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.

For many SREs, networking prompts a similar response as going to the dentist. You know you should do it, but you don’t really want to. But networking is much less like a root canal and more like a regular teeth cleaning; you may not want to go, but once you’re there, it’s not so bad. In fact, you may walk away feeling good knowing that you’ve done something that helps future you.

In a world where organizations store and process more data with each passing year, technology has evolved to keep pace. For example, hard drive capacities have increased steadily and adoption of scalable cloud storage platforms has headed skyward. At the same time, storage vendors have introduced solutions to accelerate storage read and write times — which have historically been a bottleneck in computing.

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.

In this blog series, we’ll explore a few different ways that Rancher uses TLS certificates. TLS, or Transport Layer Security, is a cryptographic protocol used to secure network communication. It is the successor to the now-deprecated Secure Sockets Layer, or SSL. You can expect to walk away with an understanding of how TLS integrates into various Rancher components, and how you can prepare your environment to properly leverage TLS in Rancher.

So, you’ve installed Coralogix’s STA and you would like to start analyzing your traffic and getting valuable insights but you’re not sure that you’re mirroring enough traffic or wondering if you might be mirroring too much data and could be getting more for less. The harsh truth is that in order to be able to detect everything, you have to capture everything and in order to be able to investigate security issues thoroughly, you need to capture every network packet.

The Organization: Home Healthcare Provider with over 30 locations across the U.S.

We have made much of why we went with Rancher’s k3s to underpin Civo’s managed Kubernetes service in posts such as Andy’s explanation of k8s vs k3s, but I wanted to take a bit of a deeper dive into k3s and why in particular it is a great technological choice for a service such as ours.
