It was a cloudy winter morning when I had arrived at the office and found, to our horror, that a Kubernetes cluster was suffering from extremely high CPU and network usage and had become almost completely non-functional. To make things worse, restarting the nodes (the go-to DevOp solution), seemed to have absolutely no effect on the issue. Something was poisoning the network and we had to find out what it was and fast.
The National Institute of Standards and Technology (NIST), a physical sciences laboratory and a non-regulatory agency of the United States Department of Commerce, recently released their guidelines for password security. Some of them are contrary to what we’ve come to believe are good password policies. Our IT security expert will talk more about these guidelines in our upcoming webinar. Let’s take a look at what some of them are.
If software's been eating the world for the past twenty years, it's safe to say machine learning has been eating it for the past five. But what exactly is machine learning? Why should a web developer care? This article by Julie Kent answers these questions. I don't have kids yet, but when I do, I want them to learn two things: Whether or not you believe that the singularity is near, there's no denying that the world runs on data.
Prometheus is an open-source system for monitoring and alerting originally developed by Soundcloud. It moved to Cloud Native Computing Federation (CNCF) in 2016 and became one of the most popular projects after Kubernetes. It can monitor everything from an entire Linux server to a stand-alone web server, a database service or a single process. In Prometheus terminology, the things it monitors are called Targets. Each unit of a target is called a metric.
The evolution of Security Information and Event Management (SIEM) is deeply intertwined with cloud computing, both in terms of technological breakthroughs the cloud provided and from its inherent security challenges. With the rise of cloud computing, we no longer rely on long-lived resources. An ephemeral infrastructure obscures the identity of the components and, even if you do have the visibility it doesn’t necessarily mean you can comprehend the meaning behind the components.
The Grafana v6.7 stable release includes improvements to Authorization and Enterprise reporting as well as a new plugin for Google Sheets. Check out the details below.
With the majority of the workforce working remotely due to COVID-19, DevOps teams are still focused on delivering reliable, performant services. In these challenging times, ensuring that infrastructure and applications are available at their highest level is even more imperative—and worthy of recognition. We are all in this together, and in the spirit of supporting each other, we are excited to announce our Observability All-Star program.
