BrandPost: Customers will see many upsides to new SD-WAN services & features

The early days of offering a managed SD-WAN service that provides basic network connectivity are drawing to a close. There is clearly burgeoning demand from customers to manage the network providers and network types that make up the growing mix of SD-WAN bandwidth options.As customers see the value of having different network providers and networks to improve reliability and overall cost per megabit for bandwidth, service providers increasingly will be needed to manage those networks and providers. This is one of the basic tenets for revenue opportunities from SD-WAN services. And with many providers, those revenue opportunities may include the use of wholesale agreements to improve the margin of network services along with the revenue inherent in managing multiple providers for customers.To read this article in full, please click here

IDG Contributor Network: The top 5 user requirements of IoT edge platforms

As an IoT platform and middleware analyst, I am asked constantly about the benefits of IoT platforms and “what makes a great IoT platform.” In response, I often ask these curious inquirers if they’ve ever used IoT platforms themselves. Walking on the edge is exhilarating, but having hands-on insights, data and expertise on how to survive the journey is even better.What do users actually experience when they use IoT edge platforms?IoT edge computing is a technology architecture that brings certain computational and analytics capabilities near the point of data generation. IoT edge platforms provide the management capabilities required to deliver data from IoT devices to applications while ensuring that devices are properly managed over their lifetimes. Enterprises use edge platforms for factory automation, warehousing/logistics, connected retail, connected mining and many other solutions. With IoT platform revenue slated to grow to USD63.4 billion by 2026, IoT edge is one of the most highly relied upon enterprise IoT platform approaches. To read this article in full, please click here

IDG Contributor Network: What the storage industry’s inevitable transition to the cloud means for your business

Just a few weeks ago, Microsoft made a relatively unheralded acquisition of a company named Avere Systems. Avere’s raison d’etre is enterprise storage. In their own words, “Avere Systems was created by file systems experts determined to reinvent storage by changing the way enterprises thought about and bought storage resources.” Ostensibly, Microsoft purchased this firm to add cloud-based storage capabilities to its ever-expanding portfolio.To read this article in full, please click here

IDG Contributor Network: 6 steps to engage and manage a vendor who isn’t meeting your standards

During the sales process, every vendor sounds great. They have case studies, they have great-looking material, they talk like experts and everything is good. But nothing is as simple as it looks in the beginning.There are always additional challenges. The true test of a service provider, or any vendor, is how they respond to those changes and challenges. Do they put you, the customer, first or do they get slow and unresponsive? If you have a vendor who isn’t meeting your needs, but you’re locked into a contract that makes it cost-prohibitive to leave, these steps will help you reduce some of the friction in the relationship, while providing a better outcome for your company.To read this article in full, please click here

Configuration errors in Intel workstations being labeled a security hole

Security researchers at an antivirus company have documented another potentially serious security hole in an Intel product, this time in the mechanism for performing system updates. The good news, however, is that it is limited to desktops, is a configuration error, and does not appear to impact servers.Last June, researchers at F-Secure found a flaw in Intel’s Active Management Technology (AMT), a feature used to perform remote updates to advanced desktops using Intel vPro or workstation platforms using Core desktop chips and certain Xeon CPUs. Xeon is primarily a server processor but there are some low-end chips used in high-performance workstations, such as those used in a CAD environment.To read this article in full, please click here

IoT security needs a white knight

Thanks to the Mirai botnet attacks, few people in the world of tech need a reminder that IoT devices remain a serious threat to enterprise networks. Still, more than a year after the botnet made headlines worldwide, IoT security remains mostly an idea, rather than a reality.Such is the scope of the problem that Frost and Sullivan IoT research director Dilip Sarangan argues for governmental intervention. Sarangan says that, because the responsibility for IoT security is diffused across device manufacturers, network providers, software developers and many others, it’s difficult for the industry to make progress on all-encompassing standards.To read this article in full, please click here

Facebook and Amazon are causing a memory shortage

If you’ve noticed a considerable increase in the price of memory in the last few months, you can thank (or blame) Amazon, Facebook, and Google. The explosion in growth among hyperscale data centers is great if you are a supplier of components to these companies, not so great if you are buying those same components.According to DRAMeXchange, a division of market researcher TrendForce, the price of server DRAM will continue to rise as the supply remains tight in the first quarter of this year. The server DRAM market has seen tight supply since the third quarter of last year due to massive construction projects by the data center market, especially the hyperscale data centers, data centers that are bigger than a football field.To read this article in full, please click here

Wi-Fi Alliance announces WPA3 to secure modern networks

The Consumer Electronics Show (CES) is an odd place to announce an enterprise product, but the Wi-Fi Alliance used the massive trade show — which has more or less taken over where Comdex left off — to announce a major upgrade to Wi-Fi security.The alliance announced the Wi-Fi Protected Access 3 (WPA3), a new standard of Wi-Fi security that greatly increases the security capabilities of the wireless standard. WPA2, which is the current standard in wireless security, has been around for 14 years, so this is way overdue.To read this article in full, please click here

2018 state of resilience: The pressure is on

As we swerve onto the runway in 2018, IT leaders are finding themselves under increased pressure to ensure security, high availability and disaster recovery for the applications and systems under their care. The results of several surveys underscore the concerns of nearly 6,000 IT professionals around the globe.These surveys, conducted in 2017 by Vision Solutions, now part of Syncsort, collected responses from 5,632 professionals to determine their key business continuity concerns and their strategies for addressing high-profile hacking attacks, data breaches, disruptive natural disasters, and escalating storage and data accessibility needs. The results highlight their areas of greatest concern and the key initiatives they are putting into place for moving forward.To read this article in full, please click here

IDG Contributor Network: Will China start blocking SD-WAN traffic…today?

More than a decade ago, I launched the forerunner to SD-WAN Experts, MPLS Experts, on a project to China. Back then finding out telecom services in another country, let alone another continent, seemed like a mission impossible. China was among the most difficult.Much has changed in our industry. MPLS has given way to SD-WAN, but some things remain the same. We still need global connectivity and China continues to remain a mystery. My story about China blocking VPN traffic – and potentially SD-WAN traffic – caused quite a stir in the industry, in large part because, like so many things when dealing with China, concrete information remains scarce (particularly for non-native speakers).To read this article in full, please click here

IDG Contributor Network: 5 things analytics could tell you about your network in 2018

1. Whether your users are happy (without having to talk to them) It’s not always cool to admit, but the ultimate goal of every networker is to have happy users. Like many other thankless jobs, we only hear about problems. When we do, we react. But that isn’t ideal. What we really want is to know about problems as they are developing, before users complain. They don't even have to know.  But we do.A Network Management System (NMS) has been the traditional go-to solution to sniff out these sorts of problems. But most were designed for just one view of a certain part of the network using antiquated technology that doesn't provide any sort of predictive problem solving based on what the user is actually experiencing. It's like trying to figure out San Francisco traffic based on the status of the traffic signals. Just because the signals are working properly doesn’t mean the drivers (users) are having a good experience.To read this article in full, please click here

How Cisco’s newest security tool can detect malware in encrypted traffic

Cisco’s Encrypted Traffic Analytics (ETA), a software platform that monitors network packet metadata to detect malicious traffic, even if its encrypted, is now generally available.The company initially launched ETA in June, 2017 during the launch of its intent-based network strategy and it’s been in a private preview since then. Today Cisco rolled ETA out beyond just the enterprises switches it was originally designed for and made it available on current and previous generation data center network hardware too.+MORE AT NETWORK WORLD: What is intent based networking? | Why intent based networking could be a big deal +To read this article in full, please click here

Is Cisco’s Mobility Express right for you?

One of the hottest topics on the minds of our customers for 2018 continues to be their wireless infrastructure. As WLAN 802.11ac wave 2 devices becoming mainstream, Cisco has placed a stake in the ground claiming to be the “value leader.”Cisco's solution to accomplish this is Mobility Express, designed to help companies easily set up wireless LAN (WLAN) networks. What exactly is Mobility Express? And is it right for you?What is Mobility Express? Mobility Express is the ability to use an access point (AP) as a controller. That means a lightweight network without a controller box. Instead one of the APs on the network acts as the controller.

Hyperconverged secondary storage market heats up

There’s no question that the hyperconverged infrastructure (HCI) has had a huge impact on simplifying technology deployments. Nutantix solutions, Cisco HyperFlex and HPE Simplivity have been widely adopted and have changed the face of the data center.HCI was initially considered niche to simplify the deployment of virtual desktop infrastructure (VDI), but it has seen increased adoption for other workloads. One use case for HCI that has flown under the radar is secondary storage. Late last year, I profiled Cohesity, the vendor that has been leading the emerging hyperconverged secondary storage market.To read this article in full, please click here

IDG Contributor Network: How network verification differs from monitoring, and what it’s good for

In a previous post I discussed network verification, a new area of technology that applies what is known as formal verification – mathematical analysis of a complex system to determine rigorously if it meets the end-to-end goal – to network infrastructure.But what is such verification good for and how is it different from today’s common practice, whereby nearly every organization monitors its network, typically by sampling ongoing flows, events or logs. Isn’t that enough to catch problems as the organization deploys changes?To read this article in full, please click here
