the few independent backbone providers helping enterprises solve the variability problems of the Internet core. Middle-mile performance forms the biggest challenge for delivering stable, global, low-latency connections.
Software and programmable intelligent networks were hot topics at Cisco Live last week, and one of the key components of that discussion was the direction of the company’s SD-WAN strategy.
Central to that dialog is how Cisco plans to use and integrate the SD-WAN technology it acquired last year when it bought Viptela for $610 million. For the moment, Cisco says Viptela has brought with it interest to the tune of about 800 new customers in recent months.
Applications have become a key driver of revenue, rather than their previous role as merely a tool to support the business process. What acts as the heart for all applications is the network providing the connection points. Due to the new, critical importance of the application layer, IT professionals are looking for ways to improve the architecture of their network.
A new era of campus network design is required, one that enforces policy-based automation from the edge of the network to public and private clouds using an intent-based paradigm.
The race to automate
An autonomous network was once seen as part of a utopian ideal, albeit one far off into the future. It would make up the backbone of everything we did, managing a hyper-connected world in which everything from the minutiae of knowing when the milk in the fridge needed replacing, to the ability of the network to automatically ramp services up or down, without the need for human intervention.
In a recent ACG Research survey of network service providers, internet content providers, cloud service providers and large enterprises, 100 percent of respondents said they felt the need to pursue automation, and 100 percent are optimistic about automation’s future. Additionally, 75 percent of respondents indicated that they’ll have full or significant network automation within the next five years.
Cisco’s annual user event, Cisco Live, is being held in Orlando, Florida, this week. While Orlando is home to DisneyWorld, Universal Studios and other places where fantasies come true, the one thing that isn’t make-believe is the turnaround of Cisco since Chuck Robbins took over as CEO. When the baton was passed to Robbins in August of 2015, Cisco’s stock was trading at about $25/share and had been moving sideways for years. Today, it’s trading at about $45/share and at a 17-year high, and the turnaround is well underway.
Cisco goes back to the network
How did Robbins get Cisco’s mojo’s back in such a short period of time? The answer lies in its roots and a refocus on the network. In fact, when Robbins took over as CEO, I wrote a post outlining some priorities for him as he stepped into the role. My first point was to approach IT through the lens of the network. In the years leading up to the transition to Robbins, I felt Cisco had tried too hard to prove itself as a server and traditional IT vendor instead of staying true to networking.
ORLANDO – Cisco’s developer program, DevNet, is on a hot streak.
Speaking at Cisco Live 2018, DevNet CTO Susie Wee said the group, which was founded in 2014, now has 500,000 registered members.
"That’s a pretty cool milestone, but what does it mean? It means that we've hit critical mass with a developer community who can program the network," Wee said. "Our 500,000 strong community is writing code that can be leveraged and shared by others. DevNet is creating a network innovation ecosystem that will be the hub of the next generation of applications and the next generation of business."
At Cisco Live the company also announced it has expanded the DevNet world to include:
When it comes to computing, living on the edge is currently all the rage. Why? Edge computing is a way to decentralize computing power and move processing closer to the end points where users and devices access the internet and data is generated. This allows for better control of the user experience and for data to be processed faster at the edge of the network – on devices such as smartphones and IoT devices.
As enterprise organizations look to extend their corporate digital channel strategies involving websites with rich media and personalized content, it is vital to have a strong resiliency strategy.
Deploying a combination of cloud and edge services can help by: reducing unplanned downtime; improving security and performance; extending the benefits of multi-cloud infrastructure; speeding application development and delivery; and improving user experience.
2018 is shaping up to be a banner year for all things Ethernet.
First of all, the ubiquitous networking technology is having a banner year already in the data center where in the first quarter alone, the switching market recorded its strongest year-over-year revenue growth in over five years, and 100G Ethernet port shipments more than doubled year-over-year, according to a report by Dell’Oro Group researchers.
The 16-percent switching growth was, "driven by the large-tier cloud hyperscalers such as Amazon, Google, Microsoft and Facebook but also by enterprise customers,” said Sameh Boujelbene, senior director at Dell’Oro.
Since the advent of the internet and IP, networking technology has not seen a seismic shift of this magnitude that is occurring in Enterprise networks today. As organizations move from on-premises application hosting to a cloud-based approach, they are inundated with the inherent challenges of legacy network solutions. The conventional network architectures in most of today’s enterprises, were not built to handle the workloads of a cloud-first organization. Moreover, the increasing usage of broadband to connect to multi-cloud-based applications have escalated concerns around application performance, agility, and network security.
Software-defined WAN (SD-WAN) has gained immense traction among CIOs lately. Gartner forecasts that SD-WAN will grow at a 59% compound annual growth rate through 2021 to become a $1.3 billion market. This is because there are a myriad of payoffs of moving to SD-WAN: Primarily, SD-WAN enables easier access to cloud and SaaS based applications for geographically distributed branch offices and mobile work force. Here are but just a few other important benefits that SD-WAN brings to digital-first organizations:
In a previous blog post, 5 reasons to buy refurbished Cisco equipment, I talked about five facts to keep in mind as you consider how to proceed with your Cisco hardware solutions.
Well, my engineering group reminded me of something else to consider for any hardware solution, not just a Cisco solution.
It seems that cabling can be an afterthought. Sure, you just used a blended solution of new and pre-owned hardware, where each makes the most sense in your infrastructure and creates a unique and potentially game-changing opportunity to maximize value in your investments.
Traditional location positioning such as GPS isn’t going to be suitable for a Location of Things world filled with Internet of Things (IoT) sensors, say experts. The centralized, anchor-like system we use now, as found in GPS, mobile network cell tower positioning services, and Wi-Fi-based location positioning, is going to be a problem. The usual suspects being bandwidth, excessive power use, and cost.
The problem is IoT devices are required to communicate with positioning anchors, whether it be satellites or radio towers. That’s bandwidth-intensive; it can use a significant amount of power to cover the distances, as well as to power the multiple chips needed. The system is also conceivably susceptible to congestion as the numbers of devices increases — projections are for billions and billions of IoT things worldwide, ultimately.
Options. Everyone needs options. Whenever I travel somewhere with my wife, Christine, even if it’s for a weekend, she needs to check a bag. When I ask her why, she says, “A girl needs options,” hence the oversize luggage.
While it’s been easy for someone like my wife to have options, network engineers have never really had the same luxury. Network switches were typically built with fixed functionality, so an organization would need to purchase a wide range of equipment to meet all their needs.
Network professionals need greater flexibility from the network
Recently, the chip manufacturers have been building more programmable, flexible products. One of the examples of this is the Cavium XPliant processor that is the silicon that powers Arista’s 7160 switch. Another example is the Barefoot Networks Tofino processor. In addition to being one of the most scenic places on the planet, Tofino is a powerful system on a chip with a fully programmable parser and pipeline. The chip supports 256x 25 Gig-E Serializer/Deserializer (SerDes) at speeds of 1, 10, 25, 40, 50, and 100 Gig-E.
The terms software defined networking (SDN) and network functions virtualization (NFV) are often used interchangeably, which is incorrect. In a sense, the two are tied together as companies start using NFV as part of their SDN plans but that doesn’t have to be the case.
Enterprises could maintain their current network architecture and shift to NFV or they could roll out an SDN and never leverage the benefits of NFV, so it’s important to understand what each is and the benefits of both.
What is software-defined Networking
SDNs are a fundamentally different way to think about networks. Technically, SDNs can be defined as the separation of the management, control and data-forwarding planes of networks. Many people, including technical individuals read that definition and say, “So what?”, but the separation of these planes has a profound impact on networks and enables things that have never been done before.
