What to do if your cloud provider stops offering its services

What would your organization do if your cloud provider were to go out of business? What happens if your cloud provider suddenly stops offering critical services that your organization requires for its business to function properly? Businesses need to start asking these important questions and develop plans to address these scenarios.The cloud is a new market that continues to grow, and there are more small players offering their services. According to Gartner, Cloud System Infrastructure Services (IaaS) are expected to grow from $45.8 billion in revenue in 2018 to $72.4 billion in 2020. As the market matures, it's only natural that some of these organizations will disappear or stop offering certain services. In 2013, Nirvanix stopped offering it cloud services and gave customers only two weeks’ notice to move their data off of their platform.To read this article in full, please click here

Another selling point of bare-metal cloud providers: local service

Several things make bare-metal cloud providers appealing compared with traditional cloud providers, which operate in a virtualized environment. Bare-metal providers give users more control, more access to hardware, more performance, and the ability to pick their own operating environment.There's another interesting angle, as articulated by Martin Blythe, a research fellow with Gartner. He maintains that bare-metal providers appeal to small and mid-sized businesses (SMBs) because those companies are often small, local players, and SMBs looking for something more economical than hosting their own data center often want to keep the data center nearby.To read this article in full, please click here

Future wireless networks will have no capacity limits

In what may turn out to be a precursor to the demise of wired connections, a scientist claims that ultimately, wireless networks won’t have a capacity ceiling.Researchers have generally thought there was a maximum to the amount of data that could be sent within certain bandwidths, spaces and over a period, even using the best antennas. However, massive multiple input, multiple output (MIMO) antennas will provide for unlimited and thus vast streams of data to be communicated over the airwaves, says Emil Björnson and his fellow researchers at Swedish Linköping University. He says his group has discovered that capacity limit calculations used for the new antennas, expected to be used widely in 5G, are wrong.To read this article in full, please click here

Predictive maintenance: One of the industrial IoT’s big draws

One subset of the internet of things – the industrial IoT – adds new capabilities to operational technology including remote management and operational analytics, but the number-one value-add so far has been predictive maintenance.Combining machine learning and artificial intelligence (AI) with the deep pool of data generated by the flood of newly connected devices offers the opportunity to more deeply understand the way complex systems work and interact with each other.RELATED: Tips for security IoT on your network Most powerful IoT companies The internet of useful things - in pictures And that can promote predictive maintenance - with the ability to pinoint when components of industrial equipment are likely to fail so they can be replaced or repaired before they do, thereby avoiding more costly damage and downtime.To read this article in full, please click here

13 flaws found in AMD processors, AMD given little warning

It’s probably a good thing AMD didn’t rub Intel’s nose in the Meltdown and Spectre flaws too much because boy, would it have a doosy of a payback coming to it. A security firm in Israel has found 13 critical vulnerabilities spread across four separate classes that affect AMD’s hot new Ryzen desktop and Epyc server processors.However, the handling of the disclosure is getting a lot of attention, and none of it good. The company, CTS-Labs of Israel, gave AMD just 24 hours notice of its plans to disclose the vulnerabilities. Typically companies get 90 days to get their arms around a problem, and Google, which unearthed Meltdown, gave Intel six months.To read this article in full, please click here

BrandPost: From Autonomous to Adaptive: The Next Evolution in Networking

There have been many discussions about how to eliminate manual, labor-intensive network operations and the industry is using a wide set of terminology to describe the future lean and automated network operations, such as ‘intelligent’, ‘cognitive’ or ‘self-driving.’ Network providers are now able to rethink their operations with artificial intelligence (AI) and advanced analytics to achieve their long-desired goal of end-to-end automation, but most of them don’t want to cede control to networks that decide their own direction and remove humans from the equation altogether. They want their networks and operations to become more ‘adaptive’ to thrive in an ever-changing competitive landscape and to meet consumer demands, which requires a coherent combination of human-controlled-and-supervised, analytics-driven intelligence, software controlled and automated operational processes and an underlying programmable infrastructure (see Figure 1).To read this article in full, please click here

BrandPost: What is the Adaptive Network?

Since the introduction of the first Public Switched Telephone Network, networks have continually evolved. Through the various stages of development—from fixed endpoints in the early Internet to today’s broadband networks that connect mobile users to massive data centers and bandwidth behemoths like Netflix, Amazon, and Facebook—networks have adjusted to accommodate new demands.The once-static infrastructure is undergoing a more profound transformation than ever before. The latest incarnation is autonomous networking, which is a trend that has been building for some time. The autonomous network runs without much human intervention. It can configure, monitor and maintain itself independently.To read this article in full, please click here

If you read my Valentine’s Day post, you know I love intent-based networks (IBN), as the technology is the biggest change in networking in decades.Cisco wasn’t the first vendor to offer an IBN solution, but they’ve certainly been the most vocal about the need and has been the network industry's biggest evangelist. Also read: Getting grounded in intent-based networking The value proposition of IBN is to simplify networking dramatically with the long-term vision of having a fully autonomous network. With IBN, the operations of the network are driven by business intent to ensure policies are adhered to and application performance remains optimized.To read this article in full, please click here

BrandPost: What Is Programmable infrastructure?

In an increasingly mobile world, network providers are grappling with a data explosion. Millions of mobile users are running video and other applications that require significant bandwidth.At the same time, those providers are saddled with legacy systems and protocols that leave them bloated and slow. Even to add simple services, they have to contend with hundreds of manual processes for set up, revisions, and tear down of even the simplest services.With challenges like that, anticipating and responding to dynamic traffic levels and service requests is nearly impossible. These legacy networks simply cannot handle the growing and unpredictable demands on providers, and the problem is only going to worsen.To read this article in full, please click here

New Spectre derivative bug haunts Intel processors

Intel just can’t catch a break these days. Researchers at Ohio State University have found a way to use the Spectre design flaw to break into the SGX secure environment of an Intel CPU to steal information.SGX stands for Software Guard eXtensions. It was first introduced in 2014 and is a mechanism that allows applications to put a ring around sections of memory that blocks other programs, the operating system, or even a hypervisor from accessing it.To read this article in full, please click here

BrandPost: What Is Intelligent Automation?

The operations environment for service providers is growing increasingly complex. While advancements like Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) enable on-demand services, among many other benefits, existing network management and Operational Support Systems (OSSs) lack the scale and flexibility to meet the requirements of these more dynamic network technologies.Simple automation techniques like custom scripting are often used to reduce repetitive manual tasks, but providers are looking for more robust automation capabilities to reduce operational complexity and improve efficiency, at scale. By leveraging software purpose-built for dynamic SDN/NFV environments, and incorporating recent advancements in big data analytics and machine learning, network operators can make true intelligent automation possible from end-to-end and, as a result, run their businesses smarter and much more efficiently.
