When it comes to evaluating the quality of your software, there is usually no way around automated load tests. Locust has proven to be a mature tool to swarm your system with millions of simultaneous users to test your applications. However, while the definition and execution of tests can be…

I often have the need to run a workload on Kubernetes, but just temporarily and therefore I don’t want to create a fully-fledged cluster in the cloud. Some smaller, local setup often works in my case and I believe this would be the case for a lot of developers. Enter k3s/d RancherLab…

A Quick Recap In Part-1 of this blog series, we discussed the need for chaos engineering within continuous delivery pipelines and how LitmusChaos integrates with Keptn via a ready-made integration to facilitate the implementation of chaos stages. …

TL;DR The Keptn project started as an initiative to help organizations adopt cloud-native concepts for either their cutting-edge microservice applications or their monoliths that have matured over years. Focusing on robust continuous-delivery with automated testing, quality gates, and auto-remediation capabilities, the Keptn ecosystem has been growing since its inception. …

I was finally taking my Certified Kubernetes Application Developer (CKAD) exam last weekend. In this article, I want to briefly reflect on how I prepared for it, what helped me most, and which mistakes I made (and you should avoid). Although there are already a couple of blogs out there…

Prometheus is considered a foundational building block when running applications on Kubernetes and it has become the de-facto open-source standard for visibility and monitoring in Kubernetes environments. In this blog we are highlighting the most common challenges for operators of Prometheus as well as SREs, and provide guidance on how…

Google’s Book on Site Reliability Engineering has been a catalyst to have SRE’s, Performance and DevOps Engineers, or Cloud Operations incorporate the concept of Service Level Indicators (SLIs), e.g: 95th percentile of your service’s response time Service Level Objectives (SLOs), e.g: response time must not exceed 200ms during peak load …

When running and operating your microservices on Kubernetes, a service mesh might comes in handy to control and manage traffic within your cluster as well as to regulate which services are exposed to the public. Securing your Ingress Gateway via HTTPS with Let’s Encrypt is a common choice. However, setting…

When it comes to bringing new features to your users, you spend your time on designing, developing, and testing the features. However, customer value is only created once those features are released to your end-users. Naturally, you want to avoid any issues when releasing new features. Therefore, the principles of…
