IDG Contributor Network: Visibility is key for devops and the hybrid cloud

Cloud has undoubtedly become a key component of successful business in recent years, especially when you consider the race to digitally transform. Across the globe, companies are moving their applications and services to the cloud and are consequently reaping the benefits of lower capex and opex as a result.However, with this process, cloud migration is only a beginning for any organization’s digital transformation (DX) journey. If harnessed correctly, cloud is a pillar of innovation for DX, and can be a driving force for new business models and use cases that – even a few years ago – weren’t possible. No one knows this better than devops teams; these teams hold the line when it comes to continuous delivery and deployment, and it therefore stands to reason that devops play a crucial role in the digital transformation journey. In practice however, the decision makers in charge of cloud strategies are rarely those in the bowels of the ship.To read this article in full, please click here

IDG Contributor Network: The rise of EVPN in the modern data center

Over the last few years, I have been sprawled in so many technologies that I have forgotten where my roots began in the world of data center. Therefore, I decided to delve deeper into what’s prevalent and headed straight to Ivan Pepelnjak EVPN webinar hosted by Dinesh Dutt.I knew of the distinguished Dinesh since he was the chief scientist at Cumulus Networks and for me; he is a leader in this field. Before reading his book on EVPN, I decided to give Dinesh a call to exchange our views about the beginning of EVPN. We talked about the practicalities and limitations of the data center. Here is an excerpt from our discussion.To read this article in full, please click here

IDG Contributor Network: Toto, I have a feeling we’re not in Kansas anymore

Welcome to Agility City! Let me set the scene: In the castle, the Wonderful Wizard orchestrates networks in beautiful and powerful ways. Point-to-point tunnel connections are heralded as “architectural wonders,” which decades ago were called bridges with disdain. Meanwhile, The Wicked Witch of the West brews a primordial potion of complexity that is hidden behind curtains of automated provisioning. Packets of information are heavily laden with unnecessary information and double encryption.It almost makes you want Dorothy Gale to appear and click her Ruby Red slippers; “There is no place like home. There is no place like home.” If only we start talking about true networking, and not orchestration of bridges.To read this article in full, please click here

Why Is The Universal Team Management Tool for Your Team

Every project management tool seeks to do the same instrumental thing: keep teams connected, on task and on deadline to get major initiatives done. But the market is getting pretty crowded, and for good reason — no platform seems to have gotten the right feel for what people need to see, and how that information should be displayed so that it’s both actionable/relevant, and contextualized. That’s why is worth a shot. The platform is based off a simple, but powerful idea: that as humans, we like to feel like we’re contributing to part of a greater/effort good — an idea that sometimes gets lost in the shuffle as we focus on the details of getting stuff done. So projects are put onto a task board (think of it like a digital whiteboard), where everyone can have the same level of visibility into anyone else who’s contributing set of tasks. That transparency breaks down the silos between teams that cause communication errors and costly project mistakes — and it’s a beautiful, simple way to connect people to the processes that drive forward big business initiatives.

What to expect when the Internet gets a big security upgrade

Ready or not, the upgrade to an important Internet security operation may soon be launched.  Then again, it might not.The Internet Corporation for Assigned Names and Numbers (ICANN) will meet the week of September 17 and will likely decide whether or not to give the go ahead on its multi-year project to upgrade the top pair of cryptographic keys used in the Domain Name System Security Extensions (DNSSEC) protocol – commonly known as the root zone key signing key (KSK) –  which secures the Internet's foundational servers.RELATED: Firewall face-off for the enterprise Changing these keys and making them stronger is an essential security step, in much the same way that regularly changing passwords is considered a practical habit by any Internet  user, ICANN says. The update will help prevent certain nefarious activities such as attackers taking control of a session and directing users to a site that for example might steal their personal information.To read this article in full, please click here

The correct levels of backup save time, bandwidth, space

One of the most basic things to understand in backup and recovery is the concept of backup levels and what they mean.Without a proper understanding of what they are and how they work, companies can adopt bad practices that range from wasted bandwidth and storage to actually missing important data on their backups. Understanding these concepts is also crucial when selecting new data-protection products or services.[ Check out 10 hot storage companies to watch. | Get regularly scheduled insights by signing up for Network World newsletters. ] Full backupTo read this article in full, please click here

Low-heat radios could replace cable links in data centers

Future 5G-based wireless networking equipment and data center equipment will combine antennas and the corresponding radio guts into one microprocessor unit, researchers from the Georgia Institute of Technology say.Integrating all of the wireless elements that one needs in a radio will reduce waste heat and allow better modulation, according to the group, which has been working on a one-chip, multiple transmitter and receiver package design. Longer transmission times and better data rates will result, they say.“Within the same channel bandwidth, the proposed transmitter can transmit six- to ten-times higher data rate,” says Hua Wang, an assistant professor in Georgia Tech's School of Electrical and Computer Engineering, in a news article on the university’s website about the idea.To read this article in full, please click here

Chip shrinking hits a wall: what it means for you

The semiconductor world is buzzing over the news that custom semiconductor manufacturer GlobalFoundries, the foundry born when AMD divested itself of its fabrication facilities, announced the sudden decision to drop its 7nm FinFET development program and restructure its R&D teams around “enhanced portfolio initiatives.”For now, GlobalFoundries will stick to 12nm and 14nm manufacturing. All told, approximately 5 percent (of roughly 18,000 employees) will lose their jobs. But it also sets back AMD, a GlobalFoundries customer, in its bid to get ahead of Intel, which has struggled for two years to get to 10nm and won’t get there until 2020.[ Learn who's developing quantum computers. ] “The vast majority of today’s fabless customers are looking to get more value out of each technology generation to leverage the substantial investments required to design into each technology node. Essentially, these nodes are transitioning to design platforms serving multiple waves of applications, giving each node greater longevity. This industry dynamic has resulted in fewer fabless clients designing into the outer limits of Moore’s Law,” said Thomas Caulfield, who was named CEO of GlobalFoundries last March, in a statement.To read this article in full, please click here

Linux kernel 4.18: Better security, leaner code

The recent release of Linux kernel 4.18 followed closely by the releases of 4.18.1, 4.18.2, 4.18.3, 4.18.4, and 4.18.5 brings some important changes to the Linux landscape along with a boatload of tweaks, fixes, and improvements.While many of the more significant changes might knock the socks off developers who have been aiming at these advancements for quite some time, the bulk of them are likely to go unnoticed by the broad expanse of Linux users. Here we take a look at some of the things this new kernel brings to our systems that might just make your something-to-get-a-little-excited-about list.[ Also read: Invaluable tips and tricks for troubleshooting Linux ] Code Cleanup For one thing, the 4.18 kernel has brought about the surprising removal of nearly 100,000 lines of outdated code. That's a lot of code! Does this mean that any of your favorite features may have been ripped out? That is not very likely. This code cleanup does means that a lot of code deadwood has been carefully expunged from the kernel along with one significant chunk. As a result, the new kernel should take up less memory, Continue reading

Microsoft lures Win Server 2008 users toward Azure

Microsoft is offering extended support for Windows Server 2008 and SQL Server 2008 to customers who shift these platforms from on-premises into Microsoft’s Azure cloud.The scheduled ends of extended support for the 2008 versions of Server and SQL Server are Jan. 14, 2020 and July 9, 2019, respectively. But if customers move these workloads into the Azure cloud, they get three extra years of support at no extra cost beyond the price of the Azure service.In the past, when the end-of-life clock started ticking, organizations made a mad dash to upgrade operating systems and SQL servers in order to keep their systems supported. Some organizations chose to continue running their applications completely unsupported, unpatched and un-updated – a very bad thing to do in this age of viruses, malware and cyberattacks.To read this article in full, please click here

Is the Linux 4.18 kernel heading your way?

How soon the 4.18 kernel lands on your system or network depends a lot on which Linux distributions you use. It may be heading your way or you may already be using it.If you have ever wondered whether the same kernel is used in all Linux distributions, the answer is that all Linux distributions use the same kernel more or less but there are several big considerations that make that "more or less" quite significant. Most distributions add or remove code to make the kernel work best for them. Some of these changes might eventually work their way back to the top of the code heap where they will be merged into the mainstream, but they'll make the distribution's kernel unique -- at least for a while. Some releases intentionally hold back and don't use the very latest version of the kernel in order to ensure a more predictable and stable environment. This is particularly true of versions that are targeted for commercial distribution. For example, RHEL (Red Hat Enterprise Edition) will not be nearly as aggressively updated as Fedora. Some distributions use a fork called Linux-libre, which is Linux without any proprietary drivers built in. It omits software Continue reading

Excess data center heat is no longer a bug — it’s a feature!

Every data center admin knows that dealing with excess heat is one of the biggest, most expensive factors involved in running a modern data center.For decades, engineers have been looking for new ways to mitigate the issue, and now Norway is building a brand-new town designed to turn the problem into an opportunity to lower costs, reduce energy usage, and fight climate change.[ Read also: Data center cooling market set to explode in the coming years | Get regularly scheduled insights: Sign up for Network World newsletters ] Hug your servers ... to stay warm According to Fast Company, the town of Lyseparken, now under construction near Bergen, Norway, is being built to use the excess heat generated by a new data center in the heart of the community to keep a nearly 6.5 million square feet of nearby planned business and office space—and eventually up to 5,000 homes—warm.

Will Fujitsu be the first to make an ARM-powered supercomputer?

I’ve long felt Japan has been severely overlooked in recent years due to two “lost decades” and China overshadowing it — and supercomputing is no exception.In 2011, Fujitsu launched the K computer at the Riken Advanced Institute for Computational Science campus in Kobe, Japan. Calling it a computer really is a misnomer, though, as is the case in any supercomputer these days. When I think “computer,” I think of the 3-foot-tall black tower a few feet from me making the room warm. In the case of K, it’s rows and rows of cabinets stuffed with rack-mounted servers in a space the size of a basketball court.With its distributed memory architecture, K had 88,128 eight-core SPARC64 VIIIfx processors in 864 cabinets. Fujitsu was a licensee of Sun Microsystems’ SPARC processor (later Oracle) and did some impressive work on the processor on its own. When it launched in 2011, the K was ranked the world's fastest supercomputer on the TOP500 supercomputer list, at a computation speed of over 8 petaflops. It has since been surpassed by supercomputers from the U.S. and China.To read this article in full, please click here

IDG Contributor Network: Analytics are the key to network uptime, but are they enough?

Imagine you are in a crowded ER, and doctors are running from room to room. In the waiting area, patients are checking in via an online portal, and hospital staff are quickly capturing their confidential medical and insurance information on a mobile device. You look down the hall, where admitted patients are receiving treatment through Wi-Fi enabled biomedical devices, and some are even streaming their favorite show on Netflix while they wait. In a hospital, there are hundreds of individuals conducting critical tasks at any given moment, and they rely on thousands of connected devices to get the job done. But, this begs the question: What happens if that network fails?To read this article in full, please click here
