Interested in Virtualization? Check Out Our Newest Addition to the INE Library: Virtualization – Introduction to Hypervisor (KVM)

Virtualization is a key skillset for any Linux Administrator or Engineer. Not all workloads are useful in the cloud, and companies are quickly realizing this in terms of increasing cloud bills. You can bring those workloads in house, but what about licensing? KVM is a favorite of home labs because of the low cost of entry (free). KVM is also a favorite of shops that know how powerful open source is. Gain a greater understanding of how any virtualization platform works by utilizing common linux tools to manage and orchestrate your virtual machines. KVM forms the basis for upstream virtualization projects like oVirt and RHEV as well. Learn how to setup a virtualized environment only armed with an install usb from your favorite linux distribution.

 

Any workload can be run on a KVM virtual machine platform. Docker/Kubernetes? No problem. Databases, front end web services, workloads requiring dedicated hardware such as GPU’s or HBA’s, KVM can run any of these workloads with near bare metal performance.

What You’ll Learn:

• Setting up the hypervisor machine
• Installing your first virtual machine
• managing network storage memory and cpu resources
• Virtual machine snapshots
  Virtual machine cloning

BrandPost: What We Can Learn from IT in Education

Among the vertical industries most impacted by technological change in the past three to five years is K-12 education. This is often overlooked, but the move to becoming digital is truly changing the game for school districts. Changes wrought by extensive device use, distance learning, and emerging technologies such as virtual reality and augmented reality require that K-12 schools dramatically overhaul their approach to IT. In many ways, the IT need at schools has similar or greater demands for availability, reliability, and scalability to support new applications than what is seen in other industries. However, the rapid rate of change that has occurred in K-12 is exceptional. There are some important lessons that we can learn from the “high speed” that IT professionals and administrators are responding to.To read this article in full, please click here

IDG Contributor Network: Cisco Digital Network Architecture: a prison of promises or the next big thing?

Cisco’s Digital Network Architecture (DNA) promises to help companies in their digital transformation journey where new technologies can be used to accelerate business activities and processes to make them more competitive. It's also a big validation that network analytics is no longer a nice to have but a must have. Cisco DNA aims to provide a platform that companies can use as the foundation for digital transformation projects. The architecture's key tenants are virtualization, automation, analytics, a cloud-based service management layer, and open application programming interfaces (APIs). It’s a system that’s “designed for automation.” In other words, Cisco wants to make its products easier to deploy and manage. At the heart of that message is a move away from CLI. Sounds good so far.To read this article in full, please click here

On the Web: Openfabric at IPspace

I was over at ipspace to talk to Ivan and several other folks about openfabric. This is one of those situations where… Well, the algorithm openfabric uses to calculate fabric location has changed slightly in the last week. Welcome to the world of networking technology.

As always, we started with the “what’s wrong with what we have right now, like using BGP as a better IGP” question, resulting in “BGP is becoming the trash can of the Internet”. You can probably guess the next set of intro questions: “Do we need policies and traffic engineering in a high-speed data center fabric?” Finally, we got to discussing OpenFabric, starting with how OpenFabric uses link-state database to modify IS-IS flooding behavior and thus reduces the total amount of flooding in a data center fabric. Next step: how do you know where it’s safe to reduce flooding? You have to figure out whether you’re a leaf or spine, and there are two ways in OpenFabric to solve that challenge.

IDG Contributor Network: Improving supply chains with the IoT and blockchain

The U.S. Centers for Disease Control and Prevention recently advised "consumers to throw away any store-bought romaine lettuce and warned restaurants not to serve it amid an E. coli outbreak that has sickened more than 50 people in several states."This problem highlights the dangers of modern supply chains. They help lower costs and improve business efficiency, but they’re complex and a single failure can sicken people thousands of miles away. The food we eat and the medicines we use come from remote suppliers, transported in refrigerated trucks, and stored in different warehouses. How can perishable commodities be tracked from suppliers to customers? How can the temperature conditions during shipment be monitored to avoid contamination? How can spoilt products be quickly recalled even if they’re in transit or stored in a warehouse?To read this article in full, please click here

Deconstructing the Encryption Debate: The Internet Society-Chatham House Roundtable on Encryption and Lawful Access Report

Encryption is an important technical building block for Internet trust. It secures our infrastructure, enables e-commerce, ensures the confidentiality of our data and communications, and much more. Yet, because bad actors can also use encryption to hide their activities, it can present challenges for law enforcement.

How, or even if, law enforcement should gain access to encrypted content has remained a divisive issue for the last twenty years. Yet, even as encryption tools have grown in variety and use, the public debate has become over-simplified into a battle between those for and against encryption. That public debate often fails to address the nuances of the digital-communications and data-storage landscape, or how it has evolved. With both sides largely talking at each other, rather than listening to one another, there has been little headway towards a solution, or set of solutions, that is acceptable to all.

In October of 2017, the Internet Society and Chatham House convened an experts roundtable under the Chatham House Rule to deconstruct the encryption debate. They explored ways to bridge two important societal objectives: the security of infrastructure, devices, data, and communications; and the needs of law enforcement. The roundtable brought together a diverse set of Continue reading

BrandPost: Making Intelligent Network Automation a Reality with Advanced Analytics

Today’s digital economy depends entirely on the speed and reliability of the networks across which information flows. And while it has become cliché to say the demands on the network are increasing, the facts bear this out: the number of Internet of Things (IoT) connected devices is set to triple—to 27 billion devices—over the next 10 years. Cellular connections will grow even more over the same period, by 85 percent to 2.2 billion, according to a recent study by Machina Research.1The way customers use the network is also changing. The rise in popularity of cloud services is growing by double digits every year, including Infrastructure as a Service (IaaS) and Software as a Service (SaaS), which Gartner predicts will grow by 36.8 and 20.1 percent, respectively, this year alone. Users expect to be able to access these cloud services on any device, from any location and at any time, which places greater demand on the network both in terms of traffic volume as well as increased performance and reliability requirements.To read this article in full, please click here

How to share files between Linux and Windows

Many people today work on mixed networks, with both Linux and Windows systems playing important roles. Sharing files between the two can be critical at times and is surprisingly easy with the right tools. With fairly little effort, you can copy files from Windows to Linux or Linux to Windows. In this post, we'll look at what is needed to configure your Linux and Windows system to allow you to easily move files from one OS to the other.Copying files between Linux and Windows The first step toward moving files between Windows and Linux is to download and install a tool such as PuTTY's pscp. You can get PuTTY from putty.org and set it up on your Windows system easily. PuTTY comes with a terminal emulator (putty) as well as tools like pscp for securely copying files between Linux and Windows systems. When you go to the PuTTY site, you can elect to install all of the tools or pick just the ones you want to use by choosing either the installer or the individual .exe files.To read this article in full, please click here

CCIE Datacenter Updated to Version 2.1

Last year Cisco announced that they would revise their certifications more often and in smaller increments instead of doing only major revisions which had problems keeping up with the pace of the industry.

This is exactly what they are now doing to the CCIE Datacenter certification which is being updated from version 2.0 to 2.1.

The full list of changes can be seen in this link.

Some highlights of the change below:

• FabricPath is being removed
• ACI multipod and multi-site added
• Intersight is being added
• CloudCenter is being added
• vPath is being removed
• RISE is being removed
• UCS Central is being removed

It is clear that ACI and cloud are important going forward and some older technologies had to be removed to make room for the new additions. Seems like a good updated to me. I’m happy to see these minor revisions coming in instead of the major ones which usually only took place every four years or so.
