What is hyperconvergence?

Hyperconvergence is an IT framework that combines storage, computing and networking into a single system in an effort to reduce data center complexity and increase scalability.Hyperconverged platforms include a hypervisor for virtualized computing, software-defined storage, and virtualized networking. They typically run on standard, off-the-shelf servers and multiple nodes can be clustered to create pools of shared compute and storage resources, designed for convenient consumption.The use of commodity hardware, supported by a single vendor, yields an infrastructure that's designed to be more flexible and simpler to manage than traditional enterprise storage infrastructure. For IT leaders who are embarking on data center modernization projects, hyperconvergence can provide the agility of public cloud infrastructure without relinquishing control of hardware on their own premises.To read this article in full, please click here

Get TotalAV Essential AntiVirus for $19.99 (80% off)

The term “computer virus” calls to mind imagery of pathogenic creepy-crawlies bringing down a device’s operating system, their flagella wriggling as they multiply into hordes that infiltrate its chips and wires. And while it’s true that our computers can be infected with literal biological bacteria like staphylococci, per Science Illustrated, the threat of malicious codes and programs intent on corrupting data and files looms far larger: According to a recent study from the University of Maryland’s Clark School of Engineering, attacks on computers with internet access is virtually ceaseless, with an incident occurring every 39 seconds on average, affecting a third of Americans every year.

Ansible Operator: What is it? Why it Matters? What can you do with it?

Blog-Ansible-and-Openshift

The Red Hat Ansible Automation and Red Hat OpenShift teams have been collaborating to build a new way to package, deploy, and maintain Kubernetes native applications: Ansible Operator. Given the interest in moving workloads to Kubernetes, we are happy to introduce a new tool that can help ease the move toward cloud native infrastructure.

What is Kubernetes? The simplest definition of Kubernetes I’ve ever used is, “Kubernetes is a container orchestrator.” But that is a simplified definition.

What is OpenShift? Red Hat OpenShift Container Platform is an enterprise-grade Kubernetes distribution. It enables management of container applications across hybrid cloud and multicloud infrastructure.

First, let’s identify the problem operators can help us solve. Operators help simplify deployment, management, and operations of stateful applications in Kubernetes. But, writing an operator today can be difficult because of the knowledge of Kubernetes components required to do so. The Operator SDK is a framework that uses the controller-runtime library to help make writing operators more simple. The SDK enables Operator development in Go, Helm, or Ansible.

Why It Matters

What can an Ansible Operator give us that a generic operator doesn’t? The same things Ansible can give its users: a lower barrier to entry, faster iterations, Continue reading

The IPv6 Problem is IPv4

At the end of the day, most engineers want to implement IPv6 because they know, deep down, that it is an eventual necessity.  One problem is that no one is talking about quitting IPv4. If you add IPv6 to your network, you increase costs, complexity and operations. IPv4 is going to be around for 25 […]

Give your automated services credentials with Access service tokens

Give your automated services credentials with Access service tokens

Cloudflare Access secures your internal sites by adding authentication. When a request is made to a site behind Access, Cloudflare asks the visitor to login with your identity provider. With service tokens, you can now extend that same level of access control by giving credentials to automated tools, scripts, and bots.

Authenticating users and bots alike

When users attempt to reach a site behind Access, Cloudflare looks for a JSON Web Token (a JWT) to determine if that visitor is allowed to reach that URL. If user does not have a JWT, we redirect them to the identity provider configured for your account. When they login successfully, we generate the JWT.

When you create an Access service token, Cloudflare generates a unique Client ID and Secret scoped to that service. When your bot sends a request with those credentials as headers, we validate them ourselves instead of redirecting to your identity provider. Access creates a JWT for that service and the bot can use that to reach your application.

Getting started

Within the Access tab of the Cloudflare dashboard, you’ll find a new section: Service Tokens. To get started, select “Generate a New Service Token.”

A Free and Open Course on Data Protection in the Post-GDPR World

Last year, we published “The Dawn of New Digital Rights for Finnish Citizens,” about the launch of the New Digital Rights MOOC, a collaboration between Open Knowledge Finland and the Internet Society’s Finland Chapter. Raoul Plommer wrote, “The aim of the project is to make citizens more aware of their digital rights, initially focusing on explaining GDPR (General Data Protection Regulation) and MyData…through a MOOC platform and series of workshops that create content and train people and organizations to use it.” Plommer has written an update on the project:

We have come a long way from the beginning of last year, when we were given funding for the project from Internet Society’s Beyond the Net Funding Programme, and Eurooppatiedotus, which is a sub-organization of the Finnish Foreign Ministry.

It took us several months to agree on what is essential to know about the General Data Protection Regulation (GDPR) and how we would present it to the general public. It was also challenging to get all the content done without actually paying everyone for all their hard work. Both of our funders had a strict limit on how much money could be spent on salaries (15% and 30%). On Continue reading

How much memory is installed and being used on your Linux systems?

There are numerous ways to get information on the memory installed on Linux systems and view how much of that memory is being used. Some commands provide an overwhelming amount of detail, while others provide succinct, though not necessarily easy-to-digest, answers. In this post, we'll look at some of the more useful tools for checking on memory and its usage.Before we get into the details, however, let's review a few details. Physical memory and virtual memory are not the same. The latter includes disk space that configured to be used as swap. Swap may include partitions set aside for this usage or files that are created to add to the available swap space when creating a new partition may not be practical. Some Linux commands provide information on both.To read this article in full, please click here

IPv6 Buzz 019: IPv6 And Broadband Internet Cable Providers

In the latest episode of IPv6 Buzz we examine IPv6 deployment among cable providers. We'll discuss industry trends, financial and technical drivers for adoption, and how the cable industry is working to transition IPv4 out of the providers' access and distribution networks. Our guest is Dan Torbet.
