BrandPost: Performance Drives Innovation and Security Vendors Need to Keep Up

In 1969, the very first e-message was sent over the ARPANET from computer science Professor Leonard Kleinrock's UCLA laboratory to a network node located at Stanford. That event kicked off a digital revolution that has utterly transformed our world. And ever since that first defining moment, the one question that has driven nearly all subsequent digital innovation has been: “How can we do this even faster?”We are still wrestling with that same challenge today. The latest advances in computing, such as edge device hyperconnectivity and the hyperscalability achievements of advanced data center architectures are the result of the desire to achieve better performance. Speed is the driving force behind the digital transformation of today’s business infrastructures. It enables access to critical data and resources, drives business efficiencies, scales application development, increases productivity, generates revenue, and accelerates ROI.To read this article in full, please click here

Setting up K8s on AWS with Kubeadm and Manual Certificate Distribution

Credit for this post goes to Christian Del Pino, who created this content and was willing to let me publish it here.

The topic of setting up Kubernetes on AWS (including the use of the AWS cloud provider) is a topic I’ve tackled a few different times here on this site (see here, here, and here for other posts on this subject). In this post, I’ll share information provided to me by a reader, Christian Del Pino, about setting up Kubernetes on AWS with kubeadm but using manual certificate distribution (in other words, not allowing kubeadm to distribute certificates among multiple control plane nodes). As I pointed out above, all this content came from Christian Del Pino; I’m merely sharing it here with his permission.

This post specifically builds upon this post on setting up an AWS-integrated Kubernetes 1.15 cluster, but is written for Kubernetes 1.17. As mentioned above, this post will also show you how to manually distribute the certificates that kubeadm generates to other control plane nodes.

What this post won’t cover are the details on some of the prerequisites for making the AWS cloud provider function properly; specifically, this post won’t discuss:

The Never-Ending “My Overlay Is Better Than Yours” Saga

I published a blog post describing how complex the underlay supporting VMware NSX still has to be (because someone keeps pretending a network is just a thick yellow cable), and the tweet announcing it admittedly looked like a clickbait.

[Blog] Do We Need Complex Data Center Switches for VMware NSX Underlay

Martin Casado quickly replied NO (probably before reading the whole article), starting a whole barrage of overlay-focused neteng-versus-devs fun.

5 hot network-automation startups to watch

With the combined challenges of tight IT budgets and scarcer technical talent, it’s becoming imperative for enterprise network pros to embrace automation of processes and the way infrastructure responds to changing network traffic.Not only can automation help address these problems, they can also improve overall application-response time by anticipating and addressing looming congestion. Modern applications, such as virtual reality and artificial intelligence, and architectures that incorporate IoT and hybrid cloud have yet to reach their true potential because network capacity seems to always lag behind demand.  A common problem is that too much networking infrastructure is still manually maintained and managed, but major vendors are starting to addressing these  issues, as are startups that seek to break bottlenecks through automation.To read this article in full, please click here

Important Health Checks for your MySQL Master-Slave Servers

In a MySQL master-slave high availability (HA) setup, it is important to continuously monitor the health of the master and slave servers so you can detect potential issues and take corrective actions. In this blog post, we explain some basic health checks you can do on your MySQL master and slave nodes to ensure your setup is healthy. The monitoring program or script must alert the high availability framework in case any of the health checks fails, enabling the high availability framework to take corrective actions in order to ensure service availability.
