The Inevitable Slowdown In Server Spending

It had to happen sooner or later, and really, the wonder is that it hasn’t already happened, given the nature of the infrastructure buildouts at hyperscalers and cloud builders, the skittishness of enterprises due to the trade war between the United States and China, the uncertainty in Europe over the British exit, and general concern with macroeconomic issues because it has now been almost twelve years since the last recession. …

Fast WordPress Sites with Bluehost & Cloudflare Workers

WordPress is the most popular CMS (content management system) in the world, powering over a third of the top 10 million websites, according to W3Techs.

WordPress is an open source software project that many website service providers host for end customers to enable them to build WordPress sites and serve that content to visitors over the Internet.  For hosting providers, one of the opportunities and challenges is to host one version of WordPress on their infrastructure that is high performing for all their customers without modifying the WordPress code on a per customer basis.

Hosting providers are increasingly turning to Cloudflare’s Serverless Workers Platform to deliver high performance to their end customers by fixing performance issues at the edge while avoiding modifying code on an individual site basis.

One innovative WordPress hosting provider that Cloudflare has been working with to do this is Bluehost, a recommended web host by WordPress.org. In collaboration with Bluehost, Cloudflare’s Workers have been able to achieve a 40% performance improvement for those sites running Workers. Bluehost started with Cloudflare Workers code for Fast Google Fonts which in-lines the browser-specific font CSS and re-hosts the font files through the page origin. This removes the multiple Continue reading

Flaw found in Supermicro motherboards could allow for remote hijacking

A security group discovered a vulnerability in three models of Supermicro motherboards that could allow an attacker to remotely commandeer the server. Fortunately, a fix is already available.Eclypsium, which specializes in firmware security, announced in its blog that it had found a set of flaws in the baseboard management controller (BMC) for three different models of Supermicro server boards: the X9, X10, and X11.[ Also see: What to consider when deploying a next-generation firewall | Get regularly scheduled insights: Sign up for Network World newsletters ] BMCs are designed to permit administrators remote access to the computer so they can do maintenance and other updates, such as firmware and operating system patches. It’s meant to be a secure port into the computer while at the same time walled off from the rest of the server.To read this article in full, please click here

Highly Available Kubernetes Clusters on AWS with Cluster API

In my previous post on Kubernetes Cluster API, I showed readers how to use the Cluster API provider for AWS (referred to as CAPA) to instantiate a Kubernetes cluster on AWS. Readers who followed through the instructions in that post may note CAPA places all the nodes for a given cluster in a single AWS availability zone (AZ) by default. While multi-AZ Kubernetes deployments are not without their own considerations, it’s generally considered beneficial to deploy across multiple AZs for higher availability. In this post, I’ll share how to deploy highly-available Kubernetes clusters—defined as having multiple control plane nodes distributed across multiple AZs—using Cluster API for AWS (CAPA).

This post assumes that you have already deployed a management cluster, so the examples may mention using kubectl to apply CAPA manifests against the management cluster to deploy a highly-available workload cluster. However, the information needed in the CAPA manifests would also work with clusterctl in order to deploy a highly-available management cluster. (Not familiar with what I mean when I say “management cluster” or “workload cluster”? Be sure to go read the introduction to Cluster API post first.)

Also, this post was written with CAPA v1apha1 in mind; a new Continue reading

How to Find Singles Networking Events

Busy working singles usually don’t have time for many hobbies or social outings, let alone time to date. That’s where singles networking events come in handy. They may be social or work-related and could be used to form a romantic connection with someone or just to network professionally. 

Types of Singles Networking Events

Singles networking events run the gambit from purely social to purely business and everything in between. Here are some examples of types of singles networking events.

Parents without Partners

This is a group of single parents who share information and experiences on raising their children, dating with children, and raising children without a co-parent in the home. 

Single Professional Groups

Some of these groups meet for purely professional reasons, and some to make both professional and personal connections. If you’re a member of a professional association related to your career, attend their membership meetings to find other professionals for networking purposes.

Speed Dating

The act of speed dating among singles is arranged by churches, clubs, and more.

Meetup.com

If you’re looking to make friends with people who have similar interests, search this website for local group outings near you. It may lead to new Continue reading

6 years of tech evolution, revolution and radical change

Exactly six years ago today—Sept. 5, 2013—Network World published my very first TechWatch blog post. It addressed the introduction of Samsung's Galaxy Gear and the problem with smartwatches.Since then, I’ve written hundreds of blog posts on a dizzying array of technology topics, ranging from net neutrality to phablets to cloud computing to big data to the internet of things (IoT)—and many, many more. It’s been a great ride, and I will be forever grateful to my amazing editors at Network World and everyone who’s taken the time to read my work. But all good things must come to an end, and this will be my last TechWatch post for Network World.To read this article in full, please click here

Measure Twice, Cut Once: Ansible net_interface

As I was preparing the materials for Ansible 2.7 Update webinar sessions I wanted to dive deeper into declarative configuration modules, starting with “I wonder what’s going on behind the scenes”

No problem: configure EEM applet command logging on Cisco IOS and execute an ios_interface module (more about that in another blog post)

Next step: let’s see how multi-platform modules work. Ansible has net_interface module that’s supposed to be used to configure interfaces on many different platforms significantly simplifying Ansible playbooks.
