In today’s post, we will be looking into a software design pattern called Facade. When I first adopted it, it felt a little bit awkward, but the more I used it in my Rails apps, the more I started to appreciate its usefulness. More importantly, it allowed me to test my code more thoroughly, to clean out my controllers, to reduce the logic within my views and to make me think more clearly about an application’s code’s overall structure.
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.
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 unplanned and unbudgeted surge in remote workers is creating new requirements and challenges for IT management. Understanding how these changes impact the IT infrastructure and worker’s effectiveness is vital to business continuity. Goliath offers the following out-of-the box reports that can help to better document key performance indicators and activity for the remote workforce.
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.
At re:Invent in December, Amazon announced the AWS Graviton2 processor and its forthcoming availability powering Amazon EC2 M6g instances. While the first-generation Graviton processor that powered A1 instances was better suited to less compute-intensive workloads, this processor is intended to offer AWS customers a compelling alternative to conventional x86-powered instances on both performance and cost.
Rostyslav Kosmirak is a .NET developer from Ivano-Frankivsk, Ukraine using Rider and Visual Studio IDE. Kosmirak was not looking for a Dynamic Code Profiler when he came across Prefix. Kosmirak explains that initially he was searching through Google for a log management system when he stumbled on Prefix. Upon downloading, Kosmirak discovered hidden performance problems in his code before they manifested to actual performance problems.
