3 Ways to Run Kubernetes on AWS

Kubernetes is hugely popular and growing, and is primarily used on the cloud — 83 percent of organizations included in a large CNCF survey said they run Kubernetes on at least one public cloud. Amazon is a natural option for Kubernetes clusters, due to its mature and robust infrastructure, and a variety of deployment options with a varying degree of automation.

Go Big With Pseudo-Versions and GoCenter

Go modules have helped bring order to Go development, but there’s been some disorder lurking. Managing module pseudo-versions can be difficult, especially with some of the latest changes to Go. JFrog GoCenter, the free repository of versioned Go modules, now includes some important updates that can help you stay on course. Let’s take a look at how pseudo-versions work, and what you can expect from those changes. We also offer some guidance on keeping your Go builds working as you upgrade to Go 1.13 and later.

Advanced Git with the Free University of Tbilisi

On Monday, March 16, 2020, I had the privilege to (virtually) join Shota Gvinepadze and his students at the Free University of Tbilisi and speak about “Advanced Git @ Mattermost” for a portion of their class time.

Keep in mind that the command line examples are illustrative of my workflow, and not meant to be run in isolation.

How to Keep IT Infrastructure Fresh and Fit for Purpose

As a network evolves over time, new devices are added, old devices begin to show their age, and some devices are completely forgotten about. It’s a natural consequence of mergers, upgrades, staff turnovers, and other common occurrences that contribute to redundancy or excess complexity in IT infrastructure.

Introducing template variable saved views for dashboards

Datadog dashboards provide immediate visibility and insight into your environments. Setting template variables enables you to filter your dashboard graphs on the fly to visualize specific sets of tagged objects.

Live Kubernetes Debugging with the Elastic Stack

Your Kubernetes app is down. Your users start ranting on Twitter. Your boss is standing right behind you. What do you do? We are using the Elastic Stack in this demo with a special focus on its Kubernetes integration with metadata enrichment and autodiscovery in combination with APM / tracing, metrics, logs, and health checks.

Using the Beacon API

Users are so annoying! There they go, leaving the page before we can save the data to the API. Back in the old days, we would attach a `window.unload` handler and try to send an AJAX request, but this was slow and unreliable. Enter the Beacon API to give us a better way. The Beacon provides a reliable way to send a small amount of data *after* the page has been unloaded. It's not bound to the lifetime of the page and it doesn't slow down the user.
