Digital Experience Monitoring (DEM) is a growing practice within IT organizations that provides insight into the factors that make up the overall application User Experience (UX). As systems become more complex, as cloud adoption continues to grow, and IT loses direct control of infrastructure, it becomes both more difficult and more important to capture the overall end-user experience.

Since AWS Lambda was launched in 2014, serverless has transformed the way applications are built, deployed, and managed. By abstracting away the underlying infrastructure, developers are able to shift operational responsibilities to the cloud provider and focus on solving customer problems.

Recently, I had a scenario in which it was necessary to access the content of the source JSON message and extract a property that contains a date-time. That property was in the last object (a repeating object) for control purposes, and my first idea was to get it done with Azure Function and that’s it. But then I was thinking, if I need to use Function for all these simple tasks, what’s the point?

An IT service desk is an integral part of an organization’s IT operations. It’s relevant for entities of all sizes, and plays a key role in making sure that IT services meet key business objectives. In an organization, a service desk also acts as a catalyst for digital transformation, which is a major trend affecting almost every industry. In a recent report from Forturum, 41.4% of their respondents (companies) had a dedicated digital transformation team.

PromQL is the querying language that is part of Prometheus. In addition to PromQL, Prometheus provides a scraper that fetches metrics from instances (any application providing metrics) and a time series database (TSDB), which stores these metrics over time. This introduction to PromQL will be largely decoupled from specific tools and the non-PromQL parts of Prometheus, in order to focus on the features of the language itself.

Today, we will dive into one of the hard parts of using any monitoring - making sense out of all the data that is emitted. We think this is one of the hard parts. And being developers building for developers, we think a lot like you do – we think. Pun intended. Nowadays, we monitor AppSignal with AppSignal (on a separate setup), so we are still dogfooding all the time. We still run into challenges as you do, often before you.

Monitor Kubelet is key when running Kubernetes in production. Kubelet is a very important service inside Kubernetes’ control plane. It’s the component that cares that the containers described by pods are running in the nodes. Kubelet works in a declarative way by receiving PodSpecs and ensuring that the current state matches desired pods.

For those who don't know me, I'm a former SCOM admin, and I blog regularly about monitoring and co-organise Experts Live India each year. As one of SquaredUp's tech evangelists, I've recently taken on the task of figuring out Azure Monitor and documenting my journey so that others can find my — sometimes torturous — journey less taxing. This write-up is for you, hope you enjoy!

You know Big-O is important - not only for acing your next job interview but for knowing how code works at scale. But have you ever taken the time to go beyond a superficial understanding of the subject? In this article, Julie Kent uses equal parts math and Ruby to reveal the beating heart of Big-O and show us how it ticks.

Is your organization going through a DevOps transformation? Perhaps you’ve even been tasked to head up the project. And surely, part of this transformation is going to include source control management. More and more enterprise companies are using Git to manage their code and file changes. One of the most popular Git hosting services for large teams, particularly those partial to Microsoft’s robust suite of developer tools, is Azure DevOps.
