Why a bare-metal cloud provider might be just what you need

Cloud services, particularly infrastructure- and platform-as-a-service, are well established, but in some cases customers demand more – more control, more access to hardware, more performance, and the ability to pick their own operating environment.In those cases they are looking to bare-metal servcies, a niche that is growing fast.As the name implies, bare metal means no software just CPUs, memory, and storage. Customers provide all of the software from the operating system on up. That means a dedicated CPU, full access to the hardware, and freedom to run custom operating systems.According to a 2016 Markets and Markets report, the bare metal cloud market is expected to grow from $871.8 million in 2016 to $4.7 billion in 2021, at an estimated compound annual growth rate of 40.1%.To read this article in full, please click here

EdgeMicro announces 30-city edge-network deployment

There is quite a rush on to build out edge computing networks, that vital link between the massive amount of Internet of Things (IoT) devices and data centers. One of the companies involved is newcomer EdgeMicro, which announced plans to deploy micro-data centers in 30 cities around the U.S. for an unnamed cellular partner.EdgeMicro said “a leading North American mobile network operator” has begun verification tests of its technology. It did not name the operator, but if it’s a national operator covering 30 major cities, there are only four obvious candidates — Verizon Wireless, AT&T, Sprint, or T-Mobile.To read this article in full, please click here

IDG Contributor Network: Submarine cable boom fueled by new tech, soaring demand

It’s been 160 years since the world’s first submarine cable linked a remote corner of Trinity Bay, Newfoundland, with Valentia Island on the west coast of Ireland in 1858. That telegraph cable failed after three weeks, but a new method for transoceanic communications had been established, and today submarine cables are a critical piece of digital infrastructure that’s fast expanding in prevalence and prominence globally – though not yet quickly enough to meet voracious demand for capacity.Between 2013 and 2017, the subsea cable industry has added an average of 32 percent of capacity annually on major submarine cable routes, according to the industry magazine SubTel Forum. Still, the industry needs to do more. “It will have to increase activity to stay ahead of demand,” SubTel Forum said in its annual report this year.To read this article in full, please click here

Super Bowl LII set football and Wi-Fi network records

Super Bowl LII was played about a month ago, and much to the chagrin of New England Patriots fans, the team lost despite a number of records being set by Tom Brady and his team. In a losing effort, the QB threw for over 500 yards, something that had never been done before. Also, no losing team has ever had as many yards or points. It was certainly one of the most memorable games in recent history, particularly for the long-suffering Philadelphia Eagles fans.Records were also set in the stands with new highs in Wi-Fi network usage. For the fifth consecutive year, Extreme Networks was the Official WiFi Analytics provider of the Super Bowl, and its ExtremeAnalytics (formerly known as Purview) captured all the data transferred over the stadium Wi-Fi network. (Note: Extreme is a client of ZK Research.) The NFL and its individual teams have been using the data to better understand what fans do on their mobile devices during games in hopes of creating an overall better experience. Some of the highlights from the big game are listed below.To read this article in full, please click here

What is 802.11ax Wi-Fi, and what will it mean for 802.11ac

Each new Wi-Fi standard has brought significant improvements in performance, with the most recent, 802.11ac, offering an impressive theoretical maximum rate of 1.3Gbps.  Unfortunately, these gains have not been enough to keep pace with demand, leading to that exasperated cry heard across airports, malls, hotels, stadiums, homes and offices: “Why is the wireless so slow?”The IEEE is taking another crack at boosting Wi-Fi performance with a new standard called 802.11ax or High-Efficiency Wireless, which promises a fourfold increase in average throughput per user.RELATED: Can MU-MIMO really boost wireless capacity? 802.11: Wi-Fi standards and speeds explained Wi-Fi 2018: What does the future look like? 802.11ax is designed specifically for high-density public environments, like trains, stadiums and airports. But it also will be beneficial in Internet of Things (IoT) deployments, in heavy-usage homes, in apartment buildings and in offices that use bandwidth-hogging applications like videoconferencing.To read this article in full, please click here

IDG Contributor Network: What does SD-Branch mean for security, storage and IoT?

We’ve started to hear a lot about SD-Branch as a natural successor to SD-WAN, which makes sense as the centrally-orchestrated model is attractive to many enterprises. However, just as we saw with SD-WAN, the term “SD-Branch” is being adopted by many different vendors and service providers to mean what they want, in the absence of any “official” definition.What is SD-Branch anyway? Based on most definitions, SD-Branch means delivering more IT infrastructure to branches under a programmable, centrally orchestrated model. Think of it as “SD-WAN plus” – just as you can create templates or profiles in an SD-WAN network, an entire branch template could be generated that defines how the LAN is configured, what wireless LANs are used, how they integrate with the WAN, and what additional compute-based services need to be deployed at the branch.To read this article in full, please click here

IDG Contributor Network: If applications speak in sessions, shouldn’t your router be session smart?

My new iPhone X actually recognizes me! This is an example of Smart Technology.Most of us are expecting a revolution of products and services that have embedded intelligence or smarts. Medical diagnostic support is being aided by computer intelligence with the goal to improve the physician’s understanding of the patient to improve the diagnosis, therapies and resulting patient outcomes without adding more burden on the clinician. Look at cars – now, autonomous self-driving vehicles have the potential to alleviate congestion and improve the environment in ways we couldn’t imagine.To perform facial recognition, the iPhone X must understand the language of faces. This includes attributes of faces, such as shape of eyes, noses, cheekbones, and jaw. It’s safe to say that any smart system needs to understand the language of its purpose. Self-driving cars must understand the language of driving which includes maps, roads, signs, speed limits, weather, and traffic signals. Smart medical diagnostics need to understand the language of medicine, including possible diagnosis and probabilities.To read this article in full, please click here

IDG Contributor Network: The massive role of tiny antennas

The Shannon-Hartley theorem expresses “the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise.”Translation: wireless data can only travel so fast. But if data rates are finite, how can we support the rollout of Gigabit LTE, and one billion new 5G connections by 2025?Over the next few years, wireless connections will become ubiquitous – not only in our phones, tablets and PCs – but in our home, car and cities, thanks to an unglamorous and often-forgotten RF enabler: the antenna. Far from the laughably chunky antennas of early mobile phones, today’s nearly-invisible antenna systems make high-speed networking possible. They’re evolving as new wireless technologies emerge to satisfy our demand for content on the move.To read this article in full, please click here

Juniper’s new products help prepare networks for hybrid, multi-cloud

Earlier this week, Juniper Networks announced a bevvy of new networking products. (Note: Juniper Networks is a client of ZK Research.) In his blog post about the products, Andy Patrizio did an effective job covering the basics of the news. But left out some important points, and I wanted to make sure those got called out, including Juniper's tagline “multi-cloud ready."  Hybrid, multi-cloud is inevitable  As I’ve pointed out in many of my posts, hybrid multi-cloud environments are inevitable for most organizations. Small businesses may be able to build an IT strategy that is all public cloud, but any large company is going to choose a mix of private and public clouds.To read this article in full, please click here
